Abstract: The less disturbed sal forests had considerable number of sprouts/ ramets of leguminous shrubs. Except for Moghania bracteata and Desmodium triangulare, all other species were quite abundant in less disturbed sal forests. In general, Moghania, showed much greater sprouting than Desmodium at low disturbance and has maximum number of sprouts/ ramets in most of the observed stands. A few young genets and sprouts of the species also encountered in some safe pockets of highly disturbed sal forests. In general, species with greater sprouting efficiency had lesser percentage of seed germination. High stress (burning) severely affected the ramet proliferation but high disturbance (cutting) favoured the ramet production. In most of the cases, there was significant difference between low and high disturbance or heat stress in terms of number of ramets/ genets and inter- ramet distances along the age series of genets. In most of the cases t- values were differ significantly at < 0.05 P- level (d.f 8) between low/ high disturbance in terms of inter-ramet distance. Germination experiment was performed, under controlled conditions, with seeds of different eight species of Desmodium and Moghania. These eight species, common associates of sal forest, were germinated under constant darkness and constant light, at room temperatures. The germination process was monitored for 20 days. The germination in most of the species was better in the dark. Differences between the percentage of day- light and dark germinations were significant at < 0.05 P- level for all the species except M. chappar. The study on population status and regeneration pattern of these legumes can be used in a multiple of ways including high quality forage to wild animals, contributing rich organic nutrient for rehabilitation to degraded forests and also providing firewood to local people.
