Habitat Overview Thickets of New Jersey Tea and symbionts.

New Jersey Tea is found widely across the state in fairly dry, upland stands of hardwoods, particularly along edges and light gaps. It is a favorite food of deer and has been greatly reduced in many areas due to the build-up of the deer herd in absence of predators.

Many of the insects that feed on New Jersey Tea appear to have been formerly much more widespread than they are now, possibly due to the effects of deer over-browsing.

Related NHP Natural Communities Ceanothus americanus is listed as a regular or important constituent of the following Natural Community type: Ultramafic Outcrop Barren (Virginia Pine Subtype), Pine/Scrub Oak Sandhill (Mesic Transition Subtype). It is also found in number of other dry-xeric communities, including both hardwood and pine dominated forests. One large occurence has been recorded within a stand of Mesic Pine Savanna (Little River Subtype).
