Caribou food production in the habitat Vegetation species cover % Leaf Aare Index; Biomass; Green-up date Climate & land use scenarios Caribou carrying capacity of the habitat Ecosystem model Ecotrophic Efficiency; Annual consumption of summer & winter diets by an “average” caribou; Lichen damage by caribou trampling; Consumption by other wildlife species Caribou herd size Optimal caribou harvest rate Foliage : stem ratio; Foliage turnover rate; Photosynthetic capacity Field measurement + remote sensing + modeling integration “Food Availability”

10. Commitment  Our team is committed to revise and implement work plan according to CARMA partners’ needs, so that our works will be supportive and complementary to CARMA partners  ESS-NRCan, through the Climate Change Program, is committed to provide necessary A-base funding (salary and O&M) for this work over the next 3 years  Our team has the full support of ESS-NRCan, through the Climate Change Program, to become a CARMA partner and to fulfill all related responsibilities of a CARMA partner
