The project is on the San Joaquin River, offshore from 801 Minaker Drive, City of Antioch. We understand that the project consists of doing some upgrades to the Antioch Wharf on the San Joaquin River. The upgrades consist of removal of some timber breasting and mooring dolphins and wooden walkways, install four steel monopiles below the mudline, and repair one timber piling and twelve stringers on the wharf. At this time we do not have any comments to submit, since this is a project in the City of Antioch, in an unformed drainage area, and the project would not have a significant impact to the drainage area. We appreciate the opportunity to comment on this project in regards to drainage matters. If you should have any further questions, you may contact me at (925) 313-2308 or by e-mail at [email protected].

  • Peer Review Plan for Draft Recovery Criteria for the Lange’S Metalmark Butterfly (Apodemia Mormo Langei), Oenothera Deltoides Subsp
    Peer Review Plan for Draft Recovery Criteria for the Lange’s metalmark butterfly (Apodemia mormo langei), Oenothera deltoides subsp. howellii (Antioch Dunes evening- primrose), and Erysimum capitatum var. angustatum (Contra Costa wallflower) About the Document Title: Draft Amendment Adding Recovery Criteria to the Recovery Plan for Three Endangered Species Endemic to Antioch Dunes, California: Lange’s metalmark butterfly (Apodemia mormo langei), Oenothera deltoides subsp. howellii (Antioch Dunes evening-primrose), and Erysimum capitatum var. angustatum (Contra Costa wallflower) Description of the Document: This document proposes draft recovery criteria for Lange’s metalmark butterfly (Apodemia mormo langei; Lange’s metalmark), Oenothera deltoides subsp. howellii (Antioch Dunes evening-primrose), and Erysimum capitatum var. angustatum (Contra Costa wallflower) that will be made available to the public for review and comment. The intent of the draft recovery criteria is to establish objective, measurable criteria which, when met, would result in determinations for downlisting and delisting of Lange’s metalmark, O.d. subsp. howellii, and E.c. var. angustatum. About the Peer Review Process Type of Review: Individual letters The U.S. Fish and Wildlife Service (Service) will provide each peer reviewer with information explaining their role and instructions for fulfilling that role, the draft recovery criteria, and a list of citations as necessary. The purpose of seeking independent peer review is to ensure use of the best scientific and commercial information available and to ensure and to maximize the quality, objectivity, utility, and integrity of the information upon which the report is based, as well as to ensure that reviews by recognized experts are incorporated into the recovery planning process.

First observations of Mormon Metalmark (Apodemia mormo ) oviposition behaviour in Canada. Canadian Field-Naturalist 126(1): 3 4–37. We present new information on oviposition behaviour in the Mormon Metalmark, Apodemia mormo Felder and Felder, 1859 , documented in Grasslands National Park of Canada, Saskatchewan, in August 2011. The Mormon Metalmark is found through - out the U.S. southwest; little is known about its life history in the northern populations found in Canada. We provide photo - graphic documentation of the butterfly laying single eggs directly on soil or rocks. These observations differ from those recorded in the southern part of its range, where it lays eggs in groups of 2–4 on various locations of the host plant, Branched Umbrella- Plant, Eriogonum pauciflorum Pursh. This is the first published account of oviposition behaviour of this species in Canada in the most northern part of its range. Key Words: Mormon Metalmark, Apodemia mormo, Grasslands National Park of Canada, Saskatchewan, Lepidoptera, ovipo - sition, eggs. The Mormon Metalmark, Apodemia mormo Felder Recent work on the population genetics of the Mor - and Felder, 1859, is a butterfly of the primarily neo - mon Metalmark in the northern part of its range has tropical family Riodinidae.

  • Poisonous Native Range Plants Anthony Knight Bvsc., MS
    Poisonous native range plants Anthony Knight BVSc., MS. DACVIM College of Veterinary Medicine & Biomedical Sciences Colorado State University, Fort Collins, Colorado [email protected] Plant poisoning is a common problem throughout North America, causing significant economic losses not only through death loss, but through the costs associated with reproductive loss, poor growth rates, herbicides, etc. Through good pasture management, recognizing toxic plants, and by understanding the effects of toxins on animals, plant poisoning can be largely avoided. Plants contain a variety of toxic compounds that help to deter herbivores and insects from eating them. A classic example of this is milkweed (Asclepias species) that contains a milky sap that is an irritant and therefore distasteful, and is also poisonous. Other compounds found in plants that may be toxic to animals are normal components of plants essential for plant growth. Nitrates and cyanogenic glycosides, for example, are found in a wide variety of plants and are essential in the formation of plant protein. Yet another reason some plants such as locoweed (Astragalus and Oxytropis species) are poisonous is that they have developed a mutually beneficial relationship with specific fungi (endophytes) that, when growing in the plant, produce a toxic alkaloid poisonous to horses and livestock. There are numerous native range plants that are potentially poisonous to livestock, but rarely is an animal poisoned by eating a few mouthfuls of these plants. This famous quote by Paracelsus summarizes it best. "All things are poison and nothing is without poison; only the dose makes that a thing is no poison." In other words, “the dose makes the poison” Paracelsus (1493-1541).

    MONARCH NECTAR PLANTS Southwest Left to right: Lyreleaf greeneyes, monarch on blue mistflower, and spider milkweed. The Southwest is a land of geological wonders and climatic degradation from other causes, natural disease and predation, extremes. Covering the bulk of Arizona and New Mexico, as climate change, and widespread insecticide use. Because of well as sections of California, Nevada, Utah, Colorado, and the monarch’s migratory life cycle, it is important to protect Texas, the southwest region boasts surprisingly lush riparian and restore habitat across their entire range. Adult monarchs zones, high deserts, extensive sand dunes, wild cactus gardens, depend on diverse nectar sources for food during all stages of and isolated mountain ranges. Precipitation is minimal the year, from spring and summer breeding to fall migration except during the summer monsoon season, when violent and overwintering. Inadequate milkweed or nectar plant food rainstorms can strike the region. The incredible diversity of sources at any point may impact the number of monarchs that landscapes and plant communities has contributed to highly successfully arrive at overwintering sites in the fall. diverse pollinator assemblages, from the hummingbird-sized Providing milkweeds and other nectar-rich flowers sphinx moth to the brightly colored milkweed butterflies—the that bloom where and when monarchs need them is the most monarchs, queens, and soldiers. significant action you can take to support monarch butterfly Each spring, monarchs leave hundreds of overwintering populations.

  • Pollinator Plant Recommendations for New Mexico
    TECHNICAL NOTES U.S. DEPARTMENT OF AGRICULTURE NATURAL RESOURCES CONSERVATION SERVICE ALBUQUERQUE, NEW MEXICO Revised March, 2015 PLANT MATERIALS TECHNICAL NOTE NO. 71 (Final Revision) Pollinator Plant Recommendations for New Mexico David R. Dreesen, Agronomist/Horticulturist Los Lunas Plant Materials Center Tessa R. Grasswitz, Assistant Professor, Urban/Small Farms IPM Specialist New Mexico State University In recent years, the phenomenon known as Colony Collapse Disorder and the resultant declines in domesticated honey bee populations (both in the U.S. and elsewhere) have prompted increasing concern over the long-term sustainability of crop pollination services. In many cases, however, it has been shown that native (wild) bee species can provide pollination services equal, or superior to, those of hive bees (Garibaldi et al., 2013), provided that their habitat requirements (such as nesting sites and alternative forage sources) are met. Consequently, there has been considerable interest in creating habitat that will help conserve both native wild bees and domesticated honeybees. Until recently, however, there have been no state-specific guidelines for those wishing to install pollinator plantings appropriate to New Mexico conditions. To address this need, staff from the Los Lunas Plant Materials Center and the NMSU Agricultural Science Center at Los Lunas conducted field trials from 2010-2015 to develop the current recommendations for plants that will sustain bees (and other beneficial insects) throughout the growing season. During the project, a total of 380 plant species were tested, including 260 herbaceous perennials (215 native and 45 introduced), 85 annuals and biennials (60 natives and 25 introduced), and 35 native shrubs. Additional details of the pollinator project, including the trial sites, are given in Dreesen and Grasswitz (2013).
