Many North American shorebird species are experiencing significant population declines, but we have incomplete information about the population sizes and trends for most species. Conservation efforts are underway throughout the Hemisphere to reverse these declines, but we cannot measure the success of those efforts until we have an accurate assessment of population sizes and trends. The Program for Regional and International Shorebird Monitoring (PRISM) is a broad-scale, multi-national effort to monitor both the sizes and trends of shorebird populations (https://www.shorebirdplan.org/science/program-for-regional-and-international-shorebird-monitoring/). PRISM also strives to describe the distribution and habitat...

This file provides final processed GPS location data for Whimbrel tagged from 2019-2022 collected via the ARGOS website. Raw data files were processed with Lotek Argos-GPS Data Processor V3.18 (2018-2021) or V4.2 (2022).The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions, or intended use. The originators of this dataset shall not be held liable for improper or incorrect use of the data described and/or contained herein.Potential users of these data should first contact the data authors...

Boreal wetland birds are among the continent’s most rapidly declining avifauna. However, many of these declining species still breed commonly on military lands in Alaska. We propose to survey these species, as well as, additional boreal wetland obligates at breeding sites on Eielson Air Force Base (AFB) and then track migratory movements throughout the annual cycle. Our surveys aim to identify important wetland features for conservation and levels of fragmentation that may reduce bird breeding numbers. Our tracking of birds during migration will identify habitats for conservation at key stopover and wintering areas, and therefore allow conservation on military lands in Alaska to be directly linked to conservation...

The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...
The Delaware River clubtail (Gomphurus septima delawarensis) is an endemic dragonfly subspecies found in the Delaware River watershed. Due to significant data gaps regarding its taxonomy, distribution, habitat associations, and response to key threats, it is considered a Science Needs species by the Science Applications program in the Northeast. This pilot study is focused on the known historic locations for the subspecies in New York and intends to field-test survey methodologies for assessing its distribution within the Delaware watershed. We will collect all Gomphidae exuviae (shed larval skins) encountered during timed searches at 11 historical locations across New York. These surveys will be repeated at these...

This contain a zip folder of comma delimited (CSV) files for each of the 19 tables in the report. It is produced automatically upon compiling the R Quarto code. Column headers are difference than in the tables in the report but order is exactly the same. Refer to the report to understand meaning of the columns. Each cell of the tables contain a management index estimate or the standard error of the estimate.

Dusky Canada geese (Branta canadensis occidentalis) comprise one of the smallest populations of geese in North America and their breeding range is limited to Prince William Sound, primarily the Copper River Delta, and Middleton Island, Alaska. The Alaska Region of Migratory Bird Management initiated an aerial breeding pair survey on the Copper River Delta in 1986 after reported declines in the abundance of dusky Canada geese on their nesting and wintering grounds. Since 2008, the Pacific Flyway Council uses results of the aerial breeding pair survey, together with Middleton Island ground counts conducted by the Alaska Department of Fish and Game, as a management index to determine optimal hunting regulations. Survey...

The standard operating procedures (SOP) document for the overall WBPHS, including the Alaska strata, was updated by USFWS Division of Migratory Bird Management Branch of Migratory Bird Surveys on 21 April 2022. This SOP applies to all survey crews, including Alaska’s.

This collection comprises the log files that accompany the quality-controlled (QC) WBPHS-AK transcribed bird-observation data files. The log files were produced when the original (“raw”) transcribed data were run through the QC process via the “Greenlight” script within the R package “AKaerial” (available at github.com/USFWS/AKaerial). The log files describe any changes that were made to the raw transcribed data during the QC process. There is one log file for each QC transcribed data file: WBPHS_YYYY_QCLog_OOO.html, where YYYY=Year and OOO=Observer initials.

This is a csv file that records the full name and initials used in the nest data to identify observers. This file is used during quality control to produce the final data set.

This is a zip folder of printed emails (pdf) and Word (.docx) files that describe data issues used to during the quality control process. See the file wrangle_2022.R and comments within for actually quality control process.

This is the field protocol used to instruct crews on data collection while in the field at found nests or dead birds during the 2022 distance sampling season. Used in conjunction with the document Field_Protocol_Distance_Sampling_20220506.pdf, which describes the distance sampling protocol, and the document YDNC_2022_map_20220419.pdf, which describes crew areas within the survey area.

This is an html report produced from the Rmarkdown code found in the file YKD-sample-frame.Rmd. It presents the design of the, some background and some additional analysis based on the history of the plot survey.
This layers represents Underresourced Communities in the Highlands region that have been identified by the states and supplemented with a National dataset. This layer is intended to inform grant proposals for the Highlands Conservation Act. The Highlands Conservation Act authorizes the Secretary of the Interior to provide financial assistance to the States of Connecticut, New Jersey, New York, and Pennsylvania (Highland States) to preserve and protect high priority conservation land in the Highlands region.This layer was created by merging underresourced communities identified in 5 state layers and 1 national layer. The state layers include NY Disadvantaged Communities (NY DAC), CT Environmental Justice Block Groups...
