  • The Disastrous Impacts of Trump's Border Wall on Wildlife
    a Wall in the Wild The Disastrous Impacts of Trump’s Border Wall on Wildlife Noah Greenwald, Brian Segee, Tierra Curry and Curt Bradley Center for Biological Diversity, May 2017 Saving Life on Earth Executive Summary rump’s border wall will be a deathblow to already endangered animals on both sides of the U.S.-Mexico border. This report examines the impacts of construction of that wall on threatened and endangered species along the entirety of the nearly 2,000 miles of the border between the United States and Mexico. TThe wall and concurrent border-enforcement activities are a serious human-rights disaster, but the wall will also have severe impacts on wildlife and the environment, leading to direct and indirect habitat destruction. A wall will block movement of many wildlife species, precluding genetic exchange, population rescue and movement of species in response to climate change. This may very well lead to the extinction of the jaguar, ocelot, cactus ferruginous pygmy owl and other species in the United States. To assess the impacts of the wall on imperiled species, we identified all species protected as threatened or endangered under the Endangered Species Act, or under consideration for such protection by the U.S. Fish and Wildlife Service (“candidates”), that have ranges near or crossing the border. We also determined whether any of these species have designated “critical habitat” on the border in the United States. Finally, we reviewed available literature on the impacts of the existing border wall. We found that the border wall will have disastrous impacts on our most vulnerable wildlife, including: 93 threatened, endangered and candidate species would potentially be affected by construction of a wall and related infrastructure spanning the entirety of the border, including jaguars, Mexican gray wolves and Quino checkerspot butterflies.

We’re encouraging everyone to bring a native plant, either a cutting or in a pot, to be identified and discussed at the meeting. It can be a plant you are unfamiliar with or something that you find remarkable, i.e. blooms for long periods of time or has fruit all winter or is simply gor- geous. We will take one plant at a time and discuss it with the entire group, inviting all comments about your experience with that native.

  • Draft Environmental Assessment
    DRAFT ENVIRONMENTAL ASSESSMENT ARROYO COLORADO at HARLINGEN FLOOD FLOW IMPROVEMENT PROJECT CAMERON COUNTY, TEXAS Prepared for: United States Section, International Boundary and Water Commission El Paso, Texas Prepared by: Cox|McLain Environmental Consulting, Inc. Austin, Texas May 2020 Draft Environmental Assessment and Finding of No Significant Impact Arroyo Colorado at Harlingen Flood Flow Improvement Project Cameron County, Texas Lead Agency: United States Section, International Boundary and Water Commission Preferred alternative: Expanded Vegetation Removal and Sediment Removal along the Arroyo Colorado Floodway Report Designation: Draft Environmental Assessment (EA) Abstract: The USIBWC is considering several options that would restore the full flood- conveyance capabilities to a 6.3-mile reach of Arroyo Colorado between U.S. Highway 77 Business (US 77 Business) and Cemetery Road. The Preferred Alternative would dredge sediment from the channel throughout the reach and expand existing vegetation management operations. Vegetation management currently occurs along a 3.7-mile reach of Arroyo Colorado between US 77 Business and Farm-to-Market Road 509 (FM 509). The Preferred Alternative would expand vegetation management operations to include the 2.6-mile reach from FM 509 to Cemetery Road. These actions are intended to restore Arroyo Colorado’s design flood conveyance capacity of 21,000 cubic feet per second. The Draft Environmental Assessment evaluates potential environmental impacts of the No Action Alternative and the Preferred Alternative. Two additional alternatives were considered and evaluated but were removed from consideration because they were either not effective or not feasible. Potential impacts on natural, cultural, and other resources were evaluated. A Finding of No Significant Impact has been prepared for the Preferred Alternative based on a review of the facts and analyses contained in the Environmental Assessment.

  • Finding of No Significant Impact Cattle Fever Tick Eradication Program Use of Ivermectin Corn Environmental Assessment January 2017
    Finding of No Significant Impact Cattle Fever Tick Eradication Program Use of Ivermectin Corn Environmental Assessment January 2017 In November 2016, the U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS) prepared an environmental assessment (EA) analyzing the potential environmental consequences of treating white-tailed deer with ivermectin to control tick vectors of cattle fever in Cameron, Hidalgo, Jim Wells, Kinney, Maverick, Starr, Val Verde, Webb, Willacy, and Zapata counties in South Texas. The EA that analyzed the potential impacts of this program is incorporated by reference in this document and is available on the APHIS Veterinary Services Tick Disease Information website or from: USDA-APHIS-Veterinary Services Cattle Fever Tick Eradication Program 2150 Centre Avenue Fort Collins, CO 80526 The November 2016 EA analyzed the alternatives of (1) continuing the current cattle fever tick eradication efforts in South Texas with no additional efforts to minimize the spread of ticks by white-tailed deer (no action), and (2) strategically placing ivermectin-treated corn in feeders on private and public lands in Cameron, Hidalgo, Jim Wells, Kinney, Maverick, Starr, Val Verde, Webb, Willacy, and Zapata counties (preferred alternative). On November 30, 2016, APHIS and the Texas Animal Health Commission confirmed the presence of cattle fever ticks in Live Oak County. As a result of this confirmation, APHIS is also proposing to place ivermectin-treated corn in Live Oak County. APHIS reviewed the proposal and determined that it does not raise any additional concerns that were not analyzed in the November 2016 EA. APHIS completed consultation with the U.S.

INTRODUCTION: United States (U.S.) Customs and Border Protection (CBP) plans to upgrade and lengthen four existing roads in the U.S. Border Patrol (USBP) Rio Grande City (RGC) Station’s Area of Responsibility (AOR). The Border Patrol Air and Marine Program Management Office (BPAM-PMO) within CBP has prepared an Environmental Assessment (EA). This EA addresses the proposed upgrade and construction of the four aforementioned roads and the BPAM-PMO is preparing this EA on behalf of the USBP Headquarters. CBP is the law enforcement component of the U.S. Department of Homeland Security (DHS) that is responsible for securing the border and facilitating lawful international trade and travel. USBP is the uniformed law enforcement subcomponent of CBP responsible for patrolling and securing the border between the land ports of entry. PROJECT LOCATION: The roads are located within the RGC Station’s AOR, Rio Grande Valley (RGV) Sector, in Starr County, Texas. The RGC Station’s AOR encompasses approximately 1,228 square miles, including approximately 68 miles along the U.S.-Mexico border and the Rio Grande from the Starr/Zapata County line to the Starr/Hidalgo County line. From north to south, the four road segments are named Mouth of River to Chapeno Hard Top, Chapeno USIBWC Gate to Salineno, Salineno to Enron, and 19-20 Area to Fronton Fishing, and all of these segments are located south of Falcon International Reservoir (Falcon Lake), generally parallel to the Rio Grande.

  • Texas Ayenia) (Ayenia Limitaris)
    DRAFT RECOVERY PLAN FOR THE TAMAULIPAN KIDNEYPETAL (TEXAS AYENIA) (AYENIA LIMITARIS) Southwest Region U.S. Fish and Wildlife Service Albuquerque, NM Approved: /s/Joy E. Nicholopoulos, Acting 06/03/2014 Regional Director, Southwest Region Date: U.S. Fish and Wildlife Service Disclaimer The Endangered Species Act of 1973 (ESA), as amended (16 U.S.C. 1531 et seq.), requires the development of recovery plans for listed species, unless such a plan would not promote the conservation of a particular species. Recovery plans delineate such reasonable actions as may be necessary, based upon the best scientific and commercial data available, for the conservation and survival of listed species. Plans are published by the U.S. Fish and Wildlife Service (FWS), sometimes prepared with the assistance of recovery teams, contractors, State agencies and others. Recovery plans do not necessarily represent the views, official positions or approval of any individuals or agencies involved in the plan formulation, other than FWS. They represent the official position of FWS only after they have been signed by the Regional Director. Recovery plans are guidance and planning documents only; identification of an action to be implemented by any public or private party does not create a legal obligation beyond existing legal requirements. Nothing in this plan should be construed as a commitment or requirement that any Federal agency obligate or pay funds in any one fiscal year in excess of appropriations made by Congress for that fiscal year in contravention of the Anti-Deficiency Act, 31 U.S.C. 1341, or any other law or regulation. Approved recovery plans are subject to modification as dictated by new information, changes in species status, and the completion of recovery actions.
