Resumo(s)
The European Academies' Science Advisory Council (2017) reports that the Mediterranean forest
is already being affected by climate change (IPCC, 2014) and cork oak woodlands are particularly vulnerable
to high-end climate scenarios that go above the Paris Agreement 2° C increase in temperature. Since longer,
more frequent, and more intense drought periods are expected, stress caused by the expansion of arid and
semi-arid climate will affect the species distribution. Consequently, not only established stands may be prone
to tree mortality, but also the current reforestation effort may be jeopardized by low survival rates attributed
to the use of unsuitable genetic material.
It is expected that, through genetic adaptation and/or phenotypic plasticity, cork oak populations may have
developed significant differences in fitness and the traits related to it. In this context, provenance and
progeny trials are the best resource of material to assess the variability between and within populations from
seed sources sampled in a wide range of locations (stands) covering the geographical distribution of the
species. Profiting from the multi-locality provenance and progeny trials belonging to a Network, established
in 1998, in the initiative frame of FAIR I CT 0202 for the evaluation of genetic resources of cork oak for
appropriate use in breeding and gene conservation strategies”, where 35 cork oak populations covering all
the natural distribution area are represented. The provenance trials that where set up in different countries
are entering now the age of first debarking and this should allow to have first data about the influence of
genetics on production by different site qualities. INCREDIBLE project should document this knowledge
