1 (% of respondents answering) The most popular option in each intervention category is shaded grey, but lightened if chosen by less than half the respondents. Where two choices
were similar both are shaded.
• General awareness of NFM similar to literature definitions, with a
particular emphasis on trees.
Appetite for NFM
Implement more widely?
Third sector
Academics
Farmers
Many more NFM
schemes
Several more NFM
schemes
Same number of NFM
schemes
Who should be involved in NFM?
• Groups with practical experience are highlighted for installing NFM
Who should pay for NFM?
% of respondents answering the question
• General awareness of shared responsibility
Calculating payments
• Farmers noticeable diverge from others when it comes to payment
design
Sufficient evidence?

Not only effective at
low flows(χ=17.24, p=0.01)
Paradigm shift?
• Awareness of successful pilots
• Evidence that shared responsibility message has
broken through
• Public money for public goods & contract payments?
• Co-benefits discussed not only biodiversity, soil
retention, etc. but also social, community and
psychological
• There is a large group of enthusiasts
• But not everybody is in full agreement
• Nor on the fine details of how to enable, e.g. ELMs
