Temple Island Meadows is a 14.1-hectare (35-acre) biological Site of Special Scientific Interest on the Buckinghamshire bank of the River Thames.

[1][2] The site is composed of several wet meadows, which are grazed by sheep.

Plants include the nationally rare summer snowflake and marsh and early marsh orchids, which are found in locations with a long history of undisturbed grassland management.

There are invertebrates such as the endangered marsh fly Dicheptophora findlandica and the rare dragonfly Gomphus vulgatissimus.

There are also areas of wet woodland, and the diverse habitats attract a variety of breeding birds.
