Threshold Categories
-
Prescribed fire is a common management practice for reducing excessive forest fuel loading to minimize the risk of wildfire. Prescribed fire may, however, adversely impact air and water quality by releasing nutrients from soils and vegetation upon combustion.

| 07/20/2017 4:14 PM | System | Objectives: This study assesses the carbon (C) and nitrogen (N) release as affected by fuel moisture during a prescribed fire near Incline Village, NV following mechanical thinning. The field component of this study involved a pre- and post-fire fuel inventory to estimate C and N losses under fall fuel moisture conditions. The laboratory component of the study further investigated effects of moisture on nutrient release and speciation. |

| 07/20/2017 4:13 PM | System | Findings: • Results from the field study showed that total fuel reductions were close to 90% and C and N losses closely followed patterns in fuel mass reductions. • Soil extractable ammonium (NH4+) increased immediately following fire, but no clear trends were observed for extractable nitrate (NO3-). • The laboratory combustion experiment showed that increasing fuel moisture caused increases in total particulates, including PM2.5 and C and N species, and gaseous ammonia (NH3) emissions for several fuel types. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional findings. |

| 07/20/2017 4:08 PM | System | Management Implications: • Conducting fuel treatments when fuel moisture is low will likely maximize fuel consumption while minimizing air quality impacts. However, dry burns not only increase fuel consumption, which will reduce C sequestration; they also favor conversion of fuels to CO2, which is an important greenhouse gas. • Although we did not specifically test this in our study, broadcast burns may lower C sequestration compared to pile burns, since broadcast burns can cause significant consumption of litter and duff compared to piles that have a much smaller footprint. As a result, while more C is being released under dry conditions, air quality impacts may be lower under these conditions suggesting a trade-off between short-term C sequestration and air quality management objectives. • In addition, high consumption of litter and duff may negatively impact short and long-term nutrient availability by removing a pool of easily mineralizable N. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional management implications. |
