Definition
The tree line, also called the timber line, is the edge of the habitat where trees can no longer grow. This limit is usually due to environmental factors like temperature, moisture, or soil conditions at high altitudes or latitudes. 🌲Beyond the tree line, you typically find only smaller plants like shrubs and grasses. It marks a distinct transition from forested areas to more open landscapes. The tree line isn't always a sharp, defined edge but can sometimes be a gradual thinning of trees.
