Highest tree canopy by state

Average tree canopy cover.

This measure has no better end. The order describes the states, it does not rank them — see the other direction.

Average percent tree-canopy cover across the county's mapped land pixels. The USDA Forest Service NLCD product masks water and non-tree agriculture, then smooths the annual satellite series; it describes broad tree cover, not street-tree access, park acreage, shade on a particular block, or forest ownership. County values are means of the published 30-m pixels inside Census county boundaries, and state values are population-weighted county means. Current source: 2025 in the contiguous U.S.; 2023 in Hawaii, where the next release has not yet been published.

Not ranked, because this measure is not published for them: Alaska. The current complete product covers the contiguous U.S. and Hawaii. Alaska's available layer covers only the southeast, so Alaska is intentionally left blank rather than shown as a misleading statewide figure.
