Cottonwood Dune<br />
CEGL005119<br />
DESCRIPTION: The canopy is typically open (25-80% cover) and may even be scrubby due to wind damage. The<br />
most common dominant is Populus deltoides, <strong>of</strong>ten in association with Juniperus virginiana. Quercus spp. (including<br />
Quercus macrocarpa, Quercus rubra, and Quercus velutina) may occur, particularly when <strong>the</strong>re are adjacent oak<br />
forests. Shrub and vine species include Cornus drummondii, Par<strong>the</strong>nocissus quinquefolia, Rhus typhina, Salix<br />
amygdaloides, Salix exigua, Salix fragilis, and Vitis riparia. Morella pensylvanica (= Myrica pensylvanica) is common<br />
at Presque Isle in Pennsylvania. Herbaceous species are scattered, but include Asclepias syriaca, Elymus virginicus,<br />
Rumex acetosella, Schizachyrium scoparium, and Strophostyles helvula (Anderson 1996, Fike 1999).<br />
This community occurs in dune fields and on <strong>the</strong> most stable dune ridges.<br />
COMMENTS: 2, MCS. Juniperus virginiana may form enough <strong>of</strong> a dominant without Populus deltoides that it may<br />
deserve its own type (Lee et al. 1998).<br />
CONSERVATION RANK: G1G2. There are probably fewer than 60 occurrences rangewide. Occurrences tend to be<br />
small, averaging less than 20 acres, so <strong>the</strong>re is probably less than 1000 acres rangewide. This community is<br />
restricted to shores <strong>of</strong> <strong>the</strong> eastern Great Lakes and Lake Champlain. There has been a significant decline in<br />
occurrences due to residential development along <strong>the</strong> shores <strong>of</strong> <strong>the</strong> eastern Great Lakes and Lake Champlain. The<br />
community requires stabilized sand dunes along <strong>the</strong>se large lakes.<br />
DISTRIBUTION: This community occurs in dune fields and on <strong>the</strong> most stable dune ridges in <strong>the</strong> sou<strong>the</strong>rn Great<br />
Lakes region, especially around Lake Erie and Lake Ontario, ranging from <strong>Ohio</strong> and Ontario east to Pennsylvania,<br />
New York, and Vermont.<br />
