Dead trees, often referred to as snags, are trees that have lost their leaves and are no longer living. They can be identified by their dry, brittle branches and lack of green foliage. While they may appear lifeless, dead trees play a crucial role in the ecosystem by providing habitat and food for various wildlife, including birds, insects, and small mammals. As dead trees decay, they contribute to soil health by returning nutrients back into the ground. This process supports the growth of new plants and trees, making dead trees an essential part of the natural cycle. Their presence can also help prevent soil erosion and maintain biodiversity in forests and woodlands.
