Table 1. Forestry habitat classifications used in the description of initial and second sites of Scandinavian brown bears approached by humans on foot in Sweden (in alphabetical order by code).

Habitat type	Description
G—Mid-aged forest	Refers to G1/G2 in Karlsson & Westman (1991). Medium tree ³ 10 cm diameter at breast height
R—Pre-commercial thinning	Refers to R1 and R2 in Karlsson & Westman (1991).Young forest; primary, non-commercial thinning. Tree sizes range from planting stage until medium tree is >1.3 m but < 10 cm in diameter at breast height
RD—Road	Road (irrespective of size, type or condition)
S—Mature forest	Refers to S1 in Karlsson & Westman (1991). Mature forest at the age when ca 10 years remain before the final harvest, and older (in our area an S1 forest is 80–90 years and above)
SF—Swamp forest	Swamp forest—a waterlogged ground (not on peat), often with broadleaf grasses and herbs and sedges, with trees. Contrary to the bog, in a “swamp” there is in- and outflow of groundwater that adds to the productivity, and a “swamp” often has some herbs that demand high productivity.
TRB—Tree rich bog	Like a bog (very wet ground, on peat ground with low productivity and no in-or out flow of ground water, with no or very few trees) but more rich in trees.
