Description: As the emergence of invasive pathogens and their impacts on ecological communities increases, so has the interest in understanding how landscape pattern (in other words the configuration and composition of suitable habitat) affects their establishment and spread. Plant pathogen invasions are inherently spatial, but few studies have demonstrated the role of landscape pattern on disease dynamics. In this study, we investigated two hypotheses: Does the spatial pattern of host habitat predict Phytophthora ramorum disease severity, and is this relationship scale-dependent?

Keywords: Scale, landscape pathology, connectivity, fragmentation.
