Characteristics of Alder Trees

Alder trees are deciduous trees found in various parts of the world. Here are some key characteristics of these fascinating trees:

  • Leaf Shape: Alder trees have oval-shaped leaves with toothed edges.
  • Bark Texture: The bark of alder trees is smooth when young and rough and wrinkled as they mature.
  • Fruit: They produce cone-like fruits called catkins that contain seeds.
  • Soil Preference: Alder trees thrive in moist, nutrient-rich soils, often found near streams or wetlands.
  • Nitrogen Fixation: These trees have a unique ability to fix nitrogen from the air into the soil, enriching it for other plants.
  • Growth Rate: Alder trees are known for their rapid growth and can reach heights of 50 to 80 feet.
