Course: Ecohydrology / Instructor: Dr. V. Iakovoglou

2 Shade intolerant species (salix, populus etc.) Initial forest
Non-vegetative area Shade intolerant species (salix, populus etc.) Initial forest Shade intolerant species Shade tolerant species Transition forest Shade intolerant+ tolerant species Shade tolerant species Fire, wind, insects, anthropogenic interference Abrupt disturbance Shade intolerant species at all levels Best growth level Old growth Death Regeneration phase Old growth CLIMAX

17 Disturbance – Climate change
Climate change alters the biological balances. Planting the right species at the right place reduces stress and increases transplant success. Course: Ecohydrology / Instructor: Dr. V. Iakovoglou
