The colonisation of china clay tips with particular reference to the role of the pioneer alga Zygogonium ericetorum is considered. The alga forms a mat over china clay waste and is particularly well developed on flat and damp areas. Steep slopes are subject to sheet and gully erosion and four principal categories of slope are recognised with regard to the colonising ability of the alga The morphology of the alga appears to be affected by the availability of water and by the presence of runoff from dung depositions. The algal cover is destroyed by urine and by heavy trampling from animals. The presence of a fungal pathogen of the genus Chloridium is reported from Z. ericetorum. [ABSTRACT FROM AUTHOR] |
