evergreen trees

Evergreen trees are types of trees that retain their needles or leaves year-round, instead of shedding them seasonally like deciduous trees. Examples include pine, spruce, and fir. Their persistent foliage allows them to photosynthesize continuously, even in winter. These trees often have adapted needle-shaped leaves with a waxy coating to conserve water and withstand cold. Evergreen trees provide lasting habitat and beauty in landscapes, and their wood and sap are valuable resources. They play an important role in ecosystems by stabilizing soil, supporting wildlife, and contributing to air quality.
