Goitered Gazelle, Gazella subgutturosa: its habitat preference and conservation needs in Miandasht Wildlife Refuge, north-eastern Iran (Mammalia: Artiodactyla)

Abstract

The present paper discusses the habitat preference of the Goitered Gazelle (Gazella subgutturosa Güldenstädt, 1780) using a combination of Geographical Information System (GIS) and statistical analysis of its spatial distribution in Miandasht Wildlife Refuge, north-eastern Iran. The critical habitat for gazelles in the Wildlife Refuge is composed of hilly terrain near flat plains where they prefer to feed; the nearby hilly escape terrain decreases their susceptibility to poachers. However, the gazelles’ “catchability” increases among hilly areas where their limited eyesight increases the chances for cheetahs to approach them. However, given the low density of the cheetahs, it seems that predators do not greatly affect gazelle spatial distribution in Miandasht. Marginal cultivated lands attract the gazelles from early summer until early winter which increases the frequency of gazelle sightings in tamarisk plains leading to farmlands. Poaching records indicate that a majority of gazelles have been taken on the open plains, usually en route to cultivated lands where suitable escape terrain is not available. The area is well-known for its large gazelle population in the past as well as its small cheetah population at present; therefore, immediate law enforcement is necessary to control the present decline in gazelle numbers, particularly in marginal habitats.
