Less Favoured Areas (LFAs)
Hill and upland farming:
Utilises 42% of UK agricultural land
Carries >60% of UK breeding cattle and sheep
Upland systems:
Complex and diverse
Difficult to isolate components
Issues of scale
Multiple goals

Research for LFAs
Improved pasture
- specialist crops- legume breeding- extensification experiment
Semi-natural rough grazing (SNRG)
- Molinia-dominant grassland- heather moorland (BD1228)
Integration
- systems studies

• Management of upland sheep systems
• Genotype x pasture type interactions
• Mixed vs. sequential grazing

Experimental systems testing:
Does co-species grazing of cattle and sheep lead to improved efficiency of production?
– complementary use of areas within pasture
– increased availability of preferred species
– reduced parasite burdens
Is the complementarity of cattle and sheep grazing reduced as the ratio of sheep:cattle is increased?
– grazing becomes competitive

Can cattle temporarily graze SNRG for environmental gain without compromising productivity?
– selective grazing
– interactions with improved pasture utilisation
Is the impact of grazing by ‘traditional’ and ‘modern’ breeds different?
– body size and differences in productivity
– nutrient use efficiency
Experimental systems testing:
