Subsistence Bhutanese ranchers spread across various agro-biological zones keep up huge species and varietal variety of various harvests in their homestead. In any case, no examinations have been embraced at this point to evaluate why ranchers ration and keep up huge agro-biodiversity, the degree of agro-environmental wealth, species extravagance, assessed loss of customary assortments and dangers to the deficiency of on-ranch agro-biodiversity. Data on the quantity of assortments developed by the ranchers for six significant staple harvests were gathered from nine locale and twenty sub-regions spread across six distinctive agro-natural zones of the nation to comprehend ranchers explanations behind keeping up on-ranch crop variety, gauge agro-environmental wealth, species extravagance and the general loss of customary assortments, to realize the famers' degree of mindfulness on environmental change and the various dangers to trim variety. The outcomes from this examination demonstrated that a mind-boggling 93% of the respondents oversee and use agro-bio diversification for family food security and occupation. The normal agro-environmental extravagance went from 1.17 to 2.26 while the normal species lavishness went from 0.50 to 2.66. The normal agro-biological wealth shows a huge agro-environmental heterogeneity as far as the various types of staple yields developed.
