Two maps and one switch. Fly fishing — coldwater streams in Michigan, Virginia and North Carolina. Upland birds — Michigan birds: ruffed grouse, woodcock, pheasant, turkey and bobwhite. Use Fish / Bird at the top of this panel to change which one you are looking at.
The water comes from the Schrems WMTU Kent County inventory and the state classifications published by MDNR, VDWR and NCWRC. The survey readings were mostly taken in 2011, and a classification is a standing one — a stream that ran cold then may not run cold today.
The birds are occurrence records, from GBIF, binned by watershed and scored against how hard anyone looked there — not a habitat model, and not a count of birds. A dark cell means people have reported that species; an empty one often means nobody looked.
Access points and public land are leads, not permission. Neither the access pins nor the huntable-land boundaries have been checked against parcel records, and public land nearby doesn't make the bank public. Where you may legally stand, fish or carry a gun differs by state and by parcel — check before you go.
Pins sit where a road crosses the water, not where a surveyor stood. Only records that could be placed are on the map — the rest are listed in the manual so you know they exist.
