Long-Term Ecological Research (LTER)/AND011: H.J. Andrews Forest Watershed 1 and 3 Plant Succession Data 1962-1977

LTER - Long-Term Ecological Research Program/H.J. Andrews Forest (AND)

LTER/AND011 [Summary adapted from the LTER Core Data Set Catalog]:

This study documents patterns of plant succession after clearcut
logging and slash burning on two experimental watersheds. See data set
TP73 for post-1977 data. Both watersheds were dominated by old-growth
and mature Douglas fir/western hemlock forest prior to logging. Plots
were classified into one of six pre-disturbance plant communities, one
of nine soil series, and one of four soil disturbance classes
resulting from logging and burning. A total of 131 plots are evenly
spaced on six transects on Watershed 1 (entire 100 ha logged); 61
plots lie on 10 transects within three cutting units on watershed 3
(total of 25 ha logged). Canopy cover and frequency of herbaceous
taxa, ground surface categories (i.e., bare ground, stone, litter,
log, stump), and moss and lichen obtained from nine 0.33 m x 0.33 m
subplots within one quarter of a 2 m x 2 m plot; cover of woody
species estimated form entire 2 m x 2 m plot. A subset of plots have
had photos taken since 1963. Samples were taken annualy from
1962-1973 and every 2 years from 1974-1977.

The Andrews Forest is in the western Cascade Range of Oregon in the
15,800-acre drainage basin of the Lookout Creek, a tributary of Blue
River and the McKenzie River. The area elevation ranges from 1350
feet to 5340 feet and contains excellent examples of Pacific Northwest
conifer forests, wildlife, and ecosystems.
