Various methods may be used to accomplish this initially and to maintain this condition. Ideally, the firebreak will be constructed and maintained according to the established practices of sustainable <a href="/wiki/Forestry" title="Forestry">forestry</a> and <a href="/wiki/Fire_protection_engineering" title="Fire protection engineering">fire protection engineering</a>, also known as best management practices (BMP). The general goals are to maximize the effectiveness of the firebreak at slowing the spread of wildfire, and, by using firebreaks of sufficient size and density, to reduce the ultimate size of wildfires. Additional goals are to maintain the <a href="/wiki/Ecology" title="Ecology">ecology</a> of the forest and to reduce the impact of wildfires on <a href="/wiki/Air_pollution" title="Air pollution">air pollution</a> and the global <a href="/wiki/Climate" title="Climate">climate</a>, and to balance the <a href="/wiki/Cost-benefit_analysis" class="mw-redirect" title="Cost-benefit analysis">costs and benefits</a> of the various projects.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

In many cases, it may be useful for firebreak upkeep to be maintained along with the harvesting of forestry products, such as <a href="/wiki/Lumber" title="Lumber">lumber</a> and <a href="/wiki/Biomass" title="Biomass">biomass</a> fuel, since the objectives are fundamentally related, in that the basic goals are to remove material from the forest. Furthermore, if done properly, the value of these products can significantly offset the cost of maintaining the firebreak. In addition, these commercial industries and <a href="/wiki/Small_business" title="Small business">small businesses</a> are helped by a reduction in the property damages caused by wildfires, and reduced <a href="/wiki/Return_on_investment" title="Return on investment">risk of investment</a>.
