Landscapes are changing environments. Conservation of the amenities associated with landscapes must take into account the tendency of a landscape to change over time. Change is considered to be influenced by both cultural land use practices and natural resource processes which act on the landscape. A technique is developed which demonstrates an approach to measure the stability of landscapes. This approach also provides a means to qualify the importance of the elements which make up the landscape, thus defining the matrix of the landscape. A case study of the San Pedro National Conservation Area is used to demonstrate the technique. Sampled at three intervals 1935, 1973 and 1986 the landscape is shown to be stable, identifying this area with intrinsic value for conservation. Landscape scale assessments are shown to be inappropriate for ecosystem scale changes.
