  • 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.

  • The Taxonomic Report of the INTERNATIONAL LEPIDOPTERA SURVEY
    Volume 7 1 February 2010 Number 3 The Taxonomic Report OF THE INTERNATIONAL LEPIDOPTERA SURVEY TIPS ON COLLECTING AND REARING IMMATURES OF 375 BUTTERFLY AND SKIPPER TAXA JACQUE WOLFE 459 East 2700 South Apt 16, Salt Lake City, UT 84115 JACK HARRY 47 San Rafael Court, West Jordan, UT 84088 TODD STOUT 1 1456 North General Drive, Salt Lake City, UT 84116 ABSTRACT: Rearing techniques are discussed for 375 different butterfly and skipper taxa from Utah and beyond. Additional keywords: ova, larvae, pupae, over wintering, obtaining and caring for immatures INTRODUCTION The authors of this paper, Jacque Wolfe, Jack Harry, and Todd Stout, with contributions from Dale Nielson have over 100 years combined experience collecting and rearing butterflies. This publication includes natural and lab host plants. We hope that this information will help you avoid some of the mistakes and losses we have experienced. We also hope that this publication will encourage someone who has only collected adults to give rearing a try. For those new to rearing we encourage starting small. Not only can rearing provide perfect specimens but also provide knowledge regarding the life histories of butterflies, which includes how to find caterpillars or how to entice live females to lay eggs. The advantages justify the time and effort it requires. Another advantage of rearing is that some species, like Papilio indra and Megathymus species, are difficult to collect as adults. Therefor, rearing them can be much easier. For example, collecting larvae or netting a single live female can result in obtaining a nice series of perfect specimens.

Sacramento Fish and Wildlife Field Office U.S. Fish and Wildlife Service Sacramento, California February 2010 5-YEAR REVIEW San Bruno Elfin Butterfly (Callophrys mossii bayensis) and Mission blue butterfly (Icaricia icarioides missionensis) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed.

  • Arthropod Community Response to Nitrogen Deposition Eliza Hernández Research Mentor: Erin Questad, Ph.D
    Arthropod community response to nitrogen deposition Eliza Hernández Research Mentor: Erin Questad, Ph.D. California State Polytechnic University, Pomona Abstract Insects play key ecological roles by providing services such as pollination and decomposition. Anthropogenic activity threatens the conservation of beneficial insects and is partly responsible for the observed decline in insect diversity. Nitrogen deposition, a human- accelerated process, poses a threat to insect diversity and thus, their valuable services. Increased N levels have been found to increase insect abundances yet decrease their species richness. The primary focus of this project was to determine the effects of N on the taxonomic richness, diversity, and evenness of insects and other arthropods in a managed grassland experiment at the South Coast Research & Extension Center in Irvine, California. I sampled from ten experimental grassland plots, five of which were treated with elevated levels of N and the other five were exposed to ambient levels of N. The plots contained grasses typical of Southern California grasslands, such as the California native grass, Stipa pulchra, and the invasive grass, Bromus hordeaceus. To sample soil and litter-dwelling arthropods throughout the growing season, each plot contained two pitfall traps. Arthropods were identified to the family taxonomic level. I expected to find greater arthropod richness, diversity, and evenness in the plots with ambient N compared to elevated N. However, this project indicates that fertilized plots host a greater richness of soil and litter-dwelling arthropod groups. Introduction Anthropogenic N deposition has more than doubled inputs of N to terrestrial ecosystems worldwide via the transformation of unreactive atmospheric N into biologically available forms on land (Vitousek et al., 1997).

    Ken H. Osborne 6675 Avenue Juan Diaz, Riverside, CA, 92509 May 22, 2015 Mr. Dennis Campbell County of San Diego Planning and Development Services 5510 Overland Avenue, Suite 110 San Diego, California 92123 Subject: Draft Environmental Impact Report, General Plan Amendment, and Specific Plan Amendment for Otay Ranch Village 13/Resort Village Impacts on the Federally Endangered Quino Checkerspot Butterfly. Dear Mr. Campbell Endangered Habitats League has asked that I review the proposed Otay Ranch Village 13/Resort Village project in its various alternative forms as described in the March 2015 draft Environmental Impact Report (DEIR), in light of any potential impacts that it (they) may have on the resident population of federally endangered Quino Checkerspot Butterfly (Quino) on the project site. I am a known biologist with some depth of understanding in the biology, ecology, and conservation of this endangered species (Appendix). To this end, I will begin by providing my overall prognosis of implications for Quino with this project and evidence supporting my prognosis including detailed explanation of mechanisms of impact and illustration of example populations extirpated in the wake of similar developments. Although briefed in my introductory comments, a detailed description of Quino biology and ecology will be provided in the appendix as foundational material. After reviewing the DEIR, I have quickly and easily come to the conclusion that this project is not compatible with Quino conservation. Although I can’t go so far to say that this development would, by itself, cause the global extinction of Quino, it would certainly significantly contribute to that end. Even with Alternative G, it’s apparently minimal development footprint gives me concern.

  • Field Studies and Conservation Planning for the Endangered Laguna Mountains Skipper Pyrgus Ruralis Lagunae
    f"" ,.... ~'.' .. ~ .,;. FINAL REPORT 1998 Field studies and Conservation planning for the endangered Laguna Mountains Skipper Pyrgus ruralis lagunae Rudi Mattoni Travis Longcore URBAN WILDLANDS GROUP DEPARTMENT OF GEOGRAPHY UNIVERSITY OF CALIFORNIA,: LOS ANGELES 1255 Bunche Hall Los Angeles, California 90095-1524 (310) 825 3019 E-mail: [email protected] or [email protected] October 6, 1998 -1- , . Introduction During 1997 and 1998 we conducted an exploratory program to elucidate natural history and demographic characteristics of the endangered Laguna Mountains Skipper (LMS) in order to outline a sound conservation plan. The species was apparently historically found throughout the wet subalpine meadows and forest openings of the Laguna, Palomar, and possibly Cuyamaca Mountains. Today it appears restricted to a few sites in the Palomar and Laguna Mountains where its populations have declined. Our assessment of decline is anecdotal, based on past collecting records and recollections of a few collectors, but unquestionably accurate in overall outline. Because the decline of the LMS, in parallel with most increasingly rare species, correlates with the general expansion of human enterprises, its ultimate conservation will require some management. Before a meaningful management plan can be designed, however, it is first necessary to understand the naturalhistory of the target species and its place in the biotic community. Such data are virtually non-existent ter the LMS.- We attempt to answer the following questions, which we briefly state with the results obtained, followed by our tentative management conclusions and plans for continued f~Jure efforts. 1. How many annual generations are there for the LMS? 2. What are the life history characteristics of the LMS that are important in defining its distribution and abundance? 3.

Whether we have viewed the coasts of British Columbia or Cape Breton, experienced the beauty of the Arctic tundra, paddled on rivers through our sweeping boreal forests, heard the wind in the prairies, watched caribou swim the rivers of northern Labrador, or searched for song birds in the hardwood forests of south eastern Canada, we all call Canada our home and native land. Perhaps because Canada’s landscapes are extensive and cover a broad range of diverse natural systems, it is easy for us to assume the health of our important natural spaces and the species they contain. Our country seems so vast compared to the number of Canadians that it is difficult for us to imagine humans could have any lasting effect on nature. Yet emerging science demonstrates that our natural systems and the species they contain are increas- ingly at risk. While the story is by no means complete, key indicator species demonstrate that Canada’s natural legacy is under pressure from a number of sources, such as the conversion of lands for human uses, the release of toxic chemicals, the introduction of new, invasive species or the further spread of natural pests, and a rapidly changing climate. These changes are hitting home and, with the globalization and expansion of human activities, it is clear the pace of change is accelerating. While their flights of fancy may seem insignificant, butterflies are sentinels or early indicators of this change, and can act as important messengers to raise awareness.
