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

3 Ecosystems-Disturbances
The more complex the ecosystems the harder to return its original stage. The greater the disturbance the harder to restore. Course: Ecohydrology / Instructor: Dr. V. Iakovoglou

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
