Effects of Fuel Reductions on Wildlife Populations and Vegetation

Project Title

Effects of Fuel Reductions on Wildlife Populations and Vegetation in the Middle Rio Grande Valley, New Mexico

Abstract

Along the Middle Rio Grande, the proliferation of exotic woody plants has greatly altered the structure and composition of riparian vegetative communities, and increased the frequency and severity of wildfires. Exotic plants, in particular, salt cedar (Tamarix ssp.) and Russian olive (Elaeagnus angustifolia), as well as dead and downed woody debris are fuels that lead to high fire risk in the bosque. Salt cedar’s high flammability places native bosque flora and fauna at increased risk from by fire. Native tree species, such as the Rio Grande cottonwood (Populus deltoides ssp. wislizeni) and Goodding’s willow (Salix gooddingii), are not fire-adapted, do not resist fire damage well, and do not regenerate well after fires. The increased danger of wildfires in the bosque has resulted in numerous fuel reduction projects to reduce fire danger. Little was known of what affects these habitat alterations might have on bird populations in the bosque.

In 1999, the Rocky Mountain Research Station, in cooperation with other government agencies, initiated a project to examine the effects of fuels reduction treatments. The project aimed to evaluate three types of fuel reduction treatments and their effects on bird populations. The intent was to identify the most useful fuels reduction and exotic plant removal practices that would simultaneously: 1) preserve cottonwoods and other native trees and shrubs, 2) reduce catastrophic fire risk via control of exotic plants and fuels, 3) have positive or least-negative impacts on native wildlife species and be cost effective. This project would help provide land managers with valuable information on the best fuels reductions methods to use to reduce fire danger and preserve bird populations.
