BED 3 - CHALK CLIFF EDGE:
This is a mixture of flintstones, chalk boulders and crumb and is very exposed. Like the cliff edge, it contains no plant nutrition nor provides areas for plants to take root. Chalk crumbles and is weathered by wind and water, forming fissures. Here 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.
Examples here are: Buckshorn plantain, Sea-lavender, Sea-stock and Bloody cranesbill.
