Description: Chinquapin oak - nodding onion alvar woodland is found only in western Lake Erie on Pelee Island in southern Ontario, Canada, on shallow soils over flat limestone outcrops (pavements). This is a savanna community with scattered trees forming 10-25% canopy cover, and a variable understory with shrubby patches and grassy patches. <i>Quercus muehlenbergii</i> is the most abundant tree, but <i>Quercus bicolor, Fraxinus quadrangulata</i>, and <i>Juniperus virginiana</i> are also characteristic trees. The most abundant shrubs in the shrubby patches are <i>Cornus drummondii, Viburnum rafinesquianum, Rhus aromatica, Zanthoxylum americanum, Rhus typhina</i>, and <i>Symphoricarpos albus</i>. The dominant grass in the grassy patches is <i>Poa compressa</i>; other characteristic herbs include <i>Allium cernuum, Carex molesta, Packera paupercula (= Senecio pauperculus), Panicum flexile</i>, and <i>Isanthus brachiatus (= Trichostema brachiatum)</i>. Most of the area within this community has been grazed, and several weedy exotic species are common, including <i>Poa pratensis</i> and <i>Hypericum perforatum</i>.
