Northern bobwhites select for native grasses on working grazing land
The Journal of Wildlife Management, EarlyView.Northern bobwhites in eastern Kentucky selected for native warm‐season grasses at multiple spatial scales in an environment dominated by exotic cool‐season grass cattle forage. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands ...

The Journal of Wildlife Management, EarlyView.We modeled prairie grouse abundance across Nebraska and projected future woody encroachment to estimate population losses. By combining predicted gains from woody treatments with avoided losses and treatment costs, we mapped return on investment to identify areas for woody treatments that maximize benefits to greater prairie‐chickens and sharp‐tailed ...

Rangeland Management Series: Annual Rangeland Forage Quality [PDF]
, 2001 Author(s): George, Melvin; Nader, Glenn; McDougald, Neil; Connor, Mike; Frost, Bill | Abstract: Livestock on California's foothill rangelands get much of their nutrition from rangeland forage plants. Year-to-year variations in environmental conditions determine the nutrient content of this forage.

Land Degradation &Development, EarlyView.ABSTRACT Although several environmental challenges exist globally, land degradation is the greatest threat and risk factor wedging human livelihoods. Despite widespread awareness of climate change, little empirical evidence exists on land degradation and its impacts on livelihoods in semi‐arid agroecological systems.

Accounting for the World’s Rangelands
Rangelands, 2007 How much rangeland do we have? Globally we do not know. I suspect the same can be said nationally. If we do not know what we have, how can we monitor it and develop a strategy for management? Existing statistics and definitions for rangelands or grasslands vary widely.

Estimating Land Degradation Level Using Remote Sensing Data and Fuzzy AHP Technique
Land Degradation &Development, EarlyView.ABSTRACT Land degradation is a critical global environmental concern that significantly impacts ecosystem services, agricultural productivity, weather patterns, human livelihoods and overall well‐being. Prompt and precise assessments of land degradation status are crucial for environmental governance and sustainable development. Remote sensing data can
