Abstract:
Factors that limit successful revegetation of a subalpine
site were studied through a combination of soil assays, greenhouse
studies, and field manipulations. Campsite soils had higher available
nitrogen, lower microbial community diversity, and lower seed
bank density than undisturbed soils. In the greenhouse, there was
no significant difference in plant growth on disturbed versus.
undisturbed soils. In the field, seedling establishment patterns did
not vary between experimental plots with five different soil treatments
(ranging from a control to a compost and inoculum amendment).
Addition of seeds and transplants increased seedling density,
but not growth. Microclimatic variation may be the overriding
limiting factor at this site.
