1987 SCHNOES AND HUMPHREY: TERRESTRIAL COMMUNITIES IN FLORIDA 77

the spoil piles partly leveled, and the forest was more mesic than at Old Spoil Piles, with
more water oaks (background) mixed with the live oaks (foreground and left).


sampled patches of various habitats on H-4 and Kibler. We avoided the
non-pasture patches of habitat in sampling both plants and animals, but
these areas nonetheless affected the data for mobile animals.
 Though the two treatments were similar in amount of plant cover, the
grazed sites were consistently more diverse than the ungrazed sites (Figs.
3-5), resulting from selective cropping by grazers and non-selective har-
vest by mowing machines. The herbaceous cover was more abundant
than for any of the other treatments, as is expected in the absence of
competition from shrubs and trees. Herbaceous diversity, however, was
comparable to that on both consolidated clay settling areas and mature
unreclaimed pits and spoil piles.

 SMALL MAMMALS

 The results of sampling for small mammals are summarized in Tables
3-6. A total of nine species was sampled during the study.
 CONSOLIDATED CLAY SETTLING PONDS.-The clay areas supported
populations of cotton mice (Peromyscus gossypinus) and some rice rats
(Oryzomys palustris), cotton rats (Sigmodon hispidus), house mice (Mus
