Increasing housing density has negative effects on native biodiversity. This implies that we should build at low density to conserve native species. However, for a given human population, low-density development must cover a large area, resulting in sprawl. A pertinent question is then, at what housing density are the impacts of a given human population on native biodiversity minimized? We addressed this question with carabid beetles in Ottawa and Gatineau, Canada. First, we collected beetles at 22 sites representing a range of housing densities. We then used these data to estimate beetle abundance and species richness in hypothetical development scenarios representing the housing density/sprawl area trade-off. Our results suggest that clustering... |

Many communities on the urban fringe are implementing a range of policies to preserve farmland and open space, cluster residential development, and guide development to areas with existing infrastructure. These efforts are an attempt to control overall growth and the concomitant loss in open space and also to counter a trend toward the so-called large lot development that often takes place in these areas. Planners have argued that policies to manage density are the most important local policy focus for urban areas in the coming years. It is possible that large lot development and sprawl are themselves the result of government policy. Most local governments use zoning to establish minimum acreage requirements for each residential dwelling unit; in ex-urban... |
