. each species was retained as the number of individuals present. After determining the area <br />sampled, the densities were converted to number of individuals/100 ac (40 ha). <br />The small bird fauna of the rangeland habitat was censured using a 525 x 55 yard (480 x 50m) <br />belt transect (Map 2.04.11-1). All individuals present in the 5.96 acre (2.4 ha) belt were <br />recorded. The belt was traversed on three consecutive days and the three-day average of each <br />species was retained as the number present. The results were converted to number of <br />individuals/100 ac (40 ha). <br />The small bird censuses were conducted in the spring and fall. The spring censuses were <br />conducted on 27-29 May 1987. The fall censuses were conducted on 8-10 October 1987. All <br />censuring took place from 0.5 hours before sunrise to approximately 3-3.5 hours after sunrise. <br />The sequence in which each of the three habitats were censured during each three-day <br />sampling period was altered so that each habitat was sampled at different times during the 3.5 <br />to 4.0 hour daily sampling period. The weather during all censuring was clear and mild, with <br />some breezes during the spring. <br />The small bird density data was evaluated and compared using Whittaker's (1975) index of <br />• species diversity/richness (d) as follows: <br />d = s/log A where, <br />s = number of species (species richness) and <br />A = area sampled in square meters. <br />Reptiles and Amphibians. The occurrence and habitat affinities of reptiles and amphibians in <br />the New Horizon 2 study area was determined through incidental observations and specific <br />searches. Habitats within and adjacent to the study area were searched by perambulating <br />slowly through them turning rocks, logs, boards, etc. All reptile and amphibian observations <br />made during the course of this study were recorded in species accounts journals. <br />Fishes. No quantitative sampling of fishes or other aquatic vertebrates or invertebrates was <br />conducted in the study area. An ocular reconnaissance of ponds and ditches and interviews <br />with local residents were conducted to determine the fish species present in the study area. <br />Results and Discussion of the Fish and Wildlife Studies <br />Mammals. A list of the mammal species of confirmed or possible occurrence in the New <br />• Horizon 2 study area is presented, along with species habitat preference, in Table 2.04.11-2.
