Long-term post-fire vegetation dynamics in Pinus halepensis forests of Central Greece: A functional group approach

摘要: A hierarchical approach for plant functional classification was applied to describe long-term vegetation change in Pinus halepensis burned forests. Plant species were initially grouped according their growth form and afterwards data on modes of regeneration, persistence dispersal, together with some other specific competitive advantages explored, resulting the identification 29 different groups, 14 woody 15 herbaceous species. Three types forests identified, structure understorey. For each forest type, a post-fire chronosequence communities selected sampling. Data sampling performed at least two consecutive years community, so as reduce shortcomings synchronic increase age range chronosequence. Even though vast majority groups proved be persistent throughout development vegetation, richness abundance did not remain stable. An annual herb recorded first after fire, leguminous forming dominant group. perennial herbs, most abundant group vivid lateral growth, while subterranean resource organs included highest number Finally, far are concerned, that played important role defining mono-specific pine, resprouting sclerophyllous tall shrubs obligate seeder short (with Cistus spp., among others). negative relationship between resprouters regeneration seeders found. The advantage proposed over classical floristic or structural approaches study is discussed, applicability this studies risk assessments due fire regime alterations.
