Hampshire axiophytes

To paraphrase the BSBI's national web site, axiophytes are "worthy plants" - the 40% or so of species that arouse interest from botanists as indicators of habitat that is considered important for conservation, such as ancient woodlands, clear water and species-rich meadows. They are not the same as rare plants: species that have only ever been recorded in one or two sites in a county may have relatively low statistical significance when considering vegetation patterns as a whole.

Lists of axiophytes are one technique for determining conservation priorities. Geographical regions with many axiophytes are usually of greater importance than those with fewer; and changes in the number of axiophytes in an area over time can be used for monitoring the outcome of management practices, or a general decline.

The BSBI nationally has identified three criteria for defining an axiophyte.

  • 90% restricted to 'good' conservation habitats;
  • recorded in fewer than 25% of tetrads in the county (exceptions can be made for species in habitats that are particularly well represented and widespread in the county);
  • known from at least 3 sites in the county in recent decades.
