Description :
An initial, short-term study (1982-83) of microfloral colonization on cleared plots on Quaternary reef limestones on Aldabra Atoll revealed considerable variability in colonization rates, with wetter sites and softer rocks prone to more luxuriant growths. This paper reports on further studies of colour, biomass and effects of the developing microfloral communities from almost 100 out of the c. 300 original plots which were revisited in 1998. Many sites still show limited colonization. Where a microfloral community has re-established, weathering effects are notable and consistent with those found on surrounding rock.
