Description
C. florida is a perennial shrub/tree of the Cornaceae family native to North America and Canada. [1] It is a smaller and bushier tree that reaches heights of 40 feet with a diameter between 12 and 18 inches.[2] Bark is grayish brown, reddish brown, or black, rough, broken into square blocks; leaves deciduous, opposite, simple, nearly hairless and smooth to touch on upper surface, finely hairy on bottom surface; inflorescence is many flowers crowded into a head, subtended by 4 large and showy white-pink petal-like bracts; fruit is an elliptical drupe, 1-2 seeded, bright red or yellowish at maturity, usually several are crowded together. [3]
Distribution
C. florida is native to the eastern continental United States west to Indiana, Missouri, Kansas, Oklahoma, and Texas, as well as the Ontario region of Canada.[1] It is also native in montane northeast Mexico, including Veracruz and Nuevo Leon.[4]
Ecology
Habitat
C. florida can be found in a range of habitats from dry to moist forests to wetlands.[4] It well in understories in the communities that it is found.[5]C. florida also proliferates in disturbed areas and rich woods.[6] Other habitats include bluffs and ravines, floodplains, gum swamps, and old-field communities.[7] It is listed as a facultative upland species, where it mostly occurs in non-wetlands, but can still occur in wetlands.[1] The species grows best on rich and well-drained soils that are usually on middle and lower slopes.[2]
Phenology
C. florida has been observed flowering from February to April, October, and November. [8] C. florida is a bird-dispersed species. [9]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates. [10]
Fire ecology
C. florida is not fire resistant, but has a medium fire tolerance. [1]
Use by animals
C. florida consists of approximately 5-10% of the diet for large and small mammals, water birds, and terrestrial birds.[11] It is a food source during the winter and fall for the fox squirrel and grey squirrel, cedar waxwing, bobwhite quail, flicker, cardinal, robin, mockingbird, woodpecker, and wild turkey. The twigs and the leaves are eaten by white-tailed deer, and it is not an important plant for nesting.[2] As well, beavers and rabbits browse on the sprouts and leaves of the plant, and the tree provides shelter and various habitat for many wildlife species.[7] For humans though, the fruit is poisonous, but other portions of the plant have been used in the past. Historically, Native Americans used the root bark as a skin astringent, fever reducer, a pain reliever for various ailments, an antidiarrheal agent, and to even counteract many poisons as well as a general tonic. The bark itself was used for a throat aid, headaches and backaches, and as an infusion for some childhood diseases like measles. The flowers were utilized for fever reductions and colic pain relief. Finally, compound infusions of various parts of the plant were used as medicine for blood diseases and as blood purifiers.[7] In modern times, the wood of C. florida is harvested for charcoal, tool handles, hayforks, wheel cogs, and pulleys, and it is sometimes utilized for specialty items like golf club heads or knitting needles.[7]
Diseases and parasites
C. florida has been impacted since the 1980s by widespread infection by the dogwood anthracnose fungus (Discula destructive).[4] Other pests and diseases include several wood boring insects and canker diseases that invade the main stem, and others that can attack the leaves and branches of the plant.[2]
Conservation and Management
C. florida is listed as endangered by the Maine Department of Conservation Natural Areas Program, exploitably vulnerable by the New York Department of Environmental Conservation, Division of Land and Forests, and threatened by the Vermont Department of Fish and Wildlife Nongame and Natural Heritage Program. [1] For timber stand improvement and tree harvest operations, 5 to 6 dogwoods should be left per acre for aesthetic purposes as well as a food source for wildlife.[2]
Cultivation and restoration
This species can be used in restoration efforts for urban forestry projects and even restoration of abandoned strip mines since C. florida is a soil improver due to the leaf litter decomposing quicker than most other species it associates with.[7]
