Texas Snowbell 5-Year Review

Texas snowbell The Texas snowbell was listed as endangered in 1984. More than two decades of research, monitoring, reintroduction, and searching has greatly increased our knowledge of the biology of the species, refined the distribution (a three county area - Edwards, Real, and Val Verde), and almost 1,000 plants have been located range-wide.
Herbivory, however, is still the primary threat to the continued existence of Texas snowbells throughout its range. While there has been an increase in conservation efforts by private landowners for this species, available data indicate population numbers are still not at levels that are believed necessary for long-term viability. Additionally, there are no protections in place, such as fencing of plants, to ensure long-term survival for the species. Therefore, the 5-year status review recommended no change in classification.

Devils River Minnow 5-Year Review

Devils River minnow The Devils River minnow (Dionda diaboli) , federally listed as threatened since1999, is a fish that occurs in streams tributary to the Rio Grande in Texas and northern Mexico. Its range in the U.S. is limited to Val Verde and Kinney counties, Texas.
Recent status reviews of the Devils River minnow were included in the critical habitat designation, published in August 2008, and the Devils River Minnow Recovery Plan, completed in 2005. These analyses indicate that the species remains threatened by Factor A, related to habitat loss, and Factor C, which include impacts from nonnative species. Based on this information, the 5-year review of the Devils River minnow concluded that the fish remains threatened throughout all of its range.

12-Month Finding on a Petition To List the Jollyville Plateau salamander

On December 13, 2007, The U.S. Fish and Wildlife Service published a 12-month finding on a petition to list the Jollyville Plateau salamander (Eurycea tonkawae) as an endangered species. Following a status review of the best available scientific and commercial data, we found that the threats to the continued existence of this species supported a positive finding that listing under the Endangered Species Act of 1973, as amended, is warranted. However, given the large number of pending listing actions, we found that listing the Jollyville Plateau salamander is warranted, but precluded by other listing actions of higher priority. The Service now considers this species as a candidate for listing.

Rio Grande silvery minnow 10 (j) Proposed Rule

The U.S. Fish and Wildlife Service is proposing to reintroduce the Rio Grande silvery minnow into its historic habitat in the Big Bend reach of the Rio Grande in Texas.

Rio Grande silvery minnow
Rio Grande silvery minnow

The fish would be reestablished in an area designated as a nonessential experimental population under section 10(j) of the Endangered Species Act. The Act encourages experimental reintroductions as a way to help recover a species while keeping federal regulations to a minimum. A nonessential experimental population places no burden on private landowners and water users, yet allows an opportunity to move this endangered species closer to recovery by reestablishing it in a reach of the Rio Grande where it was once common.

We welcome public comment and input on the proposal and associated Draft Environmental Assessment. Details on how to submit comments can be found in the proposed rule. In addition, a hearing on the proposal will be held October 10, at Sul Ross State University, Gallego Center, Room 129 in Alpine, Texas. The hearing begins at 7 p.m. and lasts until 8:45 p.m., with an informal question and answer session beginning at 6 p.m. Residents, state, county and local officials, landowners, farmers, recreationists and others are encouraged to attend and comment.

Critical Habitat for Comal Springs

The U.S. Fish and Wildlife Service finalized its critical habitat designation for two beetles and an amphipod, a shrimp-like crustacean. The three endangered species are the Comal Springs riffle beetle, Comal Springs dryopid beetle, and Peck's cave amphipod.

Comal Springs riffle beetle Comal Springs dryopid beetle Peck's cave amphipod

Comal Springs dryopid beetle
Peck's cave amphipod

These species are aquatic and are known to occur only in four spring systems associated with the Edwards aquifer in central (Comal and Hays Counties) Texas. All three are quite small; for example, the riffle beetle is 2 millimeters (1/8th inch) long or about as long as an uncooked spaghetti noodle is wide.

The three freshwater species share something in common with the more than 180,000 human residents of the two counties – they prefer their water unpolluted. Water quality and quantity are important concerns for the species, as well as the ecological health of the spring systems.

USFWS Section 10(a)(1)(A) Scientific Permit Requirements for Conducting Presence/Absence Surveys for Endangered Karst Invertebrates in Central Texas

The U.S. Fish and Wildlife Service (USFWS) has developed a document that outlines the USFWS process for conducting presence/absence surveys for federally-listed endangered terrestrial karst invertebrate species in Travis, Williamson, and Bexar counties, Texas, under a section 10(a)(1)(A) permit issued by the USFWS under the Endangered Species Act (Act) of 1973, as amended.

Bexar, Travis, Williamson Counties Texas Map

Section 10(a)(1)(A) permits, also referred to as recovery, enhancement of survival, or scientific permits, allow for 'take' of listed species that may or will occur while conducting research to further the recovery of a listed species. This document outlines methods to be used, information to be included in final reports, and minimum qualifications for personnel conducting presence/absence surveys for endangered karst invertebrates under a section 10(a)(1)(A) permit.

The objective of this document is to identify survey methods that will produce sound scientific information upon which to base decisions and actions for the conservation of these endangered species. Using consistent survey methodology will also allow for greater comparison and analysis of results, and thereby increase our understanding of these species and their habitat requirements. Information that relates to the effectiveness of these survey guidelines in conserving endangered karst species is welcome. The Procedures are available on the Southwest Region website.

Barton Springs Salamander Recovery Plan

The U.S. Fish and Wildlife Service is pleased to announce the availability of the approved Barton Springs Salamander (Eurycea sosorum)Recovery Plan. The Barton Springs salamander is a small amphibian known only from Barton Springs located in Zilker Park in Austin, Texas.

The salamander was listed as an endangered species in 1997 primarily due to threats from degradation of water quality and quantity.

Pecos Sunflower Recovery Plan

The final Recovery Plan for the threatened Pecos Sunflower (Helianthus paradoxus) has been approved by the U. S. Fish and Wildlife Service, New Mexico Energy, Minerals and Natural Resources Department and Texas Parks and Wildlife Department. A Fact Sheet is also available.

The Pecos sunflower occurs in seven populations; two occur in west Texas and five are located in New Mexico. Two Texas populations occur on desert springs within the same general Pecos Plain region in west Texas. Two populations occur along the Rio San Jose and one on the Rio Grande in west-central New Mexico, comprising a second distinct region. Finally, there are two distinct populations on the Pecos River in eastern New Mexico, each constituting its own region. Thus, a total of four highly disjunct regional areas contain the entire genomic and ecotypical characteristics of Pecos sunflower.

The recovery strategy is to protect and manage a significant, sustainable portion of each of the four regions’ Pecos sunflower habitats (termed “core conservation areas”) against the threat of future habitat loss and degradation, and as needed, from any other threats to the sunflower.

Land uses within these protected areas would be prescribed by management plans or voluntary deed restrictions that are sensitive to the species.


Devils River Minnow Recovery Plan

The final Recovery Plan for the threatened Devils River minnow (Dionda diaboli) has been approved by the U. S. Fish and Wildlife Service and Texas Parks and Wildlife. The Recovery Plan identifies specific, voluntary actions that will help recover the fish so it may eventually be removed from the list of threatened and endangered species. Objectives and criteria for delisting the species are spelled out. In addition, the fish’s status and current management practices are described.

A Fact Sheet and a document providing Answers to common Questions about the Devils River Minnow Recovery Plan are also available. Devils River Minnow Vignette


In a letter hand-delivered to Governor Rick Perry, officials from the U.S. Fish and Wildlife Service (USFWS) officially notified Texas that the federal government will recognize that new, optional water quality measures serve to protect certain federally listed endangered species, if voluntarily implemented in developments over the Edwards Aquifer. “After over a decade of wrestling with both state and federal regulations, the state and federal governments have come together on one set of requirements to serve two environmental goals.”
