The Moccasin Bluff site (also designated 20BE8) is an archaeological site located along the Red Bud Trail and the St. Joseph River north of Buchanan, Michigan.It was listed on the National Register of Historic Places in 1977, [1] and has been classified as a multi-component prehistoric site with the major component dating to the Late Woodland/Upper Mississippian period.
Very rare species are not considered axiophytes; for a species to be a useful indicator of quality habitat it must be relatively frequent in those habitats, but scarce elsewhere. A typical example would be dog's mercury (Mercurialis perennis), a plant slow to colonise new sites, but common in ancient woodland and old hedgerows.
Providing that the area has remained as woodland, the stand is still considered ancient. Since it may have been cut over many times in the past, ancient woodland does not necessarily contain trees that are particularly old. [1] For many animal and plant species, ancient woodland sites provide the sole habitat.

Pre-existing natural communities remained largely intact south of the glaciers, but saw an increase in dominance of pine and a now-extinct species of temperate spruce, (Picea critchfieldii). This area included many plant communities that rely on a lightning-based fire regime, such as the longleaf pine woodland. When the glaciers began to ...
Presence of the wild service tree is commonly taken as an indicator of ancient woodland. 71 different species of bird have been recorded, alongside foxes, grey squirrels, bat species including pipistrelle, Natterer's bat, common noctule and the rare Leisler's bat, 180 species of moth, 12 species of butterfly and 80 species of spider.
Ancient trees exist in many forms and sizes, with ages ranging according to species and environment, with some lasting for hundreds of years; smaller trees, such as in orchards, can exhibit veteran characteristics after only a few decades. A girth of more than 3 meters at 1.5 meters could be used as a measure to identify if a tree is a veteran.
A bluebell wood is a woodland that in springtime has a carpet of flowering bluebells (Hyacinthoides non-scripta) underneath a newly forming leaf canopy. The thicker the summer canopy, the more the competitive ground-cover is suppressed, encouraging a dense carpet of bluebells, whose leaves mature and die down by early summer.
