Abstract. Composition and density of vegetation are important habitat quality indicators for reptiles. The goal of this note was to determine dominant plant species, optimal size and density in habitats of syntopic lizards in the Goravan Sands Sanctuary. The role of vegetation variables was considered in relation to differences in thermoregulation of syntopic Phrynocephalus persicus, Eremias pleskei, and Eremias strauchi. Microhabitats of P. persicus differed from that of E. pleskei and of E. strauchi by a relatively frequent encounter of the plant Achillea tenuifolia, which is considered as potential habitat quality indicator. Phrynocephalus persicus generally used microhabitats with sparser vegetation. It is supposed that the excessive growth of shading vegetation can have a more negative impact on P. persicus than on E. pleskei.

Abstract. – The Goravan Sands Sanctuary is an important Armenian wildlife conservation area. The objectives of my study were to assess habitat suitability for reptiles within the sanctuary by comparing species richness, total abundance and species diversity across 35 random quadrats. I present the mean abundance data of 5 reptiles: Phrynocephalus persicus, Eremais pleskei, Eremias strauchi, Lacerta strigata and Testudo graeca. Maps of the relatively uncommon lizard P. persicus reflect species richness patterns, whereas maps of the most abundant lizard E. pleskei more accurately reflect total reptile abundance and species diversity. About 71 % of the area of the patches is covered with regions of high and moderate species diversity – suitable for reptile inhabitation. Forteen percent of the area is covered with patches of low diversity. The moderate and highly suitable patches are recommended for intensive conservation management planning.
Key Words.—abundance; species diversity; habitat suitability; interpolation maps; reptiles; Armenia

Abstract. The Goravan Sands Sanctuary is the only “especially protected area” supporting the endangered Persian toad headed lizard. The objectives of the study were 1) to determine mean abundance of P. persicus in order to compare it with earlier published data and to develop grounds for further monitoring and 2) to delineate the spatial distribution of P. persicus within the Goravan Sands Sanctuary for conservation management planning. Visual encounter survey of 35 random quadrats (20x20 m) and on the way to the quadrats was implemented to determine the lizard’s abundance and distribution. The locations of specimens were registered with a GPS unit and mapped using Arc View GIS. Mean abundance of P. persicus in April-May, 2005 was Mean SE = 0.457 0.14; R – 0-4, n = 35, or nearly 11 specimens per hectare. It is nearly 4 times higher than in 1980s. However, no population increase is stated. 5 isolated population fragments were detected for P. persicus within 4 of 10 plots of sandy habitats. Sizes of population fragments (numbers of specimens) directly correlate with area (RSp =0.96; p<0.0001) and perimeter (RSp =0.91; p<0.0001) of sandy plots, and with edge effect values (RSp =-0.65; p<0.05). Plots of sands with area of about 2 ha do not support P. persicus. As conservation actions for larger habitat plots supporting all population fragments it is proposed to increase control and develop a public awareness system, to limit overgrazing, collection of lizards and sand mining For poorest population fragments it is suggested also to perform translocations and support the populations using bordering within natural vivaria.
