Effects Of Prescribed And Wildland Fire
On Aquatic Ecosystems In Western Forests
Principal Investigators:
David Pilliod - ALWRI and USFS, Steve Corn - USGS, ALWRI and NRMSC, Bruce
Bury, Chris Pearl, and Erin Hyde - USGS Forest and Rangeland Ecosystem
Science Center
Funding Source: This project is supported by R1/R4 National Fire
Plan Adaptive Management and Monitoring funds and the Joint Fire Science
Program.
Collaborators:
University of Idaho
Research Objective:
The goal of the project is to understand how fire in upland and riparian
forests influences stream communities and determine whether prescription
burning mimics the ecological function of fire in a watershed. The project
has two components: wildland fire and prescribed fire.
Wildland Fire Effects
To document the range of biotic and abiotic responses to wildland fires,
we
are comparing stream communities and habitat conditions in watersheds
that
burned, at varying intensities, to streams in unburned forests (fires
absent for 50-70 yrs).
Prescribed Fire Effects
To determine whether prescription burning restores the "ecological
integrity" of forests, we are monitoring stream communities and habitat
conditions before and after prescription burn treatments and comparing
observed responses to unburned reference streams during the same time
periods.

Background:
Prescription burning is an important management tool for reducing fuel
loads and restoring natural fire cycles to fire-adapted western forests.
A
general lack of information on the effects of fire on sensitive aquatic
species is a major impediment to developing ecologically sound fire
management policies and evaluating fuel treatment projects on federal
lands. Several amphibian and invertebrate species in the western U.S.
are
sensitive to disturbances that alter aquatic and riparian habitat
conditions and water quality, and thus understanding the effects of fire
and fuel reducing management actions on stream ecosystems is increasingly
important.
