General Information
Scientific Name: Acer saccharum Marsh.
Common Name(s): Sugar Maple, Hard Maple, Rock Maple
Family: Sapindaceae

Native Range:
Found primarily in the eastern part of North America, including the Maritime provinces, Ontario, Quebec, and parts of the northeastern U.S.
It grows in broadleaf forests, particularly in southern Ontario and Quebec.
[Map] Typically ranges from southern Ontario and Quebec to parts of New England and the Great Lakes region.

Introduced Range: No significant introduced range; native to North America.
Canadian Plant Hardiness Zones:
Zones CA4, NA3 (typically Hardy in colder climates).

Size & Growth:
Typical Height: 20–35 meters (66–115 feet)
Maximum Recorded Height: 45 meters (148 feet)
Trunk Diameter (Average & Max): Average trunk diameter: 40-60 cm
Maximum trunk diameter: 90 cm

Growth Rate: Medium to fast, depending on conditions.
Typical Lifespan: 150–200 years, occasionally up to 300 years.
Record Age: Over 300 years (rare).

Quick Recognition Features

Notable Leaf, Bark, Cone, or Twig Features:
Leaves: 5 lobes with blunt-pointed tips; green on top, pale and hairless beneath; turns yellow to brilliant orange and bright red in autumn.
Buds: Terminal buds are sharp-pointed, dark brown, and 6–12 mm long with 6–8 pairs of scales.
Bark: Smooth gray when young, becoming dark gray with vertical ridges and irregular scaly patterns as it matures.
Twigs: Shiny reddish-brown to green, hairless.

Reproduction & Life Cycle
Seed Maturity (Age at first seed production): Typically produces viable seeds after 40-50 years, though some trees may produce seeds earlier.
Reproductive Cycle: Seed production occurs most years, with abundant crops at intervals of 5–7 years.
Pollination Method: Wind-pollinated (anemophilous).
Seed Dispersal Mechanism: Wind dispersal (via paired keys).
Seed Dormancy Requirements: Requires cold stratification, usually germinating in the spring while snow is still on the ground.

Environmental Preferences
Soil Preferences: Deep, fertile, well-drained soils, often with some lime content. Can tolerate acidic soils, especially in regions with low lime.
Water Needs: Moderate to high; prefers moist environments but can tolerate dry conditions once established.
Drought Tolerance: Moderate to low; may suffer under extended drought.
Flood Tolerance: Low; sensitive to flooding, especially in the root zone.
Shade Tolerance: Tolerates heavy shade in early life, but prefers partial sunlight once established.
Root System Type: Deep, wide-spreading root system.
Climate Adaptability: Well-adapted to temperate climates, can endure colder temperatures of southern Ontario and Quebec.

Physical & Chemical Properties
Wood Density: 700-800 kg/m³ (44–50 lb/ft³)
Strength Rating: High, making it desirable for furniture and cabinetry.
Decay Resistance: Moderate to high; durable in dry conditions but susceptible to rot in wet environments.
Fire Resistance: Moderate; typically not fire-resistant but does not burn easily when dry.
Fire Regeneration Ability: Can regenerate after fire, especially from stump sprouts.

Ecological Role & Interactions
Wildlife Value: Provides food (sap and seeds) and shelter for wildlife. Important for birds, small mammals, and insects.
Companion Species: Grows alongside other broadleaf trees like Eastern White Pine, Eastern Hemlock, and various oaks and maples.
Invasive Status: Not invasive; native to its range.
Threats: Susceptible to air pollution, soil degradation, and diseases such as verticillium wilt. Climate change and drought may also impact growth and survival.

Human & Cultural Uses
Traditional Uses: Indigenous groups historically used the sap for food (maple syrup and sugar), and wood for tools and carvings.

Modern Uses
Timber for high-quality furniture, flooring, veneer, and cabinetry.
Maple syrup production (requires about 40 liters of sap to make 1 liter of syrup).
Wood is used in the production of cutting boards, toys, and turned woodenware.


Symbolism/Mythology
Canada’s national tree; its stylized leaf is featured on the Canadian flag.
The sugar maple is highly valued for its beauty and ecological importance, often symbolizing strength and endurance.

Additional Notes & Fun Facts
Unique Features: Known for its striking fall foliage, with brilliant yellow, orange, and red hues.
Interesting Historical Facts: The sugar maple is one of the most significant tree species in Canada due to its cultural and economic value.
Rare/Endangered Varieties: No endangered varieties are specifically noted for sugar maple, but it may face local threats from diseases and environmental stressors.
