Environmental trends of the Tidal Thames

The State of the Thames 2021 report determines the health of the Tidal Thames environment. Using 17 indicators selected by scientific and technical experts and available data, long- and short-term trends were calculated to evaluate the current state of the estuary as a healthy, thriving ecosystem that not only sustains wildlife populations, but also provides mental and physical benefits to people. Where there are insufficient data to draw conclusions, the information provided sets a baseline from which to measure progress.
