USGS Restoration Assessment and Monitoring Program for the Southwest (RAMPS) is helping to build capacity in ecosystem restoration on the Navajo Nation with a series of projects in collaboration with Navajo Nation Department of Natural Hertiage, Dine Native Plant Program, and the Native-led non-profit Tolani Lake Enterprises.

Thinning rangelands by removing trees such as juniper is a common mangement action done across the intermountain west. The goals of this type of vegetation treatment typically are to increase forage and habitat for grazing animals, improve soil conditions, and/or reduce risks of catastrophic fire.

The Wildcat experimental treatment site in southwest Idaho at the base of the Owyhee Mountains. The brown square was treated with pre-emergent herbicide and is free of cheatgrass, a few native perennial bunchgrasses were able to establish. This image was taken the first Spring after treatment.

This remote area along the southern Idaho-Oregon border was affected by the 2015 Soda Fire, which burned nearly 400 square miles of sagebrush habitat important to many species of wildlife, as well as federal and private ranchlands.

Scientists are studying several weed suppressive bacteria to see if they can be used as a biological control on invasive exotic grasses, such as cheatgrass.

Biological soil crusts, or biocrusts, are lichens, mosses, and cyanobacteria that grow on the soil surface and are common in the spaces between native plants in arid and semi-arid systems. Biocrusts reduce soil erosion, contribute to nutrient and water cycling, and reduce evaporation and invasion by exotic plants.

The copious rocks carried by the September 2013 Colorado floodwaters pulverized and diluted non-floatable materials from the built environment on the Left Hand Canyon.

While sampling the sediments deposited by the September 2013 Colorado floods, the scientists observed that roads (Left Hand Canyon highway) and houses built on the outside bends of river meanders were particularly vulnerable to flood damages.
