Varieties: none

Description

N. sylvatica is a perennial tree of the Cornaceae family native to North America and Canada. [1]

Distribution

N. sylvatica is found in the southeastern corner of the United States from Texas to Maine, as well as the Ontario region of Canada. [1]

Ecology

Habitat

N. sylvatica proliferates in dry or mesic upland forests, less commonly in bottomlands, pine savannas, or upland depressions, where occasionally inundated briefly. [2] Specimens have been collected from residential areas, upland open woodland, mixed upland hardwoods, floodplain of creek, mesic wooded bluff, flatwoods, shores of lake, river floodplain, live oak stand of cypress depression, edge of small pond, slash pine flatwoods, wet hammock, cypress-gum pond, and pine woodland. [3]

Phenology

N. sylvatica has been observed flowering February through May. [4] It is also a relatively shade-tolerant species. [5]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates. [6]

Fire ecology

N. sylvatica is not fire resistant and has low fire tolerance. [1]

Use by animals

N. sylvatica has medium palatability tp browsing animals. [1]
