A philosophy of habitat management for northern bobwhites

Article Abstract:

There has been much research into the management of northern bobwhites, and research results are evaluated to find patterns that could be meaningful in developing a general habitat management philosophy for the species. There is no firm evidence that food is limiting in the field, therefore average density will not be affected by practices aimed at improving food supplies. Research results are largely consistent with the hypothesis that an increase of usable space will increase the mean density of bobwhites. Therefore habitat management should aim to provide unrestricted use of space for bobwhites.

Slack in the configuration of habitat patches for northern bobwhites

Article Abstract:

Simple landscape modelling can be used to show the potential existence of different patch configurations leading to fully usable space. On this basis, optimal landscapes for northern bobwhites are structurally variable but functionally comparable. It therefore appears that landscapes have a property that can be defined as slack. In the presence of slack, it is possible to add or remove patch types and to alter their dispersion in space without affecting the nature of the probability surface linked with the landscape.
