changing habitat opportunities for farmland wildlife
Changing habitat opportunities for farmland wildlife
  • Energy crops are structurally very different from conventional crops
  • Fewer applications of fertilisers and herbicides
  • Impacts on biodiversity will depend on type of crop, land use being converted and management of crop

Miscanthus

More open patches

More weed cover

More birds recorded

More worms

More large beetles,

Spiders and Springtails

Wheat

Dense even cover

Fewer weeds

More skylarks

More small beetles and flies

Short Rotation Coppice- potential positive impacts
  • Several studies in last 15 years mostly in pre-commercial plots
  • Sage & Robertson (1996) found similar birds in SRC to traditionally managed willow coppice
  • In Sweden several bird species benefited from the planting of SRC

DTI funded ARBRE studyWhat is the wildlife potential of commercially managed SRC
  • Compare 22 SRC fields with arable and grassland controls
  • Plot size 5 - 27 ha, in central England.
  • Four-year cycle
  • Birds, plants and butterflies surveyed in all 44 plots throughout
slide16

Good management practices will improve biodiversity value of the crop

  • Avoid sites with existing value to wildlife
  • Encourage mix of land-uses
  • Headlands and rides
  • Low inputs
slide17

What we don’t know:

  • Colonisation processes- how important is adjacent habitat
  • Bird productivity
  • Regional variations
  • Enough about the impacts of intensively grown energy grasses
