Resumo(s)
Fifty-six species and
subspecies are presently recognised as indigeneous in Portugal. About half of them are rare or very rare, or even
probably extinct for two of them. The causes of rarity and the factors responsible for the regression that still
affects many species are analysed. Besides the fact that a few species have only little Mediterranean or Atlantic
affinities, there are causes linked with habitat disappearance, mainly in humid and coastal zones. Regulations
applicable in Portugal are reviewed, but few of them are specifically concerned with orchids. Furthermore
orchids are never considered among priority options towards the establishment of nature reserves and parcs. We
propose a list of sites and habitats especially rich or favourable to the conservation of orchids, which should
receive a better attention on behalf of Portuguese officers responsible for nature protection. Moreover,
knowledge of demographic and genetic characteristics of orchid populations should absolutely be developed if
we wish to guarantee the effectiveness of conservation strategies.
