State Conservation Status Rank
S1
Critically Imperiled in New York - Especially vulnerable to disappearing from New York due to extreme rarity or other factors; typically 5 or fewer populations or locations in New York, very few individuals, very restricted range, very few remaining acres (or miles of stream), and/or very steep declines.
Global Conservation Status Rank
G5
Secure globally - Common in the world; widespread and abundant (but may be rare in some parts of its range).

Summary

Did you know?

This pine is named for the spiny bracts on the outside of the cones. It is well adapted to fire because its crook-shaped lower trunk sends up new shoots if the upper trunk is killed by fire (Wikipedia contributors).

State Ranking Justification

There is one small existing population. There were four populations from the late 1800s that no longer exist because their habitat has been eliminated but there's still one record from 1915 on Long Island that needs to be rechecked.

Short-term Trends

The short-term trend of the existing population is apparently stable.

Long-term Trends

This plant has always been very rare but populations have been reduced from the 1800s from 5 locations to one.

Conservation and Management

Threats

Trees may be suppressed by shading from taller surrounding vegetation if open-canopied conditions are lost.

Conservation Strategies and Management Practices

Maintain open-canopied conditions around the trees to allow the trees space to grow and reproduce.

Habitat

Habitat

The trees grow along the sandy trails and at the bottom of a sandy berm in wet deciduous woods (New York Natural Heritage Program 2012).

Associated Ecological Communities

  • Red maple-blackgum swamp (guide)
    A maritime, coastal, or inland hardwood swamp that occurs in poorly drained depressions, sometimes in a narrow band between a stream and upland. Red maple and blackgum are often codominant or blackgum may be the dominant tree. Pitch pine may occur on drier hummock islands in pine barrens settings.
  • Red maple-sweetgum swamp (guide)
    A hardwood swamp that occurs on somewhat poorly drained seasonally wet flats, usually on somewhat acidic soils. Red maple-sweetgum swamps often occur as a mosaic with upland forest communities. Sweetgum is often the dominant tree or may be codominant with red maple. Other codominant trees include pin oak and blackgum.

Range

New York State Distribution

Currently this pine is only known from Staten Island. The one historical population in Suffolk County is considered extirpated. There are also a few records of planted trees in Essex and Nassau counties and unconfirmed reports from Albany and Westchester counties.

Global Distribution

It is widespread throughout the southeastern US from New Jersey southeast to Missouri, Eastern Oklahoma and eastern Texas. It is scattered and rare from eastern Pennsylvania to Staten Island.

Identification Comments

General Description

Shortleaf pine is a medium tall tree with a short crown. The bark is reddish-brown (almost black when young), furrowed, and broken into large, scaly plates. The twigs are pale and whitish. The needles are usually 2 per bundle but sometimes 3. They are 7.5-12 cm long, slender, soft and flexible, sharp pointed, yellowish-green to dark bluish-green. The cones are oblong and taper near the tip, 3.8-6.3 cm long and dull brown. The scales have a sharp spine in the middle. They open at maturity and persist for several years (Gleason and Cronquist 1991).

Best Life Stage for Proper Identification

This pine can be identified at any time of the year.

Similar Species

Virginia pine looks very similar but its leaves are always two per bundle and 4-7 cm long (yes, shorter than those of shortleaf). The twigs are purplish brown or purplish gray waxy. The cone may be a little more reddish (Gleason and Cronquist 1991).

Best Time to See

The trees and their persistent cones are visible any time of year.
