Restoration of Insular Ecosystems: Control of Feral Goats on Aldabra Atoll, Republic of Seychelles 总被引:1,自引:0,他引:1
The control of feral goats (Capra hircus) was studied on Aldabra Atoll, Republic of Seychelles, from October 1993 to May 1994 and November 1994 to May 1995. A total
of 832 goats was killed on Aldabra using the Judas goat technique and traditional hunting methods. Twenty-eight goats equipped
with radio transmitters (Judas goats) were used to locate and kill other feral goats. The remnant goat populations on Ile
Picard (n=13) and Ile Malabar (n=19) were eradicated during the first season. On Grande Terre, a total of 798 (374 M : 424 F) goats were killed. Mean group
size was 3.2 with a range of 1–20. Judas goat hunting became increasingly important over time with 18.0% (n=85) of goats killed in the presence of Judas goats in the first season compared to 42.3% (n=126) of goats killed during the second season. The overall kill rate for the project was almost 2 times greater for Judas
goat hunting (0.61 goats killed/h) than traditional hunting (0.32 goats killed/h). The home range size of each Judas goat
and the number of goats killed in association with it was significantly related. Using the Leslie–Davis removal method of
population estimation, 84 goats were estimated to remain on all of Grande Terre at the end of thebreak project.
