Prioritizing Invasive Species Management Efforts in New York State
Jennifer Dean, in collaboration with NYS DEC and SUNY ESF, leads spatial prioritization efforts to focus on invasive species detection and management in protected areas, high conservation value zones, recreation destinations, and high-risk areas. Through innovative mapping resources and stakeholder feedback, the team aims to assist natural resource managers in prioritizing resources for early detection surveys and control strategies based on conservation value and risk of spread. Detailed components include ecological significance, protected or natural areas, and the risk of spread factors.

Spatial Prioritization Invasive Species Early Detection and Management Efforts Jennifer Dean jennifer.dean@dec.ny.gov
Where to focus our invasive species efforts? Protected areas High conservation value Recreation destinations High risk areas Areas NOT heavily invaded
Our mission is to facilitate conservation of New York's biodiversity by providing comprehensive information and scientific expertise on rare species and natural ecosystems to resource managers and other conservation partners. Partnership between NYS DEC and SUNY ESF Invasive Species Database Program: Providing invasive species mapping resources for NYS
Spatial Prioritization Maps for Invasive Species Spatial Prioritization Maps for Invasive Species GOAL - Help Natural Resource Managers prioritize where to focus resources for Early Detection surveys and invasive species control by coupling conservation value and risk of spread. Basic Steps: 1) Compiled spatial data on factors influencing invasive control decisions Used layers with statewide coverage and fine scale resolution 2) Created new synthesis layers Driven by stakeholder feedback and expected uses Risk of Spread Conservation value Protection Status

Prioritization map component scores Prioritization map component scores ECOLOGICAL SIGNIFICANCE Layer Description Orig. Max New Max Weight Natural Heritage element occurrences, scored based on EO quality, accuracy, and rarity. Square root transformed the highly skewed data. Element Occurance Data 46 1 50 Mussels Number of predicted mussel species according to the Freshwater Blueprint. 17 1 5 Biological Assessment Profile- measure of stream health based on invertebrate diversity and abundance. BAP 9.45 1 5 Element Distribution Models Habitat predicted to be suitable for rare species according to Natural Heritage Element Distribution Models. 34 1 30 90 PROTECTED OR NATURAL/LIFTING FACTORS Layer Description Orig. Max New Max Weight All polygons in the New York Protected Areas Database were included. To provide a measure of relative habitat quality, each polygon was scored them by evaluating the average Natural Heritage Biodiversity Index score for each unique property name. NYPAD 10 1 15 Taken from the 2011 NLCD. Points given to land where "Cover Type" is equal to "Natural Cover . Natural Land 1 1 5 20 RISK OF SPREAD Layer Description Orig.

LCA 3820 1 35 Data obtained from NYS GIS Clearinghouse DEC Trails, converted from KML to points. Calculated Euclidean distance to trails. Max distance 1000 meters.

Comprehensive Score: Comprehensive Score: Ecological Significance + Protected or Natural + Risk Ecological Significance + Protected or Natural + Risk Ecological Significance Protected or Natural Risk of Spread 56% 13% 31% Comprehensive Score Areas of high conservation value with high risk of new invasions and dispersal
Using the prioritization map models Using the prioritization map models Working at different scales Working at different scales Example use Regional Scale Where can PRISM efforts target high value natural areas prone to new invasions and dispersal? Example use State Scale Where along major roads could DOT prioritize resources for invasive species control to maximize conservation values? Example use Local/Park Scale A big crew of volunteers is coming tomorrow! Which easily accessible areas would benefit from an invasive plant removal project?

Accessing the maps Within iMapInvasives As raster layers Need an iMap account Level 2 and up Request a login account: www.nyimapinvasives.org Map layers available to those with ArcGIS as tif files Email: imapinvasives@dec.ny.gov
Stakeholder Feedback Stakeholder Feedback Do the hot spots of the Comprehensive Score map correspond to areas you think should be highlighted in your region? Do the hot spots of the Ecological Significance map correspond to areas you think should be highlighted in your region? Examples of ways your organization/region would use these maps (or combinations of) to help make decisions.
