Wooded Draws in Rangelands of the Northern Great Plains
Wooded draws and natural prairie woodlands occupy about 1.1 percent of the northern Great Plains. While the extent of wooded draws is extremely limited, their importance and value is much greater. These unique communities are important for wildlife and livestock habitats, soil stabilization, watershed maintenance, firewood, esthetics, and species diversity (Fig. 1). An estimate of their value h...
متن کاملBiological Control of Weeds in Great Plains Rangelands
Chemical control ofweeds has increased agricultural productivity, but complete reliance on chemicals has serious drawbacks. These include high cost per acre, decreasing effectiveness, negative effects on plant community diversity, and increased opportunities for environmental contamination. One alternative is biocontrol, the use ofbiologicalfactors that naturally limit weed populations. Long-te...
متن کاملManagement Implications of Global Change for Great Plains Rangelands
The Great Plains of North America encompass approximately 85 million ha (210 million acres) consisting of shortgrass, mixed-grass, and tallgrass prairie with about 60% of this area converted to crop agriculture and the remainder used primarily for livestock production. Large-scale gradients of precipitation (west to east, <30 to >100 cm; <12 to >40 inches) and mean annual temperature (north to ...
متن کاملInteractive Effects of Drought and Grazing on Northern Great Plains Rangelands
Drought is common in rangeland environments and an understanding of its impacts on the structure and function of rangeland ecosystems is paramount for developing effective management strategies. This research was the second of a series of studies investigating the impacts of varying seasonal droughts on northern Great Plains rangelands. Research was conducted on native rangeland during the 1998...
متن کاملForum Effects of Grazing Pressure on Efficiency of Grazing on North American Great Plains Rangelands
Comparisons of stocking rates across sites can be facilitated by calculating grazing pressure. We used peak standing crop and stocking rates from six studies in the North American Great Plains (Cheyenne, Wyoming; Cottonwood, South Dakota; Hays, Kansas; Nunn, Colorado; Streeter, North Dakota; and Woodward, Oklahoma) to calculate a grazing pressure index and develop relationships for harvest effi...
