Transect 25-year Trends

A series of graphs showing the 25 year Annual Index trends for all Hampshire & Isle of Wight species, except Essex Skipper for which there is currently insufficient data. The graphs show long-term Hants & Isle of Wight trends compared with national trends, and include graphs with trend lines and linear regression coefficients. For some species, individual site trends are also shown.
