Bottom Line: Further, within the home range, closed canopy forests were used more during the day than at night.When elephants were in closed canopy forests they were most often near the forest edge vs. in the forest interior.Effective elephant conservation strategies in Sumatra need to focus on forest restoration of cleared areas and providing a forest matrix that includes various canopy types.

ABSTRACT
Increasingly, habitat fragmentation caused by agricultural and human development has forced Sumatran elephants into relatively small areas, but there is little information on how elephants use these areas and thus, how habitats can be managed to sustain elephants in the future. Using a Global Positioning System (GPS) collar and a land cover map developed from TM imagery, we identified the habitats used by a wild adult female elephant (Elephas maximus sumatranus) in the Seblat Elephant Conservation Center, Bengkulu Province, Sumatra during 2007-2008. The marked elephant (and presumably her 40-60 herd mates) used a home range that contained more than expected medium canopy and open canopy land cover. Further, within the home range, closed canopy forests were used more during the day than at night. When elephants were in closed canopy forests they were most often near the forest edge vs. in the forest interior. Effective elephant conservation strategies in Sumatra need to focus on forest restoration of cleared areas and providing a forest matrix that includes various canopy types.

animals-03-00670-f002: Proportions of elephant locations (total n = 355) and random locations (n = 1,000) in categories of the Euclidean distance (m) to the forest edge, depending on whether elephants were within or outside (“other”) closed canopy forest (shaded portion).

Mentions: Of 355 elephant locations within the 95% fixed kernel home range, 124 locations were within the closed canopy forest. When in the forest, elephants were located much more often near the edge and less often in the interior (Figure 2; Pearson’s chi-square: χ2 = 37.254, df = 4, P < 0.001). The median distance of elephant locations in the forest to the forest edge was 22 m (range = <1–452 m), and >80% of all locations within the forest were <50 m from the edge. In contrast, the median distance of random locations to the forest edge was 56 m (range = <1–695 m), and <50% of all random locations within the closed canopy forest were <50 m from the forest edge.
