A note on the fire responses of species in rosemary scrubs on the southern Lake Wales Ridge

Three herbaceous species (Lechea deckertii, L. cernua, and Paronychia chartacea) appeared in postbum samples of plots in rosemary scrubs, that were rare or absent in preburn samples of the same plots and were also rare in samples of plots in unburned scrubs. Changes in cover levels with stand age su...

Zusammenfassung:	Three herbaceous species (Lechea deckertii, L. cernua, and Paronychia chartacea) appeared in postbum samples of plots in rosemary scrubs, that were rare or absent in preburn samples of the same plots and were also rare in samples of plots in unburned scrubs. Changes in cover levels with stand age suggest that these species are displaced by the increasing cover of rosemary and reindeer lichens within 9 to 12 years, their populations then being rejuvenated by periodic fires.
