Population justification: There are an estimated >250 mature individuals and >1000 total individuals in Parc des Grandes Fougères (Jörn Theuerkauf in litt. 2016), 500 birds in Parc Provincial Rivière Bleue (J.-M. Mériot in litt. 2007, Theuerkauf in litt. 2016) and at least 491 mature individuals elsewhere.

Trend justification: Thanks to new field studies (Chartendrault and Barré 2005, 2006) and oral information, it appears that kagus are still present in most of the areas surveyed by Hunt in 1992. Chartendrault and Barré found that kagus were present on 36 of 82 surveyed massifs (44%) between 2003 and 2006, and populations seem to be stable or even increasing in the southern province, although they may be declining or stable in the North. In the Mont Do and Nakada area (Entre les monts Do et Nakada IBA), Hunt found 135 birds over 14 point counts. Chartendrault found 113 birds in the same area (different points) in 2005 over only 7 points (Chartendrault and Barré 2005, 2006). Rats and cats may affect the population, although there are currently no proven records of this. Hunting dogs are the main threat to the species, which particularly affect populations in unprotected areas outside of Riviere Bleue. However, hunting activity (particularly with dogs) is decreasing in some areas, allowing birds to recolonize (R. Gula and J. Theuerkauf in litt. 2012).
