3.3.2 Foraging intensity
According to the infrared camera monitoring and field investigation results, the Siberian roe deer browsed lightly (10%–20%) on the saplings , foraging on ports 1 3 cm from the newborn lateral branch of the current year with inconspicuous traces and small foraging ports. The forage intensity of wapiti was high (70%–100%) , and most of the branches and leaves and the foraging ports were not neat (Figure 8).
