lehtpuude

Lehtpuude, known in English as deciduous trees, are a group of trees and shrubs characterized by their seasonally shedding leaves. Unlike conifers, which retain needle-like leaves year-round, lehtpuude typically lose their broad, flat leaves during the autumn, entering a period of dormancy in winter. This process, called abscission, helps the trees conserve water and survive adverse weather conditions.

Deciduous trees are found in many temperate and subtropical regions around the world. They play a significant role in their ecosystems by providing habitat and food for various animals, including insects, birds, and mammals. Their leaves, when fallen, contribute organic matter to the soil, enriching it and promoting nutrient cycling.

Common examples of lehtpuude include species such as oak (Quercus), maple (Acer), birch (Betula), and elm (Ulmus). These trees are valued for their aesthetic appeal, especially in autumn when their leaves change color, creating vibrant displays of red, yellow, and orange.

Lehtpuude are also important economically, providing timber, pulp for paper production, and ornamental value. They require specific climatic conditions to thrive, including sufficient rainfall and a distinct seasonal cycle. Management and conservation of deciduous forests are vital for maintaining biodiversity and ecological health.

Overall, lehtpuude are vital components of many terrestrial ecosystems, contributing to environmental stability, biodiversity, and human well-being through their ecological and economic benefits.
