This is the YKD egg observation data summarized into yearly stats on mean initiation and hatch dates for various species. This file is produced from the R code eggs.R.
This is the quality controlled YKD salinity data for fixed and random plots 2006 - 2019. These data are quality controlled using the R code in the file 'YKDsalinity_QC.R' to produce the data used for analysis and sharing ('YKDsalinity_QC.R'). These data should be what is used for analysis or distributed on request.
This is the YKD nest card data from 1985 to 2019 produced after processing with the R script "Nest_Cards_QC.R". This file ('Nest_Cards_1985_2019_QC.csv') should be used for producing population estimates and any other analyses. This file is what should generally be distributed for YKD nest card data requests.
This is the YKD egg observation data reformatted from the nest card data ('Nest_Cards_1985_2019_QC.csv'). The file eggs.R is used to produce this data set, and then this is further summarized into yearly stats on mean initiation and hatch dates to produce the file yearstats.csv.
This report communicates survey results to the Pacific Flyway Representative for incorporation into harvest management reports and regulatory processes. This memorandum also is shared widely with partners outside the FWS. The major products are a memo, automatically generated from an R Quarto document, and 19 comma delimited table files, one for each management index and table in the memo.

This GeoPackage contains the analysis strata ("YKG_AnalysisStrata") used in calculating population indices for geese, swans, and cranes. This layer was created from the file ("YKD_DesignStrata") when the existing rotating panel design was developed in 1999. This layer was originally created as an ArcInfo coverage, saved to a shapefile, and imported to SQLite Database format.

This is a geojson file that define the spatial polygon of the YKD nest plot study area. From 1998 to current, nest plot centroids are randomly selected from this area with the constraint that plots cannot overlap plots from the previous 5 years. This area also defined the area of inference for design-based calculations of nest population estimates. Before 1998, larger areas were sampled, so this file does not apply to those years.
