Cladonia perforata is an endangered terrestrial lichen which co-occurs with many fire-adapted species in central Florida scrub. Prescribed fire is a common tool in the maintenance of natural landscapes and of high diversity within some plant communities, but its role in lichen communities is little studied. A prescribed fire at Archbold Biological Station on the southern end of the Lake Wales Ridge impacted three separate populations of C. perforata in July 1993, leaving only remnant unburned patches scattered among completely burned areas. This study was undertaken to investigate the rate and mode of post-fire recovery of C. perforata in comparison with co-occurring lichens. Detailed GPS maps of individual patches of this lichen were made in January 1997 and compared with those made in August 1999. In addition, abundance of all lichen species was monitored yearly during the winters of 1997-1999. Although all of the other terrestrial species in the same habitat recovered from juvenile stages, no juvenile forms of C. perforata were recorded. The area occupied by C. perforata increased by more than 200%, on average, over the three sites. However, population growth (for all species) has so far been too slow to be documented and has not changed markedly over this period. Therefore, dispersal of unburned C. perforata into burned areas may be the primary method of short-term population recovery.
