The impacts of cable snare hunting on wildlife poulations in the forests of the Central African Republic

Article Abstract:

Cable snare hunting, the dominant hunting method in central African forests, does not appear to be sustainable for three species of duiker that are among the most commonly captured. The duiker species Cephalophus callipygus, C. dorsalis, and C. monticola and the brush-tailed porcupine (Atherurus africanus) account for 75% of the animals captured in a study of 17 snare hunters. Twenty-seven percent of captures are lost to scavengers or decomposition, while more than one-third of the snared animals break away and escape although injured. Two percent of the animals captured are from protected species.

Alternatives to Robinson and Redford's method of assessing overharvest from incomplete demographic data

Article Abstract:

Overharvesting can be detected with minimal demographic data by a simpler method than the one formulated by Robinson and Redford. The proposed method assumes constant survival rates of adults, while empirical data on prereproductive and adult survival can be used if available. The proposed method gives closer estimates than those obtained by Robinson and Redford when compared with results from complete mammalian life tables. Approximate growth rates from incomplete information should be used with caution when concluding that sustainable harvest rates have been achieved.

Viability and conservation of an exploited sage grouse population

Article Abstract:

Studies of sage grouse populations in North Park, CO, were conducted to evaluate the impact of hunting and habitat degradation on the population. Evidence from experiments showed the populations were affected most by habitat manipulation. Moderate levels of canopy cover of sagebrush are recommended. If population viability is conserved through habitat manipulation, grouse hunting may continue without adverse effects.
