James Lendemer of the New York Botanical Garden has recently made 374 lichen collections on the "limestone" barrens of the Great Northern Peninsula, at Burnt Cape, Watt's Point, and Cape Norman. Photos of a number of Lendemer's collections are available online [Note that the NYBG website can be very slow, or even unreachable, at certain times of the day.

The species of lichen that inhabit "limestone" substrates are mostly completely different from those that inhabit siliceous substrates (ie. granites or schists).
