Biomass potential for individual species

Nothofagus dombeyi and Nothofagus betuloides (Coihue)

Species potential for biomass > Species potential for Nothofagus

These evergreen southern beeches are very closely related and are native to southern Chile and the Andes of southern Argentina.

They are rare in the British Isles, but their growth as specimens in arboreta and in experimental plots suggests that they are capable of very fast growth, particularly in areas of high rainfall. They also appear to be at least as cold tolerant as the hardiest eucalypts, and to recover well from cold damage, though these aspects need further testing. Techniques for establishment of these species have not been studied; limited evidence so far indicates that it is important to avoid checking the growth of young plants, as it can take many weeks for growth to resume. This suggests that moist sites in Ireland and western Britain may be better-suited for these species.

Seed supplies of these species have always been very limited and erratic, and this appears to be the case in the UK and Ireland as well as in their native habitat. However, the species can be propagated by rooted cuttings, and this offers an opportunity to evaluate them for SRF.
