The west part of Tide Mills is signed "Newhaven Port Nature Reserve"; but this appears to be historic green-washing by the Port of Newhaven in response to proposed development; there appears to be no funding and no active conservation in this part of Tide Mills. This part of the Tide Mills is not predominantly "pure" vegetated shingle put poor quality soil (probably derived from dredging silt) on shingle. Unlike the rest of the area, which is flat, there are many hillocks probably made of dredged spoil. The area is south of the Mill Creek, the former course on the Ouse.
National Library of Scotland on-line collection of historic Ordnance Survey maps shows that in 1873 this area was salt pans (salterns) called "The Salts".

A biennial herb of open scrub and hedgebanks, waysides, railway banks and sidings, rough grassy places, waste ground and quarries. It prefers well-drained soils, especially those over a sand, gravel or chalk substrate. It produces copious quantities of long-lived seed and may become an abundant colonist. It is cultivated in gardens and frequently escapes, becoming established on refuse tips or where thrown out. Verbascum thapsus - Botanical Society of Britain & Ireland
On the vegetated shingle to the east (where the relict mill pond lies) there is also much Mullein, but here it is mostly Orange Mullein Verbascum phlomoides,
