Many are also decorative garden trees, notably Korean fir and Fraser's fir, which produce brightly coloured cones even when very young, still only 1–2 m (3 ft 3 in – 6 ft 7 in) tall. Many fir species are grown in botanic gardens and other specialist tree collections in Europe and North America.
The red vole nests almost exclusively in the foliage of the trees, typically 2–50 metres (5–165 ft) above the ground, and its diet consists chiefly of Douglas-fir needles. [13] Douglas-fir needles are generally poor browse for ungulates, although in the winter when other food sources are lacking it can become important, and black-tailed ...

The leaves ("needles") are flattened, 2–4 cm (3 ⁄ 4 – 1 + 1 ⁄ 2 in) long and 1.5–2.5 mm (1 ⁄ 16 – 3 ⁄ 32 in) thick, spread at right angles from the shoot, and end in a point.
