Interspersed in the acidophilous oak woods, mostly in the valleys of the inland dunes, we find a lot of smaller moors, also called heath moors. Just like the heath meres, they owe their existence to a retaining layer of clay. Their flora is akin to the raised bogs’, but the heath moors are much smaller and rarely is the peat layer stronger than 1.5 m.
Some heath moors have not been drained and seen a cutting of peat, or at least not much of it. Here, you find quaking bog, Erico-Sphagnetum and Sphagno-Rhynchosporetum systems with Eriophorum angustifolium, Rhynchospora alba, Andromeda polifolia, Vaccinium macrocarpon, Rana arvalis and Leucorrhinia pectoralis. But many a heath moor has been drained and forested with pines over the past centuries. Therefore, a restoration of a near-natural hydrological balance is one important objective of our project.
On the edge of the moor and where there is no layer of peat we find wet heath areas. On sandy soils with a regular water supply we find, for example, Carex lasiocarpa, Drosera spec., Lycopodiella inundata, Erica tetralix and Calluna vulgaris.
We find very pronounced wet heaths where a regular browsing prevents the growth of trees and shrubs. This is the case in the Diersfordter Wald deer enclosure and in the Drevenacker Dünen, where there are sheep, not deer.
