native vegetation for biodiversity. These can include reducing grazing pressure,
retaining dead trees, shrubs and surface rocks, making remnants larger (e.g.
through enhancement planting or strategic fencing) and controlling weeds.
Woodland remnants can be managed for different purposes and in response to
different objectives (see Box 1.2 in Chapter 1). In some cases it will be important to
prioritise which remnants will be the most appropriate ones for management. For
example, it may not be appropriate to target large remnants in good condition
because there is less to improve and hence little to be gained from additional
management effort. Conversely, some kinds of degraded remnants like those on
highly productive valley floors and in riparian areas may be more valuable to focus
on for management interventions. This is because they may improve markedly
through actions like fencing, reduced grazing pressure and weed removal. They
also may be the places subject to the greatest threats of ongoing degradation.
Developing priorities for management will often be best done through a farm plan
- a topic we visit in the final chapter of this topic (see Chapter 7).
