A Guide to Conservation Plantings on Critical Areas for the Northeast Critical Areas for the Northeast A guide to A guide to Conservation Plantings A guide to Conservation Plantings on Critical Areas for the Northeast on Critical Areas for the Northeast A guide to Conservation Plantings on Critical Areas for the Northeast This guide covers some factors to consider when planning and implementing critical area seedings and conservation plantings. It discusses the differences between critical area stabilization, conservation plantings and restoration with an emphasis on critical area stabilization. The use of native species, diversity and the concern for the spread of invasive species is emphasized. It points out the importance of soils and building and maintaining soil quality as and integral part of all conservation plantings. It addresses the need for other measures to control erosion where needed to withstand high velocities of water and to divert water to facilitate successful seedings. It stresses mulching as an integral part of most critical area seedings and plantings. The guide is divided into sections based on the steps in conducting conservation plantings starting with planning, selecting plant material, purchasing plant materials to installing the seeding or planting, and not by plant type. nrcs.usda.gov A GUIDE TO Conservation Plantings on Critical Areas for the Northeast Paul R.

  • Threatened Species Status Assessment Manual
    THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 THREATENED SPECIES STATUS ASSESSMENT MANUAL A guide to undertaking status assessments, including the preparation and submission of a status report for threatened species. Knowledge of species and their status improves continuously. Due to the large numbers of both listed and non-listed species, government resources are not generally available to carry out regular and comprehensive assessments of all listed species that are threatened or assess all non-listed species to determine their listing status. A status assessment by a group of experts, with their extensive collection of knowledge of a particular taxon or group of species could help to ensure that advice is the most current and accurate available, and provide for collective expert discussion and decisions regarding any uncertainties. The development of a status report by such groups will therefore assist in maintaining the accuracy of the list of threatened species under the EPBC Act and ensure that protection through listing is afforded to the correct species. 1. What is a status assessment? A status assessment is a assessment of the conservation status of a specific group of taxa (e.g. birds, frogs, snakes) or multiple species in a region (e.g. Sydney Basin heathland flora) that occur within Australia. For each species or subspecies (referred to as a species in this paper) assessed in a status assessment the aim is to: provide an evidence-based assessment

F.1.1 Birds of Arctic Refuge A total of 201 bird species have been recorded on Arctic Refuge. This list describes their status and abundance. Many birds migrate outside of the Refuge in the winter, so unless otherwise noted, the information is for spring, summer, or fall. Bird names and taxonomic classification follow American Ornithologists' Union (1998). F.1.1.1 Definitions of classifications used Regions of the Refuge . Coastal Plain – The area between the coast and the Brooks Range. This area is sometimes split into coastal areas (lagoons, barrier islands, and Beaufort Sea) and inland areas (uplands near the foothills of the Brooks Range). Brooks Range – The mountains, valleys, and foothills north and south of the Continental Divide. South Side – The foothills, taiga, and boreal forest south of the Brooks Range. Status . Permanent Resident – Present throughout the year and breeds in the area. Summer Resident – Only present from May to September. Migrant – Travels through on the way to wintering or breeding areas. Breeder – Documented as a breeding species. Visitor – Present as a non-breeding species. * – Not documented. Abundance . Abundant – Very numerous in suitable habitats. Common – Very likely to be seen or heard in suitable habitats. Fairly Common – Numerous but not always present in suitable habitats. Uncommon – Occurs regularly but not always observed because of lower abundance or secretive behaviors.

  • Conservation–Protection of Forests for Wildlife in the Mississippi Alluvial Valley

Twedt 3,* 1 Lower Mississippi Valley Joint Venture, 193 Business Park Drive, Ridgeland, MS 39157, USA; [email protected] (A.B.E.); [email protected] (A.E.M.) 2 Lower Mississippi Valley Joint Venture, 11942 FM 848, Tyler, TX 75707, USA; [email protected] 3 U.S. Geological Survey, Patuxent Wildlife Research Center, 3918 Central Ave., Memphis, TN 38152, USA * Correspondence: [email protected]; Tel.: +1-601-218-1196 Received: 2 December 2019; Accepted: 23 December 2019; Published: 8 January 2020 Abstract: The nearly ubiquitous bottomland hardwood forests that historically dominated the Mississippi Alluvial Valley have been greatly reduced in area. In addition, changes in hydrology and forest management have altered the structure and composition of the remaining forests. To ameliorate the detrimental impact of these changes on silvicolous wildlife, conservation plans have emphasized restoration and reforestation to increase the area of interior (core) forest habitat, while presuming negligible loss of extant forest in this ecoregion. We assessed the conservation–protection status of land within the Mississippi Alluvial Valley because without protection, existing forests are subject to conversion to other uses. We found that only 10% of total land area was currently protected, although 28% of extant forest was in the current conservation estate. For forest patches, we prioritized their need for additional conservation–protection based on benefits to forest bird conservation afforded by forest patch area, geographic location, and hydrologic condition. Based on these criteria, we found that 4712 forest patches warranted conservation–protection, but only 109 of these forest patches met our desired conservation threshold of >2000 ha of core forest that was >250 m from an edge.
