This forecast is built from the species that stand here, their elevation and this September’s weather, and corrected in season by cameras, foresters and our own crew. Out here we score it against NASA's satellite record of when the canopy shuts down, read inside each unit’s own boundary: two dates in three land within 12 days of it. How this map is made
