limiting planting and herbicide treatment to sites that are most productive 

 for timber production; and leaving less productive sites to follow natural 

 succession. 



In agricultural areas large fields with a minimum of edge should be avoided; 

 hedgerows and natural vegetation in corners and damp spots should be 

 encouraged; and some crops should be left unharvested (i.e., corn or alfalfa) 

 as food. Effective means of biological control should be used to minimize 

 spraying of pesticides. 



The opportunity for managing mammals is perhaps greatest in developed areas. 

 Leedy and his colleagues (1978) have written an excellent guide to wildlife 

 management in urban and suburban areas. They stress the importance of 

 considering wildlife in the planning stages but also give management 

 recommendations for existing developed habitats. These include: attempt to 

 maintain entire ecosystems; use native plants for ornamental plantings; allow 

 as many trees as possible, both alive and dead; provide multilayered habitats 

 as opposed to monocultures; use natural drainage systems; avoid filling and 

 dredging wetlands; provide continuous lanes of vegetation between parks; plan 

 roads to minimize habitat loss; convert vacant lots to small parks or refuges; 

 provide a diversity of plant species; consider biological control over 

 pesticides; and, above all, retain natural habitat whenever possible.
