Will intensive forest practices impact water quality?
Date:1/7/2008

MADISON, WI, JANUARY 7, 2008 In order to increase productivity, forest practices have become more intense in recent decades. Forest fertilization increased by 800% in the southeastern United States from 1990 to 1999, and the total acreage fertilized in the Southeast exceeds the forest area fertilized in the rest of the world. This has generated concern that intensive forest practices, including fertilization, may negatively impact water quality in forest streams.

In a recent study, hydrologists at Stephen F. Austin State University (SFASU) investigated the effects of intensive forestry on water quality in the timber-producing region of eastern Texas. The results are published in the January-February 2008 issue of the Journal of Environmental Quality.

Analysis at several small and large watersheds began in 1999. In 2002, treatment watersheds were clearcut harvested and herbicides applied to control competing vegetation. One subset of clearcut watersheds was fertilized with an aerial application of diammonium phosphate while another subset was not. Unfertilized streamside buffers of at least 15 m, consistent with Texas best management practices (BMPs), were retained on all intermittent and perennial streams.

Clearcutting with herbicide site preparation alone resulted in slight increases of nitrogen on small watersheds but not on the large one. Fertilization resulted in increased losses of nitrogen and phosphorus from both the large and small watersheds. The overall magnitude of these increases was small, with 1 to 7% of the applied nitrogen and 1 to 2% of the applied phosphorus leaving the watersheds in runoff waters. Rainfall nitrogen inputs were higher than stormflow losses of nitrogen, indicating that even after fertilization at a rate almost 30 times greater than rainfall input, these watersheds were still serving as nitrogen sinks. Peak runoff concentrations were well below published water quality standards.
