Badgeworth, near Cheltenham, is a SSSI and became the first nature reserve in the county when owner Mr. Hedley presented it to the Society for the Promotion of Nature Reserves in 1933. It?was once?in the Guinness World of Records for being the smallest nature reserve in the world in 1964. It is home to the rare adder's-tongue spearwort, locally called the Badgeworth buttercup, found at only two sites in the UK. The nature reserve is small and opens its doors once a year in June, when the buttercup is in flower, which attracts botanists from all over the UK. The pond in the nature reserve is the 'pool' in the name of the lane 'Cold Pool Lane'. ? The nature reserve is also home to a number of other plants, which include lesser spearwort, common water-crowfoot, narrow leaved plantain, marsh speedwell, pink water-speedwell, fen bedstraw and marsh foxtail. Over 305 species of beetle have been recorded at this nature reserve. Common frog, great crested, smooth and palmate newt breed in the pond. ? Badgeworth?nature reserve was handed over?to the newly formed Gloucestershire Wildlife Trust in 1962 and became our first nature reserve.
