Bee Colony Health Trends 2009-2012: Active, Inactive, and Nest Data #1908471 (License: Personal Use)

The chart displays stacked bar graphs for colony counts per year (2009-2012), segmented into active (blue), inactive (red), and unknown (green) statuses, with total colony numbers labeled atop each bar. A secondary purple line plots the number of active nests on the right y-axis, peaking at 1,073 in 2009, dipping to 829 in 2011, then rising to 906 in 2012. This dual-axis visualization highlights both colony composition shifts and nesting activity trends over time.

Used in entomology reports, agricultural extension resources, or environmental policy briefs to illustrate pollinator population dynamics; matches user intent seeking longitudinal data on hive health or colony collapse patterns.
