Abstract
Characteristics of shrubs were compared inside and outside of 3 wildlife exclosures constructed between 1981 and 1985 in northern Idaho, USA. Eighteen shrub species were identified, 16 of which occurred inside the exclosures and 14 outside. Rocky mountain maple (Acer glabrum), thinleaf alder (Alnus incana), bittercherry (Prunus emarginata) and sticky currant (Ribes viscosissimum) were only observed inside exclosures, whereas Oregon grape (Berberis repens [Mahonia repens]) and red-osier dogwood (Cornus stolonifera) were the only ones found outside the exclosures. Stems per m2 were greater inside the exclosures than outside for most species. Twigs per m2, twig length, twig biomass, and average height of species were greater inside exclosures for all but two species. Overall biomass production was >=26.55 g/m2 inside exclosures compared to <=16.67 g/m2 outside. These marked differences in woody vegetation were attributed to ungulate herbivory outside the exclosures.
