Addressing the challenges – improving our wetlands – Andrea Kelly, Broads Authority, Senior Ecologist
- 1. Aren't the Broads Brilliant ! Broads Wetland Challenges and Solutions Andrea Kelly
- 2. Vision for managing the Broads for Biodiversity and Water Issues and challenges to managing the Broads Examples of some actions
- 3. Ecosystem services • Value to the economy • Protecting assets Integrated approach • Joined goals for land & water environment • Multi-benefits No deterioration • Evidence-based prioritising measures • Towards targets – Biodiversity 2020, WFD Cost effective • Partnership efficiencies • Budget restrictions Why Biodiversity and Water ?
- 5. 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

- 9. Nutrient input Total Phosphorus source apportionment % (preliminary) SAGIS SIMCAT
- 10. Blue green algae slides
- 12. 65 named broads – 36 (55%) subject to some form of managementFrequency Size (ha)
- 19. 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 Broad Target Norfolk Broads
- 21. Invasive non-native species Norfolk Non-Native Species Initiative E.g. Killer shrimp
- 22. Migration corridors,Ponto-Caspian species Bij de Vaate, K. Jazdzewski, H.A.M. Ketelaars, S. Gollasch, and G. Van der Velde (1992) 2010 2012
- 23. Using the survey results
- 24. 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 Increased a lot Increased a little Stayed the same Decreased a little Decreased a lot Unsure 55% increase in awareness
- 25. 3. Improving evidence - habitats & species Biodiversity Audit Map Rare species vulnerable to saline incursion > 11,000 species > 1,500 of conservation concern 65 depend on the Broads 5 species lost per decade
- 26. Fen Raft Spider
- 27. More spiders in the right places Biodiversity Audit Map Rare species vulnerable to saline incursion > 11,000 species > 1,500 of conservation concern 65 depend on the Broads 5 species lost per decade

- Next 2 slides will cover why we are working together for biodiversity and water Outline the challenges Then I will go thorough a the progress in pulling together a new strategy for Biodiversity and Water in the Broads
- We are fed up of hearing about the legacy of loss and need to make a step change for the Broads It is imperative to hold the line and enhancing our biomes, the best being the fens, wet woodlands and some marshes area We need to call upon new resources from development offsets Reducing pressures is our daily bread and butter and takes up sometime too much of our time Providing accessible and new nature areas on peoples doorsteps and involving champions business Keeping our decisions well evidence is really important. Retaining our long-term data and knowing about species effects beyond our boundary is critical.

- Our water environment is in a precarious state. Despite much investment and significant improvements in water quality and nutrient pollution over the past 30 years our map is at moderate at best with some significant areas of poor and bad.
- Invasive shrimp Dikerogammarus villosus and Dikerogammarus haemobaphes travelled across Europe from their native home in the Black and Caspian sea. They are now becoming the dominant shrimp species within European rivers. Dv and Dh have both arrived in the UK and have the potential to cause serious ecological damage.
- Within the Broads, a recent survey of water users reported that 70% of people thought that the distribution of invasive species had increased over the last 5 years Data analysis - users were asked for their main activity within broads and frequency of use Pleasusre cruisers not actively engaged with environment unlike anglers
- Park movement owes itself to enhancing biodiversity and making it more resilient. National Park primary duty. Biodiversity loss well beyond planetary tolerance. This map shows the density of some of our rarest UK species that are vulnerable to saline incursion. They are in contact with the water environment and what happens to the water matters to these species. We have been loosing in the Broads at a rate of around 5 species per decade. So our first call is not to give way at all. No surrender and no fudging
