Brecknock Rare Plant Register Introduction I learnt a lot preparing the first Rare Plant Register for Brecknock, one of the main things being that there is no possibility of it being anything other than a work in progress. The work presented here is mine as are the errors and any typos. Mike Porter, the other Joint Recorder with vastly more experience than myself, has helped and guided me greatly in understanding the county flora. Changes for this edition As with the previous edition the “Scarce” (section 2) category is limited to species with 10 sites in the county or less – unless listed as under threat nationally or in Britain and Ireland. This edition reports only those species seen in the county since 2000. The year 2020 has been a surprisingly good one for finding rare species and the timespan covered by this document is 21 years. The structure of the RPR Data comes from the BSBI1 Distribution Database plus my own database for those not yet submitted to the BSBI. Many of these records were digitised by BIS2. In addition, many records now come from the various iRecord3 recording systems, in particular the LERC Wales recording app. There are also some records used in compiling this RPR that originated on the WIRED (for BIS) and SEWBReCORD (for SEWBReC4) online platforms. These are used with the organisations’ permission. All records for the vice county have been analysed and divided into several sections, the first two of which comprise the core Rare Plant Register. The other sections are primarily of use within the county for analysing the wider recording results and make it possible to find a plant that might have been expected to be in the main document. All sections are available to anyone who submits a reasonable request for access but the RPR in printed form will have only sections 1 and 2 (the rare native and archaeophyte species that are established in the wild in the UK). This edition of the VC42 Rare Plant Register make use of data available in December 2020. Maps Distribution maps of every taxon in sections 1 to 11 are available in electronic form. See the maps on the Internet at bit.ly/vc42maps. Sections As well as a site analysis for the county this RPR has used the threat designations in the following lists: Welsh Red Data List A Vascular Plant Red Data List for Wales. Rhestr o Blanhigion Fasgwlaidd Data Coch ar gyfer Cymru. Dr Trevor Dines. 2008, Plantlife Wales. GB Red Data The Vascular Plant Red Data List for Great Britain - 2005 Cheffings, C. and Farrell, L. (Editors) (including Waiting and Parking lists) Welsh Section 42 Natural Environment and Rural Communities (NERC) Act 2006. - Species of Principal Importance in Wales (section 42). National Status (Rare or Scarce) JNCC5, Nationally Scarce and Rare Species. Brecknock Vice County The Vice Counties for botanical recording purposes were established in the mid-Victorian era and hence followed county boundaries as they then were. The BSBI1 has continued to use these boundaries to the present day. Hence the area covered is larger than the Brecknock district of Powys. Some effort has been made to be clear about the modern authority applying to the data presented in this edition. 1 Botanical Society of Britain and Ireland. 2 Biodiversity Information Service for Powys & Brecon Beacons National Park. 3 iRecord is operated by the Biological Records Centre (BRC) as part of the work of the UK Centre for Ecology & Hydrology (UKCEH).
