Doing Ecosystem Science
at the Right Scale
Dave Raffaelli
Director of BESS
Biodiversity & Ecosystem Service Sustainability
Ecosystem services are generated
at landscapes scales
Managing landscapes for
services means making
decisions under uncertainty
Choices mean trade-offs
 Decisions have long-term
implications.
 Avoid closing down future
options.
 Sufficient evidence base?
 No - too much uncertainty.

Sources of uncertainty


Uncertainty in processes

what is the relationship between biodiversity and ecosystem
services?

Are there critical levels of biodiversity?
Uncertainty about futures


how will biodiversity respond to climate change, land-use
change?
Uncertainty in human behaviour

how will people respond to management?

Are the answers to these questions scale-dependent?
Why scale matters
Ecological patterns and processes
occur at different scales
10,000

forests
century
invertebrates
year
months
landscape
change
leaves
El Nino events
forest fires
days
phytoplankton
hours
thunderstorms

Research at landscape scales
•Experimental and control
plots in matched pairs
•Challenging to achieve

How the BESS Programme will work

£13M NERC programme

Feb 2011 - Jan 2017

AO in Spring, grants awarded later in year, to start early
2012
 £9M in the first tranche

Awards up to £3M

Representation of early career researchers

Focus:
 Landscape science (all scales; most of Biodiversity
Theme could be accommodated)
 Systems under pressure and rapid change
 Inter-disciplinary
