Production and supply of muga seed in Assam, has been suffering due to erratic abiotic factors, affecting the commercial crops and finally leading to low muga silk production. The narrow ecological distribution of host plants has also been a reason for the production being confined to Assam and Meghalaya. Recent attempt to introduce it in Bastar plateau yielded encouraging results. Details.

We used a vulnerability scoring system to assess the vulnerability of 117 vertebrate species that occur in the Middle Rio Grande Bosque (MRGB) to expected climate change. The purpose of this project was to guide wildlife managers on options and considerations for climate change adaptation. The 117 species occur regularly in the MRGB during the breeding season, winter, or year-round. In general, future climate scenarios predict warmer temperatures with an altered precipitation regime that will likely lead to reduced water levels in the MRGB. This assessment points to several key issues relating to future habitat changes and individual species physiology that are expected to affect species survival under climate change. Decreased availability of mesic sites is expected to directly impact many amphibian and reptile populations and is expected to have indirect affects for birds and mammals primarily through changes in habitat availability. We predicted that phenological changes will negatively impact many species within all taxonomic groups through altered timing of weather events and river flow. Riparian-dependent species received some of the highest vulnerability scores. Species already at the southern limit of their distributional range were also predicted to be more likely to be vulnerable to climate change. The assessment also identified important data gaps. Management for species conservation under future climate conditions will require increased research and monitoring, greater integration of landscape-scale approaches, consideration of future land-use scenarios, and increased understanding of the consequences of species' interactions. We review the specific implications of climate change for wildlife in the MRGB in order to identify intervention points and approaches that may achieve management goals.

Sagebrush ecosystems are among the largest and most threatened ecosystems in North America. Greater sage-grouse has served as the bellwether for species conservation in these ecosystems and has been considered for listing under the Endangered Species Act eight times. In September 2015, the decision was made not to list greater sage-grouse, but to reevaluate its status in 5 years. Concerns over sage-grouse and associated habitats have set in motion sweeping Federal and State land management plan changes and proactive science- based conservation actions to address threats within the realm of management control. For nearly a century, the Forest Service (FS), U.S. Department of Agriculture (USDA), has studied sagebrush ecosystems and for decades has focused on sage-grouse biology and habitat requirements. Our team of FS scientists and managers prepared this assessment to summarize FS strengths, capabilities, partners, past and current research, and potential future high-priority research areas for conservation and restoration of sagebrush ecosystems and sage-grouse. We identified research and science-based management needs of the National Forest System where lands are important for breeding and brood-rearing habitats for sage-grouse. We recommend expanded research and science delivery by FS scientists. This work will help meet continuing widespread concerns and calls for science-based conservation to mitigate threats to sagebrush ecosystems, conserve populations of sage-grouse and other sagebrush-obligate species, and restore sagebrush ecosystems throughout the western United States. © 2016, USDA Forest Service.
