The timber rattlesnake (Crotalus horridus) was historically widespread throughout eastern North America but now persist in four New England states in small, isolated populations. The goal of this study was 1) assess the population viability of New England timber rattlesnake populations, 2), describe the population genetics structure of timber rattlesnakes in New England and provide recommendations for genetic management and monitoring, and 3) develop a standardized protocol for...

Since 2010, the U.S. Fish and Wildlife Service (USFWS) has received numerous listing petitions for potentially imperiled species. More than 25% of the species on the complete list occur in at least one state of the Northeast Association of Fish and Wildlife Agencies (NEAFWA). Many of these species have been included as Species of Greatest Conservation Need in one or more Wildlife Action Plans developed by NEAFWA state members.

 A preliminary evaluation by state fish and wildlife...

This study uses genetic data to identify genetic diversity across the study area (Maine to Virginia), to identify the number of populations in the study area and determine the success of genetic assignment of individuals to sites of origin. Tissue samples were collected as blood, tail tips, toenails and shell shavings or scutes from 1,895 Wood Turtles. Tissue samples were genotyped at 16 microsatellite markers for 1,244 individuals. Genetic data were analyzed for genetic diversity, genetic...

Land snails are an integral part of native habitats throughout the Northeast, playing important roles in cycling organic material and creating soil, moving energy and nutrients in food chains, and hosting major wildlife parasites. This project informs the important conservation needs and opportunities associated with 245 land snail species of the northeastern United States, many of which are listed as Species of Greatest Conservation Need or Data Deficient by many of the 14 State Fish and...

The goal of this project is to facilitate and support regional collaboration on shared priorities identified in state wildlife action plans by compiling key information from the remaining NEAFWA Wildlife Action Plans in a database with simple query and report functions. This effort will allow identification of regional patterns and priorities of species of greatest conservation need, habitats, threats and conservation actions.

​The purpose of the database tool is to capture, organize...

In support of State Fish and Wildlife Agencies identifying regional priorities through access to 14 Northeast (NE) State Wildlife Action Plan (SWAP) data

The objectives of this project were to:  

  • To compile key information from the 14 NE SWAPs in a streamlined database and provide state agencies (and their partners) with easy access to this information through simple queries and reports. 
  • To allow identification of region-wide patterns and priorities based on a...

Fourteen species of wetland-inhabiting butterfly species of Greatest Coservation Need (SGCN) status were surveyed in 2016 and 2017 at multiple sites across four states - Maryland, New Jersey, Pennsylvania and West Virginia. Survery data was used to evaluate the status of each species in all states where they occurred as well as refine the distribution data for each species across the region. All data points were mapped in ArcGIS and used to model species distribution in terms of both habitat...

The relationships between woodrat population dynamics and abiotic forest conditions and biotic pathogen loads have been speculated, but there have been few long-term studies to address these speculations. Our two-tiered study that will: Objective 1. Determine interactions between woodrat populations and forest dynamics using dendrochronology, mast production data, and inventories; Objective 2. (a) Determine incidence of raccoon roundworm (Baylisascaris procyonis) parasite load in raccoon...

Dam removal and fish passage projects are a critical component of anadromous alewife restoration, reconnecting runs to prime spawning habitat in coastal lakes. However, landlocked alewife populations have become established in many coastal New England lakes. The effects of landlocked alewives on anadromous alewife restoration are currently unknown. We investigated the effects of landlocked alewife presence on anadromous alewife restoration in Rogers Lake, which once hosted one of the largest...

To accomplish the project objective of collaboratively developing clear conservation goals and strategies for action in the northeast region this proposal outlines three major components:

  1. A thorough review of species, habitats, threats, and actions identified in the 14 Wildlife Action Plans produced by the northeastern states and the District of Columbia
  2. When requested, provide assistance to state agencies in determining regional species and habitats of greatest...
