Quality of water for livestock in man-made impoundments in the northern High Plains

Publications Posted on: April 27, 2006
Twenty-seven water quality parameters were measured in coal surface mine impoundments, bentonite surface mine impoundments, and livestock ponds in the Northern High Plains. Most impoundments were safe for use as a source for livestock drinking water. Eight water quality parameters were different (a

Big game habitat use in southeastern Montana

Publications Posted on: April 27, 2006
The loss of suitable, high quality habitat is a major problem facing big game managers in the western United States. Agricultural, water, road and highway, housing, and recreational development have contributed to loss of natural big game habitat (Wallmo et al. 1976, Reed 1981). In the western United States, surface mining of minerals has great potential to adversely affect localized big game populations (Reed 1981).

Shrub and tree establishment on coal spoils in northern High Plains - USA

Publications Posted on: April 27, 2006
Trickle irrigation, during establishment, increased survival two fold for seven species of shrubs and trees planted on coal mine spoil in the semiarid area of northeastern Wyoming, USA.

Perennial forbs for wildlife habitat restoration on mined lands in the northern Great Plains

Publications Posted on: April 27, 2006
Research was designed to assess the establishment and growth potential of 30 perennial forbs by seeding and/or transplanting them on coal mine spoil materials over a 2-year period. Five species showed exceptional emergence and vigorous growth from direct seeding. Six species showed vigorous growth with the use of transplanted plants. Seeding resulted in successful stands of most forbs on coal mine spoil material.
