Threatened and Invasive
Maine Natural Areas Program is the primary agency that has collected
information about plants in the York River watershed. Their
database does have a concentration of data in Southern Maine, but
the agency does not generally release data except by special request
in order to minimize damage to rare plants.
Natural Areas Program collects information about plants that are
state-listed as Rare, Threatened, or Endangered, and about Rare
or Exempliary communities. The Natural Areas Program does
not have a written report on the York area, but they do have a
GIS database with locations, habitats, legal status, etc.
specific parcels are being considered for protection, the Natural
Areas program is able to release any information they may have
about important habitats/plants in support of funding proposals.
Natural Areas Program is working with land trusts to identify
habitat at a landscape-level; this program is in conjunction with
Inland Fisheries & Wildlife, Maine Coast Heritage Trust, and
the Maine Audubon Society. However this program is available
only to a few pilot land trusts. The York Land Trust is
working to become one of these. However, this effort would
still be based on somewhat spotty survey data.

Invasive species have not been mapped or catalogued.
Endangered and threatened species data is incomplete.
More habitat sites will be surveyed in the summer of 2000 for
the Southern Maine ecosystem, through a joint program of the
Natural Areas Program and Inland Fisheries & Wildlife's
Endangered Species Group. However, field biologists will
be able to survey only targetted sites due to limited funding.

of Inland Fisheries and Wildlife, block off at very broad scale,

available in the York Planning Office, and are used in DEP's permitting
process under the Natural Resources Protection Act.

Maine had a task force on invasive plants, but there has not yet
been an attempt to inventory the extent of Maine's invasive problem.

not pinpoint a particular species to a particular location,
