Mapping Alberta’s Ecosystem Services via Spatially Explicit Modelling Tom Habib Alberta Chapter of the Wildlife Society Conference March 22, 2015 It’s Our Nature to Know Alberta Biodiversity Monitoring Institute Ecosystem Services Benefits provided by natural systems that contribute to our health and well-being Crop Pollination What is the value of wild pollinators to canola farmers? Canola Fields • • AAFC Rotate annually Bee Abundance Canola Yield Morandin & Winston 2006 4 Forest Timber & Carbon What is the value of… • Timber harvested from forests? • Carbon stored in forests? Silviculture Cost Forest Stands • • Age Stand Type Growth/yield Curves Eligible for harvest ↑ Volume ↑ Carbon Sawmills Carbon Storage • • • Harvested Stands AAC Haul Cost Mill Cost ↓ Volume ↔ Carbon Timber Value 5 Biodiversity Model How does human land-use impact biodiversity? Landcover Human Footprint Species Response Curves 0 20 40 60 80 Biodiversity Intactness • 0 – 100% 100 % Human Footprint 0 20 40 60 80 100 % Human Footprint 0 20 40 60 80 % Human Footprint 100 6 Rangeland Forage & Carbon Model What is the value of… • Forage produced on rangelands? • Carbon stored in rangeland soils? Native Rangelands • • • • Soil Climate Plant community Grazing System Primary Production Cattle Stocking Rate Soil Carbon Forage Use (Offtake) 7 Water Purification Where are the sources & sinks for water pollution? Precipitation Nutrient Loading Nutrient Supply Maps • Nitrogen • Phosphorus • TSS Overland Flow Nutrient Deposition Nutrient Removal Maps Cumulative River Loads Sources/sinks for points along the river 8 Water Purification: Lake Management Isle Lake Fish Kill • What/where are the sources of pollutants? • What areas are filtering pollutants? • Where should future management focus? 9 10 Ecosystem Services Model Interface Ecosystem Services Maps Biodiversity Timber Production Pollination Forest Carbon TSS Supply Rangeland Production TSS Retained Rangeland Carbon 13 Understanding ES Trade-Offs South Saskatchewan Watershed Alternative land-uses: • National Park (Waterton) • Annual cropland • Native grassland Grassland Agriculture Rangeland Soil Carbon Waterton Pollination Forage Biodiversity Intactness Forest Carbon Relative Phosphorus Retention 14 Collaborators Supported By www.ecosystemservices.abmi.ca
