  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

Bottom: Sicklefin Chub (Macrhybopsis meeki). Photos © David Ostendorf, used with permission. Petition Submitted to the U.S. Secretary of the Interior Acting through the U.S. Fish and Wildlife Service Petitioner: WildEarth Guardians 2590 Walnut St. Denver, Colorado 80205 (720) 443-2615 Address correspondence to: Taylor Jones [email protected] August 11, 2016 INTRODUCTION WildEarth Guardians (Guardians) respectfully requests that the Secretary of the Interior, acting through the U.S. Fish and Wildlife Service (Service) list the Sturgeon Chub (Macrhybopsis gelida) and the Sicklefin Chub (Macrhybopsis meeki) as “threatened” or “endangered” under the U.S. Endangered Species Act (ESA) (16 U.S.C. §§ 1531-1544). WildEarth Guardians also requests that the Service designate critical habitat for these species. Sicklefin and Sturgeon Chub are small fish that inhabit large, free-flowing riverine systems, characterized by swift flows, highly variable flow regimes, braided channels, high turbidity, and sand/fine gravel substrates. Both species are in decline due to severe habitat changes. In particular, the construction and operation of mainstem dams has fragmented the habitat of the Sicklefin and Sturgeon Chub. ENDANGERED SPECIES ACT AND IMPLEMENTING REGULATIONS The ESA, 16 U.S.C. §§ 1531-1544, was enacted in 1973 “to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, [and] to provide a program for the conservation of such endangered species and threatened species.” 16 U.S.C. § 1531(b).

Some authorities regard this species to be inadequately diagnosed and its taxonomic status uncertain (Burr and Warren 1986, Robison and Buchanan 1988). This has led to uncertainty regarding its distributional status in several states and speculation about misidentifications. The species is generally treated as vulnerable to imperiled in most of the upper Mississippi River basin and Ohio River drainage. It is considered secure in only a few states in the middle and lower Mississippi River basin, although records in the Gulf Slope drainages in Texas and New Mexico are thought to potentially be based on misidentifications or introductions (Etnier and Starnes 1993, Natureserve 2008, Shute 1980). S-Trend Unknown S-Trend Burr and Warren (1986) regarded this species as sporadic and rare in rivers and Comment reservoirs in western Kentucky, and sporadic in the main channels of the Mississippi and Ohio rivers.

    A Synopsis of Threatened & Endangered Species Experience Of New Century Environmental – a qualified Great Plains/Rocky Mountain environmental consulting firm New Century Environmental LLC 678 S Red Fox Lane Columbus Nebraska 68601 402-562-9155 [email protected] New Century Environmental (NCE) ecologists have conducted siting, baseline and impact assessment studies, inventory and monitoring studies for numerous regional threatened and endangered (T&E) species. We have incorporated Habitat Evaluation Procedures (HEP), stream corridor inventory, and wetland investigation methods into many of our wildlife assessments. We have been part of the Nebraska Department of Roads On-call wetland program since 2012. We have expanded distributions (wood frog, SD), found new habitats (Dakota skipper, SD) and discovered a plant in the Nebraska sand hills yet to be identified (Lehr property, Merrick County, UNL Herbarium, 2005). We have hundreds of new flora distribution records. We pride ourselves in being one of the best regional “on the ground” firms in the Midwest and elsewhere. NCE is often called upon to assess and inventory riparian habitat for restoration and monitoring programs. We use state-of-the-art methods for evaluating wetlands and riparian areas, and sensitive and rare flora and fauna associated with these habitats. We have also conducted range and upland studies to assess vegetation species composition, distribution and density as it relates to rare fauna and distribution. Our staff has worked with threatened and endangered species, small mammals, upland game birds, waterfowl, shore birds, carnivores, big game animals, reptiles, amphibians, and invertebrates. NCE uses a broad range of impact assessment tools to evaluate effects of projects on wildlife populations and terrestrial/aquatic ecosystems.
