|Landowner's Guide to Managing Streams in the Eastern United States||
two streams are alike, but many share certain problems and characteristics. For example, all streams are products of the land they drain, and their waters reflect streamside land management practices, good and poor. Much can be done to protect clean streams and restore damaged ones. Since most streams originate on private lands, their fate depends largely on wise management by streamside landowners. This publication provides general information and management guidelines to help stream property owners and their neighbors protect, improve, and restore these valuable running waters.

|Liming Acidified Lakes and Ponds||
“Liming,” as the word suggests, is the addition of limestone (calcite), primarily calcium carbonate (CaCO3), to neutralize acid waters and soils and buffer them from rapid fluctuations in pH. Limestone typically is applied to lawns, gardens, pastures, and croplands to supply calcium, an essential plant nutrient, and to decrease soil acidity.

|Sustaining America's Aquatic Biodiversity - What Is Aquatic Biodiversity; Why Is it Important?||

|Sustaining America's Aquatic Biodiversity - Why Is Aquatic Biodiversity Declining?||
When a species goes extinct, all the genetic information carried by individuals of that species is lost forever, never to be reproduced again. Extinction is a terrible waste of life and a loss of potential solutions to future problems such as possible cures to disease and solutions for survival in a changing world.
