Halosere A plant community in a succession that starts on land periodically inundated by the sea. Haloseres include salt-and flooding-tolerant pioneer communities on mudflats and saltmarshes.
On the train out to meet Spencer, I had marvelled at the Pitsea horizon, a nonsensical Thames estuary hillside towering over the mudflats, a Brecon Beacon of waste.
What you see when you glance at this environment are a bunch of what appear to be tunnels or mounds here, and these are made by the gases produced by the microbes living in this mudflat area.
The mudflats here have witnessed tens of millions of years of history and experienced countless tides rising and falling, forming a unique ecological landscape.
