Summary

Did you know?

What are heath species? A heath species is a member of the plant family Ericaceae, which includes the widely familiar blueberry and cranberry species (Vaccinium spp.). Many heath species are well-adapted to thrive under harsh environmental conditions, including excessively dry or wet soils, and low nutrient availability. In addition, some heath species can endure harsh winters and damaging ice. Common heath species of pitch pine-oak-heath woodlands include lowbush blueberry (Vaccinium angustifolium, V. pallidum), black huckleberry (Gaylussacia baccata), and bearberry (Arctostaphylos uva-ursi).

State Ranking Justification

There are less than a hundred occurrences statewide. A few documented occurrences have good viability and very few 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-heath woodlands are threatened by fire suppression.

Short-term Trends

The number and acreage of pitch pine-oak-heath woodlands in New York have probably declined slightly in recent decades due to fire suppression, disturbance by off-road vehicles, trash dumping, and development.

Long-term Trends

The number and acreage of pitch pine-oak-heath woodlands in New York have probably declined substantially from historical numbers due to fire suppression, fragmentation, disturbance by off-road vehicles, trash dumping, and development.

Conservation and Management

Threats

As a fire-dependent natural community, the primary threat to pitch pine-oak-heath woodlands is the suppression of fire. Other threats to this community include development (e.g., residential and commercial development, roads), recreational overuse (e.g., ATVs, hiking trails) and habitat alteration (e.g., excessive logging, construction of utility ROWs). A few examples of pitch pine-oak-heath woodland are threatened by invasive species, such as Japanese barberry (Berberis thunbergii) and black locust (Robinia pseudoacacia). 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 prescribed 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.

Development and Mitigation Considerations

Soils are very thin within this community, and the effect of clearing and construction on soil retention and erosion must be considered during any development activities. These soils are also acidic and nutrient-poor, and any soil enrichment contamination (e.g., from septic leach fields or fertilized lawns) can alter community structure and function. The open structure of this community is maintained by fire and presents a fire hazard to existing and proposed development. Unprotected structures located within or near this community are more susceptible to damage from fire.

Inventory Needs

Continue searching for large sites in good condition (A- to AB-ranked).

Research Needs

Research the composition of pitch pine-oak-heath woodlands on Long Island in order to characterize variations. Determine the optimal fire regime for this community. Further research is needed on the role that frost pockets play in maintaining this community.

Identification Comments

General Description

A pine barrens community that occurs on well-drained sandy soils in eastern Long Island (and possibly on sandy or rocky soils in upstate New York). The structure of this community is intermediate between a shrub-savanna and a woodland. This community is adapted to periodic fires; the fire frequency has not been documented, but it probably burns less frequently than pitch pine-scrub oak barrens (i.e., more than 15 years between fires).

Characters Most Useful for Identification

A pine barrens community with a shrub layer dominated by scrub oaks, which often form dense thickets. These scrub oak thickets comprise 40 to 70% of the community. Pitch pine (Pinus rigida) and white oak (Quercus alba) are the most abundant trees, forming a canopy with 30 to 60% cover. The shrub layer is dominated by scrub oaks (Quercus ilicifolia, Q. prinoides), and includes a few heath shrubs. Plants occupying the woodland floor include bearberry (Arctostaphylos uva-ursi), heathers (Hudsonia ericoides, H. tomentosa), and Pennsylvania sedge (Carex pensylvanica).

Elevation Range

Known examples of this community have been found at elevations between 20 feet and 1,369 feet.

Best Time to See

The heather species and bearberry come into bloom in early summer, and later, the lowbush blueberry species come into fruit, providing a tasty snack.

Similar Ecological Communities

  • Pitch pine-heath barrens (guide)
    Pitch pine-heath barrens is a shrub-savanna community that has a very open canopy and an extensive shrub layer dominated by heath species and sweet fern (Comptonia peregrina). It can have a more open canopy than pitch pine-oak-heath woodlands, and often has a more diverse species composition.
  • Pitch pine-oak forest (guide)
    Pitch pine-oak forests are mature closed-canopy forest communities. Conversely pitch pine-oak-heath woodland communities have a vegetation structure that is intermediate between a woodland and a shrub-savanna, with a canopy cover that does not excede 60%.
  • Pitch pine-oak-heath rocky summit (guide)
    Pitch pine-oak-heath rocky summits occur inland on rocky soils, often on rocky outcrops on summits, ridges, and slopes. Pitch pine-oak-heath woodlands, in contrast, occur on well-drained sandy soils in the pine barrens regions of the coastal plain.
  • Pitch pine-scrub oak barrens (guide)
    Pitch pine-scrub oak barrens is a shrub-savanna community that has a very open canopy and an extensive shrub layer dominated by scrub oaks and sweet fern. Within the shrub thicket, there are openings that are dominated by grasses, such as big bluestem (Andropogon gerardii), and Indian grass (Sorghastrum nutans). Pitch pine-oak-heath woodlands can have a more extensive canopy than pitch pine-scrub oak barrens, and they have a lower species diversity and lack the grass-dominated openings.

This figure helps visualize the structure and "look" or "feel" of a typical Pitch Pine-Oak-Heath Woodland. Each bar represents the amount of "coverage" for all the species growing at that height. Because layers overlap (shrubs may grow under trees, for example), the shaded regions can add up to more than 100%.
