Terrestrial Invasive Species Distribution

Terrestrial invasive species distribution and management information is collected by APIPP staff, interns, contractors, partners, and volunteers. Since 1998, the APIPP Terrestrial Invasive Species Project has maintained a central database for target, new, and emerging terrestrial invasive plants posing the greatest threat to the Adirondack region. Current priority terrestrial invasive plants include: common reed grass, knotweed species, purple loosestrife, garlic mustard, yellow iris, swallow-wort species, giant hogweed, and oriental bittersweet.

2015 Priority Terrestrial Invasive Species DistributionThe majority of the Terrestrial Invasive Species Project’s survey and mapping effort has been focused in what is known as the “Core Area” of the Adirondack PRISM which is the area designated by APIPP founders as having the highest likelihood for long-term invasive species management success. This area primarily contains large tracts of “forever wild” forest preserve lands with little human disturbance, few invasive species, and small infestations. Because of this, surveys for invasive species have been focused along roadways and at trailheads, campgrounds, or other areas with high levels of associated human or natural disturbance. It is important to note that not all roads, areas of human disturbance, or backcountry areas within the Adirondack PRISM have been surveyed for terrestrial invasive species. Therefore, the lack of invasive species distribution data illustrated in certain areas of the map below does not necessarily indicate that invasive species are absent from those areas.
