There was only limited systematic recording in Hampshire between 1960 and 2000. However, mainly as a result of site surveys, many new records were made during that period. The main contributors of records were F. Rose, R.C. Stern and N.A. Sanderson, mostly from about the mid-1970s. Recorders include Alison Bolton who provided some very useful records of certain Sphagna, liverworts and the two hornworts, Anthoceros punctatus and Phaeoceros laevis.
