|Data Quality, Interpretation and
Analysis of Indicator Data
Some vegetation characteristics that are of importance to understanding broad scale and fine scale vegetation patterns within these bryophyte and lichen communities are as follows. In the Windmill Islands transition occurs from bryophyte to lichen communities with reduced water availability (Smith 1990a, Wasley 2004) as bryophytes require liquid water for survival while lichens are not dependent on liquid water and are known to experience net photosynthetic depression with excess water contents. At a finer scale, within communities, bryophyte species tend to occupy distinct distributions strongly linked with water availability (Selkirk and Seppelt 1987) and reflecting their individual physiological tolerance to desiccation and submergence (Robinson et al. 2000, Wasley et al. 2006b). Lichen species distribution responds to a combination of microclimate characteristics including water availability. A further tie with water availability may be lichen morphology. Surface area to volume ratio influences the rate of water uptake/loss, and this was found to concur with the difference rates of water uptake/loss between two fruticose and one foliose lichen species (Huiskes et al. 1997).
It is expected that environmental changes to water availability will result in a shift in patterns of distribution and abundance of bryophyte species and lichen species, although the very slow growth rates of lichens (estimates of 0.01mm.yr-1, Green 1985) may render insignificant changes between surveys. Thus, the ratio of live to moribund bryophyte cover, and abundance of key bryophyte species are the most reliable components from which to assess the impacts of environmental change.
