This natural forest site has a Mediterranean climate, hot in summer and cold in winter, making it unique in the Algiers biogeographical region.

[15] The Barbary stag (Cervus elaphus barbarus benetti) is a large cervid subspecies of the Red Deer found in Algerian forests.

The Barbary stag is diurnal, but often eats at night in fields and meadows as a crepuscular and nocturnal species, where it feeds as a herbivore and ruminant.

When the soil is damp, this animal turns over the earth with its strong stoppers in search of invertebrates and plant roots.

Around 3,000 waterbirds frequent this forest and its lake, which hosts an average of 47 local and migratory bird species each year.

[8] The Réghaïa forest adjoining the lake is populated by hydrophilic trees (Salix alba, Populus alba, Eucalyptus camaldulensis) and the plants that live there are the cattail Typha latifolia and the rush Juncus acutus, as well as the halophilic Plantago coronopus group.

Groups of Pancratium maritimum, Lotus creticus, Ammophila arenaria and Chamaerops humilis grow in narrow strips along the coast.

It is represented by the Oleo-lentisque composed of Olea europaea, Pistacia lentiscus, Crataegus monogyna, Rubus ulmifolius, Smilax aspera and Hedera helix.

[22] The CCR has four essential missions: hunting, ornithological monitoring, scientific research, communication and public awareness.

[23] It includes an education and awareness center, an exhibition hall for plant and animal species, and two rooms, one for practical work in the natural sciences and the other for film screenings.

The CNB collaborates with a number of international centers, as the regions traveled by banded birds can be very distant, especially during migration.
