In a recent review, David Lindenmayer and a long list of distinguished
conservation biologists review two decades of research on landscape
management [3]. They identify a set of 13
factors that anyone managing a landscape for conservation should
consider, and they group those factors under four boad themes: setting
goals, spatial issues, temporal issues, and management approaches.
- Setting goals
- Develop long-term shared visions and quantifiable objectives.
- Spatial issues
- Manage the entire mosaic, not just the pieces.
- Consider both the amount and configuration of habitat and
particular land cover types.
- Identify disproportionately important species, processes, and
landscape elements.
- Integrate aquatic and terrestrial environments.
- Use a landscape classification and conceptual models
appropriate to objectives.
- Temporal issues
- Maintain the capability of landscapes to recover from
disturbances.
- Manage for change.
- Time lags between events and consequences are inevitable.
- Management approaches
- Manage in an experimental framework.
- Manage both species and ecosystems.
- Manage at multiple scales.
- Allow for contingency.
That set of factors pretty well covers the issues conservation
managers have to consider, but there's one task for conservation
managers that neither this list nor our discussion so far has dealt
with explicitly--designing a conservation reserve system.
