DYNAMICS OF MICROBIOTIC SOIL CRUSTS IN BURNED SLASH PILES AT TURNBULL WILDLIFE REFUGE

The surfaces of many soils contain an array of organisms that collectively form a crust referred to as microbiotic soil crusts. These microbiotic crusts have been shown to be extremely sensitive to disturbances. I sampled burned slash piles (1, 4, and 6 years old) at Turnbull National Wildlife Refuge to determine changes in species composition, amount of total crust cover, and overall species abundance when compared to the pre-burned state. There was no significant difference in the amount of soil crust cover between the slash pile age classes. There was a difference, however, in the species composition. The difference in the species composition was also seen when comparing the slash piles to unburned plots adjacent to the slash piles.
