Rock sea-lavenders (endemic)  (Limonium spp)

Many populations of rock sea-lavender in the UK are not under any immediate threat. However, some may be vulnerable to trampling (4), while several dune-slack, sea-wall and cliff populations are known to have been lost, at least temporarily, as a result of dune movements, the construction of new sea defences and coastal landslips (7). Many colonies are small (which increases their vulnerability), and collecting is thought to have posed a threat to a few species (particularly L. recurvum) in the past (4).

Many populations occur within Sites of Special Scientific Interest (SSSIs), and two populations of L. parvum occur within National Nature Reserves (NNRs) (2). Together, the Botanical Society of the British Isles (BSBI) and the National Trust coordinate the conservation actions outlined in the UK Biodiversity Action Plan for Britain's endemic rock sea-lavenders (2). The BSBI have carried out an extensive mapping scheme, which will be of enormous help as it will allow areas needing further research to be prioritised and will also aid in the initiation of a monitoring programme (2).
