KEYWORDS:

Disturbance, community structure, geomorphology, debris flows, landslides, community composition, succession, disturbance

PURPOSE:

To examine vegetation development on landslides by sampling a chronosequence of landslides 6-28 years old; to determine species that successfully revegetate landslides, and determine whether species composition changes with landslide age.

METHODS:

Experimental Design - GV002 :

Description: Twenty 4.5 mi-acre were plots established in a grid pattern across each lankslide surface (fewer if landslide too small to fit 20 plots). Plots are circular.

Field Methods - GV002 :

Description: Ocular estimate of each species cover for whole plot.

SITE DESCRIPTION:

All plots on landslide scars and deposits, on all aspects, slopes 50-173%, elevation 1500-3600 ft, on clearcut sites, undisturbed forest sites, roadcuts and roadfills. Landslides occured between 1953 and 1975.

TAXONOMIC SYSTEM:

None

GEOGRAPHIC EXTENT:

Upper Blue River drainage including Tidbits, Ore, Mona, Mann, and Wolf Creeks. Western Oregon Cascades.
