One of the simpler, and more common natural pattern measurements is the size-class distribution of different types of patches on a given landscape. This metric is commonly applied to disturbances, but is also often used to describe the condition of old forest. For example, a 'natural' patch-size distribution for old forest is given below for an Upper Foothills landscape in west-central Alberta. The data in this case suggest that the majority of the area of old forest is accounted for by patches larger than 1,000 hectares, and old forest patches larger than 10,000 hectares are natural phenomena.
