The present study aims to address this information gap by providing current population estimates and information on the diet of Starck’s hare in BMNP. This information will form the base-line data relevant to further studies and conservation of the species and the Ethiopian wolf. Study Area and Methods The study area This study was conducted at the Bale Mountains National Park (BMNP). The typical Afroalpine habitats in BMNP; namely Sanetti Plateau (3800-4050 m a.s.l.), Web Valley (3450-3550 m a.s.l.) and Tullu Deemtu (4000-4377 m a.s.l.) formed the main study areas. Details are provided in Sillero- Zubiri (1994). Distance sampling methods To estimate density we used distance sampling (Buckland et al. 1993). Ten 4 km long parallel transects were systematically placed over 40 km2 on each of the three study areas at an interval of 1 km. The first transect was randomly taken, then the others were placed parallel at a distance of 1 km. Transects were traversed on foot, each time a hare was seen the numbers of animals seen, the sighting distance, bearing, habitat type, and wind level were recorded. The survey period was carried out at dusk and dawn. For data analysis, Distance version Beta 4.1 was used. The default detection function, half normal with a cosine adjustment, was used. SPSS version 13.1 software was used. Data for the availability of vegetation were obtained from 44 sample sites using line intercept method. At each sample site, coverage and frequency of individual plants were recorded and noted for each species touching the 15 m line intercept (Floyd and Anderson 1987; Sutherland 1996; Cummings and Smith 2001). Samples were systematically taken every 200 m interval from along transects randomly laid at different directions in the study area. Plant specimens were collected, pressed, dried and identified in the National Herbarium of Addis Ababa University. To find the mean percentage coverage of each species (MPCSp), the following formula was used: TCSp MPCSp = × 100 L Where, TCSp = Total cover of the species, L= Length of line To find the mean percentage vegetation coverage of the site (MPCS), MPCS TCS = × 100 L Where, TCS = Total cover of the site, L = Length of line <strong>Walia</strong>-<strong>Special</strong> <strong>Edition</strong> on the Bale Mountains 54
To identify the types and proportion of plant species used by L. starcki, a combination of faecal analysis and direct observation was used. Fresh pellets of Starck’s hare were collected from sites of different vegetation types during both seasons. In each season, two pellets were collected from 25 independent dropping groups at a minimum of 200 m apart. Samples were preserved in 70% ethanol and taken to the Department of Biology, Addis Ababa University, for further analysis where they were broken up, homogenized and then washed independently with distilled water to remove fine particles for proper identification and air dried. Two slides were prepared for each sample (mixing thoroughly) and observed under the microscope to identify the plant fragments. All fragments found on the slides were identified as monocotyledon, dicotyledon, or unidentified. Relative occurrence was determined by dividing the number of microscopic views in which a given species occurred by the total number of views x 100 (Uresk 1978; Katona and Altbacker 2002). In addition, direct observation was also used to identify different species of grasses consumed by Starck’s hare. Four different types of habitats, where hares usually fed, were chosen for observation from a hide. Using 8 x 42 binoculars, species of plant eaten were examined for 120 hours (68 and 52 hrs during wet and dry seasons, respectively). The plant species on the habitat was directly observed, before and after, to see the plant eaten by looking at bitten stems and leaves. Results A total of 389 and 267 Starck’s hares were recorded during wet and dry seasons, respectively. The difference was statistically significant (X2 = 22.69, df =1, P< 0.001). The highest number was 185 during the wet season in the Sanetti Plateau and the lowest was 61 during the dry season in Web Valley (Table 1). Once a hare was seen on a transect, others were often observed. The number of sightings refers the number of times a first hare was seen and individuals is the total number seen. Table 1.

The highest density was obtained from Sanetti during the wet season (25.40/km 2 ) and the lowest at Web Valley during the dry season (8.51/ km 2 ). <strong>Walia</strong>-<strong>Special</strong> <strong>Edition</strong> on the Bale Mountains 55
