3 unusual facts about Pulverised fuel ash


Pulverised fuel ash

The floral succession approximates to that of a coastal dune system, without the wind-blown deposition, so salt-tolerant plants are replaced by an attractive sward of legumes and perennials before turning to birch/willow scrub woodland.

In dry conditions these solutes rise to the surface to form a hard salt crust, impeding all plant growth, though hardy grass species such as Vulpia myuros can later colonise it.

A notable feature are the Dactylorhiza orchids which often form spectacular colonies 10–20 years post dumping, only to fade away again as the woodland thickens.
