Note
The geographical distribution of the genus Acacia Mill. (Fabales Mimosaceae) in Algeria was
determined after the prospect, localization and description of the various species populations
overall Algerian territory. Twenty-four regions were prospected, based on relative species
abundance. Among the ten-species found in Algeria, only A. karroo and A. saligna can be
found in the whole country. However, there are some concentrations in certain northern
regions. Acacia decurrens was only found in the Northeast, with high concentrations at the
National Park of El Kala. Five of them are recorded in the southwest (A. albida, A. ehrenbergiana,
A. nilotica, A. seyal and A. tortilis). Acacia farnesiana is indicated in the Northeast
and the Northwest. Acacia laeta individuals were very rare. According to the climatic data
during the years 2000-2016, the following species adapted to the annual pluviometry, that is
lower than 100 mm: A. albida, A. ehrenbergiana, A. laeta, A. nilotica, A. seyal and A. tortilis.
Three species (A. karroo, A. farnesiana and A. saligna) are in zones with an annual pluviometry
between 250 and 500 mm). Acacia decurrens is located in a zone in which the annual
precipitation exceeds 1000 mm. This study shows the distribution of the Acacia species in
Algeria.
