Abstract

Conclusion 1: – the isolated old woods in Richmond park are acting as remote islands for corticolous Collembola, to some extent isolated from biotic changes around them. They certainly shelter a relic population of Entomobrya corticolis (the most important site in the UK), as well as apparently relic Entomobrya nivalis.
Conclusion 2: – The isolated old woods in Richmond park show statistically significant edge effects both in microclimate and in their corticolous Collembola. The woodland centres are less windy and generally support the highest densities of corticolous Collembola. This is the first time a statistically significant edge effect has been shown in woodland Collembola.
Conclusion 3: – The peak season for corticolous Collembola is mid winter, correlating with humidity.
Conclusion 4: – The highest densities of corticolous Collembola are on trees with deeply fissured bark.
