NEANS Releases Hydrilla Literature Review

The review of the body of scientific publications Monoecious Hydrilla – A Review of the Literature has been released by NEANS (the Northeast Aquatic Nuisance Species Panel).


Hydrilla verticillata is a submersed aquatic weed that has become one of most expensive and difficult to manage in the United States. There are two biotypes of Hydrilla found in the United States, a dioecious and a monoecious biotype. The monoecious biotype is typically found from North Carolina northward and is rapidly spreading. The body of research focusing on strictly the monoecious biotype is much smaller than that of the dioecious, as reflected in the literature. A search with BIOSIS yielded 1,246 articles with the topic ‘hydrilla’; only 53 of those had the additional topic ‘monoecious’. Many publications on Hydrilla make no mention of biotype, therefore only an educated guess can be made based on study locations to decipher biotype. Provided is a comprehensive overview of published research on monoecious Hydrilla.

PDF versions of the literature review and its appendix, Cited Articles and Abstracts, can be found on the NY Invasive Species Clearinghouse website (NYIS.INFO) by clicking the following links or going to the NYIS.INFO Hydrilla profile page and looking under Resources :

NYS DEC hiring seasonal giant hogweed control personnel

NYSDEC (Department of Environmental Conservation) Forest Health and Protection is looking for up to twelve people to control giant hogweed throughout central and western NY on private and public lands. The job entails educating the public about giant hogweed, contacting landowners, controlling giant hogweed using herbicide or root-cutting control methods, collecting site information and creating GIS polygons. It is a very rewarding but physically challenging position. We are looking for professional, self-directed people with strong communication skills who have the ability to identify and control giant hogweed.

Three two-person crews will use a manual root-cutting control method and three two-person crews will use primarily herbicide control methods. These 4 month positions will start April 15 and will be located out of one of several Regional DEC offices in Regions 7, 8 and 9 (Allegany, Avon, Bath, Cortland, Reinstein Woods (Depew)).

Long Island Invasive Species Management Area (LIISMA) issues 2011-2012 Annual Report

 Moving Forward 2011-12, 2011-2012 annual report for the Long Island Invasive Species Management Area (LIISMA) s now available.


The mission of the LIISMA PRISM (Partnership for Regional Invasive Species Management) is to conserve biodiversity, wildlife habitat, recreation resources, scenic quality, and crop production, while protecting human health and safety, by facilitating cooperation and coordination among land managers and owners to reduce the threat of invasive plants. The PRISM’s goals are to:

  • Build partnerships and facilitate coordination among stakeholders.
  • Train agency staff and volunteers in identification, prevention, mapping, monitoring, and management protocols.
  • Detect and rapidly respond to new invaders.
  • Monitor changes and evaluate results of management efforts.
  • Elevate the profile of the invasive species issue through education and outreach with an emphasis on prevention measures and Best Management Practices (BMPs).
  • Establish new funding, policy, and management support at the State, County and Town levels.


Some highlights of the report include:


Education and Outreach

  • LIISMA partners were instrumental in providing many education opportunities about invasive species to the public, professionals, and students. [Activities are listed]
  • LIISMA provided five grants up to $25,000 for projects that included an education component. These were provided to four organizations on Long Island. [Projects are listed]


Monitoring and Early Detection

  • LIISMA and its partners continued mapping and monitoring known invasive species. The partnership continues to review and refine the procedures for early detection and early assessment so new species can be recorded in a systematic way that, in addition to iMapInvasives, will provide a complete record of the disposition of the species. There were 30,541 records entered into iMap for LIISMA this year including bulk downloads from organizations, field mapping and mobile uploads to the iMap mobile website.


The LIISMA Survey of Low Abundance Species

  • In order to supplement exclusion, containment, and suppression work on common invasive species, LIISMA funded work on surveying low abundance exotic species on Long Island. The purpose of the project was to gather location information from specimens and reports of 30 likely invasive species with only one to three locations on the island so they could be eradicated while they are still in low abundance.


Supporting Academic Research

  • LIISMA is supporting academic research by facilitating communication about the projects among partners and the scientists and by helping to fund others. [Research projects are included]


Prevention and Management Projects

  • Prevention is a major strategy employed by LIISMA. The PRISM continues to support the do-not-sell lists of invasive horticultural species in Suffolk and Nassau counties and the effort by the state to compile statewide lists. A number of partner invasive species management projects continued through 2011 and the first half of 2012. [Sample projects are listed]
  • The PRISM also directly funded three management projects, which are discussed in the report.
