Forest fragmentation

Forest fragmentation is breaking large, contiguous forested areas into smaller forest patches, separated by roads, agriculture, utility corridors or other anthropological developments.

Fragmentation is one of many factors that threaten forest health and vitality. Large and intact forest ecosystems are essential to maintaining a good forest condition and biodiversity. Increased fragmentation means that the forest area in the largest patch sizes will decrease and that the small size classes will increase.
