16 LAURACEAE Eusideroxylon zwageri<br />

(ID, MY, PH)<br />

It was noted that E. zwageri is almost impossible to differentiate botanically from Potoxylon melagangai, a<br />

Borneo endemic, as <strong>the</strong>y only differ in <strong>the</strong> density <strong>of</strong> <strong>the</strong> wood, <strong>and</strong> <strong>the</strong>re<strong>for</strong>e this later species should be<br />

added to <strong>the</strong> list. Known as Borneo ironwood, it was reported to be <strong>the</strong> most sought-after <strong>timber</strong> due to its<br />

durability (Julaihi, 2007).<br />

It was reported that Sabah exports both species, but that <strong>the</strong>re is no international trade in any <strong>of</strong> <strong>the</strong>m from<br />

o<strong>the</strong>r regions (Partomihardjo, Saw & Abdullah, 2007). An export ban <strong>for</strong> <strong>the</strong> species was reported to be in<br />

place in Sarawak since <strong>the</strong> 1950s (MY participants, 2007). The MY participants (2007) considered E. zwageri<br />

(<strong>and</strong> also Potoxylon melagangai) to be a priority species in Malaysia, <strong>and</strong> a series <strong>of</strong> required actions were<br />

proposed <strong>for</strong> <strong>the</strong> species (see comments under Dactylocladus stenostachys <strong>for</strong> details).<br />

Conservation measures including legal protection, policy measures, administrative <strong>management</strong><br />

prescriptions, restrictions, <strong>and</strong> ex-situ conservation were reported to be in place <strong>for</strong> <strong>the</strong> species in Indonesia.<br />

More specifically, only <strong>tree</strong>s over 60 cm in diameter may be harvested (ID participants, 2007).<br />

E. zwageri was considered to be threatened in <strong>the</strong> Philippines, <strong>and</strong> it is listed in <strong>the</strong> country’s Red List.<br />
