Whereas such a lot efforts at biodiversity conservation have concentrated totally on secure components and reserves, the unprotected lands surrounding these parts - the "matrix" - are both very important to holding international biodiversity and keeping wooded area well-being. during this quantity, best woodland scientists David B. Lindenmayer and Jerry F. Franklin argue that the conservation of woodland biodiversity calls for a accomplished and multiscaled process that incorporates either reserve and non-reserve parts. They lay the principles for the sort of method, bringing jointly the most recent medical details on panorama ecology, forestry, conservation biology, and similar disciplines as they study: the significance of the matrix in key components of ecology resembling metapopulation dynamics, habitat fragmentation, and panorama connectivity; normal ideas for matrix administration; utilizing typical disturbance regimes to steer human disturbance; landscape-level and stand-level parts of matrix administration; the position of adaptive administration and tracking; and social dimensions and tensions in imposing matrix-based woodland administration.

Threshold theory ignores the critical role of some (often small) areas of a landscape for the persistence of biodiversity. For example, the limited area of riparian systems can be essential for a large amount of the bio- 2. , Mac Nally et al. 2000), and degradation of this habitat can have impacts highly disproportionate to their areal extent (see Chapter 6). Similarly, specialized habitats like cave systems can be small but support an important and often unique component of the endemic biota of a region (Culver et al.
14 I. 9. The matrix is the source of most commodities, such as wood, and services, such as well-regulated flows of highquality water. Maintaining long-term productivity of such lands and their ability to maintain natural levels of hydrologic and geomorphic processes is critical (managed forest landscape in Olympic State Experimental Forest, Washington, United States). Photo by J. Franklin. their own sake (Simberloff 1998). This is why Conner (1988) recommended that organisms be conserved at functionally viable numbers to ensure their ecological “effectiveness” in the maintenance of ecosystem processes.
Howe et al. 1991). Second, patches and corridors (as traditionally deﬁned) are never uniform but rather are always characterized by withinpatch heterogeneity (Forman 1995). , Lindenmayer et al. 1993a, 1999b; Mac Nally et al. 2000; Sieving et al. 2000). In these cases, within-patch processes as well as between-patch processes can be important (Harrison and Taylor 1997). The simpliﬁcations in landscape models are understandable given the complexity of real landscapes and the difﬁculty ecologists face in tackling such complexity.
