As suburbia swells into wild country throughout the West, conflicts between humans and wildlife increase: Deer graze in gardens and dogs lope into the hills after packs of singing coyotes. Occasionally, a black bear wanders close to a subdivision or a mountain lion lunges for someone's pet. To keep such inevitable encounters as positive as possible, the Colorado Division of Wildlife has published a brief guide, Developing With Wildlife In Mind. It encourages planners to take wildlife into account when designing new communities so that conflict can be minimized. It also offers residents a few precautions for avoiding trouble with wild animals. Recommendations include clustering development to preserve large parcels of wildlife habitat, steering clear of riparian zones, landscaping with native plants and keeping trash away from scavengers.
