New Vascular Plant Red Data List - more species than ever are at risk, and more to look out for!

A new Vascular Plant Red Data List for Great Britain has recently been published. The Joint Nature Conservation Committee notes that, after an examination of the whole of the British flora, many species have been included that have never appeared on any threat lists before, but nevertheless are in rapid decline. Out of 1,756 taxa, 345 (19.6%) are currently threatened. JNCC's key messages from this are:

  • Upland plants are declining due to overgrazing.
  • Arable plants have almost disappeared in large parts of the country.
  • Plants of unimproved grassland are disappearing. Many are only hanging on in small fragments such as roadsides, and these are under severe pressure.
  • As a nation, we have been very successful at looking after our rarest species, but very bad at preventing widespread species suffering severe declines.
  • Clients of Christopher Betts Environmental Biology are increasingly aware of the rules and regulations about wild flora and biodiversity and know that we always check sites carefully for the presence of notable species so that appropriate action can be taken and problems avoided.

    JNCC go on to say that the new Red List is radically different to the previous three editions of the Red Data Book for vascular plants because this is the first time that:

  • the decline of each species has been analysed (and therefore what level of threat they face), rather than simply listing those that occur in a small number of sites;
  • all species that are native or archaeophyte (plants introduced before 1500 AD) in Britain have been looked at. This means that all species have been treated equally, and there are many new additions to the list as a result;
  • hybrids are included in recognition of the essential role they play in plant evolution;
  • species in groups that are traditionally very difficult to identify (for example, there are over 230 species of dandelion in Britain) have been included in the analysis, thanks to improved knowledge of their distributions.
  • The work has been carried out by a partnership co-ordinated by JNCC, and including the Biological Records Centre (within CEH), Botanical Society for the British Isles, Countryside Council for Wales, English Nature, Natural History Museum, Plantlife, Royal Botanic Garden, Edinburgh and Scottish Natural Heritage.
