Salix brachycarpa

This contention was tested in soils beneath high elevation willows (Salix brachycarpa) in the Colorado Rockies (3500 m asl) (Schmidt et al., 2000), whose bark accumulates 280 pg g of salicylate in average. As a control, Kobresia myosuroides that yields much less salicylate was used. Both tree species were dominant in the area. Differences in salicylate-mineralizing microbes from under both species were very significant (<1 pg biomass C g" soil in the control vs 4.6 -10 pg biomass C g" soil under the Salix trees). Therefore, soil microbe populations may depend strongly on secondary plant chemistry, and as a result plant community structure may govern soil performance in these elevated habitats and others as well.
