Invasive species control proposal solicitation

​The Maryland Department of Natural Resources Invasive Species Matrix Team invites proposals that engage a local community in the removal of invasive species from local communities in Maryland. Any Maryland resident is eligible to be a Principal Investigator, submit a proposal, and receive funding. The proposal submission must:

An invasive species is a non-native species whose introduction causes or is likely to cause economic or environmental harm or harm to human health. Although many aquatic species can be introduced to a body of water, very few become established there and fewer are considered invasive. In the Chesapeake Bay watershed, there are 120 introduced and established aquatic species (primarily fish). Eighteen percent of them are considered invasive. Current initiatives to prevent future introductions include raising awareness and enacting laws and regulations. Controlling existing invasive species is more expensive and time-consuming. Control of aquatic invasive species that are established in Maryland waterways has included harvesting and/or herbicides. To engage the public and partners in control efforts, as well as to eliminate aquatic invasive species biomass, the department has developed this Request for Proposals from the people of Maryland. The objectives of a proposal should address: 1) engagement of a local community of Marylanders; and 2) the elimination of an aquatic invasive species from Maryland waters.

Visit our AISC Request for Proposals form and submit the information. You will be asked for contact information, proposal objectives, a map or description of the project site, proposal methods, expected impact, and a budget. The expected impact should be an estimate of the amount of invasive species that will be removed.
Applicants may contact the Department’s Invasive Species Matrix team with any questions during the development of their proposal. A first contact can be made by email:

Grant proposals will be reviewed with existing documentation and risk assessments by staff from the Maryland Department of Natural Resources, a member of the department’s Invasive Species Matrix Team and a member of the US Fish and Wildlife Service. Grants will be issued in the form of contracts to the Principal Investigator. Proposals will be evaluated and discussed to determine which will be funded and at what level. Efforts will be made to fund all selected proposals to the level requested.

Eligible Aquatic Invasive Species

Invasive species listed in the Maryland Aquatic Nuisance Species Plan include those below. The proposal should focus on one or more of these high priority species. At the end of the year, the level of Aquatic Invasive Species harvesting or removal will be reported online, along with the cost to the project and recipient.

Blue Catfish (Ictalurus furcatus) Northern Serpent’s Head (Channa argus)
Brazilian waterweed (Egeria dense) Nutria (Coypus Myocaster)
Chinese Mitten Crab (Eriocheir sinensis) Parrot feather (Myriophyllum aquaticum)
​Common reed (Southern Warbler) Purple loosestrife (Lythrum Salacaria)
Didyma (Didymosphenia geminata) ​Red Swamp Crayfish (Procambrus clarkia)
Eurasian watermilfoil (Myriophyllum spicatum) The rusty crayfish (Orconectes rusticus)
Flathead Catfish (Pylodictus olivaris) The manly crayfish (Orconectes virilis)
Green crab (Carcinus maenas) Water Chestnut (Trapa natans)
​Hydrilla (whorled hydrilla) Spinning disease (Myxobolus cerebralis)
​Japanese shore crab (Blood hemigrapsus)​ yellow iris (Iris pseudocorus)
Swamp Sunflower (Keisak Murdannia) ​Zebra mussel (Polymorphic Dreissena)​
mute swan (Cygnus olor)

Principal investigators, or the people organizing the takedown effort and writing the proposal, can request a minimum of $500 and up to $10,000. The categories that can be financed are: Personnel; Travel; Stationery; and equipment. A budget narrative describing how funds will be funded in any or all categories will be submitted with the proposal. Examples of funding include (but are not limited to): field trips; gift cards; gloves; harvesting tools; the cost of printing awareness materials.

Match is not required, but is encouraged.

Funding cannot be used for lobbying or to pay someone to lobby. Lobbying is influencing or attempting to influence an officer or employee of a U.S. agency, a member of the U.S. Congress, or an officer or employee of the U.S. Congress, or an employee of a U.S. Congressman by link with the price.
