A short-lived perennial herb of open communities on dry, acidic, often sandy or gravelly soils. Habitats include heaths and heathy pastures, sand-pits, dunes, tracks and, especially, open woodland and forestry rides in areas of former heathland. 0-850 m (Breadalbanes, Mid Perth).
There was little indication in the 1962 Atlas that G. sylvaticum was decreasing outside Ireland, Wales and S.W. England. However, it now appears to be declining throughout its range, despite probably being one of the few native vascular plant species to benefit from the extensive afforestation programmes of the 20th century.
Eurosiberian Boreo-temperate element; also in N. America.

Gnaphalium sylvaticum L.
Status: not scarce
This calcifuge is found on moorland and forestry tracks in the north and in dry, open woods, heaths and sandy field edges elsewhere. It often grows in open patches on the edges of grazed rides in woodland. Typical associates include Agrostis capillaris, Anthoxanthum odoratum, Betula pubescens, Cerastium fontanum subsp. holosteoides, Galium saxatile, Pteridium aquilinum, Rumex acetosella and Veronica officinalis. This is essentially a lowland species, but it occurs up to 950 metres at Knockchoilum.
It is a short-lived perennial, with small flowers, which are little visited by insects and probably wind-pollinated. It reproduces by seed. Populations can vary greatly in numbers from year to year.
The results of the BSBI Monitoring Scheme suggested that this species had declined, and this is supported by the distribution map. A more detailed study is required to establish the reasons for this apparent decline. The species may be under-recorded in some areas, especially as it is often found in small populations.
This is an amphi-atlantic species, found in Europe north to northern Norway and in western and central Asia and also in eastern North America. It is recorded as an introduction in New Zealand.
