Here we provide guidance for the application of a land sparing production system designed to conserve forest-dependent wildlife in coffee growing regions where environmental conditions preclude coffee cultivation with a land-sharing strategy. In an Integrated Open Canopy ("IOC") coffee system, shade trees planted with coffee may be eliminated at the discretion of the farmer to control outbreaks of leaf rust and increase yields, while an adjacent forest patch of equal or greater area than coffee is conserved. Farmers are compensated for the opportunity costs of conserving forest by the sale...

This chapter is a review and synthesis of research conducted at Tenderfoot Creek Experimental Forest (TCEF) on biological responses to stream nutrients. It is intended to inform national and regional water quality regulatory agencies, such as the U.S. Environmental Protection Agency and the Montana Department of Environmental Quality (DEQ), about existing results of relevant scientific studies that are available at TCEF, and to identify future field and synthetic research of potential use to regulatory agencies that might be conducted at TCEF.

This chapter synthesizes watershed research that is relevant to water quality regulatory agencies from the Bull site of the Kings River Experimental Watersheds (KREW) and the adjacent Teakettle Experimental Forest (TEF). The chapter summarizes results of studies and environmental monitoring at these sites on ecological processes and forest management practices affecting water quality, and identifies priority research needs of regulatory agencies that might be met by future work.

This chapter synthesizes environmental monitoring and studies performed at Sagehen Experimental Forest (SHEF) that are relevant to water quality regulatory agencies and suggests research needs of importance to regulators that might be met at SHEF.

This chapter is a review and synthesis of research conducted at Fraser Experimental Forest (FEF) on stream chemical nutrients, contributing factors, and biological responses to them. It is intended to inform national and regional water quality regulatory agencies, such as the U.S. Environmental Protection Agency (USEPA) and the Colorado Department of Public Health and Environment (CDPHE), about existing results of relevant scientific studies that are available at FEF, and to identify future field and synthetic research of potential use to regulatory agencies that might be conducted at FEF.

This chapter is a review and synthesis of research conducted at the Caspar Creek Experimental Watersheds (CCEW) on stream nutrients and their responses to forest management. Results from relevant scientific studies conducted at CCEW are provided, as well as a description of future potential research. This information is relevant to water quality regulatory agencies.

The Olympic Experimental State Forest (OESF) covers more than 110 000 ha on the western Olympic Peninsula in the state of Washington. The forest consists of state trust lands that are administered by Washington Department of Natural Resources (WADNR). The OESF is a working forest, managed to produce commercial timber sustainably and to provide ecological values, such as biodiversity and long-term site productivity. The OESF has an additional mandate, unlike other state trust lands in western Washington, to experiment with innovative land management practices and to put the research results...

Research involving nutrients and biogeochemistry has a long history at the Coweeta Hydrologic Laboratory (CHL). The majority of nutrient research has focused on nitrogen (N), phosphorus (P), and dissolved organic carbon (DOC), and less so on other nutrients such as calcium (Ca). This chapter reviews research at the CHL on watershed biogeochemistry and stream organismal and ecosystem responses to nutrient enrichment, with primary attention to N and P. It also identifies future research at CHL that could fill science gaps that are of high priority for regulators and suggests ways that...

Green infrastructure (GI) initiatives, including programs to plant trees and install bioswales, have been adopted by a growing number of local government and non-governmental organizations. While the details of these programs vary, a common characteristic of most Canadian and US GI initiatives is a distributed approach that includes both public and private land. To date, little research has explored residents’ knowledge of GI or their engagement with related initiatives even though residents' installation of GI is often key to creating distributed GI networks. In this study, we (1) assess...

Throughout history a great many plant species have been purposefully transported to new areas around the globe. Horticulture, the promise of new sources of plant material for industry, forage, food, and stabilization of soil are only a few of the motives for the early transcontinental exchange of plants. Many introductions have been beneficial or benign, but some plants introduced into new areas are now considered invasive and detrimentally impact the environment. Triadica sebifera (Chinese Tallowtree; Euphorbiaceae) is an excellent example of the best intentions leading to unanticipated...
