Aspen

About

Aspen is a slender tree up to 20–30 m tall with smooth greenish-gray bark, which darkens and cracks only at the base of old trunks. The leaves are nearly round, with uneven blunt teeth along the edge. The petiole is long and flattened on the sides, causing the leaves to sway and rustle even when there is hardly any wind. Hence the saying 'trembles like aspen leaves.'

Aspen blooms early, in March – April, before the leaves appear: fluffy catkins hang from the branches. Male and female catkins develop on different trees. By the end of May, small seeds with fluff mature, which the wind disperses far.

In the Carpathians, aspen grows from the foothills to the middle mountain belt — in forest edges, clearings, burnt areas, abandoned meadows, along roads. This pioneer tree is light-loving and fast-growing; it is the first to occupy open spaces and spreads through root suckers, forming entire groves. Under its canopy, beech, fir, and spruce later grow. Aspen lives for a short time, usually up to 80–100 years, and often has a rotten core.

In autumn, aspen groves are visible from afar: the leaves turn bright yellow, orange, and red.

Beavers, hares, and deer eat the bark and branches of aspen, while woodpeckers and tits nest in its hollows. The mushroom Leccinum aurantiacum grows under aspen.
