This was a very difficult guestion to answer but we came to a very rough estimate of. 420,000 Leicestershire records of 9,000 species. This does not include approximately 750,000 records associated with specimens in the collections! Of the 420,000 records, approxinately 120,000 refer to about 4,000 species of invertebrates.
