BED 3 - CHALK CLIFF HABITAT:
This is a mixture of chalk boulders and crumb and very exposed. Again it contains no plant nutrition nor provides areas for plants to take root. Chalk crumbles and is weathered by wind and water forming fissures. In these fissure some deep rooted plants can form attachment and are the pioneers for this habitat. Gradually communities form along these fissures in the humus of decaying pioneer plants.
