The Botanical Society of the British Isles (BSBI) is for everyone who is interested in the flora of Britain and Ireland. It is the largest and most active organisation devoted to the study of botany in the British Isles.

The first ever checklist of vascular plants of the Cairngorms National Park has been compiled based on an analysis of 281,000 botanical records collected and compiled by the BSBI. The Checklist : The Flora of the Cairngorms National Park - An Annotated Checklist by Andy Amphlett is intended to be of interest and use to local and visiting naturalists, landowners and managers, professional agencies and visitors. Hopefully it will also be a stimulus to further recording. The Checklist is made freely available as a download from http://www.bsbi.org.uk/site_floras.html

The Checklist is available in summary pdf format, and as an Excel file. The latter provides the greatest flexibility for assessing the flora of any individual site against the CNP as a whole. This provides a powerful analytic tool to assess conservation significance, and will hopefully inform development decisions.

Heath cudweed Gnaphalium sylvaticum one of the scarce
plants BSCG has found at at a threatened site in Carrbridge.

The Checklist lists 1699 unique taxa, plus 34 aggregate taxa. 67.8% of taxa are native to the CNP, 6.4% archaeophyte (ancient introductions to GB) and 25.8% neophyte (recently introduced aliens). 123 taxa are endemic to Great Britain, of which 19 are endemic to the CNP and a further 57 endemic to Scotland. 1428 taxa (82.4%) have been recorded over the last 25 years, 1987 – 2011, while 106 taxa (6.1%) have not been seen since before 1970.

The table below summarises those native and archaeophyte taxa:

• Of international or national conservation concern.
• Rare in the CNP.
• Not recorded for >25 years in the CNP.
• Whose hectad (10km grid square) frequency in the CNP indicates that the CNP population is of moderate, high or very high significance within Great Britain.

The next phase of this project will be to compile a Cairngorms National Park Rare Plant Register. This will list the most recent record at each known site, for all c.758 taxa which are of national conservation concern or that are rare in the CNP.

BSBI especially through its system of vice-county recorders provided the bulk of the data. In the acknowledgements to his Check list the author lists the support provided by BSBI and Scottish Natural Heritage in undertaking the project. He further thanks NESBReC, NTS, RSPB, FES, and individual recorders for additional records and Tim Rich, Bert Reid and Mark Hill for support. Andy Amphlett and those who have helped him produce this important checklist are to be congratulated.
