RISC Botanical Non-Native Species Records
Recording Invasive Species Counts was launched in 2010 and includes on-line recording for 19 species including eight terrestrial or freshwater plants: American Skunk-Cabbage, Lysichiton americanus; Floating Pennywort, Hydrocotyle ranunculoides; Himalayan Balsam, Impatiens glandulifera; Rhododendron, Rhododendron ponticum; Tree of Heaven, Ailanthus altissima; Water Fern, Azolla filiculoides; Water Primrose, Ludwigia grandiflora. The data is predominantly provided by members of the public but records are verified from photos by designated experts. The recording form includes the option to provide abundance using the DAFOR scale.
The records were collected through the Recording Invasive Species Counts project which was launched in 2010 as a partnership between the NBN, BRC and associated recording schemes and societies. The botanical data was collated in conjunction with the BSBI. RISC was established in raise awareness of invasive non-native species and to increase distribution data for a selection of species considered to meet a number of criteria which ensured their suitability for recording by the public. Increasing the availability of distribution data is an important component of the Non-Native Species Framework Strategy for Great Britain (www.nonnativespecies.org/).
The data should be regarded as accurate because of the verification and validation mechanisms.
The data is collected by members of the public reporting their sightings through an on-line recording form (powered by Indicia). The records are casual observations. Records submitted with a photograph are verified by a designated expert and only these records are included within the dataset.
