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

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

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
