Quantifying soil
changes. Soils were
sampled
with
a steel-box sampler to a depth
of 30
cm. Profiles were separated into 4
horizons (O,
A, B1, B2), yielding quantitative
per-unit area estimates on soil mass. Samples were
initially collected in
1992 and again in 2003 after the Biscuit
Fire. Previously collected samples were
preserved in the LTEP samplebase
archive.
