Invasive species pose a major, yet poorly addressed, threat to sustainable forestry. Here we set forth an interdisciplinary science strategy of research, development, and applications to reduce this threat. To spur action by public and private entities that too often are slow, reluctant, or unable to act, we recommend (a) better integrating invasive species into sustainable forestry frameworks such as the Montréal Process and forest certification programs; (b) developing improved cost estimates to inform choices about international trade and pest suppression efforts; and (c) building distributed information systems that deliver information on risks, identification, and response strategies. To enhance the …

A Retrospective Analysis Of Known And Potential Risks Associated With Exotic Toadflax-Feeding Insects, Sharlene E. Sing, Robert K.D. Peterson, David K. Weaver, Richard W. Hansen, George P. Markin Jan 2005

A Retrospective Analysis Of Known And Potential Risks Associated With Exotic Toadflax-Feeding Insects, Sharlene E. Sing, Robert K.D. Peterson, David K. Weaver, Richard W. Hansen, George P. Markin

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

To date, eight exotic toadflax-feeding insect species have been accidentally or intentionally introduced to North America. Reports on their establishment and impact have been recorded for more than 60 years. Environmental risks linked to biological control of toadflax were identified in terms of host resources and undesirable impacts on the target species through the critical review of this record. Data gaps revealed during this retrospective analysis are addressed through suggestions for future research and associated experimental methodologies. Known and potential impacts of toadflax-feeding insects on both invasive toadflax and non-target species are examined. Recent programmatic demands for demonstrated agent efficacy …

Environmental Quality Incentives Program Contributions To Fish And Wildlife Conservation, Mark W. Berkland, Charles A. Rewa Jan 2005

Environmental Quality Incentives Program Contributions To Fish And Wildlife Conservation, Mark W. Berkland, Charles A. Rewa

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The Environmental Quality Incentives Program (EQIP) is a voluntary program whereby the U.S. Department of Agriculture provides technical and financial assistance to active farmers and ranchers to address natural resource concerns such as soil conservation, water quality and quantity, nutrient management, and fish and wildlife habitat. The Natural Resources Conservation Service (NRCS) is working with these landowners to maximize the environmental benefits gained for the expenditures made in the program. Funding has expanded significantly under the 2002 Farm Bill, with the amount of annual funding authorized reaching $1.3 billion by fiscal year 2007. The EQIP has been used to implement …

Fish And Wildlife Benefits Of The Wildlife Habitat Incentives Program, Randall L. Gray, Sally J. Benjamin, Charles A. Rewa Jan 2005

Fish And Wildlife Benefits Of The Wildlife Habitat Incentives Program, Randall L. Gray, Sally J. Benjamin, Charles A. Rewa

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Th e Wildlife Habitat Incentives Program (WHIP) is a voluntary program that encourages the establishment and enhancement of a wide variety of fish and wildlife habitats of national, state, tribal, or local significance. Through voluntary agreements, the Natural Resources Conservation Service (NRCS) provides financial and technical assistance to participants who installed habitat restoration and management practices. Since 1998, nearly $150 million has been dedicated to the program and over 2.8 million acres involving over 18,000 contracts have been enrolled. A wide range of habitat-enhancement actions are cost-shared through the program, affecting hundreds of target and non-target species. While few quantitative …

Wildlife Benefi Ts Of The Wetlands Reserve Program, Charles A. Rewa Jan 2005

Wildlife Benefi Ts Of The Wetlands Reserve Program, Charles A. Rewa

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Since its initial authorization in 1990, more than 1.6 million acres of primarily drained or degraded wetlands on agricultural lands have been enrolled in the U.S. Department of Agriculture’s (USDA) Wetlands Reserve Program (WRP). The Natural Resources Conservation Service (NRCS) and its partners are working with landowners to restore these lands to ecologically productive wetland and upland buffer habitats. Numerous studies have documented the value of restored and created wetlands to fish and wildlife resources. However, few objective studies have been completed that document fish and wildlife response to wetlands enrolled in and restored through WRP. Preliminary results of some …

Biology And Biological Control Of Knapweed, Linda M. Wilson, Carol Bell Randall Jan 2005

Biology And Biological Control Of Knapweed, Linda M. Wilson, Carol Bell Randall

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The knapweeds comprise a diverse complex of species that predominantly infest rangelands in the western United States and Canada. This manual considers the biological control of six species of knapweeds: 1) spotted knapweed, 2) diffuse knapweed, 3) squarrose knapweed, 4) meadow knapweed, 5) black knapweed, and 6) brown knapweed. Spotted knapweed, Centaurea stoebe, is perhaps the most widespread species, followed in abundance by diffuse knapweed, C. diffusa. A third species, squarrose knapweed, C. virgata var. squarrosa, has a more limited distribution in the West. Three less widespread species, meadow (C. pratensis), brown (C. jacea …
