Description:

Abstract:

This data set contains one table of the habitat classifications from imagery captured during aerial photographic surveys at the five primary Pacific black brant colonies on the Yukon-Kuskokwim Delta in western Alaska from 1993-2016.

Purpose:

These data were used to quantify changes in grazing lawn abundance (Carex subspathacea) over time and identify the possible factors impacting those changes.

Process_Step:

Process_Description:

Digitally overlaid 180 white sample dots (12 x 15 dot grid) on each aerial image using MATLAB Image Processing Toolbox (IPT; MathWorks Inc., Natick, MA, USA). Images were brought into Adobe Photoshop (Adobe Systems Inc., San Jose, CA, USA) and each dot was colored based on the habitat class category in which it occurred. The number of dots in each habitat class were counted using MATLAB IPT.
