What Is a Tree?
A tree is a perennial plant with a single woody stem, or trunk, supporting branches and leaves. Trees grow slowly, can live for centuries, and form the structural backbone of forests and urban green spaces.
Ecological and Economic Value
Trees absorb carbon dioxide, provide habitat, and regulate local climate. In finance, trees matter through timber markets, carbon credit programs, and ecosystem services that underpin sustainable investment portfolios.
Key Facts and Practical Uses
Common species include oak, pine, and maple, each with distinct wood properties. Trees are used in construction, paper production, and land management. For data on global forest resources, see FAO Forest Resources Assessment.
