Ecological efficiency is the product of the efficiencies with which organisms exploit their food resources and convert them into biomass. (E.Ricklefs & L.Miller , 1999). This survey was accomplishing during for seven month on the 20000 ha of the south part of the Sabzevar region. The lizards captured on 4 one-ha plots (I-II-III-IV) that were chosen to represent two kind of vegetation (include of shrubs and bushes). Plots I, II placed at shrubs vegetation (Tamarix hispida and Haloxilon aphyllum) and plots III, IV placed at bushes vegetation (Peganum harmala and Cousinia sp). Lizards were sampled by 2 methods. The first method consist of padding, repeated search of areas during 2 days (on morning, noon and after noon and night). Nearly all encountered lizards were captured by noosing or by hand. The second sampling method was accomplished with pit-fall trapping. Twenty pitfall traps were established in each plot. All traps were plastic buckets (20 cm diameter and 18 cm length). Traps were placed at random-systematic within a plot, buried in the ground, and leveled with the soil surface. Traps were checked each 3 days. Finally each captured lizard was weighed and data analyzed with ANOVA method (by SPSS software). Outcome of analyze demonstrator that mean of lizard biomass in each of plots I,II is different with plots III,IV, {I III,IV & II III , IV} , in addition , it is true for the sum mean of I,II and III,IV, {I,II & III,IV}.
