the rivers trust autumn conference: day 2 - session 2
TRANSCRIPT
Catchment Management in the lowland farmed landscape
Payments for Ecosystem Services
Pollutant type, scale and density
Delivery – past and present
Dr Laurence Couldrick - Westcountry Rivers Trust
- Wants to improve Ecosystem Services that flow from land
- Estimated cost/benefit ratio- Sold to customer & OFWAT- 65p from bill payers = £9m
Buyer - SWW Intermediary - WRT
- Ensure works do not degrade other services- Minimise admin costs
- Monitor concept
Seller - Farmer
- Has a capital asset that generates Ecosystem Services
- Improves the function of his asset (e.g. soil management)
Payments for Ecosystem Services
5370ML

6.25g of slug pellets contains 0.25g of Metaldehyde
13.5kg of pellets contains 537g of Metaldehyde and
would be applied to 2.5ha*

Pollutants - Non-natural (e.g. Pesticides)
Pollutants - Semi-natural (e.g. Nutrients)
• Nutrients occur naturally in the soil as well as coming from farmed and urban areas• Devon and Cornwall have 368,000 cows • This is equivalent to 18.4 million people worth of sewage - approximately 30% of the UK
• Soil loss impacts water treatment presses & fisheries spawning habitats• 38% of the soils in the South West are degraded• Extreme examples show single fields losing 20% of top soil during storm Desmond• Soil loss at this level (40mm in one event series) takes 800 to 1,600 years to replace
Pollutants - Natural (Sediment)
653 pollution events found….
Pollutant scale and density
• Scale - What scale are you working
• Density – Is the pollution from many sources (diffuse) or from single sources
Upper Tamar - 1,200km2
Ottery - 125km2 Caudworthy - 26km2

Over 2,000 Wildlife Sites: 34% in good condition
A fascinating species…
They can filter up to 50 litres of water
per day
They are one of the longest living
invertebrates known. They can live
for over 100 years.
But…
Freshwater pearl mussels on the
River Torridge are not thought to
have bred successfully since the
1960’s.

Distribution of culm habitat
The remaining Culm grasslands cover only 4,000ha,
fragmented across 570 sites (In 1900 there were
around 29,500ha)

The IUCN UK Peatland Programme
exists to promote peatland restoration
in the UK and advocates the multiple
benefits of peatlands through
partnerships, strong science, sound
policy and effective practice.
The Peatland Code is the voluntary
standard for peatland restoration
projects in the UK that want to be
sponsored on the basis of their carbon
benefits
Most of Exmoor’s peatlands have been affected by peat-
cutting, drainage, or past over-burning and grazing.
- Heavily modified, dry and dominated by Molinia.
