Vegetation dynamics

We will record vegetation dynamics both by manual and digital photography surveys of 1 m2 quadrats. We will also measure growth increments of the key vegetation types (Calluna and Sphagnum). The major vegetation types observed at the sites are: heather (Calluna) dominated shrub vegetation; sedge or rush dominated stream areas or Sphagnum cover. In 2012, before mowing or burning, sites were characterised by similarly tall heather stands (~35 cm) with notably low plant diversity (~8 or 14 species per 1 x 1m and 5 x 5m plots, respectively). The dense Calluna cover (~60%) further contained mostly about 10% fractions of sedges (Eriophorum sp.), Sphagnum moss and other moss. All very typical for heather dominated grouse moor. All sites are classed as NVC M19a (based on the % plant species cover per uncut plots).
