FIBDv8 20140601 invasives

Records of the presence of non-native mammal, plant and bird species for each island are extracted from the database (known as the Falkland Islands Biodiversity Database) for all islands in the Falkland Islands (with the exception of islands in freshwater bodies). Each record is entered according to date of survey for the period from 1765 to 2013. The date of each record provides information on the up-to-date presence of invasive species on the islands. However, consider the wording in the disclaimer. in the database, the Visits tab, which in the csv file corresponds to the date of each record, is essential for ensuring systematic data entry of all environmental data (birds, mammals, invasive species, plants, habitats and tussac). All records relating to these items have been entered in association with the date of survey visit, surveyor's name and affiliation. A desktop assessment, for example using Google Earth or aerial photographic images, is also considered to be a 'visit'. Disclaimer: islands with limited and variable data may have large and imprecise estimates or records. A number of islands have not been surveyed so the dataset is not complete. Consider the wide range and variability of survey methodology and coverage are limitations to the dataset, hence it should be used with caution.
