Long Term monitoring of Acacia

Climate change is suspected of reducing the populations of the 3 species of Acacia trees in the Arava. Precipitation has gone down in the last few decades and Acacia mortality seems to have increased. Since 2001 the Acacia trees have been monitored every year to assess the population health. We have 20 sites from the Dead Sea to the Red Sea in which we use a standardized protocol to study their populations.
