# Moss species list of the Andrews Experimental Forest, 1991

## Dataset

- **Database Code:** SA008

- **Title:** Moss species list of the Andrews Experimental Forest, 1991

- **Abstract:**

Understanding patterns of distribution and abundance for individual moss species is necessary for understanding ecosystem structure and function and for ensuring proper management. To augment understanding of the ecology of individual species, mosses were examined on the forest floor, on the upper surface of downed logs, and on tree bases in forest stands in the central western Cascades of Oregon on and near the H.J. Andrews Experimental Forest. This study quantifies local distribution patterns and substrate affinities to a greater extent than previous studies in the same geographic area (e.g., Pike et al. 1975, Hawk et al. 1978, Binkley and Graham 1981).
