Abstract:

Plant communities were classified and relationships between the environment and vegetation were examined in old-growth forests in a small watershed in the Hoh River valley of western Olympic National Park; Hoh Laket Watershed. Detrended correspondence analysis (DECORANA) was used to ordinate the data. Elevation and slope were the primary environmental gradients. Two-way indicator species analysis (TWINSPAN) was used to classify the data. Three community types were classified in the closed canopy forest at Hoh Lake (Abies amabilis-Tsuga mertensiana/Vaccinium membranaceum, Abies amabilis-Tsuga mertensiana/Erythronium monatum, and Abies amabilis/Rhododendron albiflorum). The vegetation community at Hoh Lake was generally homogeneous (5-11 understory species/0.1 ha plot).Tree density was greatest in disturbed communities caused by steep, active creep slopes at Hoh Lake.

Purpose:

The objectives of this study were to describe and classify the vegetation in a high (Hoh Lake watershed) elevation old-growth forested watershed in the Hoh River Valley, Washington and examine relationships between the environment and plant communities.

Methodology_Description:

At Hoh Lake 5 circular permanent sample plots (1000 m2) were established after plant communities were delineated on aerial photographs, and verified with ground-reconnaissance of the closed-canopy forest in the basin. . Nested circular plots were used within the larger plots. Seedling presence by species was determined in four 20 m2 subplots; in 50 m2 subplots percent cover of herbs, shrubs, moss lichen, bare soil, litter and rocks (>8 cm) were recorded. Trees were measured and coded in 500 m2 (250 m2 in reconnaissance plots) and large trees (>50 cm dbh) and all snags were measured within the 1000 m2 plots (500 m2 reconnaissance plots). Percent slope, aspect, elevation, topographic shape, and slope position was determined for each plot at plot center.

Process_Step:

Process_Description:

Detrended correspondence analysis (DCA), an ordination technique, was used to analyze the data. Species and sample ordinations were calculated by DECORANA (Hill 1979a). The samples scores were weighted means of the species scores within each sample. Data were classified using the two-way indicator analysis program TWINSPAN (Hill 1979b).
