Native Trees

Trees

The Wabanaki-Acadian forest is mixture of coniferous and deciduous trees. Prince Edward Island has a large variety of native tree species, all fulfilling important roles in our ecosystem. These species have adapted for thousands of years for our climate and co-evolved with our other flora and fauna. They are beautiful, hardy, protect soil and waterways, reduce wind damage, and create habitat and food for animals among many other things. Below is a list of the native tree species found on Prince Edward Island.

CONIFEROUS TREES

Picea mariana

Rarity: S5 (secure)

Description: A small to medium sized, early- to mid-successional understory tree. It has short, square needles that grow in spirals on its branches and hug the twigs. More slender than white or red spruce. It has a blueish-green appearance. The crown on older trees is open and irregular, with slender drooping branches which turn up at the ends.  

Habitat: Black spruce grows throughout Prince Edward Island but is confined mainly to low, damp places, like bogs. 

Planting conditions: Can tolerate a wide variety of soil types. Well-suited to wetland plantings, or general forest restoration plantings.  

 

Picea glauca

Rarity: S5 (secure)

Description: A medium to large, early successional, understory or canopy tree. It can be very small when growing on the coast. White spruce has stiff, square-sided needles arranged in spirals on its branches. Its needles have a urine-like smell when crushed. Its branches do not droop like black or red spruce. Thicker and more robust in its trunk than black spruce.  

Habitat: Grows in full sun, in hedgerows, in old fields and along the coastline. 

Planting conditions: Plant in areas with full sun, will tolerate wind and coastal conditions. Good for windbreaks and hedgerows.

Picea rubens

Rarity: S5 (secure)

Description: A large, late successional canopy tree. Has short, square needles that grow in spirals and hug its branches. This is the characteristic species of the Wabanaki-Acadian forest. Its branches are well-spaced and curve upward at the ends, giving it a more drooping, softer silhouette than white spruce. 

Habitat: Red spruce grows in mixed wood stands, often along the sides of streams in deep, rich soil. It is found growing with hemlock, white pine, sugar maple and yellow birch in the climax Wabanaki-Acadian forest. 

Planting conditions: Often used in our restoration forestry work in patches and other woodland plantings.

Pinus strobus

Rarity: S5 (secure)

Description: A large, mid- to late-successional canopy tree. Eastern white pine is the only native pine with bundles of five needles. The needles have a blueish tinge and are quite long and flexible. The tops of older specimens often break off, giving them a flat-topped appearance.

Habitat: Eastern white pine grows on a variety of sites but does best on a moist, sandy soil. It can be found in mixed stands with red pine and is quite common in hardwood mixes with eastern hemlock. Older specimens can also be found along property lines.

Planting conditions: Used in our restoration forest plantings, such as in patches. Can be planted in dry areas with partial shade around homes and buildings, and in windbreaks and hedgerows.

Pinus resinosa

Rarity: S2 (imperilled)

Description: A medium to large, mid successional canopy tree. Red Pine has bundles of two long needles. They are stiff and pointed. Bark is scaly and often a reddish-brown. It develops into larger plates as it ages. 

Habitat: Red Pine occurs mainly in Murray River, Fort Augustus and New London. Its best development occurs on deep loamy sand or gravel, but it will grow on a large variety of sites. In Prince Edward Island it grows in pure stands also mixed with spruce and balsam fir.

Planting Conditions: Can be used in restoration work, and in areas in full sun (with sandy soils), around homes and buildings.

Pinus banksiana

Rarity: S2/S3 (imperilled/vulnerable)

Description: Small to medium, early successional understory tree. Its short needles are in bundles of two. Has a branchy and crooked trunk with a narrow, open crown of twisted branches. Its cones are crescent shaped and sharply curved. The Jack pine is adapted to survive in areas where there have been forest fires, with cones that will stay closed for many years until they reach the right temperature. 

Habitat: It is confined to small, scattered patches throughout the province, often growing in low-lying wet areas with black spruce. 

Planting conditions: Can be used in restoration work in old fields or other full-sun, poor conditions. 

Tsuga canadensis

Rarity: S3/S4 (vulnerable/apparently secure)

Description: A large, late-successional, canopy tree. Small, flat needles are attached to the stem by a small, string-like stalk. The ends of the branches droop, giving it a soft, lacy silhouette. It is a keystone species of the Wabanaki-Acadian forest. 

Habitat: Often found along streams, hemlock flourishes in areas of high humidity but without standing water. It grows best in rich, well-drained land, growing with yellow birch, sugar maple red maple, white pine and red spruce.

Planting conditions: Often used in our restoration plantings in forests because it is an old-growth species. Can be used in landscaping in sheltered, shady areas. Will not tolerate wind, full sun or standing water. 

Thuja occidentalis

Rarity: S3/S4 (vulnerable/apparently secure)
