An environmental assessment was made of Alabama channel catfish Ictalurus punctatus farming which is concentrated in the west‐central region of the state. There are about 10,000 ha of production ponds with 10.7% of the area for fry and fingerlings and 89.3% for food fish. Food fish production was about 40,800 tons in 1997. Watershed ponds filled by rainfall and runoff make up 76% of total pond area. Water levels in many of these ponds are maintained in dry weather with well water. The other ponds are embankment ponds supplied by well water. Harvest is primarily by seine‐through procedures and ponds are not drained frequently. The main points related to Alabama catfish farming and environment issues are as follows: 1) catfish farming in Alabama is conservative of water, and excluding storm overflow, about two pond volumes are intentionally discharged from each pond in 15 yr; 2) overflow from ponds following rains occurs mostly in winter and early spring when pond water quality is good and stream discharge volume is high; 3) total suspended solids concentrations in pond effluents were high, and the main sources of total suspended solids were erosion of embankments, pond bottoms, and discharge ditches; 4) concentrations of nitrogen and phosphorus in effluents were not high, but annual effluent loads of these two nutrients were greater than for typical row crops in Alabama; 5) ground water use by the industry is about 86,000 m3/d, but seepage from ponds returns water to aquifers; 6) there is little use of medicated feeds; 7) copper sulfate is used to control blue‐green algae and off‐flavor in ponds, but copper is rapidly lost from pond water; 8) although sodium chloride is applied to ponds to control nitrite toxicity, stream or ground water salinization has not resulted from this practice; 9) fertilizers are applied two or three times annually to fry and fingerling ponds and occasionally to grow‐out ponds; 10) hydrated lime is applied occasionally at 50 to 100 kg/ha but this does not cause high pH in pond waters or effluents; 11) accumulated sediment removed from pond bottoms is used to repair embankments and not discarded outside ponds; 12) sampling above and below catfish pond outfalls on eight streams revealed few differences in stream water quality; 13) electricity used for pumping water and mechanical aeration is only 0.90 kW h/kg of production; 14) each metric ton of fish meal used in feeds yields about 10 tons of dressed catfish. Reduction in effluent volume through water reuse and effluent treatment in settling basins or wetlands does not appear feasible on most farms. However, some management practices are recommended for reducing the volume and improving the quality of channel catfish pond effluents.

________________________________________One of the central mandates of the 1964 Wilderness Act is that "each agency administering any area designated as wilderness shall be responsible for preserving the wilderness character of the area." Although wilderness comprises about 20 percent of National Forest System lands (over 35 million acres), the agency lacks a way to evaluate progress in fulfilling this mandate. This document, developed by the Forest Service Wilderness Monitoring Committee, lays the conceptual foundation for a national assessment of how wilderness character is changing over time. The purpose of this monitoring is to provide managers a tool they can use to answer key questions about wilderness character and wilderness stewardship:• What is the current state of wilderness character?• How is wilderness character changing over time?• How are stewardship actions affecting wilderness character?• What stewardship priorities and decisions would best preserve wilderness character?This monitoring uses the Section 2(c) Definition of Wilderness from the 1964 Wilderness Act to identify four statutory qualities of wilderness, from which specific monitoring questions and key monitoring indicators are derived. The status and trends of these national indicators are monitored, allowing managers to evaluate how selected conditions and stewardship actions related to wilderness character are changing over time within a wilderness. This Framework provides the conceptual basis for combining this information into a single integrated assessment of wilderness character within an individual wilderness, and whether it is degrading, stable, or improving over time. This information is compiled for upward reporting, allowing regional and national program managers to evaluate how wilderness character is changing and the effectiveness of wilderness programs and policies to preserve wilderness character. No national standards are developed or comparisons made among wildernesses in terms of their wilderness character because each wilderness is unique in its legislative, administrative, social, and biophysical setting. While this monitoring will provide vital information, it is only a portion of what could, and should, be monitored in wilderness and of wilderness character. Keywords
