Forest history and meadow invasion at the Rigdon Meadows Archaeological Site, western Cascades, Oregon

Auteur :
HADLEY, K.S.

Description :
Combining stand structure and fire-scar data with historical records, aerial photographs, and soil descriptions, the forest history of the Rigdon Meadows Archaeological Site in the western Cascades of Oregon is reconstructed. The A. is specifically interested in how forest structure and disturbance regimes differed during prehistoric, settlement, and modern periods. Results indicate that forest composition and meadow persistence are determined primarily by disturbance, soil properties, and topography. Dramatic changes in forest structure beginning in the mid-1800s resulted from fire, grazing, road building, clearing, and selective logging.
