  2. Division of the Plant Kingdom

  3. Biodiversity according to the CBS Biobase

  4. Dutch responsibilityPercentage of theEuropean bird population

  5. Habitat responsibility

  6. The distribution of two world-wide rare species marsh fleawort (moerasandijvie) black-tailed godwit (grutto)

  7. Kinds of responsibility B Very threatened BA Very threatened, important internationally BD Very threatened, vulnerable C Threatened CA Threatened, important internationally D Vulnerable DA Vulnerable, important internationally

  8. Legend units • Global • Continental • National • Regional

  9. Gobal and continental types

  10. R=1000kmContinental areas of vegetation

  11. R=100km: National counties of flora

  12. Dunes and rivers Dispersion of marram (helm) Dispersion of greater burdock (grote klis)

  13. Haf and Pleistocene Dispersion of meadow barley (veldgerst) Dispersion of wavy hair-grass (bochtige smele)

  14. Other national typologies

  15. The condition of measure The smaller the open area the less animals could find a habitat. But that is not the case for botanical biodiversity as far as their dispersion is not dependent on big animals.

  16. Possibilities for nature (H+N+S)

  17. Possibilities for recreation (H+N+S)

  18. The EHS for the Netherlands The EHS worked out on Internet for the province of South Holland and the Gelderse poort

  19. Nature target groups

  20. Lay-out, conservancy, development

  21. Nature-target types per physical–geographical region

  22. Nature-targets higher sandy soils

  23. Elaborated targets 300 m.

  24. Higher sandy formations

  25. Northern coast formation

  26. Mid-West coast formation

  27. Boulder clay formation

  28. South Limburg

  29. Verlanding

  30. Ecologicaltolerance

  31. The ecologist’s view • Andrewartha (1961):Ecology is the scientific study of the distribution and abundance of organisms. • Krebs, C.J. (1972, 1992): Ecology is the scientific study of the the interactions that determine the distribution and abundance of organisms. • Begon; Harper; Townsend (1996): Ecology is the scientific study of the the interactions that determine thedistribution and abundanceof organisms, populations and communities.

  32. The designer’s view: state of dispersion(form)

  33. Alternatives of form: states of dispersion on one level of scale

  34. Types of ecology decreasing human centred approach

  35. A paradox of scale One species, perhaps counting 80% ‘unhealthy’ specimens, is healthy enough to oust 1000 other species on 1 new species by evolution per year. Which risk do we count?

  36. Types of ecology decreasing human centred approach

  37. Autecology:population and habitat Gadwall duck (krakeend) 04 Garland Weed Class (eendekroosklasse)

  38. States of dispersionon different levels of scale

  39. Principles of extension

  40. Built and open space

  41. Possibilities for nature (H+N+S)

  42. Possibilities for recreation (H+N+S)

  43. Types of ecology decreasing human centred approach
