Alders, scientifically known as Alnus, are deciduous trees found in the Northern Hemisphere. They have simple, serrated leaves and inconspicuous flowers in catkins that appear before the leaves.

The small cone-like fruits release winged seeds. Alder bark is initially smooth and gray, becoming rough as the tree matures. These trees thrive in wet areas, like riverbanks, and are known for nitrogen-fixing abilities.

Alder wood is lightweight and used in furniture. Common species include European alder, speckled alder, and red alder. They contribute to ecosystem stability and soil fertility.

The Botanical Description of Alder

1. Leaf Structure: Alder leaves are simple, alternate, and serrated, displaying an elliptical or ovate shape with a dark green color.

2. Bark Characteristics: The bark is initially smooth and greenish-brown, later developing fissures and turning reddish-brown as the tree matures.

3. Catkins and Flowers: Alder trees are dioecious, featuring long, pendulous male catkins and smaller, cone-like female flowers.

4. Cone Structure: Female catkins mature into woody cones or strobiles, distinctive in shape and essential for the tree’s reproductive cycle.

5. Size and Growth Habit: Moderate in size, Alders have a conical to cylindrical growth habit, making them suitable for landscaping and afforestation.

6. Root System: Alders exhibit nitrogen-fixing abilities through symbiotic relationships with bacteria in their root nodules, enhancing soil fertility.

7. Seasonal Changes: Deciduous in nature, Alders undergo seasonal changes, with dark green leaves turning yellow in autumn before falling off.

8. Adaptation to Wet Soils: Well-suited for wet soils, Alders thrive along riverbanks and in areas with high water tables, providing stability to riparian ecosystems.

The Geographic Distribution of Alder

1. North America: Alder species are widespread from the southern United States to northern Canada, particularly in riparian areas.

2. Europe: Native to Europe, Alders are found from the British Isles to Eastern Europe, commonly in mixed deciduous forests and along water bodies.

3. Asia: Alders thrive in diverse Asian habitats, from the temperate forests of Siberia to the deciduous woodlands of Japan.

4. Africa: While less common, Alders can be found in northern parts of Africa, often growing in mountainous areas.

5. South America: Alder species contribute to biodiversity in South America, especially in Andean regions and mountainous areas.

6. Australia: Introduced in certain regions, Alders are cultivated for environmental restoration projects, despite not being native.

7. New Zealand: Present in both North and South Islands, Alders are often seen in wetland areas, contributing to ecological balance.

The Chemical Composition of Alder

1. Tannins: Alder bark contains tannins, providing astringent properties for protection against herbivores and insects.

2. Flavonoids: Found in Alder leaves, flavonoids have antioxidant properties, aiding in the plant’s defense against oxidative stress.

3. Alkaloids: Some Alder species contain alkaloids, nitrogen-containing compounds with unclear functions in the plant’s biology.

4. Essential Oils: Certain Alder species produce essential oils, contributing to the overall olfactory characteristics of the tree.

5. Phenolic Compounds: Alders contain phenolic compounds, including phenolic acids, with antioxidant properties for pathogen resistance.

6. Betulin and Betulinic Acid: Alder bark contains betulin and betulinic acid, known for their anti-inflammatory and cytotoxic properties.

7. Lignin: Alder wood is rich in lignin, a complex polymer providing structural support and enhancing wood durability.

8. Nitrogen-Fixing Bacteria: Alder root nodules host nitrogen-fixing bacteria, crucial for atmospheric nitrogen fixation and soil fertility.

9. Resins: Alder trees produce resins as a protective mechanism, deterring herbivores and contributing to overall resilience.

10. Quinones: Some Alder species contain quinones, organic compounds with diverse properties, possibly influencing ecological interactions and environmental responses.
