Landscape management
Ecological landscapes are patchy and contain a variety of habitats. Some ecological problems can be addressed
at the scale of a single patch - a solitary agricultural fi eld or marine reserve. But others require managers to
focus at the much larger scale of multiple patches and habitats in regional landscapes and waterscapes.

Key concepts
In this chapter you will
see that populations often exist as linked subpopulations in a metapopulation - conservation then
requires attention to the size and number of subpopulations and interlinking corridors
realize that the effectiveness of a pest control program may be compromised by the make-up of
the surrounding landscape matrix
