At other sites in the central Cascades, recent research has addressed the ecology and dynamics of forest-meadow mosaics, changes in the aerial extent of meadow openings, the history of human use of meadows, the influence of volcanic deposits in forest and meadow soils of the western Cascades, and biogeochemical changes in soil properties across forest-meadow boundaries. |
