The population status, structure, abundance and t rend of plains zebra ( Equus quagga ) were studied in Nechisar plains, Nechisar Nationa l Park, southern Ethiopia, using transects and silent detection methods. The populat ion of plains zebra in the area was estimated at 4500, with the population density of 1 6.6 km -2 . The average herd sizes of one- male harem and bachelor stallion herds were 10.8 an d 6.4, respectively. Adult males constituted 34.8%, adult females 41.5% and unsexed young 23.7%. Male:female ratio was 1.00:1.19. The age structure was 76.3% adult, 14.7% subadult, 5.2% juvenile and 3.8% foal. There was a rapid increase in their population duri ng 1970-1985 and then a decline over the period 1991-1995. An integrated action involving i mplementation of effective awareness programme among the local people and improving the socio-economic standards of the communities in the Nechisar plains is essential for the management of the plains zebra in Nechisar National Park.
