The Colorado Division of Wildlife (CDOW) proposes to conduct a study of the Parachute/Piceance/Roan (PPR) population of greater sage-grouse during 2007 and 2008. The PPR is one of several small, spatially fragmented populations of sage-grouse in Colorado. The CDOW is interested in working with energy companies and other land owners and managers in the PPR area to sustain the PPR grouse population and plan for future management actions. The objectives of the study are to obtain current, baseline information on the genetic characteristics; measures of reproduction and survival rates; and patterns of habitat use and seasonal movements of sage-grouse in this population.
This issue brief provides a brief overview of unmanned aircraft systems (UAS), related federal and state regulations, and current uses and restrictions in Colorado.
A PEL Study to provide an understanding of the existing conditions at the Interstate 70 (I-70) and Kipling Street (State Highway 391) interchange while considering future surrounding development and community plans. This Environmental Scan Report identifies environmental resources and environmentally sensitive areas; this is mostly comprised of readily available data and field survey information. The purpose of this scan report is to identify resources early in the planning process to avoid fatal flaws and to consider sensitive carry them through project development, design and construction.
Our drinking water supplies, fishing and recreational waters are fouled by uncontrolled pollution when rainwater and snowmelt wash over city streets, parking lots, and suburban lawns and pick up toxic chemicals, disease-causing organisms (from pet waste), and dirt and trash. This problem is called urban stormwater pollution. Recent studies have found that urban stormwater rivals and in some cases exceeds sewage plants and large factories as a source of damaging pollutants. Two hundred years of unregulated, unmanaged urban stormwater have contributed to many severe public health problems and expensive natural resource losses in the United States.
Living snow fences (LSF) are designed plantings of trees and/or shrubs and native grasses along highways, roads and ditches that create a vegetative buffer that traps and controls blowing and drifting snow. These strategically placed fences have been shown to be cost effective in reducing highway maintenance associated with blowing and drifting snow conditions.
