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.
