4. Strategic objectives Recommendations for scientifically underpinned management of ponds  Conserve and enhance biodiversity at various scales (local, regional, landscape)  Conserve and enhance biodiversity at various scales (local, regional, landscape)  Sustain economic activities and ensure economic growth  Sustain economic activities and ensure economic growth

5. Study the organization of pond biodiversity –including ecosystem functioning –at multiple spatial scales –relate it with important driving variables (pond age) Quantify effects of management strategies on local and regional pond biota biodiversity Operational objectives

6. Broaden knowledge on pollutants and their effect on pond biota Obtain insights into the way stakeholders value risks and benefits of ponds Investigate how the creation and maintenance of ponds can be promoted in a sustainable way Operational objectives

7. WP1: Biodiversity at multiple spatial scales: patterns and driving variables WP2: Biodiversity and pond age WP3: Biodiversity and ecosystem functioning WP4: Assessment of management techniques WP5: Pollutants and biodiversity WP6: Social and economic relevance to stakeholders WP7: Valuation of results, policy, recommendations Work packages
