Here’s how the Pennsylvania Governor's Invasive Species Council is addressing the issue of invasive species in the Commonwealth.
Beginning in 2006, the Council was established by an Executive Order of the Governor to abate the introduction and spread of non-native invasive species in Pennsylvania. To that end, the Council's main responsibilities are to advise the Governor on significant invasive species issues impacting the Commonwealth and raise public awareness of the harm caused by invasive species to Pennsylvania's economy, environment, and the health and well-being of its citizens.
Council members currently include representatives from state agencies and nongovernmental organizations, and quarterly meetings are open for public attendance. Kristopher Abell serves as the Council Coordinator and can be contacted for questions about the Council and its activities.

Council Overview
Pennsylvania's diverse geography is home to thousands of species. Unfortunately, not all of these organisms are beneficial. The Council recognizes that invasive species present a significant threat to the Commonwealth.
Pennsylvania's natural resources and economy are threatened by unwanted invaders in the Commonwealth – non-native invasive species that can:
Outcompete and decrease diversity of our native plants, insects, and wildlife
Decrease agricultural crop yields and increase the cost of cultivation
Damage critical infrastructure like roads, bridges, storm water management, and riparian buffers
Impact human health directly by vectoring diseases such as the West Nile Virus, or indirectly by increasing the incidence of Lyme disease
The value of Pennsylvania's natural and economic resources, and the need to protect the health of Commonwealth citizens, demands an effective response to the impacts of invasive species. Such a response requires cross-jurisdictional cooperation to include multiple state agencies and nongovernmental organizations. Therefore, the Pennsylvania Governor's Invasive Species (PGISC), created by Executive Order in 2006, collaborates on several initiatives related to the recommendations set forth in the Pennsylvania Invasive Species Management Plan.
The Council hosts events throughout the year including field tours, legislative and public hearings, and Pennsylvania Native Species Day celebrations. Each of these events highlight the harmful impacts of invasive species and the benefits of protecting and restoring the state's diverse native species. Recent news, upcoming events, and other engaging content about invasive species in Pennsylvania are highlighted in quarterly newsletters released by the Council that are available to the public.
About
Actions Require Funding: In 2009, the Council created the first Pennsylvania Invasive Species Management Plan as part of its directive from the Governor's Executive Order creating the Council. The newest version of the plan (released in 2025) lists 24 recommendations associated with actionable items for implementation to improve invasive species management in the Commonwealth. However, many of these recommended actions require funding to be accomplished, with some requiring significant levels of funding.
Limited Funds & Scope of Work: Currently, invasive species management funding is largely limited to select programs on public lands, and the funds are often limited in the scope of how they can be applied. Support from other sources of funds that expand the types of lands and waters where restoration projects occur could go far to reduce invasive species and improve ecological restoration on public and private lands and waters.
Top Priority: It is therefore the Council's highest recommendation that additional state funds be allocated for use by the Council to advance invasive species management, specifically to implement the recommendations made in the statewide management plan.
According to the Executive Order that established the Pennsylvania Governor's Invasive Species Council, the Council is tasked with the following responsibilities:
PA Invasive Species Management Plan: Develop and implement a comprehensive non-native invasive species management plan for this Commonwealth and revise the plan at regular 5-year intervals, or as needed.
Provide Guidance: Provide guidance on prevention and control of non-native invasive species and rapid response to new infestations. The Council shall utilize scientific methods and procedures to assist in developing this guidance. In addition, the Council may consider the potential for widespread harm to public health, an ecological system, or the economic benefit derived from a non-native species to determine whether control measures are needed.
Facilitate Coordination: Facilitate coordination among federal, regional, state, and local initiatives and organizations engaged in the management of non-native invasive species.
Host Quarterly Meetings: Convene at least quarterly and at the call of the Chairperson of the Council.
Submit Biennial Report to Governor: Submit to the Governor a biennial report on the Council's activities.

The purpose of the Pennsylvania Invasive Species Management Plan is threefold:
Outline the components of invasive species management needed to protect the Commonwealth, most notably the need for sustainable funding from the state legislature
Provide recommendations to improve interagency cooperation and collaboration with stakeholders
Make policy and procedural/program recommendations that address current shortcomings of invasive species management in Pennsylvania
The Council drafts and updates an aquatic invasive species response plan which provides guidance and procedures for responding to new infestations of aquatic invaders in the Commonwealth.
Every two years, the Council prepares a report for the Governor. This report provides recommendations and highlights progress the Council has made to advise, facilitate, and improve invasive species management in Pennsylvania.
This strategic plan will guide the efforts for a proposed Partnerships for Regional Invasive Species Management (PRISM) program in Pennsylvania.
Grant Opportunities

Projects must impact or be located within the 112-mile stretch along the Delaware Estuary or 77 miles along Lake Erie.
Community Conservation Partnership Program - This Department of Conservation and Natural Resources (DCNR) program partners with communities and organizations across Pennsylvania to provide grants and technical assistance support for local recreation projects, trails and greenways, heritage areas, open space protection, river conservation, and environmental education programs.
Environmental Education Grants - This DEP program funds formal and informal education projects for youth and adults, with priority given to projects on climate, nonpoint source water pollution, and Environmental Justice.
Greenways, Trails, and Recreation Program - This Department of Community and Economic Development program provides funding for planning, acquisition, development, rehabilitation, and repair of greenways, recreational trails, open space, parks and beautification projects.
Growing Greener Plus Grants Program - Growing Greener Plus funds projects that help reduce nonpoint source water pollution through local, watershed-based planning, restoration, and protection efforts. It's the largest and most recognized grants program of DEP.
Pennsylvania Wild Resource Conservation Program - The Wild Resources Conservation Fund was created in 1982 to, among other things, aid in the conservation of the Commonwealth’s flora and non-game fauna. It set up the ability for citizens to support the management of wild resources by creating a contribution opportunity through a tax check-off and license plate program, furthering management and conservation. Each year, these funds support the survey, research, management, and conservation of wild resources through the Department of Conservation and Natural Resource’s Wild Resource Conservation Program.
Forest Health Protection Grants - This U.S. Forest Service program funds projects in forest monitoring, biological control of invasive forest pests, evaluation of pesticide impacts, and cutting-edge technology to restore and protect forests.
Great Lakes Restoration Initiative Funding - The Great Lakes Restoration Initiative (GLRI) accelerates efforts to protect and restore the largest system of fresh surface water in the world – the Great Lakes.
Landscape Scale Restoration - This U.S. Forest Service grants program supports collaborative, science-based restoration of priority forest landscapes and furthers priorities identified in State Forest Action plans. Applications must be submitted in collaboration with the PA State Forester.
Plant Protection Act 7721 Funding - The U.S. Department of Agriculture's Animal and Plant Health Inspection Service provides funding through the Plant Pest and Disease Management and Disaster Prevention Program and the National Clean Plant Network Programs under the authority of the Plant Protection Act, Section 7721.
Environmental Quality Incentives Program – This program offers technical and financial assistance for working lands, including field crops, specialty crops, organic, confined livestock and grazing, and non-industrial private forest land. Rather than take land out of production, EQIP helps farmers maintain or improve production while conserving natural resources on working landscapes. Brush management (for invasive species) has a $30,000 project cap. Applications require a forest management plan meeting NRCS requirements. Below are some components that could be contracted for brush management:
Biological control, high or low density
Chemical control, aerial or ground application; individual plant treatment

The Foundation is looking for creative and innovative projects that promote safe and clean boating on your local waterway. Past topics have ranged from PSAs on the effects of boating under the influence to hands-on education about the effects of marine debris.
Mid-Atlantic Aquatic Invasive Species Panel - The mission of the Mid-Atlantic Panel of Aquatic Invasive Species (MAPAIS) is to assist state and federal agencies and other stakeholders in developing and implementing strategic, coordinated, and action-oriented approaches to preventing and controlling aquatic invasive species (AIS) in the mid-Atlantic region. The driving force behind the mission is to strengthen cooperation, coordination, and communication on AIS issues within the region and beyond. MAPAIS offers an annual small grants competition and encourages broad participation from groups and individuals concerned about AIS issues in the mid-Atlantic region. A proposal submission must address an AIS problem.
South Mountain Mini Grant Program - Spanning approximately half a million acres in Adams, Cumberland, Franklin, and York counties, the South Mountain landscape is one of Pennsylvania's more unique regions. The program provides funding, on a competitive basis, to projects that sustain the South Mountain landscape's sense of place by protecting and promoting the region's landscape resources.
Watershed Protection Grant Program - This William Penn Foundation program supports science, policy, practice, and communications projects in the Delaware Watershed focused on surface water quality and watershed health and protection.
Why Protect Pennsylvania's Native Species?
Pennsylvania is home to a diverse array of native plants, trees, insects, fish, birds, and mammals that originated thousands of years ago and thrive in mutual dependence. This native ecosystem provides Pennsylvanians with natural resources that benefit our lives by enabling agricultural food production, recreation, fisheries, timber, and more.
As humans have increased worldwide commerce and travel, non-native species have crisscrossed the world with us. When species are transported to areas outside their native range, they have no natural predators. They often invade, crowding out and threatening the survival of native species. Thus, the protection of the Commonwealth's native plants and animals is critical to a healthy economy, a functioning and biodiverse ecosystem, and the health and well-being of Pennsylvania citizens.
Non-native trees and shrubs are widely found in much of Pennsylvania, including but not limited to Callery pear, tree-of-heaven, Norway maple, burning bush, Japanese barberry, and butterfly bush. While many of these species are planted to add beauty and ornamental value to a landscape, numerous unsuspecting homeowners and commercial landscapers may not realize the negative ecological and economic impacts these species can have on nearby natural areas.
Removing invasive plants helps reduce the likelihood of them becoming unwanted escapees into neighboring properties, parks, and forests. As part of the Pennsylvania Invasive Replace-ive Program, property owners are incentivized to remove unwanted invasive plants from their landscape in order to receive free native trees and shrubs that can be planted in their place.
Subcommittees and Groups
Several subcommittees and other groups have been established by the Council to advance the initiatives outlined in the Pennsylvania Invasive Species Management Plan. Other independent groups such as the state's CWMAs and the Controlled Plant and Noxious Weed Committee work on supplementary invasive species initiatives.
From the efforts of its subcommittees and other groups, the Council advises the Governor on invasive species policy development, conducts education and outreach, facilitates coordination between agencies and organizations to address invasive species threats, and more. Subcommittees and related groups are comprised of Council members and those interested in the work of the Council. To join a subcommittee or other group, contact the respective Chairperson of the group you are interested in.
Additional groups that are independent from the Council also work on invasive species initiatives including the state's five Cooperative Weed Management Areas (CWMAs) and the Controlled Plant and Noxious Weed Committee.
Council Subcommittees & Groups
Chairperson: Amber Stilwell, PA Sea Grant and Master Watershed Steward Program (ars26@psu.edu)
The Aquatic Invasive Species (AIS) Education and Outreach Subcommittee meets quarterly and provides a platform of collaboration, idea generation, and sharing of upcoming outreach opportunities, all in relation to AIS.

Chairperson: Andrew Rohrbaugh, PA Department of Conservation and Natural Resources (anrohrbaug@pa.gov)
The Invasive Species Listing Subcommittee meets every 2-3 months and is currently completing several invasive plant assessments. The group also plans to revisit/review the list of plants originally voted on by PGISC as suggestions for inclusion on the Controlled Plant & Noxious Weed Committee list. (Note: In 2020, the Listing Subcommittee recommended a "Top 25" List of Invasive Plants for consideration by the Controlled Plant and Noxious Weed Committee to add to the Pennsylvania Noxious Weed List.)
In the past, committee members have also developed an invasive species list for Pennsylvania which includes about 300 plants, insects, fungi, pathogens, and animals. This list helps inform development of regulation, policy, and education to protect our agricultural and natural resources. Species included on the list were determined to have the greatest current or potential negative impacts on Pennsylvania. The committee also developed an assessment protocol to prioritize species on the list.
Chairperson: Eve Adrian, PA Department of Agriculture (eadrian@pa.gov)

Jim Zoschg, Cameron County Conservation District (jzoschg@cameroncd.org)
Jon-Marc Burdick, Cameron County Conservation District (jmburdick@cameroncd.org)
Overview: The Sinnemahoning Invasive Plant Management Area (SIPMA) is a cooperative weed management area (CWMA) formed in 2010-2011 by the collaboration of diverse partners—private landowners, non-profit conservation organizations, government organizations, state agencies, commercial landowners, and forest resource companies—in order to work together to address the short- and long-term effects of non-native invasive plants within the Sinnemahoning Creek Watershed.
SIPMA partners agree that it is to their mutual interest and benefit to work cooperatively in inventorying, monitoring, controlling, and preventing the spread of non-native invasive plants across jurisdictional boundaries within the Sinnemahoning Creek Watershed. The spread of invasive plant populations does not adhere to property boundary lines even though traditional invasive plant control efforts are often confined to one property. However, through the CWMA, SIPMA can partner with landowners—private, commercial, and governmental—to address invasive plant populations across property boundaries in a watershed approach to the issue.
SIPMA also serves as a forum to share information regarding the control of invasive plants and to cooperatively seek funding for this work. Currently, SIPMA partners meet virtually twice a year, one in the spring and once in the fall, to share information and coordinate work. Each of the coordinators focuses on a specific component of the CWMA’s operations. Jon-Marc manages the CWMA’s grants and Jim works with contractors and engages in field-based activities.
Management Plan: None at present
Focus Area: The SIPMA covers the Sinnemahoning Creek Watershed, which encompasses portions of Cameron, Clearfield, Clinton, Elk, McKean, and Potter counties, accounting for 1,011 square miles.
Mission: The mission of the SIPMA is to protect and restore habitat through the cooperative identification and management (i.e., suppression, control, or eradication) of noxious and exotic invasive plants in the Sinnemahoning Creek Watershed.

Management Plan: Members of the Southern Laurel Highlands Plant & Pest Management Partnership (SLHPPMP) are required to have their own management plans for invasive species management activities conducted on their property. Contact Heather Fowler for more details on each of the respective plans.
Focus Area: The SLHPPMP focuses its efforts on parts of Westmoreland, Somerset, and Fayette counties in Southwest Pennsylvania. Members of the partnership conduct invasive species management activities on properties located within the Southern Laurel Highlands. For reference, a map of member properties is provided below.
Mission: The mission of the SLHPPMP is to protect the unique and diverse natural resources of the Southern Laurel Highlands by reducing the impact of invasive species. The SLHPPMP seeks to foster a coordinated and cooperative approach to regional invasive plant and pest management and to educate the public about the benefits of Pennsylvania’s native species.

Regulatory Committees
The Pennsylvania Controlled Plant and Noxious Weed Committee is overseen by the Bureau of Plant Industry at the Pennsylvania Department of Agriculture and is not affiliated with the Council, though updates of recent committee proceedings are often highlighted at Council meetings
Chairperson: Trilby Libhart (PA Department of Agriculture) (tlibhart@pa.gov)
The Controlled Plant and Noxious Weed Committee votes to add or amend/remove species from the Pennsylvania Controlled Plant and Noxious Weed List. Species on this list are regulated by state law and include many invasive species.
In 2021, the Council compiled a list of 25 recommended species for consideration by the committee to include on the Controlled Plant and Noxious Weed List. Since that time, several of the Council's recommended species have been added to the list.
Currently, about 300 invasive species have been identified as having the greatest current or potential impacts for the Commonwealth. The following lists are provided to inform development of regulation, policy, and education to protect our agricultural and natural resources.
Species List
More than 140 invasive plant species pose significant risk of negative impacts for Pennsylvania. Each species has an overall priority score from 1 to 10 based on a 2021 survey of Council members. Risk of invasiveness, threat to state lands and natural areas, and importance to the landscape and nursery industry are scored. Also indicated is whether the species is on the Pennsylvania Controlled Plant and Noxious Weed List. You'll find other useful information in this searchable and sortable comprehensive list.
There are 28 insects of greatest concern for Pennsylvania. Spongy moth, Japanese beetle, hemlock woolly adelgid, and brown marmorated stinkbug are established and having substantial negative impacts. Spotted lanternfly, box tree moth, and other species aren’t yet completely established, but are in the state and spreading quickly to new areas. Asian longhorned beetle, northern giant hornet, and other insects haven’t yet arrived in Pennsylvania but pose considerable threat.
Almost 60 invasive aquatic animals are identified as of greatest concern for Pennsylvania, from highly impactful emerging species, like zebra mussels, quagga mussels, and northern snakehead, to not-yet-present but potential major concerns, including silver carp and bighead carp. These must be prevented from being introduced.
Asian jumping worm and broadhead planarians are emerging threats to forests and natural areas and have been found in some parts of Pennsylvania. Some snail and slug species aren’t yet found in Pennsylvania but have the potential to greatly impact field and greenhouse agriculture.
Five bird and mammal species are of concern, including feral swine, which have limited distribution to date in Pennsylvania but considerable potential for negative impacts, and the rodent nutria, which hasn’t been detected yet but is potentially a significant problem.
There are 21 introduced fungi of greatest concern that are pathogens of plants and animals, that threaten native fungal biodiversity, or are poisonous to humans. This list includes saprotrophic and mycorrhizal mushrooms as well as pathogenic microscopic fungi.
There are 25 non-fungal pathogens of greatest concern that impact plants and animals in Pennsylvania.
The Council's education and outreach resources aid in promoting accurate and current information on invasive species and related issues occurring in Pennsylvania. All items are available online and encouraged for public use.
Items include:
Videos and films
Field guides, fact sheets, and brochures
Esri products (Dashboard, StoryMaps)
Media appearances and podcasts
News stories and blog posts
Journal articles
Rapid response case studies
Webinars
The vast task of preventing and managing invasive species in Pennsylvania is spread across diverse entities—agencies with authority to regulate organisms under their jurisdiction, and public land managers and land trusts that control invasive species. Each entity with representation on the Council has an official appointed member, and in some cases, a designee or alternate member(s).

Throughout the Commonwealth, more than 300 species have been identified as invasive threats to the economy, environment, and human and animal health. All Pennsylvanians have an important role to play in the fight against invasive species by submitting reports of known or suspected invasive plants, animals, and insects.
Early detection of invasive species helps enable regulatory agencies and natural resource professionals to better control known pests and other problematic species and respond rapidly to new ones. In Pennsylvania, there are a variety of ways to report findings of invasive species and certain types of invasive species can be reported to more than one entity (i.e., noxious weeds, aquatic organisms, etc.). If you suspect you've found any of the following regulated species, please submit an initial report to the appropriate state agency. Additional reports can also be submitted to iMapInvasives and/or Sea Grant.
Individuals are encouraged to submit their findings to iMapInvasives, an online platform that accepts reports for all taxa of invasive species and allows natural resource professionals and community scientists to visualize and better understand species distributions both locally and statewide. Reports submitted to PA Sea Grant provide an additional avenue for information to be directed to the Pennsylvania Fish & Boat Commission.
