The primary objective of this chapter is to describe standardized methods for measur¬ing and monitoring attributes of landscape pattern in support of habitat monitoring. This chapter describes the process of monitoring categorical landscape maps in which either selected habitat attributes or different classes of habitat quality are represented as different patch types, using maps produced by the modeling approaches described in chapter 5. Although many alternative models of landscape structure exist, such as landscape gradi¬ents (McGarigal and Cushman 2005) and graph models (Urban et al. 2009), we focus on categorical landscape maps because of their familiarity to managers, long history of use in landscape ecology, and the fact that land management agencies largely base planning and analysis on this kind of representation of landscape structure (McGarigal et al. 2009). The salamander habitat monitoring plan in chapter 10, however, provides an example of a graph model (i.e., a model of habitat connectivity for metapopulation structure).
