Understanding Measures of Landscape Patterneffects of pattern on organisms. In order to investigate relationships between landscape pattern and ecological processes, it is often helpful to describe the patterns in quantifiable terms, and a variety of spatial metrics have been developed for this purpose (Whitcomb et al. 1981 Forman and Godron

A Spatial View of Population Dynamicsobservations (Ludwig and Reynolds 1988). Wildlife managers go through many formal and informal steps in managing the resources under their responsibility, starting with visualizing a population’s probable position on a logistics growth curve (Lotka 1925). For example, when an investigator claims: (1

Landscape Heterogeneity and Ungulate Dynamics: What Spatial Scales are Important?l known. Clearly, the spatial arrangement and density of vegetation influences the success of herbivores in finding food (Kareiva 1983 Risch et al. 1983 Stanton 1983 Cain 1985 Bell 1991). Theoretical studies suggest that organisms must operate at larger spatial scales (i.e., search a larger area) as

The Influence of Landscape Scale on the Management of Desert Bighorn Sheepton (1929) estimated there were approximately 2,000,000 bighorn sheep in the contiguous United States in pristine times; about half were desert bighorn sheep (Buechner 1960 Cooperrider 1985). However, Valdez (1988) doubted that wild sheep numbers ever exceeded 500,000 in North America. Bighorn sheep

Adaptive Policy Design: Thinking at Large Spatial Scales and maintenance of biodiversity. In this new policy environment, it is fair to say that there are no longer any reliable standard operating procedures and decision rules, so that every management decision and initiative should be viewed in some sense as an experiment with highly uncertain outcomes
