  22. 22. Major issue for conservation and acquisition of knowledge EUDORCAS RUFIFRONS ü Vulnerable species (IUCN Red list) and decreasing population ü Unclear systematic situation (studies ongoing, many subspecies?) ü Little-studied species: the Boundou CNR is a unique observation site THE RED-FRONTED GAZELLE, BOUNDOU EMBLEMATIC SPECIES
  23. 23. A STUDY OF BIG MAMMALS ADAPTED TO CONTEXT Pedestrian transects : ü adapted to difficult conditions of acces into the reserve ü Covered each year since 2014 ü Repeated 2 times a year (Dry and rainy seasons) ü Achieved by team of 4 persons (1 technician + 3 ecogards) Materials : ü 1 GPS Garmin 60 ü 1 Tablette (Samsung Galaxy Tab 3) equipped with Cybertracker Software ü 1 Camera ü 2 motos
  24. 24. A STUDY OF BIG MAMMALS ADAPTED TO CONTEXT 12 transects of 5 km each: ü 3 transects by zone ü Reachable in rainy season ü All types of habitats crossed

  36. 36. ü A knowledge basis for numerous species as the Red- fronted Gazelle ü An active participation of the ecogards ü A long-term evolutive and seasonally study ü Cost-effective method: 1 200 000 CFA a year ü Difficulties in identification of some species evidence ü Changes of observers ü High duration of setting up (24 days/year) DISCUSSION : TRANSECT BILAN
  37. 37. ü Identification of nocturnal and/or rare species ü Data concerning populations organization ü Higher space coverage Camera trap DISCUSSION : A COMPLEMENTARY METHOD
  38. 38. CONCLUSION Still a biologically rich area Conservation efforts for 10 years Significant possible impact on wild mammals and ecosystems in general Study sites for many groups or species
  39. 39. ü To complete mammals survey with other methods (camera traps network) ü To acquire materials (camera traps, rhombo, GPS…) ü To keep on study the Red-fronted Gazelle concerning different aspects (genetic and phylogenetic, alimentation, seasonal movements…) in order to enhance its conservation ü To establish new partnerships for other species studies ü To perform the ecogards training (identification, material uses…) ü To remunerate the ecogards for their regular survey missions PROSPECTS
