  • RiversEdge West - Riparian Restoration Planning: Funding

    • RiversEdge West.

    • The mission of RiversEdge West (formerly the Tamarisk Coalition) is to advance the restoration of riparian lands through collaboration, education, and technical assistance. One of the most challenging aspects of conducting restoration work can be acquiring and maintaining adequate funding to support the full spectrum of restoration efforts. To that end, RiversEdge West has developed a variety of tools intended to help practitioners secure funding to support this work.

  • RiversEdge West Events

    • RiversEdge West.

    • Since 2001, RiversEdge West (formerly known as the Tamarisk Coalition) has been conducting riparian restoration research conferences and symposiums with a focus on impacts to riverside habitat in the arid western U.S. These gatherings are driven by RiversEdge West's commitment to advance the knowledge and practice of riparian restoration.

  • Russian Knapweed Biological Control Success with Host Specific Wasps and Midges

    • Dec 16, 2022

    • CAB International. Invasives Blog.

    • Russian knapweed (Rhaponticum repens) is a nonnative weed in the western United States. It was introduced in the late 1800’s and is now invading and degrading cropland, rangeland, riparian areas, and roadsides. This deep-rooted perennial is persistent and difficult and expensive to control by conventional means, is toxic to horses and outcompetes native vegetation by producing chemicals that inhibit plant growth. Russian knapweed is listed by the State of Colorado as a noxious weed, to be suppressed, contained, or locally extirpated.

      The Colorado Department of Agriculture (CDA) offers biocontrol agents to help suppress weeds and insect pests. When two gall-forming agents were developed and tested by CABI, and became available for use against Russian knapweed, the CDA was prepared to use them against the more than 50,000 hectares of the weed that currently infests Colorado.

  • S.C. Anglers Should Kill Invasive Snakehead If Caught

    • Oct 25, 2019

    • South Carolina Department of Natural Resources.

    • South Carolina Department of Natural Resources officials are warning anglers that if the invasive Northern snakehead fish is caught in the Palmetto State, anglers should kill it immediately and by all means NOT release it back into the water. In early October, a Georgia angler reported catching a Northern snakehead, an aquatic invasive species, in a pond located on private property in Gwinnett County, Ga. This is the first time the Northern snakehead has been confirmed in Georgia waters. In the Southeast, Northern snakeheads have also been found in North Carolina and Florida. If you believe you have caught a Northern snakehead:

      • DO NOT RELEASE IT
      • Kill it immediately (remember, it can survive on land) and freeze it.
      • If possible, take pictures of the fish, including closeups of its mouth, fins and tail.
      • Note where it was caught (waterbody, landmarks or GPS coordinates).
      • Report it to the SCDNR by calling 1-800-922-5431.

  • Safeguarding America's Lands and Waters from Invasive Species: A National Framework for Early Detection and Rapid Response [PDF, 2.26 MB]

    • Feb 2016

    • United States Department of the Interior.

    • In response to the harmful impacts invasive species have on the Nation’s natural and cultural resources, the Department of the Interior released an interdepartmental report, Safeguarding America’s Lands and Waters from Invasive Species: A National Framework for Early Detection and Rapid Response. The report proposes to stop their spread through early detection and rapid response (EDRR) actions—a coordinated set of actions to find and eradicate potential invasive species before they spread and cause harm.
