Deciduous forest
A deciduous forest is a woodland dominated by trees that shed their leaves seasonally, often in response to cold or dry conditions.
Leaf senescence: The regulated aging process through which leaves break down and are eventually shed. Shortening days and changing temperatures trigger the annual transition from green canopy to leaf fall.
Temperate climate: A climate with moderate temperatures and seasonal variation, typically between tropical and polar regions. Many deciduous forests occupy temperate regions with warm growing seasons and cold winters.
Forest carbon cycle: The movement and storage of carbon among forest vegetation, soils, and the atmosphere. Deciduous trees store carbon in wood and soils, then exchange carbon seasonally through growth and decay.
Eastern North American deciduous forests: Temperate forests across eastern North America, dominated by broad-leaved trees that shed their leaves. Their maples, oaks, and beech trees illustrate a widespread temperate forest type.
Photoperiodism: A biological response to recurring changes in the length of day and night. Day length helps many trees time autumn growth cessation and leaf senescence.
Seasonality: Regular changes in environmental conditions over the course of a year. Seasonal shifts in temperature and water availability organize forest growth and dormancy.
Forest management: The planning and practice of maintaining, harvesting, or restoring forests. Management choices shape timber supply, habitat, regeneration, and resilience in deciduous woodlands.
European temperate broadleaf forests: Temperate forests of Europe dominated by broad-leaved trees, including oak, beech, and hornbeam. These forests show how deciduous communities vary with European climate and land use.
Abscission: The controlled separation of a plant part, such as a leaf, from the rest of the plant. A specialized separation layer releases leaves from branches in autumn.
Forest soil: Soil shaped by forest vegetation, organisms, climate, and accumulated organic matter. Leaf litter and root activity build the soils on which forest vegetation depends.
