“…The majority of past epiphyllous liverwort studies have focused on taxonomy (Schuster 1959;Ellis 1971;Tixier 1980;Diamond et al 1999;Zhu & Grolle 2002;Mü ller & Pó cs 2007;Asthana & Shukla 2010). Several ecological studies have focused on factors that define the epiphyllous liverwort habitat.…”

Question Is there, at the macro‐habitat scale, a relationship between the fraction of evergreen forests and the presence probability of epiphyllous liverworts? Can these two parameters be estimated and mapped using an NDVI‐based indicator that is derived from time‐series of SPOT‐VGT imagery? Location Southern China. Methods Applying the ISODATA algorithm, we classified SPOT‐VGT NDVI time‐series imagery and produced an NDVI map at 1‐km2 resolution containing 128 NDVI classes. That map and the National Land Cover Map of China (2000) were used to prepare a scheme for field sampling. For 537 1‐km2 areas, located in 19 blocks of 100 km × 100 km, field data were collected. They represented 51 preselected NDVI classes that were assumed to contain evergreen forests. Data on the fractions of forest and evergreen forest, the fraction of evergreen forest in forest present and presence probability of epiphyllous liverworts were regressed against different NDVI class‐specific indicators by means of weighted least‐squares regression (WLSR). Results The SPOT‐VGT NDVI for March was found to best explain the variation between 1‐km2 areas in the presence probability of epiphyllous liverworts (R2 = 0.64; linear relationship; RMSE = 0.38) as the area fraction (%) of evergreen forest (R2 = 0.90; exponential relationship; RMSE = 6.1%). Epiphyllous liverworts were only found within 1‐km2 areas when the SPOT‐VGT NDVI value for March was more than 0.50 (model estimate: 0.43 ± 0.20) and the fraction of evergreen forest in 1 km2 was above 14% (model estimate: 5 ± 35%). The estimation errors (with 95% confidence interval) of these two relationships were calculated using a bootstrap resampling method with 1000 replications; they were, respectively, 0.49–0.76 and 0.85–0.94 for R2, and 0.11–0.23 and 5.2–11.9% for RMSE. Other positive relationships were found between the presence probability of epiphyllous liverworts and the fraction of evergreen forest (R2 = 0.64, linear relationship; RMSE = 0.38) and between the fraction of evergreen forest and forest within 1‐km2 areas (R2 = 0.80, linear relationship; RMSE = 29%). Conclusion We show that for southern China, the fraction of evergreen forest and the presence probability of epiphyllous liverworts can directly be inferred by making use of SPOT‐VGT NDVI imagery. The findings are fully consistent with earlier reported hotspots for epiphyllous liverworts. At the macro‐habitat scale, the presence probability of epiphyllous liverworts proved quantitatively related to the fraction of evergreen forest. This suggests causal relationships with patch size and/or rainfall patterns. We believe that the derived maps may serve as a foundation for a range of further studies.

“…At one Spaws Creek locality, epiphyllous growth was conspicuous, with colonies of C. biddlecomiae covering up to 15% of the R. maximum adaxial leaf surface area and individual colonies up to 20 mm wide. Frullania asagrayana, F. eboracensis, (Diamond et al 1999;Ellis 1971;Guerke 1973) with additional counties in the Blue Ridge (23.8%; 5/21) (Davison 1997;Schuster 1959) and…”

“…There have been relatively few reports of bryoepiphylls from north of central Florida. Physiographically, most of these have been from the southern Coastal Plain in Louisiana, Alabama, Georgia, and Florida (Diamond et al 1999;Ellis 1971;Guerke 1973;Schuster 1980) with a few localities reported from the southern Blue Ridge of North Carolina and Tennessee (Davison 1997;Schuster 1959) and the Appalachian Plateau of Tennessee (Davison 1997 ; Fig. 1).…”
