Photograph-based seed cone counts of white spruce (Picea glauca) trees from treeline field sites across the Brooks Range, Alaska 2019-2022

Photograph-derived counts of seed cones on white spruce (Picea glauca) trees at elevational (alpine) & lower (arctic) treelines at 19 research sites along a west-east gradient in Alaska's Brooks Range. Photographs are from a single angle and thus represent a "cone production index"...
