areas not subject to seasonal drought, and wilt of<br />
Dalbergia in some areas. Avoiding planting in risky<br />
areas can circumvent these, although in the case of<br />
pine, it is not feasible to avoid planting it in its native<br />
range in Sumatra.<br />
New plantation species<br />
The risks to the new species are presented in Table<br />
5.2. No major problem has so far been experienced in<br />
these 14 species, but there are indications of impending<br />
problems, such as root rot in Eucalyptus spp. and root
