Transcript

  • 1. Ecosystem Services : An example using pollination Dara Stanley PhD Researcher, Simbiosys Project School of Natural Sciences Trinity College Dublin [email_address] www.simbiosys.ie
  • 2. Biodiversity
    • = all life on earth
    Biological diversity the variability among living organisms from all sources, incl. terrestrial , marine , and other aquatic ecosystems & the ecological complexes of which they are part Bio diversity
  • 3. Biodiversity & ecosystem services Biodiversity Within species (genetic) Among species Among habitats Ecosystem functions Human well-being Source: Millenium Ecosystem Assessment 2005
    • SUPPORTING SERVICES
    • Primary production
    • Provision of habitat
    • Nutrient & water cycling
    • Soil formation & retention
    • Production of atmospheric O 2
    • REGULATING SERVICES
    • Invasion resistance
    • Herbivory, pollination
    • Seed dispersal
    • Climate regulation
    • Pest & disease regulation
    • Natural hazard protection
    • Erosion regulation
    • Water purification
    Ecosystem services PROVISIONING Food, fuel, fibre Genetic resources Biochemicals Fresh water CULTURAL Spiritual & religious values Knowledge systems Education and inspiration Recreation & aesthetic value Sense of peace

  • 9. Value of Ecosystem services
    • 17 ecosystem services in 16 biomes – Constanza et al. 1997
    Valued at U$33 trillion per year Global GNP is about U$18 trillion
  • 10. Pollination
  • 11.
    • 85% flowering plants
    • 1 in 3 bites of food
    • 39 of 57 leading crops
    • Crops: Fruit, nut, vegetable, forage, Oils
    • e.g. coffee, orange, mango, clover, bean, tea, olive, raspberry
    • Improves - quality, quantity
    • - seed production and viability
    • - genetic diversity
    Why is pollination important?
  • 12. Value of Pollination in Ireland € 53 million pa € 220-500 million pa Bullock et al., (2008) Bullock et al. 2008
  • 13.
    • 101 bee species
    • 20% social
    • 20 Bumblebee species
    • 1 honeybee
    • - Regionally extinct (RE) 3
    • - Critically Endangered (CR) 6
    • - Endangered (EN) 10
    • - Vulnerable (VU) 14
    • - Near threatened (NT) 12
    • 180 Hoverflies
    • 20 Butterfly species,
    • 1350 moths
    • Other flies, beetles
    Pollinators in Ireland
  • 14. Sunday Times, Feb. 2009
  • 15. Pollinator decline Butterflies – 9% Threatened Bees – 40% Threatened
  • 16. Pollinator decline Reduced crop production Reduced seed set in wild plants Changes in natural plant communities Impacts on herbivores and seed predators Impacts on top predators and carnivores Changes in decomposer communities, soil structure/fertility, water & nutrient cycles, erosion etc Changes in climate, atmosphere, biogeochemical cycles etc
  • 17. Threats to pollination
    • Major threats include:
        • - habitat fragmentation
    • - changes in land use
    • - agriculture and grazing
    • - effects of herbicide and pesticide
    • - introduction of non-native species
    1:5000 1:5000
  • 18. The future
    • Awareness: public and political
    • The Economics of Ecosystems
    • and Biodiversity (TEEB)
      • - Global Economic benefits of biodiversity
      • Cost of biodiversity loss and ecosystem degradation
      • Expertees – practical actions
    • Understanding
    www.teeb.org
  • 19. Simbiosys
    • Investigating sectoral impacts on biodiversity and associated ecosystem services in Ireland
    3 key sectors Impacts on biodiversity and ecosystem services www.simbiosys.ie Aquaculture Road landscaping Energy Crops Invasion Resistence Carbon Sequestration Pollination Biocontrol
  • 20.
    • Ecosystem services – crucial to human wellbeing
    • Ecosystem services can be a way forward for conservation – re-emphasizes the links between nature and well-being
