Conserving species in Carolinian Canada means not only protecting existing natural areas, but actively replacing habitat where we can. We can use this process of ecological restoration to enlarge natural areas and provide connections between them. We know that larger blocks of natural habitat are better than small ones, and connected blocks are better than isolated fragments. Individual gardeners can contribute to the restoration and stewardship of naturalized corridors by planting native species in their own yards.
A critical aspect of restoration is the use of native species; trees, shrubs, and herbaceous plants that are naturally adapted to their local area. Non-native plants are those from other parts of the world and North America that have been introduced, purposefully or accidentally, to Ontario. Non-natives often out-compete native plants and can be less adapted, over the long term, for survival in the landscape. Many are notoriously aggressive and persistent. The use of native plants encourages the conservation of the diversity of species that originally evolved in our region.
Another important principle to remember is that you should plant only specimens grown locally from native seedstock. It is vital to recognize that individual species exhibit a range of genetic characteristics; by planting non-local specimens you may be causing more harm than benefit in terms of conserving biological diversity. Another important thing; do not over-emphasize the planting of rare species. They occur only rarely in nature, and they should be equally rare in replanting projects. See the Carolinian Canada factsheet Sources of Native Planting Stock for the Carolinian Zone for more information.
The following list of nurseries were carefully selected as those providing, native, genetically appropriate, plant species.
Landowners planting trees are commonly limited by the planting stock that is available. Most often, reforestation is therefore done through planting coniferous species such as white pine, cedar, or white spruce. Today it is equally possible to reforest areas with deciduous species, provided that you are: replanting a relatively small area, and are prepared to maintain the planted trees individually for the first two to five years.
Start with the common deciduous species groups such as maple, ash, or oak. Be sure you are dealing with native species; avoid such varieties as Norway Maple. Then mix in some of the above listed Carolinian species to provide diversity. Some of these species might also be suitable specimen trees around your home or in your garden.
The most important principle to remember in this case is to ensure that you purchase only specimens grown locally from native seedstock, and that you do not over- emphasize the rare species. They occur only rarely in nature, and they should be equally rare in replanting projects. It is vital to recognize that individual species exhibit a range of genetic characteristics; by planting non-local specimens you may be causing more harm than benefit in terms of conserving biological diversity.
The following species are particularly rare, and should not be planted except under direction from a qualified botanist.Pin oak (Quercus palustris)
Dwarf chestnut oak (Quercus prinoides)
Blue ash (Fraxinus quadrangulata)
Big shellbark (Carya laciniosa)
Cucumber tree (Magnolia acuminata)
The Redbud tree (Cercis canadensis) is only known from one historic natural occurrence on Pelee Island, and is considered extirpated as a native species, but it is widely introduced as a 'Carolinian' species in home gardens, and is a beautiful species to plant with its small pink blossoms that appear in May before the leaves come out.

For additional information you may obtain The Society for Ecological Restoration's 2008 Native Plant Resource Guide for Ontario which is available for a cost of $5.00 from the Ministry of Natural Resources 1-800-667-1940 or the Society for Ecological Restoration (Ontario) website.
Listing of sources in this factsheet does not imply endorsement by the authors, or by the Carolinian Canada Program, nor does omission imply other sources are unsuitable.
Your local garden centres may also carry some of these species.
Your local conservation authority or Ministry of Natural Resources office may be able to provide information on tree planting programs and available nursery stock in your area. Be sure to check which species are available. The private nurseries may have a wider selection of stock.
Be careful to ensure that the species you select are appropriate for your property. For example, sassafras and shagbark hickory prefer high dry spots while sycamores and black walnuts will be found in floodplain areas. The black gum tree will appear in lowland sites with poor drainage alongside the black ash, swamp white oak, and cottonwoods.
Ask for advice when you purchase planting stock, and follow it!
