The survey covered 527 forms (species and subspecies). The total captive population of artiodactyla is over 34,600 individuals ranging in size from dik-dik to giraffe and ranging in habitat from aquatic pygmy hippos to desert antelope. Table 1 provides a summary of the captive population by families. Of the 527 forms, 154 are listed in either the IUCN Red Data Book, or CITES, or the USDI endangered species list at some level, and 115 of those are in captivity. Table 2 provides reviews of the threatened/protected captive population and the total captive population based on the physical size of the species, and on those species requiring "mountain" habitat. It has been compiled for use in reviewing current and potential captive habitat for future breeding programs. The final portion of this report, Table 3, is a list of 126 species and/or subspecies which are listed in the Red Data Book as endangered, or are CITES 1, or are considered at risk by the Antelope Specialist Group of the IUCN. These include 2 hogs, 1 peccary, 2 muntjac, 31 deer, 13 wild cattle, 6 duikers, 44 antelope and gazelles, and 25 goats, goat-antelope or sheep. 2 Of the 126 forms on the list, only 13 have captive populations that are greater than 100: Ce!Vus duvauceli Ce!Vus eldi thamin Ce!Vus nippon taiquanus Bos guarus Kobus leche leche Oryx dammah Oryx leucoryx Addax nasomaculatus Gazella dama Gazella dama mhorr Gazella dama ruficollis Gazella leptoceros Hemitraqus jayakari Following the name of each species is its status in the wild and then its current captive population as reported by ISIS, IZY and, if existing, the international studbook. Also included are IZY population figures for 1976 which can be used as a quick, rough reference on whether the captive population is increasing, decreasing, etc. The information given on recorded births and captive populations by continent might also help provide a more complete picture of each species' captive status. Under the heading "Some Captive Locations" can be found the locations of some of the larger captive collections, the Texas ranch figures (TXRAN), and current AZDANZ populations (AZD). The last section of this report is a review of status in captivity of all forms of artiodactyla. Many individuals provided information for this survey, among them Nate Flesness, Tom Foose, Jim Dolan, Larry Killmar, Peter Olney, Bruce Read and Paul Garland. 3 TABLE 1 STATUS HI CAPTIVITY SUI'IIIARY QF ALL ARTIODACTYLS COI'If'!Oii NAI'IE TOTAl NO.

Of these 527 taxa, 154 are listed in the IUCN Red Data Book, CITES or the USDI endangered species list. One hundred and twenty-six of those are either Red Data Book Endangered or CITES 1 or have been identified by the IUCN Antelope Specialist Group as being at risk or in need of captive propagation. These include 2 hogs, 1 peccary, 2 muntjac, 31 deer, 13 wild cattle, 6 duikers, 44 antelopes and gazelles, and 25 goats, goat-antelope or sheep. Of the 126 taxa that are seriously threatened, about half ( 69) have some known captive population and 19 of these are part of a captive program (studbook, SSP, EEP, etc). Only 13 taxa have captive populations
