Node

Network structure

A landscape element or area within a network that provides a concentration of ecological capacity, resources, connections, or functions relative to the elements connecting it. A node is defined by its relationship to the network rather than simply by its size, shape, or habitat quality and may contain multiple blue or green elements and patches.
