Canada is one of the countries best represented on iNaturalist, but there are still many geographic areas without iNaturalist activity, and many species still missing or poorly represented.</p> <p>We’ve partnered with the Canadian Wildlife Federation to try and fill these gaps. Can you help in a national scavenger hunt?</p> <p>Here are maps showing the locations of Canada museum specimens of species still missing from Canada on iNat.

Now is a good time to upload your backlog. </p> <h3>How you can help outside of Canada</h3> <p>Do you have expertise in any of these taxa? It’s possible that some of these species are already on iNaturalist, but they haven’t been identified yet. You can help by reviewing the <a href="/observations/identify?place_id=6712" rel="nofollow noopener">observations from Canada that need identification</a>. </p> <p>Even if you don’t have expertise in Canadian species, you may be able to help clean up some misidentifications. You can filter for observations that may be far out of their known range by <a href="/observations/identify?order_by=geo_score&order=asc&place_id=6712&with_private_location=false&expected_nearby=false" rel="nofollow noopener">sorting the "Identify" page by ascending geo score</a>. The <a href="https://www.inaturalist.org/blog/99727-using-the-geomodel-to-highlight-unusual-observations" rel="nofollow noopener">geo score</a> is a measurement of how typical an observation’s location is for that species – the higher the score, the more typical. Observations with low geo scores could be exciting range extensions, cultivated plants or captive animals that should be properly marked, or misidentifications. </p> <p>We look forward to seeing what you find!</p> </div> <div class="meta"> Posted on <span class="date">March 31, 2025 03:41 PM</span> by <a title="loarie" href="https://www.inaturalist.org/people/loarie"><img alt="loarie" title="loarie" srcset="https://static.inaturalist.org/attachments/users/icons/477/mini.png?1709012283 1x, https://static.inaturalist.org/attachments/users/icons/477/thumb.png?1709012283 2x" style=" max-width: 16px" class="user_image usericon " src="https://static.inaturalist.org/attachments/users/icons/477/mini.png?1709012283" /> </a><a title="loarie" href="https://www.inaturalist.org/people/loarie">loarie</a> | <span class="count">23</span> comments | <a href="/blog/108240-help-find-these-missing-canadian-species#new_comment">Leave a comment</a> </div> </div> <div class="column-separator"> <img src="https://www.inaturalist.org/assets/logo-eee-15px-8f26cb7404257fa9b8ee143ca65be95b53e98e56f81ff1678848b9e3ae2e13ee.png"> </div> </div> <h2 class="date grouped_date">March 25, 2025</h2> <div class="posts"> <div class="post" id="post-108332"> <h3 class="title media-heading"> <a href="/blog/108332-australian-sea-centipede-that-s-the-color-of-lime-jell-o-observation-of-the-week-3-25-25">Australian Sea Centipede That's the Color of Lime Jell-O? - Observation of the Week, 3/25/25</a> </h3> <div class="body clear"> <p align="center"><img src="https://static.inaturalist.org/wiki_page_attachments/4394-original.jpg" style="width: 100%"></p> <p>Our Observation of the Week is this <a href="https://www.inaturalist.org/observations/264419988" rel="nofollow noopener"><i>Paridotea ungulata</i></a> isopod, seen in <a href="https://www.inaturalist.org/observations?place_id=6744" rel="nofollow noopener">Australia</a> by <a href="https://www.inaturalist.org/people/moth_nut" rel="nofollow noopener">@moth_nut</a>!</p> <p>Currently living in Tasmania and working with the <a href="https://www.anu.edu.au/" rel="nofollow noopener">Australian National University</a> and researching habitat suitability, threats, and effective management strategies for some of Australia’s most endangered birds, Tom Hunt’s childhood was spent in the Adelaide Hills of <a href="https://www.inaturalist.org/observations?place_id=6899" rel="nofollow noopener">South Australia</a>. </p> <p><i>Surrounded by bushland and birds, I have been a keen nature lover and photographer for as long as I can remember. That passion eventually shaped my career, taking me across Australia as an ecologist working on conservation projects.</i></p> <p><i>My work is driven by a desire to help, in some small way, to reverse Australia’s alarming extinction rates and protect the wildlife that makes this country so special. As such, I have a particular interest in threatened species monitoring and management. After studying at The University of Adelaide, I spent over a decade working on conservation and restoration projects in South Australia, Victoria, and New South Wales. This included researching endangered mallee birds and reintroducing locally extinct mammals through the Wild Deserts project.</i></p> <p>Now that he’s in Tasmania, Tom’s begun to explore coastal habitats in earnest.</p> <p><i>My partner and I soon found ourselves spending more time exploring the coastline – beachcombing, rockpooling, snorkelling, and diving – using iNaturalist to log and learn about the things we saw. One of our most exciting discoveries came after I saw a few iNat observations of a beautiful sea centipede (Paridotea ungulata) in my local marine reserve at Tinderbox – a rugged peninsula in southern Tasmania fringed by rocky reefs and cold-water kelp forests. I had no idea sea centipedes even existed until I found these local records!</i></p> <p align="center"><img src="https://static.inaturalist.org/wiki_page_attachments/4395-original.jpg" style="width: 80%"></p> <p><i>One weekend as we were exploring a shallow bay on the Tinderbox Peninsula, we spotted something bright green attached to a floating piece of </i><a href="https://www.inaturalist.org/taxa/124748-Macrocystis-pyrifera" rel="nofollow noopener"><i>Giant Kelp</i></a><i> . Intrigued, I swam over for a closer look – and to my delight, it was a Paridotea ungulata. Its vibrant, electric-green body clung tightly to the kelp with its specialised grasping legs. I brought it to shore for a quick photograph before releasing it back into the water. Watching it swim away using its valve-like </i><a href="https://en.wikipedia.org/wiki/Uropod" rel="nofollow noopener"><i>uropod</i></a><i> to propel itself in a rippling motion – remarkably reminiscent of a writhing centipede – was mesmerising.</i></p> <p><i>As an ecologist, few things are as thrilling as encountering a species from a completely new taxonomic group, even more so when you have been given the background knowledge from a source like iNaturalist to make you realise what a special creature it is. My fascination with marine life continues to grow, and I’ll be keeping an eye out for more sea centipedes amongst the host of other exciting finds that await us here.</i></p> <p>Isopods like the one seen here belong to the suborder <a href="https://www.inaturalist.org/taxa/343778-Valvifera" rel="nofollow noopener">Valvifera</a>, marine isopods commonly known as valvetails due to their valve-like uropods. You can often find them clinging to kelp and other objects if you’re doing some coastal exploration.</p> <p align="center"><img src="https://static.inaturalist.org/wiki_page_attachments/4393-original.jpg" style="width: 80%"></p> <p>Tom (above) joined iNat almost exactly five years ago and wrote some wonderful paragraphs about it to me, so I’ll just present them here in full. </p> <p><i>As a passionate wildlife observer, I use iNaturalist to document the species I encounter – whether at home, on hikes, or while working in the field. For species I’m familiar with, it’s rewarding to log observations in less-visited areas, contributing valuable distribution data. For those I don’t recognise, iNaturalist is like carrying the world’s most comprehensive field guide in my pocket, helping me identify species and discover what I might encounter on my next adventure. It has also helped spark an interest in so many more taxa, from moths and mantises to peas and Proteaceae!</i></p> <p><i>As a researcher, iNaturalist has been an invaluable tool for tracking species distributions and uncovering unusual records. But just as importantly, it allows me to give back – helping others identify wildlife using my own ecological knowledge, particularly given that these contribute to publicly available datasets I frequently use in my work.</i></p> <p><i>One of the most powerful aspects of iNaturalist is its ability to spark curiosity and fuel deeper exploration. The natural world can feel overwhelming – many people don’t know where to begin if they can’t already identify species; the trick is simply having a starting point. Learning a few common species creates a foundation for recognising what’s unfamiliar, making it easier to notice patterns, compare features, and find more information. Traditionally, this kind of knowledge required access to field guides, a mentor, or higher-education study – resources that aren’t always available for many people, especially for lesser-known taxa, or in remote and less-studied regions.</i></p> <p><i>iNaturalist changes this. It’s a free, dynamic, and constantly growing resource that offers detailed, location-based species lists, computer-vision powered ID suggestions, and direct connections to experts. It provides instant feedback and a fast track to deeper engagement with the natural world – across all observable taxa.</i></p> <p><i>In this way, I think iNaturalist is truly game-changing. It doesn’t replace field guides, taxonomic expertise, or academic research, but it enhances them. By creating a two-way exchange of knowledge between citizen scientists and experts, it also accelerates research, conservation, and public interest in nature.

Since then he’s become a phenomenal macro photographer who has his own very helpful <a href="https://www.youtube.com/@naturefold" rel="nofollow noopener">YouTube channel</a>, was named the <a href="https://www.nhm.ac.uk/wpy/gallery/2024-life-under-dead-wood" rel="nofollow noopener">Young Wildlife Photographer of the Year in 2024</a> by the Natural History Museum, and added over 100k identifications on iNaturalist! </p> <p>Half Greek and half Canadian, Alexis was born in Germany and has lived there his entire life. </p> <p><i>I spent a lot of time outside in nature as a little kid, and with several close relatives being biologists that scientific view on the natural world was always present for me. I started birdwatching around age 7, and in the 11 years or so since, nature observation in general has become a big part of my life. In the last 5 years, especially through the pandemic, my interest has shifted more toward smaller arthropods, though I am fascinated by all kinds of wildlife.</i></p> <p>Alexis’s identification habits have followed a similar trajectory: </p> <p><i>I used to mostly identify European bird observations, but stopped a few years ago as my focus shifted away from birding. In the last few years I have become fascinated by </i><a href="https://www.inaturalist.org/taxa/49470-Collembola" rel="nofollow noopener"><i>Springtails</i></a><i>, and they account for the vast majority of my IDs since then. While I don't have much time for identifying these days, I try and go through recent observations whenever I have the chance and help out on any observations I've been tagged in. [Alexis is among the top </i><a href="https://www.inaturalist.org/observations?verifiable=true&taxon_id=49470&view=identifiers&place_id=any" rel="nofollow noopener"><i>identifiers of springtail observations</i></a><i>, with nearly 15k as of this writing. - TI] </i></p> <p>Springtails are very tiny arthropods that are found basically anywhere where soil or similar conditions exist. They are <a href="https://www.inaturalist.org/taxa/372739-Hexapoda" rel="nofollow noopener">hexapods</a> but separate from insects, and they rarely grow more than 6mm in length. Most eat plant and fungal material, but some are predatory. In addition to being <a href="https://www.inaturalist.org/observations?order_by=votes&taxon_id=49470" rel="nofollow noopener">amazing looking</a>, most have a <a href="https://en.wikipedia.org/wiki/Furcula_(springtail)" rel="nofollow noopener">furcula</a>, or small appendage, folded under their abdomen which can be released so it hits against the substrate and propels the organism into the air - a good way to escape from predators. </p> <p>When identifying, Alexis will usually look up springtail observations in Europe, both at Needs ID and Research Grade levels. </p> <p><i>There are a good amount of local springtail species that are easy to ID/confirm, even with low quality photos - the problem is that there are just as many which are nearly impossible to get to species from photos. Along with the high portion of low quality smartphone photos and false positive AI IDs, this can make it quite a challenge to sift through springtail observations. Luckily I've accumulated a few good online resources and </i><a href="https://collembola.org/doc/genera.htm#Keys" rel="nofollow noopener"><i>keys</i></a><i> to help with identification, many of which are listed on collembola.org (a website that's great for finding comparison photos too).</i></p> <p><i>Along with the more general searches like this, sometimes I will pick out a certain genus or species and do a deeper dive on the ID features, so that I can go through a big batch of observations of that group to try and fix any mis-IDs. </i></p> <p>He’ll also collaborate with other springtail identifiers, such as in <a href="https://www.inaturalist.org/observations/259299048" rel="nofollow noopener">this observation</a>. He says,</p> <p><i>I've learned so much from the incredibly supportive iNat community, and I love being able to give some of that back through helping others. I also just enjoy the process, and I continue to learn a lot while identifying, whether through interactions with other springtail identifiers or looking closer at a species I am unfamiliar with.</i></p> <p><i>iNat was a big part of getting me more seriously into macro photography, and still plays an important role in my process for identifying and learning more about my subjects. Whenever I am traveling it's also interesting to look through observations in the area in advance, to see what I could find and what to look for.</i></p> <p align="center"><img src="https://static.inaturalist.org/wiki_page_attachments/4392-original.jpg" style="width: 80%"></p> <hr> <p>How does one go about finding and photographing springtails? Alexis has some tips:</p> <p><i>The easiest place to find a variety of springtails is in the leaf litter and on/dead wood on the forest floor. My usual method is just to look underneath dead wood in the forest, but there are springtail species adapted to just about any habitat (Including the high slopes of mount Everest and deep underground in caves). The main challenge is just spotting them, since most species are only a couple of millimeters in size or even smaller. Springtails are especially active (and come to the soil surface more) in moist conditions, so it's always worth taking a look after it has rained.</i></p> <p><i>[For photography] get as close as you can. If you have a camera and dedicated macro lens that's great, but even just with a phone there are lots of great options for cheap clip on macro/microscope lenses that allow you to get great close up images! Many springtails need details of the pattern to get an ID, so getting a top down angle is usually most important. Try and get other angles as well if you can, especially if you are unfamiliar with the species. Some springtails also just can't be identified to species from photos at all, so don't worry if an observation only gets to family or genus (although this happens just as much from a lack of springtail identifiers).</i></p> <p>I asked Alexis to name a favorite springtail of his and he chose the genus <a href="https://www.inaturalist.org/taxa/171607-Sminthurides" rel="nofollow noopener"><i>Sminthurides</i></a>:</p> <p><i>These are absolutely tiny and live at the edge of ponds and in swampy areas. They have a really fascinating courtship ritual, males have specialized antennae with which they clasp onto the antennae of the females. They “dance” around face to face like this on the water's surface, which is amazing to watch. I saw these for the first time last year and got </i><a href="https://www.inaturalist.org/observations/205208878" rel="nofollow noopener"><i>one of my favorite springtail photos to date</i></a><i>.</i></p> <hr> <p>- check out Alexis discussing his photography award in <a href="https://www.youtube.com/watch?v=TP-gJ7D7_wY&t" rel="nofollow noopener">this YouTube Video</a>!</p> <p>- <a href="https://www.inaturalist.org/people/frankashwood" rel="nofollow noopener">@frankashwood</a>’s giant springtail was an <a href="https://www.inaturalist.org/blog/86178-a-giant-springtail-observation-of-the-week-10-24-23" rel="nofollow noopener">Observation of the Week </a>back in 2023!</p> <p>- if you're not an expert you can definitely <a href="https://help.inaturalist.org/en/support/solutions/articles/151000185912" rel="nofollow noopener">help identify observations on iNaturalist by refining them</a>! </p> </div> <div class="meta"> Posted on <span class="date">March 19, 2025 05:52 PM</span> by <a title="tiwane" href="https://www.inaturalist.org/people/tiwane"><img alt="tiwane" title="tiwane" srcset="https://static.inaturalist.org/attachments/users/icons/28/cf84a7ca721527a34d18af824d0b687a-mini.jpg?1739340503 1x, https://static.inaturalist.org/attachments/users/icons/28/cf84a7ca721527a34d18af824d0b687a-thumb.jpg?1739340503 2x" style=" max-width: 16px" class="user_image usericon " src="https://static.inaturalist.org/attachments/users/icons/28/cf84a7ca721527a34d18af824d0b687a-mini.jpg?1739340503" /> </a><a title="tiwane" href="https://www.inaturalist.org/people/tiwane">tiwane</a> | <span class="count">43</span> comments | <a href="/blog/108055-identifer-profile-alexis_orion#new_comment">Leave a comment</a> </div> </div> <div class="column-separator"> <img src="https://www.inaturalist.org/assets/logo-eee-15px-8f26cb7404257fa9b8ee143ca65be95b53e98e56f81ff1678848b9e3ae2e13ee.png"> </div> <div class="post" id="post-108035"> <h3 class="title media-heading"> <a href="/blog/108035-curator-guide-update-one-month-flagging-period-for-vascular-plants-before-taxon-changes">Curator Guide Update: One-Month Flagging Period for Vascular Plants Before Taxon Changes</a> </h3> <div class="body clear"> <p>Happy <a href="https://www.internationaldays.co/event/taxonomist-appreciation-day/r/recrn5azUiUHm3QFu#:~:text=March%2019th%20is%20Taxonomist,and%20description%20of%20existing%20organisms." rel="nofollow noopener">World Taxonomist Appreciation Day</a>! In response to community feedback, we’re introducing a small update to vascular plant curation guidelines on iNaturalist. You can find it <a href="https://inaturalist.freshdesk.com/en/support/solutions/articles/151000023796-section-a-synonymizing-relationship-unknowns" rel="nofollow noopener">here</a>. But in short, for vascular plant curators should now wait for community feedback before resolving "Relationship Unknown" taxa, and we're also considering referencing World Flora Online for Ferns.</p> <h3>Background</h3> <p>For many branches of the taxonomy, iNaturalist follows external references. Keeping iNaturalist in sync with these references is a very important task for volunteer curators. For example, for birds we follow the <a href="https://www.birds.cornell.edu/clementschecklist/" rel="nofollow noopener">Clements Checklist</a> which updates annually. Thanks to the incredible hard work of curators like <a href="https://www.inaturalist.org/people/birdwhisperer" rel="nofollow noopener">@birdwhisperer</a> crafting taxon changes, iNaturalist is able to stay in sync with Clements as it updates. iNat staff are incredibly grateful for this dedicated volunteer curation work.</p> <p>For vascular plants, iNaturalist follows Kew’s <a href="https://powo.science.kew.org" rel="nofollow noopener">Plants of the World Online (POWO)</a> as our external reference. Under existing curator guidelines, taxon changes for "Relationship Unknown" taxa (i.e., taxa with no deviations) with fewer than 100 observations are typically made in the direction of the external reference without an embargo period or community review. For example, in the Heath Family that would include <i>Arbutus xalapensis var. texana</i> (30 obs) but not <i>Andromeda polifolia glaucophylla</i> (470 obs) <a href="https://www.inaturalist.org/taxon_frameworks/10/relationship_unknown?taxon_id%5D=133387" rel="nofollow noopener">here</a>.</p> <p><a href="https://www.inaturalist.org/taxon_frameworks/10/relationship_unknown?taxon_id%5D=133387" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4385-original.png" width="75%" style="border: 2px solid gray; border-radius: 5px; padding: 4px;"></a></p> <p>Many iNaturalist users have reached out to tell us that these curator guidelines do not give the community time to work with Kew to advocate for updates and fix errors on the POWO end.</p> <h3>New Experimental Policy</h3> <p>As a result, we’re introducing an experimental change: <b>curators should now open a flag and wait one month before making taxon changes to Vascular Plant "Relationship Unknown" taxa.</b> This allows time for community input before aligning with POWO.</p> <ul> <li>For taxa with existing flags, the month-long waiting period starts today and ends on <b>April 19</b>.</li> <li>If no feedback is received, or if there is community consensus that following POWO is advisable, curators may proceed with the taxon change after the waiting period.</li> </ul> <p>For example, for <i>Arbutus xalapensis var. texana</i> based on <a href="https://powo.science.kew.org/results?q=Arbutus%20xalapensis%20subsp.%20texana" rel="nofollow noopener">research on POWO</a> compose a <a href="https://www.inaturalist.org/flags/740281" rel="nofollow noopener">flag</a> like this: <br> <a href="https://www.inaturalist.org/flags/740281" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4386-original.png" width="75%" style="border: 2px solid gray; border-radius: 5px; padding: 4px;"></a></p> <h3>How to Contribute to POWO Improvements</h3> <p>If you have expertise in vascular plants, please <a href="https://www.inaturalist.org/flags?utf8=%E2%9C%93&flagger_type=any&flagger_name=&flagger_user_id=&user_name=&user_id=&flaggable_type=Taxon&taxon_name=Heath+Family&taxon_id=133387&deleted=any&flags%5B%5D=inappropriate&flags%5B%5D=other&reason_query=&resolved=no&resolver_name=&resolver_user_id=&commit=Filter&utf8=%E2%9C%93&flagger_user_id=&commit=Filter" rel="nofollow noopener">monitor flags</a> for your taxa of interest and help improve POWO by:</p> <ul> <li>Providing input on flags <ul> <li>If you support the change, leave a comment confirming that following POWO is appropriate.</li> <li>If you oppose the change, explain why and suggest alternative actions.</li> </ul> </li> <li>Requesting updates to POWO <ul> <li>If a taxon needs correction, you can contact Kew by emailing <a href="mailto:bi@kew.org" rel="nofollow noopener">bi@kew.org</a> to request an update.</li> <li>Since POWO only includes names registered in IPNI, you should submit names here: <a href="https://ipni.org/registration/" rel="nofollow noopener">https://ipni.org/registration/</a>.</li> <li>Please keep the flag discussion updated with any correspondence with Kew.</li> </ul> </li> <li>Creating a deviation when necessary <ul> <li>If Kew cannot update POWO in a timely manner, curators should create a taxon framework deviation to signal that iNaturalist is diverging from POWO.</li> </ul> </li> </ul> <p><a href="https://www.inaturalist.org/flags?utf8=%E2%9C%93&flagger_type=any&flagger_name=&flagger_user_id=&user_name=&user_id=&flaggable_type=Taxon&taxon_name=Heath+Family&taxon_id=133387&deleted=any&flags%5B%5D=inappropriate&flags%5B%5D=other&reason_query=&resolved=no&resolver_name=&resolver_user_id=&commit=Filter&utf8=%E2%9C%93&flagger_user_id=&commit=Filter" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4387-original.png" width="75%" style="border: 2px solid gray; border-radius: 5px; padding: 4px;"></a></p> <h3>Reviewing the Experiment</h3> <p>We’ll check in on this experiment in six months to assess:</p> <ul> <li>How many flags received no response.</li> <li>How many flags were uncontroversial and led to straightforward changes.</li> <li>How many flags were controversial, resulting in discussions, efforts to update POWO, or taxon deviations.</li> <li>POWO’s responsiveness to update requests.</li> </ul> <p>Based on these findings, we will develop a long-term curation plan for vascular plants on iNaturalist.</p> <h3>Exploring changing the referencing for Ferns to World Flora Online</h3> <p>There has been <a href="https://www.inaturalist.org/flags/271039" rel="nofollow noopener">long running debate</a> within the community about whether POWO is a good reference for the 'fern' vascular plant classes Lycopodiopsida and Polypodiopsida.

If we implement this change we'll announce it as an update to this post.</p> <p>Thank you for all your help observing, identifying, and curating plants on iNaturalist. Vascular plants are our largest group by <a href="https://www.inaturalist.org/observations?subview=map&taxon_id=211194" rel="nofollow noopener">number of observations</a>, so it makes sense that maintaining a well-curated taxonomy with broad community buy-in is challenging.

Maybe you've even participated, or noticed the surge of observations at the end of April. But what exactly is behind this global event?</p> <p>The CNC is a four-day bioblitz held every April. Cities around the world compete and collaborate to find species, make observations, and connect people with nature in urban areas. It started in 2016 as a friendly contest between San Francisco and Los Angeles. Since then, it has grown into an international event, with 690 cities and nearly 2,000 local organizers participating last year.</p> <h3>How is the City Nature Challenge organized?</h3> <p>The CNC was co-founded 10 years ago by Lila Higgins (<a href="https://www.inaturalist.org/people/lhiggins" rel="nofollow noopener">@lhiggins</a>), Rebecca Johnson (<a href="https://www.inaturalist.org/people/rebeccafay" rel="nofollow noopener">@rebeccafay</a>), and Alison Young (<a href="https://www.inaturalist.org/people/kestrel" rel="nofollow noopener">@kestrel</a>), leads of the Community Science teams at the <a href="https://nhmlac.org/community-science" rel="nofollow noopener">Natural History Museum of Los Angeles County</a> and the <a href="https://www.calacademy.org/community-science" rel="nofollow noopener">California Academy of Sciences</a>. Today, these two museums serve as the Global Organizing Team, working with local organizers worldwide.</p> <p>Each CNC city or metro area has one or more local organizers. These individuals come from diverse backgrounds, including students, educators, and environmental professionals. Local organizers are the heart of the CNC. They encourage their communities to explore and document nature using platforms like iNaturalist. Their efforts help expand the challenge and engage more people each year. The Global Organizing Team provides training, tools, and resources to help local organizers promote and implement the CNC in ways that fit their communities.</p> <p>City organizers often build partnerships with schools, local governments, and community groups to spread the word. They also coordinate events like bioblitzes, nature walks, and moth lighting to engage participants.</p> <p align="center"><img src="https://static.inaturalist.org/wiki_page_attachments/4301-original.JPG" style="width: 60%"></p> <p align="center"><small>CNC participants in Tuxtla Guitiérrez, Chiapas, Mexico.

This year, it's playing a bigger role than ever. With Alison Young (<a href="https://www.inaturalist.org/people/kestrel" rel="nofollow noopener">@kestrel</a>) moving to a new position as the <a href="https://www.inaturalist.org/pages/team" rel="nofollow noopener">Director of Outreach Programs</a>, iNaturalist is taking a more active role in the CNC in promoting the event and engaging the community. Expect more updates about the CNC as the event approaches!</p> <p align="center"><img src="https://static.inaturalist.org/wiki_page_attachments/4300-original.png" style="width: 80%"></p> <p align="center"><small>Results of the City Nature Challenge over the past nine years.</small></p> <h3>How can I participate in the City Nature Challenge?</h3> <p>Mark your calendar for CNC 2025!

While observers must make observations in participating cities or join the Global Project, anyone can help identify species worldwide. Taxon experts and dedicated iNaturalist users play a huge role in refining observations and guiding new participants. Every identification helps move observations closer to research-grade status and lets new users know their contributions matter.</p> <h4>We’re excited to bring the world together for biodiversity during the 10th City Nature Challenge!</h4> <p>Acknowledgement: Big thanks to the rest of the global organizing team: Amy Jaecker-Jones (<a href="https://www.inaturalist.org/people/amyjaecker-jones" rel="nofollow noopener">@amyjaecker-jones</a>) (NHM), Sam Tayag (<a href="https://www.inaturalist.org/people/songdog-st" rel="nofollow noopener">@songdog-st</a>) (NHM), and Olivia VanDamme (<a href="https://www.inaturalist.org/people/olivia_v" rel="nofollow noopener">@olivia_v</a>) (CAS) for continuing to devote part of their professional time to making the City Nature Challenge run.</p> </div> <div class="meta"> Posted on <span class="date">March 5, 2025 06:55 PM</span> by <a title="kestrel" href="https://www.inaturalist.org/people/kestrel"><img alt="kestrel" title="kestrel" srcset="https://static.inaturalist.org/attachments/users/icons/2692/mini.jpeg?1727914796 1x, https://static.inaturalist.org/attachments/users/icons/2692/thumb.jpeg?1727914796 2x" style=" max-width: 16px" class="user_image usericon " src="https://static.inaturalist.org/attachments/users/icons/2692/mini.jpeg?1727914796" /> </a><a title="kestrel" href="https://www.inaturalist.org/people/kestrel">kestrel</a> | <span class="count">31</span> comments | <a href="/blog/107296-celebrate-10-years-of-the-city-nature-challenge-with-inaturalist#new_comment">Leave a comment</a> </div> </div> <div class="column-separator"> <img src="https://www.inaturalist.org/assets/logo-eee-15px-8f26cb7404257fa9b8ee143ca65be95b53e98e56f81ff1678848b9e3ae2e13ee.png"> </div> <div class="post" id="post-107428"> <h3 class="title media-heading"> <a href="/blog/107428-that-s-one-ornate-tick-observation-of-the-week-3-5-25">That's One Ornate Tick! - Observation of the Week, 3/5/25</a> </h3> <div class="body clear"> <p align="center"><img src="https://static.inaturalist.org/wiki_page_attachments/4373-original.jpg" style="width: 100%"></p> <p>Our Observation of the Week is this <a href="https://www.inaturalist.org/observations/261964742" rel="nofollow noopener">Ornate Cow Tick</a> (<i>Dermacentor reticulatus</i>, Луговой клещ in Russian), seen in <a href="https://www.inaturalist.org/observations?place_id=7578&subview=map" rel="nofollow noopener">Belarus</a> by <a href="https://www.inaturalist.org/people/shapomacro" rel="nofollow noopener">@shapomacro</a>!</p> <p>Ticks! Most people (including myself, and I love arachnids) find them pretty creepy or gross, and obviously they can be very harmful as a disease vector, but as Andrey Shapolov’s eye and photography skills show, they can also be fascinatingly beautiful. “I just like them,” he tells me. “They look quite unusual and interesting. I like to photograph various parasites.”</p> <p>A macro photographer from Belarus, Andrey became interested in insect and arachnid photography in 2015, and says “I fell in love with nature and its small inhabitants.” The tick photos you see in this post were taken with the Canon MP-E65mm f/2.8 lens, which can provide up to 5x magnification, and are <a href="https://en.wikipedia.org/wiki/Focus_stacking" rel="nofollow noopener">focus stacks</a> of 78 and 198 images, respectively. </p> <p><i>I photographed this tick back in October 2024.

Yet, while satellites provide near-continuous imaging of the Earth, most species distribution datasets remain artisanal—often hand-drawn by experts or based on statistical correlations with indirect environmental variables like temperature rather than direct biodiversity observations.</p> <p>The iNaturalist Open Range Map Dataset is different:</p> <p>✅ <strong>Built on hundreds of millions of observations from the iNaturalist community.</strong><br> ✅ <strong>Improving each month as new observations are added.</strong><br> ✅ <strong>A true data-driven complement to traditional range maps, reflecting actual species occurrences.</strong></p> <h3>Mapping Species Richness at Scale</h3> <p>One way to showcase this dataset is by estimating terrestrial vertebrate species richness. The map below was generated by stacking <strong>12,000 individual range maps</strong> from the dataset, covering approximately <strong>30% of all terrestrial vertebrate species</strong> (12k out of 39k). Areas with higher species richness are shown in red.</p> <p>Despite known biases towards more 'charismatic' species in this subset of vertebrates, this estimate aligns with established biodiversity patterns, showing <strong>peak species richness in the tropics</strong>, similar to other global biodiversity assessments (e.g., <a href="https://www.sciencedirect.com/science/article/pii/S0169534713002358" rel="nofollow noopener">this study</a>).</p> <p><a href="https://static.inaturalist.org/wiki_page_attachments/4358-original.png" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4366-original.png" width="100%"></a></p> <p>Similarly, a map of <strong>small-ranged terrestrial vertebrates</strong> (species with range sizes smaller than the median for their group) highlights endemism hotspots in regions such as the <strong>Andes and Madagascar</strong>, corroborating findings from other biodiversity studies (e.g., <a href="https://www.pnas.org/doi/full/10.1073/pnas.1302251110" rel="nofollow noopener">this study</a>).<br> <a href="" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4367-original.png"></a></p> <h3>A Long Road Ahead—But a Clear Path Forward</h3> <p>The maps above focus on terrestrial vertebrates where <strong>30% of all species</strong> are in the model. However, the gaps are much larger for other groups. Across <strong>all described species</strong>, while <strong>iNaturalist has documented <a href="https://www.inaturalist.org/blog/103155-500-000-taxa-on-inaturalist" rel="nofollow noopener">~25%</a></strong>, we currently have enough <strong>observations to model only 5%</strong> of them.</p> <p><img src="https://static.inaturalist.org/wiki_page_attachments/4364-original.png" width="100%"></p> <p>However, where data exists, our models produce <strong>accurate, dynamically updated species distribution maps</strong>. This gives us hope: if we can <strong>continue growing the iNaturalist community and fill in species and geographic gaps</strong>, we can provide the conservation community with the <strong>high-quality, dynamically updated species distribution data</strong> it urgently needs.</p> <h3>Filling the Gaps—Together</h3> <p>To reach the next milestone—<strong>200,000 taxa modeled</strong>—we need to expand both <strong>taxonomically and geographically</strong>.</p> <ul> <li> <strong>Taxonomic Expansion:</strong> Observations of lesser-known species, such as <strong>insects, plants, and fungi</strong>, are critical for increasing coverage beyond well-documented terrestrial vertebrates.</li> <li> <strong>Geographic Expansion:</strong> The map below is a copy of the terrestrial vertebrate species richness map from above where <strong><a href="https://h3geo.org/docs/core-library/restable/" rel="nofollow noopener">H3-4 hexagons</a> with fewer than 100 observations of modeled species</strong> are grayed out. These gaps represent missing data, but they also represent <strong>an opportunity</strong>.</li> </ul> <p>By engaging more observers and identifiers worldwide, we can <strong>fill these gaps, refine our models, and build an open, data-driven map of life on Earth.</strong></p> <p><strong>Join us in making this vision a reality!</strong> Click the map to zoom in. Can you help spread the word about iNaturalist to help fill these gaps?</p> <p><a href="https://static.inaturalist.org/wiki_page_attachments/4344-original.png" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4365-original.png" width="100%"></a></p> </div> <div class="meta"> Posted on <span class="date">February 25, 2025 07:44 PM</span> by <a title="loarie" href="https://www.inaturalist.org/people/loarie"><img alt="loarie" title="loarie" srcset="https://static.inaturalist.org/attachments/users/icons/477/mini.png?1709012283 1x, https://static.inaturalist.org/attachments/users/icons/477/thumb.png?1709012283 2x" style=" max-width: 16px" class="user_image usericon " src="https://static.inaturalist.org/attachments/users/icons/477/mini.png?1709012283" /> </a><a title="loarie" href="https://www.inaturalist.org/people/loarie">loarie</a> | <span class="count">27</span> comments | <a href="/blog/106918-celebrating-100-000-modeled-taxa-with-the-inaturalist-open-range-map-dataset#new_comment">Leave a comment</a> </div> </div> <div class="column-separator"> <img src="https://www.inaturalist.org/assets/logo-eee-15px-8f26cb7404257fa9b8ee143ca65be95b53e98e56f81ff1678848b9e3ae2e13ee.png"> </div> <div class="post" id="post-107012"> <h3 class="title media-heading"> <a href="/blog/107012-new-computer-vision-model-with-over-100k-taxa">New computer vision model with over 100k taxa</a> </h3> <div class="body clear"> <p>We released v2.20 today which is our first model with over 100,000 taxa!

class="posts"> <div class="post" id="post-106449"> <h3 class="title media-heading"> <a href="/blog/106449-better-image-matches-photo-similarity-update-to-computer-vision-suggestions">Better Image Matches: Photo Similarity Update to Computer Vision Suggestions</a> </h3> <div class="body clear"> <p>Have you ever tried to identify a caterpillar and wished that the species suggestions didn’t just show you adult butterflies and moths? Now on the website you will see more relevant photos displayed in ID suggestions. </p><p>We’ve updated the <strong>Computer Vision Suggestions</strong> on the web to display <strong>Taxon Photos that are most visually similar</strong> to the observation photo. This improvement should make it easier to determine which suggestions are the best match—<strong>across all taxa!</strong> We're highlighting insects here but it works for plants and fungi, too!</p> <h3>What’s New?</h3> <p>Previously, the Computer Vision system displayed the same taxon photo for a species regardless of the observation. Now, it selects the most visually similar <b>Taxon Photo</b> for each suggestion.</p> <ul> <li>If you post a <a href="https://www.inaturalist.org/observations/168038179" rel="nofollow noopener">photo of a <strong>caterpillar</strong></a>, the suggestions will prioritize <strong>Taxon Photos of caterpillars</strong>.</li> <li>If you post a <a href="https://www.inaturalist.org/observations/261448680" rel="nofollow noopener">photo of an <strong>adult moth</strong></a>, the suggestions will prioritize <strong>Taxon Photos of adult moths</strong>.</li> </ul> <p>Before this update, the system would show the same default photo whether the observation was a caterpillar or an adult moth.</p> <a href="https://www.inaturalist.org/observations/168038179" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4294-original.png" width="100%"></a> <hr> <h3>How Does It Work?</h3> <p>The Computer Vision system now calculates <strong>visual similarity</strong> between the observation photo and the <strong>Taxon Photos</strong> for each suggestion.</p> <p>For example, if you observe a <strong>White-lined Sphinx Moth caterpillar</strong>, the system will compare your image to Taxon Photos and <strong>display the most similar one</strong>—in this case, a caterpillar rather than an adult moth.</p> <p>This improvement depends on having <strong>high-quality, diverse Taxon Photos</strong> that represent different life stages, sexes, and variations.</p> <hr> <h3>What Are Taxon Photos?</h3> <p>Taxon Photos are <strong>representative images</strong> displayed on each <a href="https://www.inaturalist.org/taxa/49348-Hyles-lineata" rel="nofollow noopener">Taxon Page</a>. Each taxon can have up to 12 taxon photos, and these are <strong>manually curated by the community</strong> to help with identification. You can add or edit Taxon Photos by clicking <strong>“Edit Photos” in the Curation</strong> menu on any Taxon Page.</p> <ul> <li>If you <strong>delete</strong> a Taxon Photo, the change will be reflected in suggestions <strong>immediately</strong>.</li> <li>If you <strong>add</strong> a new Taxon Photo, it may take <strong>up to 24 hours</strong> to appear in suggestions.</li> </ul> <p>To improve the system, Taxon Photos should include <strong>clear, high-quality images</strong> that represent the <strong>diversity</strong> of the taxon (e.g., different life stages, sexes, etc.). Here are some <a href="https://help.inaturalist.org/en/support/solutions/articles/151000184018-what-guidelines-should-i-follow-when-choosing-taxon-photos-" rel="nofollow noopener">taxon photo guidelines</a> you should follow.</p> <a href="https://www.inaturalist.org/taxa/49348-Hyles-lineata" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4293-original.png" width="100%"></a> <hr> <h3>How This Improves Coarser Suggestions</h3> <p>This update also helps clarify why the Computer Vision system suggests a <strong>higher-level taxon</strong> (e.g., genus) when species within that group <strong>look very different</strong>.</p> <p>For example:</p> <ul> <li>Suggestions of the beetle <strong><a href="https://www.inaturalist.org/taxa/253041-Asphaera" rel="nofollow noopener">Genus Asphaera</a></strong>, which includes highly variable species, will now display a <strong>genus-level Taxon Photo that visually resembles the <a href="https://www.inaturalist.org/observations/246684779" rel="nofollow noopener">observation</a></strong>—instead of the default Taxon Photo which may look very different. This works because all Taxon Photos of species below the genus are being considered.</li> </ul> <a href="https://www.inaturalist.org/observations/246684779" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4295-original.png" width="100%"></a> <hr> <h3>Change to Taxon Page Links</h3> <p>For <strong>species-level suggestions</strong>, clicking the <strong>“View”</strong> link will now open the <a href="https://www.inaturalist.org/taxa/49348-Hyles-lineata?photo_id=91759124" rel="nofollow noopener">Taxon Page with the most visually similar photo as the default</a>. However, this feature <strong>does not apply<strong> to coarser (non-species) suggestions.</strong></strong></p> <a href="https://www.inaturalist.org/taxa/49348-Hyles-lineata?photo_id=91759124" rel="nofollow noopener"><img src="https://static.inaturalist.org/wiki_page_attachments/4296-original.png" width="100%"></a> <hr> <h3>Next Steps</h3> <p>We’d love to hear your feedback on this improvement! We plan to roll out <strong>this feature to the iNaturalist mobile apps</strong> soon.</p> <p>Let us know what you think and how this affects your experience with Computer Vision Suggestions. </p>
