Long-Term Ecological Research (LTER)/AND007: Post-Logging Community Structure and Biomass

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

LTER/AND007 [Summary adapted from the LTER Core Data Set Catalog]:

Patterns of plant succession and biomass accumulation following
clearcut logging of an old-growth Douglas fir/western hemlock forest.
These data contain post-logging compositional and structural
information. A total of thirty-six 10 m x 15 m slope corrected plots
are located randomly within four habitat types in proportion to
habitat abundances. Data collected include: (1) visual estimates of
canopy cover for all herbaceous species, for ground surface categories
(i.e., bare ground, stone, litter, log, stump), and for mosses and
lichens within 45 Daubenmire plots (along three 15-m lines, 15 plots
per line); (2) line intercept cover for woody species along the same
three 15-m lines; (3) overstory tree cover in canopy and understory
classes within the entire 10 m x 15 m plot; and (4) a tally of
seedling and sapling trees in the 10 m x 15 m plot.

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.
