Canada Goose Survey 2019

I was hired by the City of Powell River to monitor Canada Goose (Branta canadensis) populations in the summer of 2019. 

My intention here is to provide some additional maps, photographs and data that were, for reasons of space, impossible to include in my final report.

Simple abundance by count (Excel format)

Canada Goose survey, 2019. Data are simple abundance of juveniles and adults with a “cumulative detections curve” for all birds. Click to enlarge

I’ve also included survey point locations (a “zipped” kml for viewing in Google Earth) and shapefiles that contain simple abundance, and log(x+1) transfomed abundance values.

Sites with “zero-counts” are excluded. Data are normalized (log x+1) values.
