Population Viability Analysis for the Przewalski's Gazelle

Population Viability Analysis for the Przewalski's Gazelle The Przewalski's gazelle, Procapra przewalskii, is now isolated in four local populations on the east and northwest shores of Qinghai Lake. We have been being conducting field surveys in the Qinghai Lake region since 1994. Based on the information we gathered from those surveys, we carried out a Population Viability Analysis (PVA) on the Przewalski's gazelle. We discovered that the Przewalski's gazelle would be extinct within 200 years if no management measures were taken. Since the local population size of the gazelle is small, the most effective measures are to control the wolf density and to reduce the impact of climatic catastrophes. In order to increase the population of the gazelle, we should also take measures to increase primary production of the grassland, to establish a habitat corridor, and to increase the rate of migration of individuals among different local populations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

The Przewalski's gazelle, Procapra przewalskii, is now isolated in four local populations on the east and northwest shores of Qinghai Lake. We have been being conducting field surveys in the Qinghai Lake region since 1994. Based on the information we gathered from those surveys, we carried out a Population Viability Analysis (PVA) on the Przewalski's gazelle. We discovered that the Przewalski's gazelle would be extinct within 200 years if no management measures were taken. Since the local population size of the gazelle is small, the most effective measures are to control the wolf density and to reduce the impact of climatic catastrophes. In order to increase the population of the gazelle, we should also take measures to increase primary production of the grassland, to establish a habitat corridor, and to increase the rate of migration of individuals among different local populations.
