Catchment scale

For the large-scale experiment, we will establish at each of the three field sites, two adjacent sub-catchment scale experimental sites:
the ‘control sub-catchment’ and the ‘treatment sub-catchment’ (see Figure in the Expt. design section;  sub-catchment size of peat area approximately 10 ha). Pre-treatment monitoring will be carried out within both sub-catchments for one growing season after which mowing of heather within the treatment sub-catchment will replace the 'business as usual' burning still to be continued in the control sub-catchment.

Burning and mowing at Nidderdale (site's gamekeeper; gamekeeper)                                      Compaction by vehicle tracks (about 15 cm)

Burning and mowing at Mossdale (site's gamekeeper; Dalefootcompost)                                 Fine mossy heather brash (cutting height 14 cm)
Burning and mowing at Whitendale (site's gamekeeper; Dinsdales Moorland Services)             Coarse heather brash (~2-5 cm lentgh)
