Long-Term Ecological Research (LTER)/AND013: Stream-Upland Wood Decay Experiment in the H.J. Andrews Forest

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

LTER/AND013 [Summary adapted from the LTER Core Data Set Catalog]:

This study examines and contrasts the decay of small logs in a stream
channel to those on an upland site. It also examines the movement of
small logs in a third- to fourth-order stream. Three species (Alnus
rubra, Pseudotsuga menziesii, Tsuga heterophylla) of logs, 20-30 cm
diameter, about 2.5 m long were added to a stream channel and adjacent
upland site. Thirty logs of each species were added to each site
(total n = 180). Periodically two logs of each species will be removed
from each site. The exterior dimensions of each log were measured,
logs were tagged, and position of each log in upland and stream sites
noted. Volume of heartwood, sapwood, inner bark, and outer bark on end
of each log were noted. Density of these substrates also determined
for each end of each log.

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.
