  1. Examples for Discussion

  2. Example 1 • Problem with forest regeneration in one fire-affected location in California

  3. Example 2 • Problem with agricultural productivity and effects on neighboring forests related to their solution response.

  4. Mexico • Soils are very alkaline • Crops have low productivity • Total analysis of soils do not show deficiency but leaf analysis show P deficiency – why??? • Available P shows deficiency • Farmers are very poor in this Oaxaca region of Mexico • How can they increase crop productivity?

  5. Example 3 • Problem with erosion in Iceland due to over-harvesting of birch and also grazing by sheep and one of their solutions.

  6. Before Viking Settlement  75% vegetated, 25% mountain birch Today  less than 25% vegetated, 1% mountain birch

  7. Erosion fronts  125,000 km

  8. Siberian Larch Lupine

  9. SITE 1 Protected for 100 years Eastern Iceland
