Unformatted text preview: disturbance The pervasiveness of anthropogenic habitat modification is such that humans (even pre-industrial ones) can be considered "ecosystem engineers" that have had a dominant role in shaping many environments for thousands of years Anthropogenic disturbances are often the result of attempts to maintain or increase productivity of key ecological resources (i.e., a form of resource management) Peacock & Turner (2000:139) argue that this occurs at several scales: – Population management = enhance local populations of a resource species – Community management = create or maintain diversity of resource-rich locales or habitats – Landscape management = multi-habitat (large-scale)...
