I would define a local area has any place that is within an hour’s drive or so. A reasonable day trip.
Speaking from an Ontario perspective have you …
Visited all the official trail system (that are listed in a local trail adjacency)?
Visited all the provincial parks operating and non-operating, conservation reserves, conservation areas, crown land, private camp ground with trails, city parks with natural features?
Attempted to find as many different habitats to visit such as deciduous, coniferous forest, swamps, marshes, fens, bogs, lakes, rivers, riffles, open areas, grasslands etc?
In addition to hiking have tried snowshoeing, mountain biking, canoeing, boating, wading to get into more remote areas?
Looked at geology maps for less common features such as eskers, kames, ice-contact deltas, etc?
Looked at soil maps looking for pockets of acid or basic soil, alluvial areas, etc?
Have you tried different observing equipment, ie close-focusing binoculars, cameras, insects nets, etc to look at unseen local wildlife?
I sure haven’t explored all my local area yet, although I have blessed with still having some left (I live in North Bay, Ontario) because I don’t live in an area that is mostly agriculture or city scape. I am currently going through unmarked roads up Highway 11 North. Yesterday I did kilometer 30 from home. The road turned out to be a trapper line trail with a wetland plus a natural gas and hydro corridor near the end. A less interesting location but interesting enough for a single visit.
