Arctic National Wildlife Refuge shorebird nest survival plot data This file contains information pertaining to the survey plot including date and time of surveyed, survey conditions, plot location, and ecological and biological conditions of the survey plot. 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.

Note, that .ttd files viewed using Tinytag Explorer may have assessment times that are off by an hour, as the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. Also, in 2019 camera date and times were not set correctly prior to deployment. See fields... Categories: Data; Tags: ANIMALS/VERTEBRATES, Arctic, BIOLOGICAL CLASSIFICATION, BIRDS, Data, All tags...

We used the Generalized Random Tessellation Stratified (GRTS) procedure (Stevens and Olsen 2004) to obtain a spatially balanced sample of 28 plots in 2019 and 48 in 2022 within two of the four strata. In 2019, plots were equally allocated between wetland and moist strata, with 14 plots allocated to each. In 2022, additional plots were allocated to the moist stratum given the proportional availability on the landscape, with the final allocation being 30 moist plots and 18 wetland plots. We also selected an additional 20 “oversample” plots in each... Categories: Data; Tags: ANIMALS/VERTEBRATES, Application, Arctic, BIOLOGICAL CLASSIFICATION, BIRDS, All tags...

Photos are organized in folders by year. Naming convention for each photo includes nest ID and camera number. Within each NestID folder are a series of TLV files saved directly from cameras. TLV files can be saved as an AVI file to view in Windows. Note, in 2019 camera date and times were not set correctly prior to deployment. See ‘ANWR nest survival nest data’ for date and time as set on the camera at time of deployment.

Accordingly, we set out to 1) measure current nest survival rates across a large area of the Arctic National Wildlife Refuge, and 2) identify predators of nests, so as to help elucidate the potential role reproductive failure plays in current shorebird population declines. This information is also relevant for assessing the indirect effects of land management decisions such as oil and gas development on a species’ reproductive success. In 2019 and 2022, we monitored 129 shorebird nests of 9 species using...

To delineate sampling units (i.e., survey areas), we overlaid the northwest portion (i.e., northwest of the Marsh Creek Anticline) of the 1002 Area of the Arctic NWR with a grid of 16 ha plots (400 × 400 m each) in ArcGIS 10 (Environmental Systems Research Institute, Redlands, CA, USA; Alaska Albers Equal Area Conic NAD83). Given the logistical constraints for obtaining permission to access private lands within the Arctic NWR, we limited our spatial sampling to public lands administered by the U.S. Fish...
