The Lund Botanical Society 2007-03-23 decided to launch a project with the following aims: 1) to map the frequency and distribution of all bryophytes in the province of Skåne, southernmost Sweden, thereby making way for future studies of changes in the flora, 2) to find and document as many sites as possible for nationally and regionally rare or endangered bryophytes and initiate conservation actions at these sites, 3) to increase our knowledge of the ecological demands of individual taxa, and 4) to enhance the level of knowledge concerning bryophytes among both amateur botanists and professional nature conservationists. The province has been divided into 534 5 x 5 km grid-squares. The central square kilometre within each grid-square will be surveyed and the result used for unbiased estimates of the frequency of each taxon. In addition, within each grid-square, a variable number of special areas which may be presumed to have a rich or unusual bryophyte flora have been preselected for the survey. Additional areas may be selected by the recorders themselves, but the ultimate goal is not to survey the grid-square as a whole. A special determination key and nomenclatural check-list to all 658 taxa hithereto known from the province, as well as various instructions and forms for the volonteer recorders, have been made available on the Internet and a central database with an Internet interface is under way. Various kinds of courses have been initiated with the aim of educating future recorders. The aim is to survey all grid-squares during a 20 year period and the project is now calling for support from bryologists world-wide.
