This woodlot is entirely forested but for a few open clearings. Clearings can always be found about the dead butternut stands, which one can assume were created by the juglone toxin produced by the butternut trees when still living. I am looking for sites to plant the red oaks that have germinated. Red oaks are partially shade tolerant so clearings are ideal for planting. The question then is if the oaks are tolerant to the juglone toxin which apparently they are. According to http://pubs.cas.psu.edu/FreePubs/pdfs/xj0039.pdf the following list of trees are resistant to juglone toxin. So far 60 acorns have germinated and to date I have planted 52 in various clearings.
Most maples except silver maple (Acer spp)
Eastern Red Cedar (Juniperus virginiana)
Serviceberry, Shadblow (Amelanchier)
Yellow Poplar (Liriodendron tulipifera)
River Birch (Betula nigra)
Hickory (Carya spp)
Virginia Pine (Pinus virginiana)
Black Cherry (Prunus serotina)
Flowering Dogwood (Cornus florida)
Oak species (Quercus spp)
Dogwood (Cornus alternifolia)
Staghorn Sumac (Rhus typhina)
Hawthorne (Crataegus spp)
Black Locust (Robinia pseudoacacia)
American Beech (Fagus grandifolia)
Arborvitae or Eastern White Cedar (Thuja occidentalis)
White Ash (Fraxinus americana)
Canada Hemlock (Tsuga Canadensis)
Honeylocust (Gleditsia triacanthos)
American Elm (Ulmus americana)
Carolina Silverbell (Halesia caroliniana)
Blackhaw Viburnum (Viburnum prunifolium)
