1998, the Terrestrial Invasive Plant Project has maintained a
central database of inventory and management activities for the
target terrestrial invasive species posing the greatest threat
in the Adirondack Park : Japanese knotweed, purple loosestrife,
common reed grass, and garlic mustard. These data include information
collected by volunteers, staff assisting APIPP, and the NY Natural
Heritage Program. Our knowledge of terrestrial invasive plant
distributions in the Adirondack Park is largely limited to roadside
occurrences of the target species. The location information is
based on confirmed species identification and DOT roadside mileage
markers and GPS coordinates.
help focus inventory and management activities, the APIPP principle
partners designated two different management zones: the Core Conservation
Area (shown in yellow) and the Border Conservation Area (shown
in white). The Core area represents relatively intact
land and isolated invasive plant populations, suitable for eradication
and short-term controls (1-5 years). The Border area is characterized
by heavy human disturbance and large expansive populations of
plants, where long-term and permanent management controls are
The map below indicates
known occurrences of terrestrial invasive plants across the region.
Each point represents a GPS location of one or more locations
of plant populations. Distribution data are contributed by APIPP
partner organizations, volunteers, Boquet and AuSable River Associations,
Hamilton County Soil and Water Conservation District, and the
Lake George Land Conservancy.
It is important to note
that not all roads within the Park have been surveyed, and although
terrestrial invasive species may not have been identified along
a given stretch of roadway, it is possible that they might be
present and hidden by other vegetation or in landowners' backyards.
It follows that a negative survey result indicates only that an
invasive plant has not been detected and does not preclude the
possibility of its existence. If you would like to become a volunteer
and assist with either inventory or control efforts,
