A site for botanists in Hampshire

Welcome to this site, which provides a forum for the Botanical Society of Britain and Ireland (BSBI) in Hampshire, and acts as the web site for the Hampshire Rare Plant Register project. Much of the activity detailed here is also organised by, or in collaboration with, the Hampshire Flora Group which is run and financially supported by the Hampshire and Isle of Wight Wildlife Trust.

New material becomes available here quite often, so check back in the near future. To see what's new on the site and to hear about what's going on, go to the News page.

Cerastium arvense

Field Mouse-ear Cerastium arvense is a plant mostly found on the chalklands in Hampshire, yet it is often on ant-hills or spots where some of the lime has leached out. Its attractive flowers are much larger than those of the common species of Cerastium seen in grassland and open ground. Never abundant but once widespread in much of the county, it has declined to a point where it has been seen in only eight spots in North Hampshire in the last 15 years, and only one in the south. Many roadside verges which once harboured it are now totally unsuitable, being dominated by coarse nitrogen-tolerant plants.

These plants are part of a long-established population in the Worthy Down area north of Winchester, and were spotted by local naturalist Andy Barker. His is the first record for the site since 1969, despite their forming a large flowery patch over about 400 square metres. If you would be interested in following up on other old records, contact one of the vice-county recorders for details.
