Effect of Season and Interval of Prescribed Burns in a Ponderosa Pine Ecosystem. (Final Report, Project 01B-3-3-16)

摘要

This JFSP project contributed to the expansion and continuation of an existing study. The primary objective of the existing study was to determine the influence of season of burn (spring or fall) on the development of black stain root disease (BSRD). For that study experimental units were burned in the fall of 1997 and the spring of 1998. Funds from several sources supported the burns and collection of data on a variety of elements of the ecosystem. This project supported an expansion of the initial study to include interval of burn and to examine the influence of both season of burn and interval of burn on understory vegetation, development of disease, insect populations, and a variety of other elements of the ecosystem. Outputs from this project will utilize data collected at the initiation of the season of burn study as well as data collected during this project. Some data collected during this project may serve as the baseline for comparisons with data collected later. Outputs using data from this project that are developed after this project is officially terminated will acknowledge support by JFSP and copies of those outputs will be sent to JFSP.
