Barking Levels and PFA lagoons
Of special interest was an area of PFA dune, supporting an important dune fauna, including two Nationally Notable Na ('Pink') species new to Essex. By 2000 the whole dune and PFA area was destroyed for housing, with tiny remnants surviving only on the eastern edge and as a small area at the Ripple Nature Reserve, with a very different character.
The foreshore of the Thames here was also a remarkable area of extensive flower rich grasslands, forming an almost unique river frontage of 'natural' Thames levels habitat with saltmarsh along the river edge. Although the associated invertebrate fauna of this area is largely unknown, a population of the internationally important mining bee Colletes halophilus was present, together with an important population the closely related C. succinctus, normally associated with heather, but here foraging on Asteraceae. This warranted DNA research into its origins and evolution, but such research is now impossible - virtually the whole habitat has been destroyed.
