of gazelle is endangered is because of mechanized hunting; hunters using vehicles increase its decline. Civil unrest, for instance in Sudan, also negatively affects the life of the dama gazelle. Since the gazelle is already having a hard time surviving, these conditions have made its habitat unsuitable. A potential threat the dama gazelle faces is tourism. Tourists want to take pictures of this endangered species, and in doing so, may be perceived as a threat, especially during the hot season. Gazelles will run away from perceived danger, and in the hot season may overheat and die of stress. Conservation efforts Relatively few actions have been taken in the conservation of the dama gazelle. The few measures that have been taken are reserves so the animal can live in a peaceful environment and captive breeding to help rebuild the populations. A reserve for mhorr gazelles was set up in 1971 to help avoid extinction. This reserve, Parque de Rescate de la Fauna Sahariana (Rescue Park for Saharan Fauna) of the Estación Experimental de Zonas Áridas (Experimental Station of Arid Zones), is in Spain. The reserve has been a success and is still around today. Another reserve for the mhorr subspecies was set up in Chad, the Ouadi Rime-Ouadi Achime Faunal Reserve. This reserve was effective from 1978–1987, but due to civil war, it was abandoned. Captive breeding is a very popular way to help an endangered species repopulate. The species reproduces in captivity, but the small founder population potentially presents a problem and may result in inbreeding. The primary focus of European EAZA zoos is the mhorr gazelle (N. d. mhorr), while the primary focus of North American AZA zoos is the addra gazelle (N. d. ruficollis). Mhorr gazelles are also kept in North African facilities and both subspecies are kept in the Middle East. These are maintained as part of the European Endangered Species Programme and Species Survival Plan. The studbooks include 293 mhorr (2014) and 168 addra gazelles (2012). One participant in the addra gazelle plan, White Oak Conservation in Yulee, Florida, has bred the gazelles since 1983, resulting in nearly 300 births. Several hundred additional animals that are not managed as part of the studbooks are kept privately, especially in Texas. Small population size and inbreeding are a serious concern in this population due to the increased parasite load and reduced reproductive viability. Few substantial in situ conservation
