Many mature forests in north-central BC are rapidly being converted to early seral plantation. Concomitant declines in some regional moose densities, coupled with observations of apparent starvation from collared females, suggest that bottom-up factors influence populations even in systems with predators. The nutritional value of five moose food plants in relation to the architecture of anthropogenic disturbances are presented. Concentrations of digestible protein generally declined in large openings compared to cut-block edges and forest understories. Habitat-specific allocation of anti-herbivory defenses in plants (tannins and secondary compounds) may render the available protein in some species below the maintenance requirements for moose. The effects of large-scale landscape changes in BC's interior forests are discussed in relation to wildlife.

The Natural Resources & Environmental Studies Institute (NRESi) at UNBC hosts a weekly lecture series at the Prince George campus. Anyone from the university or wider community with interest in the topic area is welcome to attend. Presentations are also made available to remote participants through Livestream (Channel 1). Go to http://www.unbc.ca/nres-institute/colloquium-webcasts to view the presentation remotely.
