From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, and New River. Our objectives for the Oregon coastal population in 2007 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue selected use of mini-exclosures (MEs) to protect nests from predators and evaluate whether exclosure use can be reduced, 4) determine nest success, 5) determine fledgling success, 6) monitor brood movements, 7) collect general observational data about predators, and 8) evaluate the effectiveness of predator management. We observed an estimated 181-184 adult Snowy Plovers; a minimum of 162 individuals was known to have nested. The adult plover population was the highest estimate recorded since monitoring began in 1990, and we found the highest number of nests since monitoring began in 1990 (n = 202). Overall Mayfield nest success was 33%. Exclosed nests (n=38) had a 66% success rate, and unexclosed nests (n=164) had a 41% success rate. Nest failures were attributed to unknown depredation (20%), one-egg nests (20%), corvid depredation (17%), abandonment (16%), unknown cause (7%), unknown mammal depredation (7%), overwashed (3%), infertility (3%), coyote depredation (3%), wind/weather (3%), raccoon depredation (1%), and adult plover depredation (1%). We monitored 89 broods, including four from unknown nests, and documented a minimum of 123 fledglings; the highest number of fledglings since monitoring began in 1990. Overall brood success was 82%, fledgling success was 54%, and 1.60 fledglings per male were produced. Continued predator management, habitat improvement and maintenance, and management of recreational activities at all sites are recommended to achieve recovery goals.

  Citation × Citation Citation Abstract Copy Title: An Ecological Approach to Integrating Conservation and Highway Planning Volume 2 Author: CH2M HILL, NatureServe, Institute for Natural Resources, Transposition Research Board of the National Academies, Parametrix, Inc. This report is intended to help transportation and environmental professionals apply ecological principles early in the planning and programming process of highway capacity improvements to inform later environmental reviews and permitting. Ecological principles consider cumulative landscape, water resources, and habitat impacts of planned infrastructure actions, as well as the localized impacts. The report introduces the Integrated Ecological Framework (Framework or IEF), a nine-step process for use in early stages of highway planning when there are greater opportunities for avoiding or minimizing potential environmental impacts and for planning future mitigation strategies. Success requires some level of agreement among stakeholders about prioritization of resources for preservation or restoration. This implies long range environmental planning as a companion to long range transportation planning so that there is a basis and methodology for prioritization. This report provides a structured collaborative way to approach these issues. It does not address environmental mitigation and permitting actions required by current law or regulation. The report provides technical background on cumulative effects assessment, ecological accounting strategies, ecosystems services, and partnership strategies, along with a summary of the available ecological tools that are most applicable to this type of work. The appendices document three pilot projects that tested the approach during the research. The Framework details steps to enhance ecological considerations and efficiency in the early stages of planning highway capacity projects. Transportation professionals must routinely interact with numerous agencies in the course of planning highway expansions. These materials are intended to help each stakeholder better understand the missions and responsibilities of the other stakeholders and provide a structured and repeatable framework for interaction, thus allowing for agreement on ecological priorities. Use of the Framework can streamline the delivery of highway projects and improve water resources and habitats. The research from SHRP 2’s Capacity Project C06 produced two volumes of reports and a companion guide. Volume 1 (forthcoming) covers institutional issues and provides examples of techniques such as banking and programmatic agreements that can be used in the highway planning process. The guide (forthcoming) provides step-by-step information to help practitioners use the Framework. Essential content from the C06 project is available on the Transportation for Communities: Advancing Projects through Partnerships website (www.transportationforcommunities.com).

Two products developed by ODF staff were the focus of this science review: The Influence of Modeled Management Scenarios on Habitat for Species of Concern (ODF, 2009a; hereafter referred to as “SOC analysis”) and the Board of Forestry State Forests Performance Measures: An Evaluation of the Achievement (ODF, 2009b). The purpose of the review and this Science Advisory Team report is to: (1) characterize the environmental, economic, and social analyses that were conducted by ODF in 2009 and discuss whether ODF analyses were consistent with best available science in each field; (2) identify and discuss gaps; (3) discuss the range of uncertainty of expected outcomes as detailed in the ODF reports; (4) present other ways to conduct analysis or think about the questions, if applicable; and (5) recommend, if necessary, performance measures for measuring environmental, economic, and social outcomes.

From 6 April – 19 September 2011 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius nivosus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, New River, and Floras Lake. Our objectives for the Oregon coastal population in 2011 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue use of mini-exclosures(MEs) to protect nests from predators when and where needed, 4) determine nest success, 5) determine fledging success, 6) monitor brood movements, 7) collect general observational data about predators, and 8) evaluate the effectiveness of predator management. We observed an estimated 247-253 adult Snowy Plovers; a minimum of 214 individuals were known to have nested. The adult plover population was the highest estimate recorded since monitoring began in 1990. We monitored 289 nests in 2011, the highest number of nests since monitoring began in 1990. Overall apparent nest success was 50%. Exclosed nests (n = 48) had a 71% apparent nest success rate, and unexclosed nests (n = 241) had a 48% apparent nest success rate. Nest failures were attributed to unknown depredation (22%), corvid depredation (20%), unknown cause (18%), one-egg nests (16%), abandonment (15%), wind/weather (3%), mammalian depredation (2%), adult plover depredation (2%), infertility (1%), and rodent depredation (1%). We monitored 148 broods, including four from unknown nests, and documented a minimum of 168 fledglings. Overall brood success was 71%, fledging success was 46%, and 1.57 fledglings per male were produced. Continued predator management, habitat improvement and maintenance, and management of recreational activities at all sites are recommended to achieve recovery goals.
