VITAL Ecosystem ser. VIce provision from coupled plan. T and microbi. AL functional diversity in managed grasslands LECA (France), LEM (France), UCBN (France), UIBK (Austria), ULAN (UK), HELM (Germany), UB (Spain) 1
Objectives of VITAL • Core hypothesis: • Multiple ecosystem services in grasslands, and their vulnerability can be explained by the coupling among plant and soil microbial functional diversity (FD) • Core objective: • Building a conceptual model of relationships among plant and microbial FD, and multiple ecosystem services (ES) delivery 2

Expected impacts and dissemination strategy • Scientific: – Publications and conferences – International research networks – within two years of the end of the project • Stakeholders and end users (managers and policy makers): – Participatory process (WP 1&6) – Increased awareness • General public: – Web site and brochures – Toolkit for training of students and managers 7
Who are the users of the results? 8
How do you intend to involve users/stakeholders in your project? • Continuous stakeholders consultation Participation Directions of information flow – Identification of ES – Scenario development – address requirements and interests • Stakeholders information – About processes – About results 9
Long term impact/legacy of VITAL research • Basic understanding of ecological constraints and opportunities for multifunctionality in European grasslands: guide policy and management for future ES delivery. • Raise awareness of farmers, policy makers and the public about non-remarkable biodiversity and its role, especially in soils. • Enhance sustainable delivery of ES with training material (Toolkit) adapted to target groups. 10
How will your project outputs be designed in order maximize appropriate use? • Workshop strategy: present project and outputs, AND elicit feedbacks and perception of actions that need to be taken in the future for sustainable rural development. • Field demonstrations of monitoring methods for assessing functional diversity and ES delivery • Toolkit for managers of mountain grasslands and students: concept of ES, current status of biodiversity, interrelationships of fertility and ES, possible changes under plausible scenarios by 2030, and social, cultural and financial feasibility. • Design jointly options for appropriate policy measures for increasing the provision of ES, along with biodiversity conservation and maintenance of economically viable production. 11

Hypotheses: (i)Increased dominance of traits linked to conservative or exploitative plant strategies promotes K- and r-selected microbial species, respectively (Figure 1); (ii) These plant-microbial linkages will determine C and N cycling rates, and hence the associated ecosystem services. 13

Plant traits • Whole plant: veg. plant height rep. plant height clonality defences • Leaf: specific leaf area (SLA) leaf dry matter content nutrient concentrations (N, P, C) • Reproductive: seed mass flowering phenology pollination mode dispersal mode Ecosystem properties • Max. standing biomass (live and dead) • Above-ground net primary production (absolute & specific) • Decay rate of litter • Soil texture and physical characteristics • N fertility index (from non-woody canopy N) 16
