Special hunts, sharpshooting programs, and fertility control efforts have been implemented in residential communities to reduce local deer populations. For these management strategies to be effective, it is important to understand deer movement and behavior patterns in suburban lan...

This paper presents empirical evidence on the relationship between forest tenure and investment in silviculture. Silvicultural activities and expenditures on a large number of recently logged tracts in British Columbia, under four distinct forms of tenure, are assessed using a silvicultural investment model based on the conventional theory of capital. The empirical results indicate that silvicu...
