| Résumé : |
"Following a major fire on 30 May 2020 at Thursley Common National Nature Reserve (NNR), we documented in detail, for the first time for any post-fire succession, the early months of bryophyte recolonisation (Pressel et al.,2021). Funaria hygrometrica and Campylopus pyriformiswere the first new arrivals (mid-July, 56 days), from spores and caducous leaves or tubers respectively, with both taxa producing abundant protonemal gemmae initially. By mid-December (202 days) C. pyriformis had formed extensive vegetative colonies, while Funaria had numerous sporophytes of different ages. Ceratodon purpureus, from spores and abundant protonemal gemmae initially, Polytrichum juniperinum and P. formosum from rhizomes, and Marchantiapolymorpha subsp. ruderalis from spores, did not appear until early September (104 days). By mid-December (202 days) Ceratodon had young spear stage sporophytes, the Polytrichum species remained vegetative, while Marchantia was highly gemmiferous with young carpocephala.The present account advances the initial observations with two further years of post-fire bryophyte recolonisation data (December 2020 until December 2022). Here we also compare Thursley NNR and Chobham Common, the site of another major lowland heathland wildfire which occurred in late August 2020. Chobham Common is 35 km north of Thursley and has comparable weather." (source : auteurs) |
