The Whooping Crane (Grus americana; WHCR) is a large, long-lived bird endemic to North America. The remnant population migrates between Aransas National Wildlife Refuge, USA, and Wood Buffalo National Park, Canada (AWBP), and has recovered from a nadir of 15-16 birds in 1941 to ~540 birds in 2022. Two ongoing reintroduction efforts in Louisiana and the Eastern Flyway together total ~150 birds. Evidence indicates the U.S. Fish and Wildlife Service (USFWS) is strongly considering downlisting the species from an endangered to a threatened status under the Endangered Species Act (ESA). We examined the current status of the WHCR through the …


The U.S. Endangered Species Act And Agency Discretion: The Role Of Public Commenting During The Rulemaking Process, Krista Helmstadter Lyons Dec 2022

The U.S. Endangered Species Act And Agency Discretion: The Role Of Public Commenting During The Rulemaking Process, Krista Helmstadter Lyons

Boise State University Theses and Dissertations

The most recent International Union for Conservation of Nature (IUCN) Red List classifies 40,084 out of the 142,577 evaluated species as threatened with extinction, with 1,962 of those species identified in the United States. The U.S. Endangered Species Act (ESA) was enacted in 1973 to protect and recover threatened and endangered species from extinction. The ESA federal listing process can be lengthy and arduous, taking years for a species to be proposed for listing. During the process the U.S. Fish and Wildlife Service (FWS) seeks comments from the public and peer reviewers on the proposed rule. Previous research debates the …


Understanding Stakeholder Attitudes And Involvement In Habitat Conservation Plans And The Endangered Species Act, Kyle Andrew Rodgers Dec 2016

Understanding Stakeholder Attitudes And Involvement In Habitat Conservation Plans And The Endangered Species Act, Kyle Andrew Rodgers

Masters Theses

The Endangered Species Act (ESA), established in 1973, was a landmark piece of environmental legislation and remains the standard for endangered species conservation. Implementation of the ESA has often been framed as pitting economic development against species conservation, inciting passions for and against endangered species conservation. The strength of opposing public opinions is highlighted by high-profile controversies such as those around the snail darter, northern spotted owl and the greater sage grouse. In an attempt to reduce conflict, the US Fish and Wildlife Service (USFWS) increasingly seeks to utilize collaborative, stakeholder-based processes that address stakeholder interests, attitudes, and values.

Slides: Flpma In Its Historical Context, John D. Leshy Oct 2016

Slides: Flpma In Its Historical Context, John D. Leshy

FLPMA Turns 40 (October 21)

Presenter: John D. Leshy, Sunderland Distinguished Professor of Law Emeritus, U.C. Hastings College of the Law

36 slides

This session traces the history of FLPMA including, among other things, its legislative, administrative, and historical antecedents, including for example, the Public Land Law Review Commission’s 1970 report, One Third of Our Nation’s Lands. It then considers FLPMA’s unique public lands policies and requirements and how they are reflected in the BLM’s management of public lands today.

Geographic Variation, Null Hypotheses, And Subspecies Limits In The California Gnatcatcher: A Response To Mccormack And Maley, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda Dec 2015

Geographic Variation, Null Hypotheses, And Subspecies Limits In The California Gnatcatcher: A Response To Mccormack And Maley, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda

School of Natural Resources: Faculty Publications

We interpreted the results of nuclear DNA sequencing to be inconsistent with the recognition of California Gnatcatcher (Polioptila californica) subspecies. McCormack and Maley (2015) suggested that our data did support 2 taxa, one of which was P. c. californica, listed as Threatened under the Endangered Species Act (ESA). We summarize here how 2 sets of researchers with access to the same data reached different conclusions by including different analyses. We included the southern subspecies’ boundary from the taxonomy of Atwood (1991), the taxonomic basis for the ESA listing, which resulted in an Analysis of Molecular Variance that …

Evaluating Recreationists’ Awareness And Attitudes Toward Piping Plovers (Charadrius Melodus) At Lake Mcconaughy, Nebraska, Usa, Joel G. Jorgensen, Mary Bomberger Brown Jan 2015

Evaluating Recreationists’ Awareness And Attitudes Toward Piping Plovers (Charadrius Melodus) At Lake Mcconaughy, Nebraska, Usa, Joel G. Jorgensen, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Piping plovers (Charadrius melodus) are shorebirds federally protected by the U.S. Endangered Species Act that often nest on beaches in proximity to human recreation. We evaluated whether awareness of piping plovers and their legally protected status and attitudes toward species management varied between groups of recreationists at Lake McConaughy, Keith County, Nebraska, USA. Awareness of piping plovers varied primarily by the respondents’ number of annual visits to Lake McConaughy; the respondents’ age, sex, or location of primary residence had less influence. Recreationists with increased awareness of piping plovers and their protected status did not have more favorable attitudes toward plovers …


Phylogeography Of The California Gnatcatcher (Polioptila Californica) Using Multilocus Dna Sequences And Ecological Niche Modeling: Implications For Conservation, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda Apr 2013

Phylogeography Of The California Gnatcatcher (Polioptila Californica) Using Multilocus Dna Sequences And Ecological Niche Modeling: Implications For Conservation, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda

School of Natural Resources: Faculty Publications

An important step in conservation is to identify whether threatened populations are evolutionarily discrete and significant to the species. A prior mitochondrial DNA (mtDNA) phylogeographic study of the California Gnatcatcher (Polioptila californica) revealed no geographic structure and, thus, did not support the subspecies validity of the threatened coastal California Gnatcatcher (P. c. californica). The U.S. Fish and Wildlife Service concluded that mtDNA data alone were insufficient to test subspecies taxonomy. We sequenced eight nuclear loci to search for historically discrete groupings that might have been missed by the mtDNA study (which we confirmed with new ND2 …
