2018 Invasive Species Categorization

This categorization of Invasive Species in the Catskill Regional Invasive Species Partnership (CRISP) attempts to prioritize invasive species based on the ability of CRISP to perform prevention, early detection and control efforts for these invasive species based on the species invasiveness (according to NYS ranking evaluation) and distribution (according to iMapInvasives and expert knowledge).

The Invasive Species Tiers were developed between New York State iMapInvasive staff and the Partnership for Regional Invasive Species Management Coordinators. Each very high, or high, impact invasive species is assigned to the following tiers:

 

Tier 1 Early Detection/Prevention

Highest level of early detection survey efforts. Should conduct detection surveys and assign to appropriate Tier if detected.

1a) Inside Buffer 

(within 100 miles of PRISM), but not in PRISM

1b) Outside PRISM and Buffer

but close (Eastern North America)

1c) Far outside PRISM and Buffer 

(not in Eastern North America), but introduction pathway exists.

Tier 2 Eradication

Highest level of early detection response efforts. High impact species with low enough abundance and suitable treatment method available to make eradication feasible within the PRISM. Need delineation surveys to determine extent.

Tier 3 Containment

Target strategic management to slow the spread (e.g. remove outlying and border populations), as likely too widespread for eradication, but many surrounding regions could be at risk if left unattended. Use IPMDAT for plants. Possible eradication candidate only if adequate resources and effective control methods available.

Tier 4 Local Control

Eradication from PRISM not feasible; focus on localized management over time to contain, exclude, or suppress to protect high-priority resources like rare species or recreation assets.  Be strategic when deciding if/where to control.

Tier 5 Monitor

Species that need more research, mapping, and monitoring to understand their invasiveness.  This includes naturalized species and cultivated-only species that are known to be invasive in other regions but are not yet invasive here. Invasiveness may change with environmental or genetic changes.  Should monitor populations on a regular basis to see if they are starting to become invasive and assign to appropriate Tier if invasive infestations detected.

The following table summarize the species according to NYS Rank. Species rank represents assessment of that species’ invasiveness in NYS.

VH = Very High, H = High, M = Moderate, L = Low, I = Insignificant, U = Unknown.

 
 

Tier 1 Species:

are not known to occur within the PRISM boundary but represent a high potential for spread and establishment if introduced. Goals for these species are Early Detection/Prevention.

Tier 3 Species:


are species which are too high abundance within the PRISM boundary for Eradication to be likely. Management goal is Containment, unless particularly effective control methods or adequate funding sources become available. The IPMDAT tool should be used to assess individual populations for management.
