Prioritizing Odonata for Conservation Action in the Northeastern USA
APPLIED ODONATOLOGY Prioritizing Odonata for conservation action in the northeastern USA Erin L. White1,4, Pamela D. Hunt2,5, Matthew D. Schlesinger1,6, Jeffrey D. Corser1,7, and Phillip G. deMaynadier3,8 1New York Natural Heritage Program, State University of New York College of Environmental Science and Forestry, 625 Broadway 5th Floor, Albany, New York 12233-4757 USA 2Audubon Society of New Hampshire, 84 Silk Farm Road, Concord, New Hampshire 03301 USA 3Maine Department of Inland Fisheries and Wildlife, 650 State Street, Bangor, Maine 04401 USA Abstract: Odonata are valuable biological indicators of freshwater ecosystem integrity and climate change, and the northeastern USA (Virginia to Maine) is a hotspot of odonate diversity and a region of historical and grow- ing threats to freshwater ecosystems. This duality highlights the urgency of developing a comprehensive conser- vation assessment of the region’s 228 resident odonate species. We offer a prioritization framework modified from NatureServe’s method for assessing conservation status ranks by assigning a single regional vulnerability metric (R-rank) reflecting each species’ degree of relative extinction risk in the northeastern USA. We calculated the R-rank based on 3 rarity factors (range extent, area of occupancy, and habitat specificity), 1 threat factor (vulnerability of occupied habitats), and 1 trend factor (relative change in range size). We combine this R-rank with the degree of endemicity (% of the species’ USA and Canadian range that falls within the region) as a proxy for regional responsibility, thereby deriving a list of species of combined vulnerability and regional management responsibility. Overall, 18% of the region’s odonate fauna is imperiled (R1 and R2), and peatlands, low-gradient streams and seeps, high-gradient headwaters, and larger rivers that harbor a disproportionate number of these species should be considered as priority habitat types for conservation. -
Critical Species of Odonata in North America
---Guardians of the watershed. Global status of dragonflies: critical species, threat and conservation --- Critical species of Odonata in North America Sidney W. Dunkle Biology Dept., Collin County Community College, Spring Creek Campus, Plano, Texas, USA 75074. <sdunkle®ccccd.edu> Key words: Odonata, dragonfly, IUCN, critical species, conservation, North America. ABSTRACT Of the approximately 439 species of Odonata known from North America, north of Mexico, comments on 25 species (6%) of conservation concern are given. Species deemed to be under the most threat are Ischnura gemina, Gomphus sandrius, Ophiogomphus australis, Stylurus potulentus, and Libellula jesseana. Two other species not under threat, Neurocordulia michaeli and Somatochlora brevicincta, are briefly discussed because of their conservation interest. Some geographical clumping of species under threat is discussed, in southeastern Arizona, coastal New England, and the central Gulf of Mexico Coast. REGIONAL DEFINITION Canada and the United States north of the Mexican border, including Alaska but not Hawaii. This is the Nearctic biogeographic realm exclusive of the Mexican Plateau. STATE OF THE ART The Nearctic Odonata fauna includes approximately 130 species of Zygoptera and 309 of Anisoptera. North Americans are fortunate in having excellent identification guides for both Zygoptera (Westfall & May 1996) and Anisoptera (Westfall & Tennessen 1996; Needham et al. 2000), supplemented by several field guides such as Dunkle (2000). The recent proliferation of field guides and popular magazine articles, along with the activities of the Dragonfly Society of the Americas and numerous websites, has resulted in many more people looking for odonates in North America. The general result has been the location of many more localities, even for rare species. -
New Hampshire Dragonfly Survey Final Report
The New Hampshire Dragonfly Survey: A Final Report Pamela D. Hunt, Ph.D. New Hampshire Audubon March 2012 Executive Summary The New Hampshire Dragonfly Survey (NHDS) was a five year effort (2007-2011) to document the distributions of all species of dragonflies and damselflies (insect order Odonata) in the state. The NHDS was a partnership among the New Hampshire Department of Fish and Game (Nongame and Endangered Wildlife Program), New Hampshire Audubon, and the University of New Hampshire Cooperative Extension. In addition to documenting distribution, the NHDS had a specific focus on collecting data on species of potential conservation concern and their habitats. Core funding was provided through State Wildlife Grants to the New Hampshire Fish and Game Department. The project relied extensively on the volunteer efforts of citizen scientists, who were trained at one of 12 workshops held during the first four years of the project. Of approximately 240 such trainees, 60 went on to contribute data to the project, with significant data submitted by another 35 observers with prior experience. Roughly 50 people, including both trained and experienced observers, collected smaller amounts of incidental data. Over the five years, volunteers contributed a minimum of 6400 hours and 27,000 miles. Separate funding facilitated targeted surveys along the Merrimack and Lamprey rivers and at eight of New Hampshire Audubon’s wildlife sanctuaries. A total of 18,248 vouchered records were submitted to the NHDS. These represent 157 of the 164 species ever reported for the state, and included records of four species not previously known to occur in New Hampshire. -

Maine's List of Endangered and Threatened Species
Recommended Changes to Maine’s List of Endangered and Threatened Species January 2, 2007 Recommended Changes to Maine’s Endangered and Threatened Species List January 2, 2007 INTRODUCTION The Maine Department of Inland Fisheries and Wildlife (MDIFW) is currently in the proc- ess of recommending updates to the State’s Endangered and Threatened Species list. These proposed changes include a) 14 new listings, b) 1 delisting, c) a change of status from Endangered to Threatened for 1 currently listed species, and d) adding the qualifier “breeding population only” to 2 species currently listed as Endangered. If approved by the Legislature, this will be the first update to Maine’s list since 1997. The current listing process essentially began with completion of Maine’s Comprehensive Wildlife Conservation Strategy in September 2005 (available on the MDIFW website http:// www.state.me.us/ifw/wildlife/compwildlifestrategy/index.htm). Preparation of this docu- ment required a comprehensive review of most of Maine’s fish and wildlife species, thus providing impetus to this listing process. The official listing process began in November 2005 with establishment of committees or- ganized by species group (i.e. amphibians and reptiles, birds, fish, invertebrates, and mammals). These committees were comprised primarily of MDIFW species experts, who reviewed candidate species under their purview to determine whether a species qualified for listing as Endangered or Threatened under the Maine Endangered Species Act. Each determination was guided by established, scientific criteria and listing guidelines based on mandates of the Act and related rules. Initial recommendations, along with supporting documentation, were then submitted to species experts outside the Department for review and input. -

Last updated February 7, 2008 Approved by the NHES Advisory Committee, March 13, 2008 Introduction ▪ What is the purpose of this document? This document describes the basis, criteria, and procedure with which decisions are made regarding the listing and delisting of Endangered, Threatened, and Special Concern species in Massachusetts. Listing is based on the Massachusetts Endangered Species Act (MESA) statute (see Appendix C) and its implementing regulations (see Appendix D). ▪ What is the basis for the guidelines? The guidelines build upon listing policy as administered since implementation of the MESA regulations in 1991, and draw upon other major systems used in the assessment of extinction risk, particularly the systems of NatureServe (Master et al. 2007) and the International Union for the Conservation of Nature (IUCN 2001). Concordance with these and other major systems is sought through the use of three main criteria in the assessment of extinction risk: rarity, trend, and threat. -

New York Natural Heritage Program, Albany, NY. ii Executive Summary Odonates are valuable biological indicators of freshwater ecosystem integrity and climate change. Approximately 18% of odonates in the US are considered rare and vulnerable to extirpation or extinction. Northeastern North America hosts a rich and ancient odonate fauna, especially for a temperate region. Recognition of northeastern North America as both a hotspot of odonate diversity, and a region of historical and growing threats to freshwater ecosystems, highlights the urgency of developing a comprehensive conservation assessment of the Northeast’s resident odonate species. Here, we develop and apply a prioritization framework for 228 species of dragonflies and damselflies occurring in the northeastern US (Virginia to Maine). Specifically, we offer a modified version of NatureServe’s methodology for assessing conservation status ranks by assigning a single, regional vulnerability metric (R-rank) reflecting each species’ degree of relative extinction risk in the northeastern US. -
Wisconsin Wildlife Action Plan 3.5 Invertebrate Species of Greatest Conservation Need
Wisconsin Wildlife Action Plan 3.5 Invertebrate Species of Greatest Conservation Need 3.5 Invertebrate Species of Greatest Conservation Need This is an overview of Wisconsin’s invertebrate Species of Greatest Conservation Need (SGCN) and their associations with Natural Communities and Ecological Landscapes. This section also identifies invertebrate species that are not classified as SGCN, but are classified as BasicSINS (species with information needs), RankingSINS, or species that had sufficient information to assess them with confidence and did not meet the SGCN criteria (e.g., ranked S4 or S5, ranked S3G5 or S3S4G5, or did not meet the additional criteria considered after assessing S/G-Ranks). See Section 2.6 for more explanation on ranking and SINS. The issues, challenges and conservation actions that will be important for most or all invertebrate SGCN over the next ten years are presented in the second half of this section along with those applicable to one or a few invertebrate species. The discussion of the issues and challenges facing invertebrate SGCN and their habitat, and the conservation actions that address them, follows nomenclature developed by the Open Standards for the Practice of Conservation.1 The Open Standards classification for Conservation Actions, with some modification for circumstances particular to Wisconsin, is presented in Appendix 2.1 at the end of Section 2. When dealing with invertebrates, it is often necessary to reconcile conflicts in the scientific nomenclature used by different researchers. Such conflicts result from advances in the description and documentation of previously undescribed invertebrate species and a changing understanding of evolutionary relationships. To ensure the most up-to-date taxonomic labels, scientific names from the Tree of Life Web Project (The University of Arizona 2004) were used. -

FLETCHERI Stephen Ross 1 and Mark F. O'Brien 2 ABSTRACT Williamsonia lintneri is newly recorded for Michigan, and additional Michigan sites are given for W fletcheri. Both species appear to be bog/fen obligate inhabitants, and adults may appear as early as late April in Michi gan. In addition, the North American distributions of both species are sum marized. The genus Williamsonia contains two bog-obligate corduliid species found primarily in eastern North America. Williamsonia fletcheri Williamson (the ebony bog-haunter), known from Manitoba eastward (Walker and Corbet 1975), and Williamsonia lintneri Hagen (the ringed bog-haunter), formerly characterized as a NE North American species, with records from New Eng land and the Atlantic Provinces of Canada (Howe 1923, Carpenter, 1993, and summary below). -
Ringed Boghaunter Williamsonia Lintneri
Appendix A: Insects Ringed Boghaunter Williamsonia lintneri Federal Listing N/A State Listing E Global Rank G3 State Rank S2 Regional Status High Photo by Pamela Hunt Justification (Reason for Concern in NH) Considered “highly vulnerable” by the Northeastern Odonata Conservation Assessment (White et al 2014), because of its restricted range, specialized habitat, and historic loss of peripheral populations in NY and NJ. Most of the population occurs in the heavily developed coastal plain from Maine to Connecticut, and the species is listed as threatened or endangered in all states where it occurs. Distribution Most of the global population occurs from southwestern Maine to eastern Connecticut, with disjunct populations in Wisconsin and Michigan. There are also historic records from northern New Jersey and Albany, NY. Ringed Boghaunters have been documented at roughly 15 sites in New Hampshire, all in the southeast portion of the state in a band from Strafford and Durham to Amherst and South Hampton. Extensive field work in 2007‐2011 doubled the number of locations with this species, although it has not been detected at some sites for several years. Breeding has not been conclusively shown at all sites, but is suspected at most through a combination of repeated detection or relatively high abundance. Habitat Ringed Boghaunters are restricted to wetland habitats containing extensive floating or suspended Sphagnum. These are generally acidic fens (deMaynadier and Carlson 1998, Lundgren 1999), which are weakly minerotrophic peatlands that receive some nutrients from groundwater springs, seeps, and streams. Vegetation can be highly variable, including shrubby basins, dwarf shrub fens, graminoid‐dominated fens (usually sedges), and Sphagnum‐filled pools or basins (Lundgren 1999). -
