Dirt goes downhill: Are we making better post-wildfire erosion control treatment decisions?

Events Posted on: December 07, 2020
In this webinar, Pete Robichaud discussed soil erosion prediction tools to allow for better post-fire land management decision-making.

Erosional processes on forest roads and flow duration characteristics of the Horse Creek streams

Publications Posted on: July 08, 2020
Present concern for the potential impacts land use activities can have on the water resource has prompted an increased interest in evaluating the effects of forest management practices on Water yield and quality.

Effects of forest roads on stream sediment

Publications Posted on: July 08, 2020
This paper discusses some on-site erosion and stream sedimentation consequences of forest road construction in small watersheds in northern Idaho. Pioneering and culvert installation increase sediment fluxes in the streams, just below the road, 100 to 10,000 times the normal daily flux for short periods of time.

After Fire: Toolkit for the Southwest

Tools Posted on: April 23, 2020
Wildfires are an important natural disturbance in southwestern ecosystems, but burn areas may be subject to hazardous post-fire erosion and flooding. There are numerous existing science and management tools for mitigating these hazards, but they are not always accessible to the communities and private landowners who need them.

Some relationships of plant cover to run-off, erosion, and infiltration on granitic soils

Publications Posted on: February 19, 2020
The fact that plant cover influences run-off, erosion, and infiltration has been firmly established by past research. Only under a few special conditions, however, has the degree of this influence been determined quantitatively. The study reported in this article was undertaken to secure a usable measure of this quantitative relationship, and to provide data for watershed management in the mountains of Colorado.

Artificial reseeding on abandoned farm lands and other eroding areas in Manitou Park, Colorado

To determine the best species and methods to use for reseeding denuded lands as an erosion control measure.

Notes from the Manitou Experimental Forest

Publications Posted on: February 19, 2020
The Manitou Experimental Forest is a branch of the Rocky Mountain Forest and Range Experiment Station. It is in the Pike National Forest, 28 miles north and west of Colorado Springs. This experimental area of 26 square miles was established in 1936 to study problems of watershed management, grazing, and other kinds of land use in the Front Range of the Colorado Rockies.

Relation of plant cover to infiltration and erosion in ponderosa pine forests of Colorado

Publications Posted on: February 12, 2020
Ponderosa pine forests cover more than half of the timbered lands in Colorado. This forest zone occupies most of the Colorado Front Range, the easternmost range of the central Rocky Mountain system. Here ponderosa pine is found at elevations between 6,500 and 9,000 feet. Land features consist of ridges, mountain slopes, steep rocky canyons, foothills, narrow mountain valleys, and large openings or parks.

Surface runoff and erosion from pine grasslands of the Colorado Front Range

Publications Posted on: February 12, 2020
In the Colorado Front Range, intensity of land use must be gaged with special care to maintain acceptable watershed conditions. Sparse cover, unstable soils, and intense summer rains compound the difficulties characterizing multiple-use management. Water from the Front Range is acutely needed in the adjacent Great Plains, but its quality and regularity of flow have long since been impaired by heavy grazing and unrestricted timber cutting.

Watershed management experiments in the Colorado Front Range

Publications Posted on: February 12, 2020
Summer cloudburst storms occur frequently on the eastern flank of the Colorado Range below 9,000 feet elevation. The intensity of these storms is high, often exceeding three inches per hour for 10-minute intervals. Floods from the cloudburst storms cause much damage to lands and improvements in the adjacent plains.
