U.S. Fish And Wildlife Service Response To The Catfish Farmers Of Arkansas Information Quality Act (Iqa) Request For Correction

National Invasive Species Council

In February 2000, the U.S. Fish and Wildlife Service (Service or we) received a petition from the Mississippi Interstate Cooperative Resources Association (MICRA) to list the black carp (Mylopharyngodon piceus) under the injurious wildlife provision of the Lacey Act (18 U.S.C. § 42). On June 2, 2000, we published an advance notice of proposed rulemaking (ANPR) (65 FR 35314) to seek comments on whether or not we should propose to list black carp as injurious under the Lacey Act.

Factors Controlling Patterns Of Canada Thistle (Cirsium Arvense) And Yellow Starthistle (Centaurea Solstitialis) Across The Cascade-Siskiyou National Monument, Paul E. Hosten

National Invasive Species Council

Landscape patterns of broadleaved noxious weeds across the Cascade-Siskiyou National Monument are examined in the context of environmental and management factors to improve our understanding of weed dynamics. Environmental factors include a range of topographic edaphic variables, while management factors provide insight about historic vegetation manipulation, road construction and forage utilization by wildlife and livestock. Distribution patterns of Canada thistle (Cirsium arvense) and yellow starthistle (Centaurea solstitialis) across the Monument are best described by a combination of topographic, edaphic, biotic, and management factors. Variables incorporated within models describing landscape patterns of weeds varied with response variable …

Training And Implementation Guide For Pathway Definition, Risk Analysis And Risk Prioritization

National Invasive Species Council

The purpose of pathway risk analysis is to provide scientific analyses and policy recommendations in support of U.S. National Invasive Species Council’s Management Plan. These analyses and recommendations must comply with the Plan’s mandates to:

• ensure Federal efforts are coordinated and effective

• promote action and partnership at local, State, tribal and ecosystem levels

• identify recommendations for international cooperation; and,

• facilitate networks to document, monitor and prioritize invasive species pathways

Though many definitions for invasive species and pathways may exist, we are defining these terms as they relate to Federal regulatory functions. Definitions are recounted, below:
