The place of research is the pasture territories of 11 administrative districts of Azerbaijan. The names of plant groups were carried out according to the dominant species, the abundance — according to the Drude scale. The age indices and indices of clover efficiency were studied. Biological and operational stocks of Trifolium L. species were determined in the Shirvan districts. Research results data: Trifolium medium — 8399.5 t; T. caucasicum — 12000 t; T. canescens — 47973 t; T. campestre— 4315 t; T. bonannii — 1119 t; T. tumens — 3164.4 t. The total biological stock of representatives of the Trifolium L. genus is 76.971 tons, of which 10%, i. e. 7.69 tons are operational reserves. This indicates that these species are valuable fodder plants.
