Watersheds
The vegetation has changed considerably since the BCEW Project was moth-balled in 1982. The fuels treatments for 2008 and beyond are shown in Table 1 below. Each watershed has a series of permanent plots that have been in place since the 1960s.

Water Quality
Samples for water quality analysis (suspended sediment and anions/cations) will be collected at the gauging flumes of each watershed during storm events that occur during summer Monsoon storms or winter snowpack runoff. Samples will be flow or time composited from ISCO Discrete Samplers depending on the flow characteristics for the period.
Vegetation Plots
Permanent vegetation plots were established in the mid 1960s (Table 1) and will be used for remeasurement of overstory vegetation, the understory, forest floor, and soils. |
