Résumé : |
"Thursley Common National Nature Reserve in Surrey, south-east England, suffered devastating fires covering 228 hectares on 13 July 2006 and 150 hectares on30 May 2020 which burnt roughly 68% and 45% of the heathland respectively. When searching the literature for our article on bryophyte recolonisation of heathland on Thursley Common two years after the major fire in 2006 (Duckett et al., 2008) we made a surprising discovery. Apart from general statements about the rise and fall of classic post-fire taxa like Funaria hygrometrica (Southorn, 1976, 1977), dating back to 1925 for Surrey heathlands (Benson & Blackwell, 1926),and Marchantia polymorpha(Duckett & Pressel, 2009), and a listing of Ceratodon purpureus, Leptobryum pyriforme, Pohlia nutans and Polytrichum juniperinum as other post-fire specialists on British heathlands (Coppins & Shimwell, 1971; Southorn, 1976; Hobbs & Gimingham, 1987; Burch, 2009) and Canadian boreal mixed forest (Bradbury, 2006), plus data by Clement & Touffet (1990) showing that fires lead to monogeneric dominance of Polytrichum species, we were unable to trace a single publication chronicling the long-term sequence of the successional changes or even a full listing of the taxa involved several years after a fire. Almost equally remarkable was the lack of detailed accounts of the reproductive cycles of a range of common heathland mosses, apart from Polytrichales (Longton & Schuster, 1983), and how these might be disrupted by fires. Further lacunae are temporal accounts of bryophyte successions immediately following fires leading to communities dominated by Funaria, Marchantia, Ceratodon and Polytrichum juniperinum,apart from a single study in Tasmania (Duncan & Dalton, 1982). This paper attempts to fill in these gaps." (source : auteurs) |
