In partnership with Plantlife's 'Back from the Brink' project, English Nature has placed the tower mustard under its Species Recovery Programme. There is also a UK Biodiversity Action Plan for the plant.
Part of the Action Plan recommended a survey of all the known sites and in 1999 this was carried out. The report's aim was to establish the true status of tower mustard, evaluate the current management of the existing sites and make recommendations for future regimes, and to make an ecological assessment and fill in the gaps about our knowledge of the plant and its requirements.
Actions at some of the sites have concentrated on the removal of scrub, together with increased grazing to reduce the competition from more vigorous plant species, and create areas of disturbed ground. Seed from the plants has been stored and, when conditions at known former sites are more favourable, this seed will be distributed over the site or germinated plants re-introduced.
It is also hoped that a reserve population of tower mustard plants will be established to provide a nursery stock of plants for re-introduction programmes, and from which, by further study, our knowledge of this species can be improved.
