FNU Seminar 15 November 2006 Land-use option conservation: Habitat requirements for wetland species in Europe Kerstin Jantke Research Unit Sustainability and Global Change University of Hamburg

FNU Seminar 15 November 2006 Outline Research topic and questions Methods and intermediate results Current work / problems Outlook

FNU Seminar 15 November 2006 Research Topic FASOM model: Economic optimization of land allocation  Habitat requirement  Habitat potential Traditional agriculture and forestry Bioenergy/ biomaterial plantations Nature reserves

FNU Seminar 15 November 2006 Research Questions How much wetland area is required for biodiversity conservation in Europe? Where should this area be located? How should it be composed? After implementation into FASOM-model: estimate the costs of wetland habitat protection explore synergies and tradeoffs between biodiversity policies and other policies that affect land use (e.g. climate or energy policies)

FNU Seminar 15 November 2006 Methods 1. Representation  Place prioritization algorithms 2. Persistence  Population Viability Assessments

FNU Seminar 15 November 2006 Vertebrate species as surrogates for biodiversity Habitats Directive (Annex II) & Birds Directive (Annex I) –16 amphibians –4 reptiles –9 mammals –43 birds Place prioritization: ResNet and Marxan Methods: Representation 72 wetland species of European conservation concern Atlas data

FNU Seminar 15 November 2006 Results: Representation Representation target 10 … …

FNU Seminar 15 November 2006 Results: Representation 10 representations of each species (n Species =72) 151 cells selected (n Cells =2016)

FNU Seminar 15 November 2006 Results: Representation

FNU Seminar 15 November 2006 Selected cells for representation target 10 Ramsar wetlands (> ha)

FNU Seminar 15 November 2006 Selected cells for representation target 10 Selected cells for representation target 10 (including Ramsar wetlands)

FNU Seminar 15 November 2006 Next step: Persistence Species GroupMVP size 1 Long-lived/large vertebrates120 Middle-long lived/medium sized vertebrates200 Short-lived/small vertebrates200 1 numbers of pairs/territories/families (adapted from Verboom et al. 2001) Habitat area min = MVP size/colonization density

FNU Seminar 15 November 2006 Next step: Persistence Habitat area min = MVP size/colonization density

FNU Seminar 15 November 2006 Next step: Persistence Species – Habitat Mapping Habitat Classification (C. Schleupner) 1. Mires 1.1 Bogs 1.2 Fens 2. Wet forests 2.1 Alluvial Forests 2.2 Swamp Forests 3. Natural Grasslands 4. Open waters 4.1 Running Waters 4.2 Standing Waters x : necessary / : optional

FNU Seminar 15 November 2006

Outlook: Linkage of Representation and Persistence Habitat area min Representation target Mires Wet forest Grassland

FNU Seminar 15 November 2006 Outlook: Integration in land-use model Cost Representation target FASOM- Model Habitat requirement for each habitat type in hectares per country
