2015_Analysis_Compare2010&2015.xlsx is an Excel file created by MBM-AK to test statistical differences between the 2010 and 2015 Alaska Trumpeter Swan Survey results.

These .csv tables, YYYY_Survey_Area.csv (where YYYY = survey year), list the U.S. Geological Survey 1:63,360 scale quadrangle maps that comprised the survey areas of the 1968-2015 Alaska Trumpeter Swan Surveys. Each year’s survey area consisted of a set of the 1:63,360 scale maps, where each map represented a potential sampling unit. The 1968-2005 surveys were designed to census the entire survey area, and thus all of the maps were surveyed in these years. The 2010 and 2015 surveys were stratified random samples (optimally allocated to minimize cost for a fixed variance); therefore, only a selected set of 100 maps were surveyed in these years. (Note: additional .csv tables are available in the survey’s project archive...

This is the collection of raw data was collected during MBM-AK TLSA annual molting goose surveys. Partial quality control has been completed for these data: following each survey, the observer listened to their survey recording that documented counts along transects and then transcribed these findings into these raw datasets (‘raw_data’). The observer listened to their recording a second time in order to confirm that their transcriptions were correct. Further quality control and tidying was completed for these raw data using R scripts noted by the file extension ‘.Rmd’ located in the ‘GitHub_Annual_Report_Code’ folder. Ultimately, these scripts produced final datasets (‘final_data’) containing data used in annual...

These are the observer names, observer initials, year, and unique observer number for all observe that collected data on the YKD nest plot project from 1985 to 2019. This data is used with the nest card data to in various ways, but primarily to calculate cumulative observer experience for nest detection rates. This file is also used for quality control and reconciling non-unique observer initials across years.

From 1995 to 1999, a subset of nest plots were searched twice by field crews to estimate nest detection probability by mark-recapture methods. Over the five years, 30 plots were searched twice and over 2700 unique nests were found. From these data, nest detection probability is estimated using a Huggins-type mark recapture model where individual-level covariate effects of nest and observer attributes were estimated. These estimates are then used to predict nest detection rates in other years based on covariates of nests and observers. Nest detection rates are then applied to annual plot search to estimate nest populations for each species in the sampled area.

This dataset includes a polygon vector shapefile illustrating the location of rapid and intensive survey plots surveyed on the Yukon Delta as part of the Program for Regional and International Shorebird Monitoring (PRISM). This dataset provides the geographical location of survey plots that can be linked to the data collected in the field via the PlotID field.A portion of these data are available on ServCat (https://ecos.fws.gov/ServCat/Reference/Profile/57583).Much of these data have been published in Lyons, J.E., S.C.

This file provides information on shorebirds observed during 10-minutes point counts including date and time, location, weather information, and shorebird observations.These data do not represent all locations where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including differences in species, habitat, time-of-year, weather conditions, survey effort, and individual surveyor. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended...

The primary objective of this project was to monitor the growth of shorebird chicks by recapturing them from hatch to fledgling in relation to food abundance and weather conditions. In 2014 and 2015, we attempted to estimate the impacts of trophic mismatch by experimentally creating late hatched broods by refrigerating eggs to delay hatch. Transmitters were then attached to adults and chicks to follow and recapture chick in order to estimate growth rates and survival (see annual protocol documents for further information).Information for the Utqiagvik chick monitoring study were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these...

R code that takes in the nest capture history data (chdata.csv), reformats it for model fitting in Program Mark via the R package RMark. A series of models of increasing complexity are fit and compared using AIC. Output is written to text files for each model but is generally not used or saved. Code can be run to generate model results and R workspaces/ object to inspect parameter estimates. The primary purpose of this code is to explore model structures for predicting detection and as an attempt to reproduce historically used parameter estimates in past nest plot reports (e.g., Fischer et al. 2017 and earlier). Results from ‘Model 7’ are most similar to detection estimates used in the past.

This layer represents agricultural resource priorities in the Highlands region. 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 ranges from 0 to 8, with 8 being highest priorities for agricultural preservation in the Highlands Region. The layer scores all 30m cells that are, or were, in agricultural use in 2016 or 2021 based on the 2021 NLCD layer (classes 81 and 82). Cells with prime, state, and local/unique...
