The $900,000 grant will help Virginia Tech researchers see if the spotted lanternfly can help spread a fungus that kills the tree-of-heaven. The goal of the grant is to develop a native fungus as a biocontrol for the tree-of-heaven. Researchers are investigating whether the spotted lanternfly could help transmit the fungus from tree to tree, reducing the need for human intervention.

The Lionfish Challenge 2022, the seventh annual, is a summer-long tournament that rewards divers for their lionfish harvests. The tournament boasted a total of 707 registered participants, the most in the program’s history. 196 divers conducted a total of 676 trips throughout the state during the 3-month tournament and brought in a whopping 25,299 lionfish.

The widely cited “tens rule” in invasion ecology suggests that approximately 10% of established, non-native species will become invasive–or display negative impacts—when introduced to new environments. This study demonstrates that the tens rule is a poor estimate of invasion rates on a global scale. Instead, a ‘twenties rule’ is a better rule of thumb, meaning that roughly 20% of all established, non-native species eventually become invasive

Special Note: RiversEdge West formerly known as the Tamarisk Coalition, change effective Mar 1, 2018.

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.

"Rooted in Research" is the Northern Research Station's science delivery platform, with events and products tailored to natural resource professionals, partners, collaborators, and engaged citizens throughout the Northeast and Midwest. The bimonthly Rooted in Research focuses on the management implications of the latest research for natural resource managers. This publication features synthesized scientific information for high-priority land management needs, delivering key science findings to people who make and influence decisions about managing land and natural resources.

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.

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.

The Port of San Diego, along with the Southern California Caulerpa Action Team (SCCAT), the City of Coronado, and the Coronado Cays Homeowners Association (CCHOA), are responding to the discovery of an invasive seaweed scientifically known as Caulerpa prolifera in the Coronado Cays area of San Diego Bay.

In late September, divers found a small patch of Caulerpa prolifera while conducting an in-water pre-construction eelgrass/Caulerpa dive survey as a permit condition for a dock replacement project. Additional patches were discovered nearby during follow-up surveys. The total find within the Cays is about one-quarter of an acre. The SCCAT has prepared a Rapid Response Eradication Plan to address the immediate need to eradicate this invasive species.
