In the world of invasive species, early detection is crucial – for instance, finding a water-chestnut infestation at a lake when the infestation is only a few plants and manageable by hand-pulling not only saves time and resources, but also helps preserve New York’s biodiversity by preventing the infestation from growing enough to become unmanageable. This year, NYNHP has conducted a pilot GIS analysis using data from two different datasets to help guide on-the-water survey work by staff and volunteers at organizations across New York next summer. The pilot project focused on 14 key aquatic invasive species.

The Watercraft Inspection Program Application (WISPA) dataset contains:
(1) the waterbody from which a watercraft was retrieved,
(2) which invasive species are present on the watercraft (if any).

The statewide iMapInvasives platform contains data about the spatial distribution of invasive species.

Thus, it is possible to analyze both datasets simultaneously by joining these two datasets together via their spatial component. This enables a comparison of waterbodies in which watercraft are exiting a waterbody with certain aquatic invasive species attached, but no known records of the same species are documented in the iMapInvasives platform for that same waterbody. These waterbodies could thus be considered “suspicious” in their possibility of containing an infestation of the invasive species attached to the watercraft when it was retrieving from the waterbody.

These results will be made available to the NY’s eight Partnerships for Regional Invasive Species Management (PRISMs) for their use in planning 2019 field work.
