Conservation of native plants

In-situ and Ex-Situ conservation
i
In-Situ Conservation
• The conservation of species in their natural
habitats
Ex-Situ Conservation
• Involves conservation outside the native
habitat
• E.g. seed storage and botanical gardens.

Ex situe conservation presntation at Hashemite University 2012

  1. 1. The Royal Botanic Garden of Jordan Ex-Situ Conservation of Native Plants: Climate change mitigation Prepared by: Oraib S. Nawash PhD, Plant Ecology and Vegetation Science University of Hohenheim Stuttgart, Germany
  2. 2. • • • • In this presentation: Bio-regions in Jordan - What is a native plant? Methods of preserving native plant. • Re-creation of five plant habitats in Jordan at Tell Ar-Rumman site • Water harvesting
  3. 3. What is a native plant? • "A native plant species is one that occurs naturally in a particular region, country , ecosystem, and habitat without direct or indirect human actions."
  4. 4. Bio-geographical regions of • Jordan • The Mediterranean Region • Irano-Turanian Region • Saharo-Arabian • Sudanian
  5. 5. • The Mediterranean region • Restricted to the highlands of Jordan extending from Irbid in the north to Ras EnNaqab in the south • Altitude ranges from 700-1750 m above sea level. • Rainfall ranges from 300-600 mm. • Comprises the most fertile part of Jordan and presents the best climate for the forest ecosystem.
  6. 6. • Irano-Turanian Region • Narrow strip of variable width which surrounds the entire Mediterranean region except in the north • Mainly small shrubs and bushes • Altitudes usually range from 500-700 m, • Rainfall ranges from 150 to 300 mm.
  7. 7. The Saharo-Arabian region • • Almost 80% of the of total area. • Altitude ranges from 50 to 200 mm. • Vegetation is dominated by small shrubs and small annuals located in wadi beds.
  8. 8. The Sudanian region • • - This region started at al-Karamah in the north and continues to the south through the Dead Sea depression and Wadi Araba, which end at the tip of Gulf of Aqaba. • - Altitude is the main feature, considered the lowest point on earth (-400m below sea level). In some points it reaches 120 m above sea level • - Annual rainfall ranges from 50 to 100 mm. • - Is characterized by the presence of tropical tree elements
  9. 9. Why we need to conserve native plants? •
  10. 10. Conservation of native plants In-situ and Ex-Situ conservation i
  11. 11. In-Situ Conservation • The conservation of species in their natural habitats
  12. 12. Ex-Situ Conservation • Involves conservation outside the native habitat • E.g. seed storage and botanical gardens.
  13. 13. Ex-Situ conservation of native plants at the RBG of JordanRecreation of five habitats
  14. 14. Habitat based conservation
  15. 15. Taking into consideration • Bio-geographic conditions • The complete watershed area • Soil condition • Exposure to the elements
  16. 16. Yarmouk Highlands deciduous oak
  17. 17. Dibben Pine Forest Habitat
  18. 18. Dana habitat
  19. 19. Jordan Valley Habitat
  20. 20. Fresh Water Habitat
  21. 21. • Ensuring the propagation of threatened species • Stocking the garden for landscaping purposes • Providing the public with native species nursery
  22. 22. Water Harvesting
  23. 23. climate change • Is a change in the statistical properties of the climate system when considered over long periods of time, regardless of cause.
  24. 24. What is BIODIVERSITY!??? What is it’s value!!!!
  25. 25. What are Climate Change effects on plant biodiversity According to Earth watch Institute (Europe) Climate change has already produced significant and measurable impacts on almost all ecosystems, taxa and ecological processes, including changes in species distribution, timing of biological behaviours, , ecological interactions and community dynamics.
  26. 26. FACT Species have evolved over millions of years to adapt to specific climatic conditions as well as to variations in climate, but the current increase in temperature and differing weather patterns has occurred over an extremely short period of time which evolutionary processes are not able to match. Therefore, many species of plants and animals are not able to adapt to changing temperature and weather.
  27. 27. Global climate change creates conditions that may be suitable for some invasive species to become established in new areas.
  28. 28. Shifting seasons and phenology Changes in seasons are • already being noticed in many temperate regions
  29. 29. Plants and pollinator relationships What do you expect to happen??
  30. 30. Example: Colorado Rocky Mountains, United States, Research on pollination ecology in the Colorado Rocky Mountains, United States, found that flowering time for plants is determined by the snow melt, which is likely to change in response to climate change.
  31. 31.  “The difference in timing between seasonal events at low and high altitudes has negatively influenced migratory pollinators such as hummingbirds, which hibernate at lower altitudes and latitudes. If climate change disturbs the timing of flowering and the behavior of pollinators such as butterflies and bumblebees, then the intimate relationships between plants and pollinators that have co-evolved over thousands of years will be irrevocably altered”.
  32. 32. Changing patterns of precipitation and evaporation • It is widely expected that rainfall variability and dry season severity will increase.
  33. 33. Protect our Natural Resources and Conserve our Biodiversity
