Browse Control

For more than 20 years, BNZ scientists have studied the hidden impact of browsing on ecosystems by conducting experiments that exclude moose and snowshoe hare from large areas. Results show that browsing controls which plant species dominate, how large some trees grow, and how rapidly nutrients cycle through the ecosystem.

Moose are commonly encountered by BNZ research personnel during winter. Despite high rates of predation by wolves and resident hunters, the moose population in the Tanana Flats is amongst the highest (~1 moose/km2) in North America.
