MAIN OBJECTIVESComparison of current and expected distribution of 16 tree species of Central ItalyEcological scenarios expected for 2080, on the basis of to IPCC 2001 climate worst scenarios (B1 & A1F1)
Identify shelter areas (biorefugia) for main tree species in Central ItalyEvaluate value of Lev. II plots as potential shelter areas
WORK OUTLINE
1.Climate and bio-climate mapping2.Characterization of ecological niche of
each species (16)3.Maps of (potential) current
distribution of each species4.Maps of potential future distribution
(scenarios) of each species5.Identification and mapping of
potential shelter areas (biorefugia)

EXPECTED EFFECTS OF CLIMATE CHANGES ON FOREST ECOSYSTEM
Progressive desegregation of forest ecosystem: only a few components will be able to migrate in more suitable areas, whereas most of them will going to be extint, at least at local level.A desegregation process is just in the course in the most sensitive forests to climate change (e.g., floodplain forests, strictly linked to regular availability of water in the upper part of soil)
RECORDED EFFECTS OF CLIMATE CHANGES ON FOREST ECOSYSTEM
(1)
Early phenology (3 days every 10 years) in all main tree species (leaves unfolding flowers, fruits).
ALL NATURAL CYCLES ARE 15 DAYS EARLY THAN 50 YEARS AGO
RECORDED EFFECTS OF CLIMATE CHANGE ON FOREST ECOSYSTEM
