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.
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.
The plant is an ancient woodland indicator, as the ants rarely carry the seeds more than a few yards, seldom crossing a field to go to a new woodland. The Latin specific epithet pratense means "of meadows". [2] Melampyrum pratense is a food plant of the caterpillars of the heath fritillary (Melitaea athalia), a butterfly. [3]
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.

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.
Some epiphytic lichen species may be used as "ancient woodland indicators"; they can used to quantitatively assess the degree to which a forest has had a long history of canopy continuity. [11] The presence of these species is a reliable indicator that the forest has existed back to early medieval times, without being clear-cut and regrown.
