Queensnake (Regina septemvittata)


Overview

Overview

Queensnakes (Regina septemvittata), listed as Endangered in Wisconsin, prefer clear warm-water streams and small rivers. This crayfish specialist is typically associated with moderate to fast water flows and rocky substrates. They also utilize shoreline habitats for basking. This species overwinters in crayfish burrows but also in artificial structures such as cracked bridge abutments, old dams and seawalls. Queensnakes are active from early April through October and breed mid-May through mid-June. Live young are born in August or early September. See the species guidance document for avoidance measures and management guidance from the Natural Heritage Conservation Program.

Status and Natural Heritage Inventory documented occurrences in Wisconsin

The table below provides information about the protected status - both state and federal - and the rank (S and G Ranks) for Queensnake (Regina septemvittata). See the Working List Key for more information about abbreviations. Counties shaded blue have documented occurrences for this species in the Wisconsin Natural Heritage Inventory database. The map is provided as a general reference of where occurrences of this species meet NHI data standards and is not meant as a comprehensive map of all observations.

Note: Species recently added to the NHI Working List may temporarily have blank occurrence maps.

Species guidance


Queensnake (Regina septemvittata) has very few known occurrences in the state and is of the highest priority for conservation; we encourage you to consult with your District Ecologist or an NHI Zoologist for specific recommendations for your site.

This document contains identification and life history information for Queensnake. It also describes how to screen projects for potential impact to this species, lists avoidance measures, and provides general management guidance.

Natural community (habitat) associations

The table below lists the natural communities that are associated with Queensnake. Only natural communities for which Queensnake is "high" (score=3) or "moderate" (score=2) associated are shown. See the key to association scores for complete definitions. Please see the Wildlife Action Plan to learn how this information was developed.

Ecological landscape associations

The table below lists the ecological landscape association scores for Queensnake. The scores correspond to the map (3=High, 2=Moderate, 1=Low, 0=None). For more information, please see the Wildlife Action Plan.

This map shows the probability of Queensnake occurring in each of Wisconsin's Ecological Landscapes.  Actual scores can be found in the table to the left.

Landscape-Community combinations of highest ecological priority*

Ecological priorities are the combinations of natural communities and ecological landscapes that provide Wisconsin's best opportunities to conserve important habitats for a given Species of Greatest Conservation Need. The 10 highest scoring combinations are considered ecological priorities and are listed below. More than 10 combinations are listed if multiple combinations tied for 10th place. For more information, please see the Wildlife Action Plan.


* Ecological priority score is a relative measure that is not meant for comparison between species. This score does not consider socio-economical factors that may dictate protection and/or management priorities differently than those determined solely by ecological analysis. Further, a low ecological priority score does not imply that management or preservation should not occur on a site if there are important reasons for doing so locally.

Issues/threats and conservation actions

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.
