There is a call to participate in a global survey on invasive species organizations and networks, which will close at the end of October.

The survey is a google form, available here:

The aim of this survey is to collect information about organizations working in the field of invasive alien species and to map the network of collaborations among the actors involved to support global efforts in invasive alien species management. We invite you to fill in the survey on behalf of any organization through which you are involved in studying, managing, or educating about invasive alien species.

We are interested in all organizations, from local to international in scope, based anywhere in the world. Each response should relate to a single organization or subunit of that organization, but in the case of multiple affiliations you can respond for other institutions on a separate survey by clicking the link at the end of the survey.

This survey will ask you about the following details of the organization:
- name, geographic scope, and the type of activities
- specific types of habitats and species targeted
- public outreach and communication activities
- network participation and collaborations with other organizations

The results of the survey will be published in an open access academic journal and communicated more broadly in international media and networks.

It will take you about 10 minutes to complete the survey. By completing this survey, you consent to the use of your data for the purposes outlined above. Your personal data will remain confidential and processed in accordance with data protection legislation (the General Data Protection Regulation).

Title:  Verticillium nonalfalfae as a biological control agent for Tree of Heaven (Ailanthus altissima)


Dr. Matt Kasson - Assistant Professor, Plant Pathology, West Virginia University, Davis College of Agriculture, Natural Resources, and Design


Tree of Heaven (Ailanthus altissima) is common throughout the much of the eastern United States.  This rapidly growing tree can reach heights of 80 feet, and can quickly dominate plant communities.  The biological control of Tree of Heaven has been a topic of interest since the discovery in 2002 of a destructive, naturally occurring, Verticillium wilt disease of Tree of Heaven. The pathogen Verticillium nonalfalfae is currently being studied as a potential biological control agent of Tree of Heaven.

This webinar is presented via Cisco Webex. No pre-registration required. It will be held Wednesday, October 7th, at 1PM Eastern Time.

The initial processes for successful biological invasions are transport, introduction, and establishment. These can be directly influenced or completely avoided through activities that reduce the number and frequency of entering nonnative propagules. Economic and environmental benefits through preventative monitoring programs at early stages of invasion far outweigh the long-term costs associated with mitigating ecological and economic impacts once nonnative species establish and spread. In this study, we identified 30 taxa of hitchhiking plant propagules on the air-intake grilles of refrigerated shipping containers arriving into a United States seaport from a port on the Pacific coast of South America. The four monocotyledonous taxa with the highest number of seeds collected were analyzed; we estimated propagule pressure, germination, and survivorship of these taxa, and we used the estimates to determine likelihood of establishment. At the levels of propagule pressure estimated here, non-zero germination and survival rates resulted in high establishment probabilities even when escape rates from shipping containers were modelled to be exceedingly low. Our results suggest high invasion risk for nonnative taxa including Saccharum spontaneum L., a listed Federal Noxious Weed. Currently, not all shipping containers arriving at USA ports are thoroughly inspected due to limited personnel and funding for biological invasion prevention. Our results indicate that there is a significant risk from only a few propagules escaping into the environment from this source, and we propose possible solutions for reducing this risk.

The North American Invasive Species Management Association (NAISMA) announced last week an agreement with the Comisión Nacional Para el Conocimiento y Uso de la Biodiversidad (CONABIO) in México. Both groups seek to promote environmental education to prevent, control and eradicate invasive species, and therefore saw an opportunity to collaborate.

NAISMA manages the educational outreach campaign PlayCleanGo®: Stop Invasive Species in Your Tracks. PlayCleanGo aims to change outdoor enthusiasts' behavior by encouraging hikers, bikers, boaters to clean their gear before and after playing outdoors. This simple cleaning behavior helps prevent the spread of invasive species and protect our natural areas.

CONABIO has developed the Mexican National Information System on Invasive Species, to provide information regarding biological invasions to different stakeholders, and as a basis for informed decisions. Since NAISMA aims to represent invasive species management across all of North America, collaborating with CONABIO is key to achieving the group’s mission.

NAISMA and CONABIO will collaborate by sharing resources and materials to strengthen each organization’s work. CONABIO has agreed to develop an outreach campaign in Spanish. PlayCleanGo trail signs, posters, social media awareness campaigns, and other materials will be displayed in several Mexican recreational areas, through different partners. Additionally, CONABIO will assist in translating PlayCleanGo materials from English to Spanish for use in not only Mexico, but across all of North America.

NAISMA Executive Director, Belle Bergner, is excited to enter this partnership: “We are eager to expand our efforts into Mexico and further strengthen the PlayCleanGo brand for an international audience,” she says. Bergner adds, “Furthermore, we’re excited to offer bilingual materials to our partners in the U.S. and Canada. The PlayCleanGo campaign is fun and inclusive, so offering recreationists information in their native language is one of the best ways to empower them to adopt behaviors consistent with prevention.”

Ana Isabel González-Martínez is head of CONABIO’s invasive species program and commented that, “CONABIO is very pleased to partner with the PlayCleanGo initiative as a way to strengthen regional efforts for the prevention of entry and spread of invasive species. We believe that collaboration is the key to addressing such an important issue and we look forward to implementing the program in Mexico.”

Collaboration efforts between the two groups and translation of materials has already begun. For more information on NAISMA, visit; and for more about PlayCleanGo, visit For more information on CONABIO, visit and

The U.S. Environmental Protection Agency (EPA) is accepting comments on the proposed registration of two products containing Pseudomonas fluorescens strain ACK55 (P. fluorescens ACK55), a new microbial active ingredient to be used as a pre-emergent herbicide.

Specifically, EPA is proposing to register a manufacturing-use product and an end-use product containing P. fluorescens ACK55 that will suppress the growth of invasive grasses.

Since P. fluorescens ACK55 is a naturally occurring bacterium that must become established in the soil to provide optimal pre-emergent herbicidal effects, suppression of certain invasive grasses may take two to five years.

P. fluorescens ACK55 products are expected to control grasses associated with wildfires that can lead to increased air pollution, loss of property, and loss of habitat for native wildlife.

In concurrence with the proposed registration actions, EPA will be establishing a tolerance exemption for residues of P. fluorescens ACK55 in or on all food when it is used in accordance with label directions and good agricultural practices.

P. fluorescens ACK55 is not expected to be toxic, pathogenic, irritating or infective to humans. Adverse effects to non-target organisms, including honeybees, are also not expected.

The public comment period will be open for 15 days in docket EPA-HQ-OPP-2017-0336 at, starting Sept. 9, 2020.

From the Society for Ecological Restoration, and partially funded by the Bureau of Land Management and the National Park Service.

The Society for Ecological Restoration’s International Network for Seed Based Restoration (a thematic section of SER) is pleased to announce that the First International Principles and Standards for Native Seeds in Ecological Restoration are now available as an Open Source Special Issue of Restoration Ecology. 

The growing demand for native seeds in ecological restoration and rehabilitation has resulted in a $1 billion global industry in the sourcing, supply, and sale of native seeds. Until now, there has been little international guidance for ensuring native seeds have the same standards of quality assurance that are already regular practice in the crop and horticultural industries.

Using the SER International Principles and Standards for the Practice of Ecological Restoration as a foundation document, INSR synthesized general practices in the native seed supply chain. They derived the Principles and Standards for Native Seeds ("Seed Standards") from this synthesis. These practices and the underpinning science provide the basis for developing quality measures and guidance statements that are adaptable at the local, biome, or national scale.

Importantly, the Seed Standards define what is considered native seed in ecological restoration and highlight the differences between native seeds versus seeds of improved genetics. The Seed Standards are not intended to be mandatory, however, the guidance statements provide the foundation upon which regulatory approaches can be developed by constituencies and jurisdictions.

Furthers federal actions to aggressively combat invasive species from
Guam to the Everglades

WASHINGTON, August 13, 2020 – Today, the Trump Administration released a draft strategic plan for combating an estimated $120 billion problem—invasive species. The Administration has taken significant actions to more effectively manage invasive species, which impact water supplies, impair hunting and fishing opportunities, interfere with energy production, exacerbate wildfires, damage America’s agriculture and drive native species to extinction. This plan provides a coordinated approach to further align programs and policies across the U.S. Department of the Interior and leverage more resources in addressing this important issue. In Fiscal Year 2020, Interior alone is investing an estimated $143 million to manage invasive species.

“The Trump Administration has been focused on addressing the considerable, negative impacts of invasive species by working across jurisdictional boundaries with our partners,” said Interior’s Acting Assistant Secretary for Policy, Management and Budget Scott Cameron. “The draft plan sets out a vision for effectively managing invasive species through collaborative conservation to protect our nation’s biodiversity and economy.”

In accordance with the John D. Dingell, Jr., Conservation, Management and Recreation Act of 2019, and in consultation with states, Tribes and other stakeholders, the plan both reflects ongoing work by Interior and its partners and leverages opportunities to respond to emerging issues driven by the priorities of state governors. While many Interior bureaus have invasive species management plans, this strategic plan outlines a comprehensive, agency-wide approach that will:

  1. promote partnerships to bolster mutual priorities,
  2. raise awareness to motivate action,
  3. strengthen prevention practices to avoid invasive species introductions and spread,
  4. improve the coordination of early detection and rapid response efforts across jurisdictions,
  5. leverage opportunities for targeted control and eradication and
  6. improve data collection and data management to facilitate more effective decision-making.

The Trump Administration has made significant investments to combat the devastating effects of invasive species. This draft strategic plan represents an aggressive push to continue the progress that has been made using a science-based approach and working closely with federal, state, local and Tribal partners around the nation to prevent, contain and control invasive species that damage our landscapes.

Great Lakes Region

In the Great Lakes, where Asian carp put at risk the region’s $7 billion fishing industry, the Administration invested more than $35 million in 2020 alone toward work by the U.S. Geological Survey, Fish and Wildlife Service and National Park Service to combat the spread of invasive carps, including along the Mississippi River. In collaboration with partners, Interior has conducted control activities on 153,000 acres and removed more than 8.5 million pounds of Asian carp from the Illinois River.

Florida Everglades

In the Florida Everglades, where Burmese pythons consume native wildlife and disrupt the ecosystem, a portion of the more than $20 billion the Administration has committed to restore the South Florida ecosystem will be used to combat pythons’ spread. Using new technologies such a radio telemetry, Interior for the first time is tracking pythons in many different habitats to better understand their biology and ultimately find ways to more effectively control this invasive species.

Western United States

To protect the Western United States from quagga and zebra mussels that annually cause more than $1 billion in economic impact and management costs, Interior launched numerous initiatives in 2017 in collaboration with western governors and federal, state and Tribal agencies. Under this Administration, Interior has invested approximately $41 million since Fiscal Year 2017 to identify and implement actions such as boat inspections with states, and early detection of and rapid response to mussel invasions.


Interior has been supporting efforts to eradicate brown tree snakes in Guam, where they cause $4.5 million annually in damage to electric power, tourism, recreation and national security infrastructure. Over the past four years, the Office of Insular Affairs has provided more than $12 million for the Brown Tree Snake Control program to help islanders prevent the dispersal of the snakes from Guam to other vulnerable geographic areas in the Micronesia region including Hawaii and to ultimately eradicate existing or newly established snake populations in U.S. areas.

It is a cooperative effort involving primarily Interior’s Office of Insular Affairs, the U.S. Fish and Wildlife Service and the U.S. Geological Survey; the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service, Wildlife Services; the U.S. Department of Defense; and the governments of Hawaii, Guam and the Commonwealth of the Northern Mariana Islands.

When finalized and implemented, the strategic plan will allow Interior to be a more responsive partner to state and Tribal agency requests for federal assistance to combat invasive species without adding regulations that impede business and our economy.

The draft Invasive Species Strategic Plan is published in the Federal Register for a 60-day comment period. Comments may be submitted via


Washington, D.C., August 7, 2020 – USDA’s Animal and Plant Health Inspection Service (APHIS) has expanded the list of locations where the public can send unsolicited seed packets. They have also added options for submitting reports online to APHIS or the state departments of agriculture.

APHIS urges anyone who receives an unsolicited package of seeds to submit an online report and mail their seeds to the designated USDA or state department of agriculture location in their state. If more than one location is listed, please select the location closest to your residence.

Instructions for Mailing Seed Packets:

  • Place the unopened seed packet and any packaging, including the mailing label in a mailing envelope. If the seed packets are open, first place the seeds and their packaging into a zip-lock bag, seal it, and then place everything into a mailing envelope.
  • Please include your name, address, and phone number so that a State or Federal agriculture official can contact you for additional information, if needed.
  • If you received other unsolicited items in addition to seeds, please only send the seeds.

If you are unable to mail the package, please contact your APHIS State Plant Health Director to arrange a no-contact pick up or determine a convenient drop-off location.

Washington, D.C., July 28, 2020—USDA is aware that people across the country have received suspicious, unsolicited packages of seed that appear to be coming from China. USDA’s Animal and Plant Health Inspection Service (APHIS) is working closely with the Department of Homeland Security’s Customs and Border Protection, other federal agencies, and State departments of agriculture to investigate the situation.

USDA urges anyone who receives an unsolicited package of seeds to immediately contact their State plant regulatory official or APHIS State plant health director. Please hold onto the seeds and packaging, including the mailing label, until someone from your State department of agriculture or APHIS contacts you with further instructions. Do not plant seeds from unknown origins.

At this time, we don’t have any evidence indicating this is something other than a “brushing scam” where people receive unsolicited items from a seller who then posts false customer reviews to boost sales. USDA is currently collecting seed packages from recipients and will test their contents to determine if they contain anything that could be of concern to U.S. agriculture or the environment.

USDA is committed to preventing the unlawful entry of prohibited seeds and protecting U.S. agriculture from invasive pests and noxious weeds. Visit the APHIS website to learn more about USDA’s efforts to stop agricultural smuggling and promote trade compliance.
