Summary

Did you know?

The pitch that was produced from pitch pine (Pinus rigida) sap was used to seal seams in ships and preserve wood during the American colonial period. The pitch can be obtained by scraping it off the tree in areas that have been wounded naturally, or by cutting marks along the tree's bark. Therefore, unlike other pines, few pitch pines were logged during this time period. If the cuts were made infrequently, the tree was not damaged.

State Ranking Justification

There are about a hundred occurrences statewide (number and acres may be artificially elevated by development fragmentation and broad classification). Several documented occurrences have good viability and several are protected on public land or private conservation land. This community has a restricted statewide distribution (correlated to pine barrens and sandy soils). Most examples are moderate in size and a few are high quality. Several pitch pine-oak forests are threatened by fire suppression.

Short-term Trends

The acreage of pitch pine-oak forest in New York has probably declined slightly in recent decades due to fire suppression, disturbance by off-road vehicles, trash dumping, and development. The number of pitch pine-oak forests may have increased slightly from historical numbers as formerly large matrix examples were fragmented by development into numerous large and small patches.

Long-term Trends

The acreage of pitch pine-oak forests in New York has probably declined substantially from historical numbers due to fire suppression, fragmentation, disturbance by off-road vehicles, trash dumping, and development. The number of pitch pine-oak forests may have increased substantially from historical numbers as formerly large matrix examples were fragmented by development into numerous large and small patches.

Conservation and Management

Threats

As a fire-dependent natural community, the primary threat to pitch pine-oak forests is the suppression of fire. Other threats to this community include fragmenting development (e.g., residential development, roads), recreational overuse (e.g., ATVs, hikers, mountain bikes, trash dumping), and habitat alteration (e.g., excessive logging, construction of utility ROWs). Several examples of pitch pine-oak forest are threatened by invasive species, such as Japanese barberry (Berberis thunbergii), black locust (Robinia pseudoacacia), multiflora rose (Rosa multiflora), buckthorn (Rhamnus cathartica), Asiatic bittersweet (Celastrus orbiculatus), Japanese honeysuckle (Lonicera japonica), and garlic mustard (Alliaria petiolaris).The oak trees in pitch pine-oak forests may be threatened by the non-native spongy moth (Lymantria dispar) which is one of North America's most destructive forest pests. The spongy moth is known to feed on the foliage of hundreds of species of plants in North America but its most common hosts are oaks (Quercus spp.) and aspen (Populus spp.). Spongy moth populations are typically eruptive in North America; in any forest stand densities may fluctuate from near 1 egg mass per ha to over 1,000 per ha. When densities reach very high levels, trees may become completely defoliated. Several successive years of defoliation, along with other biotic and abiotic stress factors, may ultimately result in tree mortality (McManus et al. 1980, Liebold 2003 ). Southern pine beetle (Dendroctonus frontalis) is a bark beetle that infests pine trees, such as pitch pine, white pine, and red pine. Southern pine beetle is native to the southeastern United States, but its range has spread up the east coast to Long Island, New York in 2014. Natural communities dominated or co-dominated by pines would likely be most impacted by southern pine beetle invasion.

Conservation Strategies and Management Practices

Develop and implement presribed burn plans at appropriate sites. Reduce or minimize fragmenting features, such as roads, abandoned clearings, unnecessary trails, etc. Restrict mountain bikes and ATVs to designated trails and least sensitive areas, and prevent dumping of trash.

Management should focus on activities that help maintain regeneration of the species associated with this community. Deer have been shown to have negative effects on forest understories (Miller et al. 1992, Augustine and French 1998, Knight 2003) and management efforts should strive to ensure that regenerating trees and shrubs are not so heavily browsed that they cannot replace overstory trees. Encourage selective logging in areas that are under active forestry.

Development and Mitigation Considerations

Strive to minimize fragmentation of large forest blocks by focusing development on forest edges, minimizing the width of roads and road corridors extending into forests, and designing cluster developments that minimize the spatial extent of the development. Development projects with the least impact on large forests and all the plants and animals living within these forests are those developments built on brownfields or other previously developed land. These projects have the added benefit of matching sustainable development practices (for example, see: The President's Council on Sustainable Development 1999 final report, US Green Building Council's Leadership in Energy and Environmental Design certification process at http://www.usgbc.org/).

Inventory Needs

Survey for occurrences statewide to advance documentation and classification of pitch pine-oak forests. A statewide review of pitch pine pine-oak forests is desirable. Continue searching for large sites in good condition (A or B-ranked).

Research Needs

Research the composition of pitch pine-oak forests statewide in order to characterize variations (e.g., coastal plain, inland, and northern types). Collect sufficient plot data to support the recognition of several distinct pitch pine-oak forest types based on composition and by ecoregion. Determine the optimal fire regime for this community.

Range

New York State Distribution

Pitch pine-oak forests are primarily known from the Suffolk County portion of the Atlantic Coastal Plain where it historically occurred as a matrix forest associated with the Central Long Island Pine Barrens where large examples persist. Smaller examples of this community are also known from Hudson Valley Glacial Lake Plain and the outwash plains along Lake Champlain in Clinton County and probably Essex County. Within the Hudson Valley Glacial Lake Plain, pitch pine-oak forests are known from Albany County (Albany Pine Bush), Saratoga County (Saratoga Sandplains), and Warren County (Glen Falls Sandplain). Small patches may occur in the Mohawk River Valley and the hills of the Mid-Hudson River Valley in Rensselaer County. As more data are collected, the inland sites may be recognized as distinct communities separate from the coastal plain type.

Global Distribution

This broadly-defined community probably occupies only sandy outwash areas on the Atlantic and Saint Lawrence drainages of the northeastern United States. This range is estimated to extend northeast to southern Maine, northwest to northern Lake Champlain, New York, southeast to Cape Cod and the offshore islands of Massachusetts, and south through New Jersey and Pennsylvania, possibly to Delaware. Small examples are possible farther west around Lake Ontario (e.g., near Plessis Flat Rock, New York or near the Lake Ontario dunes of Ontario), or farther south in the central Appalachians.

Characteristic Species

Similar Ecological Communities

• Appalachian oak-pine forest (guide)
  Appalachian oak-pine forest communities are made up of any of the oaks present in pitch pine-oak forests, and usually white pine (Pinus strobus), which has a canopy percent cover of at least 25%. When pitch pine is present and abundant in this community, it is typically located on thin rocky soils.
• Coastal oak-heath forest (guide)
  Coastal oak-heath forest communities feature the same oak species as pitch pine-oak forests, but they have a very low percent cover of pitch pine (<1%) in the canopy. The two communities have similar understory species compositions.
• Pitch pine-heath barrens (guide)
  Pitch pine-heath barrens is a shrub-savanna community that has a very open canopy (with 30-60% cover), and an extensive shrub layer dominated by heath species and sweet fern (Comptonia peregrina). In contrast, pitch pine-oak forests are closed-canopy mature communities.
• Pitch pine-oak-heath woodland (guide)
  Pitch pine-oak-heath woodland communities are pine barrens communities of the coastal plain region that have a vegetation structure between a shrub-savanna and a woodland. The canopy of this community is more sparse than that of pitch pine-oak forests, and the understory has species characteristic of coastal plain barrens, such as bearberry (Arctostaphylos uva-ursi) and heathers (Hudsonia spp.).
• Pitch pine-scrub oak barrens (guide)
  Pitch pine-scrub oak barrens is a shrub-savanna community that has a very open canopy (with 20-60% cover), and an extensive shrub layer dominated by scrub oak and scrub chestnut oak (Quercus prinioides). In contrast, pitch pine-oak forests are closed-canopy mature communities.
