De<strong>da</strong>leira em flor.<br />
Flowering foxglove.<br />
N<strong>as</strong> cop<strong>as</strong> d<strong>as</strong> árvores, <strong>as</strong> sementes do<br />
eucalipto, bem protegid<strong>as</strong> <strong>de</strong>ntro d<strong>as</strong> cápsul<strong>as</strong>,<br />
são inacessíveis à maior parte d<strong>as</strong> aves que <strong>as</strong><br />
procuram apen<strong>as</strong> para pousar. M<strong>as</strong> os troncos<br />
são muito procurados por pica-paus, em busca<br />
dos insectos que se alojam entre a c<strong>as</strong>ca<br />
e o tronco <strong>da</strong> árvore. Ironicamente, a presença<br />
do pica-pau traz más notíci<strong>as</strong> para a indústria.<br />
Afinal apen<strong>as</strong> <strong>as</strong> árvores atacad<strong>as</strong> por prag<strong>as</strong><br />
lhe po<strong>de</strong>m fornecer alimento.<br />
A todo o conjunto <strong>de</strong> animais que acabam por<br />
integrar <strong>as</strong> mat<strong>as</strong> <strong>de</strong> eucaliptos no seu habitat,<br />
juntam-se ain<strong>da</strong> numerosos insectos e to<strong>da</strong><br />
a fauna microbiana do solo que permite que<br />
a terra permaneça fértil e <strong>as</strong> árvores cresçam<br />
saudáveis até ao próximo corte.<br />
A biodiversi<strong>da</strong><strong>de</strong> patente na <strong>Quinta</strong> <strong>de</strong> <strong>São</strong><br />
<strong>Francisco</strong> é o reflexo <strong>da</strong> atitu<strong>de</strong> e <strong>da</strong> prática<br />
do grupo Portucel Soporcel em matéria <strong>de</strong><br />
<strong>de</strong>fesa <strong>da</strong> biodiversi<strong>da</strong><strong>de</strong> e <strong>de</strong> conservação dos<br />
valores naturais do seu património florestal<br />
enquanto parte integrante <strong>da</strong> política <strong>de</strong><br />
sustentabili<strong>da</strong><strong>de</strong> do Grupo.<br />
In the trees’ crowns, the eucalyptus seeds, well<br />
protected within their capsules, are inaccessible<br />
to most of the birds which only look for trees on<br />
which to perch. However, the trunks are very<br />
much wanted by woodpeckers looking for the<br />
insects that lodge themselves between the tree’s<br />
bark and trunk. Ironically, the woodpecker’s<br />
presence is bad news for the industry. After all,<br />
only pest rid<strong>de</strong>n trees supply this bird species<br />
with food.<br />
Joining the animal community in the eucalyptus<br />
forests are numerous insects and an entire<br />
microbial fauna that lives in the soil and enables<br />
it to remain fertile for the trees to grow healthily<br />
until their next cut.<br />
The existing biodiversity at <strong>Quinta</strong> <strong>de</strong> <strong>São</strong><br />
<strong>Francisco</strong> reflects the attitu<strong>de</strong> and practices of<br />
the Portucel Soporcel group, which is committed<br />
to protecting and preserving the biodiversity and<br />
the natural values of its forestry heritage in line<br />
with the Group’s principles of sustainable<br />

<strong>Aves</strong> como o pisco-<strong>de</strong>-peito-ruivo<br />
procuram abrigo nos ramos do eucaliptal.<br />
Birds, like the robin, look for shelter in the eucalyptus branches.
