Relations of small mammal populations to even-aged shelterwood systems in sub-boreal spruce forest
Article Abstract:
Regeneration of cutover forest lands and the need to integrate nontimber resources have prompted studies of alternative silvicultural systems. A new study in southcentral BC tests the theory that a diverse shelterwood system would cut small mammal populations and investigates natural Douglas-fir seed production and the incidence of seed predation by small mammals. The study proves that natural regeneration can be successful despite seed predation and that shelterwood systems would provide diversity in the managed forestscape.

Silvicultural use of herbicide in sub-boreal spruce forest: implications for small mammal population dynamics
Article Abstract:
The hypothesis that herbicide-induced habitat alteration would reduce small mammal populations in early-successional stages of sub-boreal spruce forest was tested. Results showed that herbicide treatment reduced both shrub and herb volume, but herbaceous biomass returned to pretreatment levels by the second posttreatment year. This indicated that vegetation management treatments need to be applied as early as possible to achieve optimum control of competing vegetation and response of crop trees.

Relations of small mammal populations to even-aged shelterwood systems: a reply
Article Abstract:
Smith argues that Von Trebra et al's field experiment on shelterwood systems and small mammals did not meet research objectives. The effective trapping area was similar for deer mice and southern backed red voles among all grids, and this runs counter to predictions made by Smith. Other trends have also contrasted with Smith's forecasts. Researchers are welcome to challenge the results which have used data from studied carried out in realistic silviculture scenarios.
