Habitat and Ecology [top]

Habitat and Ecology:This species occupies the cool maritime and partly mountainous NE of the USA, where it occurs from sea level in the north to nearly 1,400 m in the southern Appalachians. It grows on shallow sandy or gravelly soils poor in nutrients, usually well drained, but sometimes water-logged, as in the swamps of New Jersey. It is a seral species, most commonly associated with oaks (Quercus spp.) or with other pines e.g. P. virginiana, P. echinata, or P. pungens. In swamp areas it grows with Chamaecyparis thyoides. On some sandy sea shores (e.g. at Cape Cod, Massachusetts) a decumbent, wind-swept form 1-5 m tall occurs. It is exceptional in its capacity to resprout from stumps; small tufts of adventitious foliage appear on the trunks even of healthy trees. Its ability to regrow foliage after severe damage at any stage in its development enables this species to survive fires as well as browsing of seedlings and saplings. In areas with regular occurrence of fire many trees are multi-stemmed from a basal stool.
Continuing decline in area, extent and/or quality of habitat:No
Generation Length (years):30

Use and Trade [top]

Use and Trade: The wood of Pitch Pine is coarse and resinous, of small or moderate size and often not straight for any considerable length except in planted and well maintained stands. It is therefore of limited commercial value, used mainly for rough construction. ['Pitch Pine' in the timber trade may refer to P. palustris instead of this species.] The high resin content makes it decay resistant, a property which was made use of in past ship building and more recently railway sleepers. If 'destructively' distilled it yielded naval stores i.e. turpentine and related chemicals, also important in times of wooden ships. It now finds more use in charcoal burning. The adaptability of this pine to poor soil conditions makes it suitable for replanting of wasteland. It is of some interest in horticulture because of its tufts of foliage on the stem and its persistent cones, but usually confined to the arboreta and pineta of botanic gardens and private collectors, and only a few cultivars are known. Its resprouting from epicormic buds make it ideal for bonsai culture.
