Updated distribution and local abundance of the endangered Cuvier's gazelle (Mammalia, Bovidae) in Algeria

The Maghreb endemic Cuvier's gazelle experienced a dramatic decline during the 20th century, both in distribution and abundance. After the syntheses published in the 1990's, we update the knowledge on the distribution and abundance of this species in Algeria from two independent sources: (1) field surveys, (2) answers to a questionnaire. The comparison of data collected 25 years after the last inventories suggests a slight reduction of the range, Cuvier's gazelles retreating to the optimum habitats along the south-western part of Algeria. Populations in Tiaret and M'sila governorates, which were particularly monitored, showed different ecology and dynamics.
