Loam
The August 2026 sample
We averaged network canopy readings from the August 17, 2026 catalog, including states and provinces with at least five published networks. Each network counts equally. This reduces the influence of a single unusual location, but it is still a sample of Loam coverage, not a survey of all trails in each state.
A canopy value is an environmental input sampled around a network's mapped location. It does not measure tree cover continuously over every trail mile. Loam uses US and Canadian canopy providers described on the sources page. The frozen catalog does not identify the upstream raster release or sampler revision for every row, so those current provider notes should not be read as complete historical provenance.

Look beyond the state average
Two places with similar averages can contain very different rides. Check the contributing networks and their range before using a state average to plan a trip.
Average canopy can hide a wide spread. British Columbia averaged 87.4%, but its 16 network readings ran from 10% to 100%. Ontario covered the full 0% to 100% range. North Carolina was much tighter, from 91% to 98% across seven networks.
The downloads identify every contributing network and preserve the catalog used for the August 17 publication. The JSON includes the source revision and field definitions. Check an individual network for current conditions before riding.
About Loam estimates
Loam estimates conditions from weather, soil, and terrain. It does not measure the trail surface directly or override an official closure. Read how the estimate works and see the published checks and their limits.
