Red hemp-nettle  (Galeopsis angustifolia)

Most of the factors affecting this species involve changes in agricultural practices, including the use of chemical herbicides and fertilisers, sowing crops in autumn before red-hemp nettle has a chance to set seed, and the introduction of crops that have very high productivity (1). Some shingle sites are threatened by coastal development (6).

This species is one of 15 arable plants listed on the UK Biodiversity Action Plan priority list (2). The Species Action Plan aims to enhance the current range by restoring populations to eight former sites by 2003, and set up ex-situ facilities, which will provide a source for potential reintroductions and preserve the genetic variation of this species (1).
