Aren't the Broads Brilliant !
Broads Wetland Challenges and Solutions
Andrea Kelly
Vision for managing the Broads for Biodiversity and Water
Issues and challenges to managing the Broads
Examples of some actions
Ecosystem services
•Value to the economy
•Protecting assets
Integrated approach
• Joined goals for land & water environment
• Multi-benefits
No deteriorati
on
• Evidence-based prioritising measures
• Towards targets – Biodiversity 2020, WFD
Cost effective
• Partnership efficiencies
• Budget restrictions
Why Biodiversity and Water ?
Ecological Network
Habitat & Species
Pressures
Nutrient & sediment
Water use
Physical modifications
Isolation of sites
Disturbance
Habitat & Species
Pressures
Climate change & sea level rise
Development & land use
Prymnesium & blue greens
Invasive non-native species
Global & market economics
People at the heart
Local sustainable management
Local site access
Changing communication
mechanisms
Wide investment in natural capital
Improving understanding
Lack of long-term data
Lack of knowledge beyond our boundary
Changing pressures
Lack of evidence - habitats & species

E.g. Condition of protected sites Target = 95% of SSSI
area in favourable/ unfavourable recovering by 2020
Nearly at 90% 758 ha not meeting
Target condition, over 40% is open water e.g Hickling, Horsey Mere & Hoveton Great BroadTarget

Using the survey results
Q9 Over the past 5 years, do you believe that the distribution of invasive species in the Broads has changed?
Public Opinion: How serious is the threat
What does the data tell us?
Most recognise the increase
The Unsure 24%The majority of unsure respondents owned pleasure cruisers who visited the Broads < once per month
Increaseda lot
Increaseda little
Stayed the same
Decreased a little

Unsure
55% increase in awareness
3. Improving evidence - habitats & species
Biodiversity Audit MapRare species vulnerable to saline incursion
> 11,000 species
> 1,500 of conservation concern
65 depend on the Broads
5 species lost per decade
Fen Raft Spider
More spiders in the right places
