Population justification: In 1994, the population was estimated to comprise 7,920 pairs in 381 km² on Basse-Terre, and 2,410 pairs in 135 km² on Grande-Terre (Villard and Rousteau 1998). Surveys in 2007 revealed no significant change, but a different methodology calculated a total population of 8,469 pairs (Villard et al. 2010). The population is therefore estimated to number at least 16,000 mature individuals, roughly equivalent to 24,000 individuals in total. The majority of the population occurs on the island of Basse-Terre in western Guadeloupe, while a smaller percentage inhabits the island of Grande-Terre (Winkler et al. 2018).

Trend justification: Between 1994 and 2007, the global population of Guadeloupe Woodpecker has been overall stable or increasing slowly (Villard et al. 2010). Kilometric index surveys found that the population on the island of Basse-Terre has been increasing considerably between 2011 and 2015, while the population on the island of Grande-Terre seemed to be declining (G. van Laere in litt. 2016). Considering that about 75% of the population occurs on Basse-Terre (Villard and Rosteau 1998, Winkler et al. 2018), the increase there potentially outweighs the decline on Grande-Terre, and the population is overall considered to be increasing (van Laere 2015). The rate of forest loss within the Guadeloupe Woodpecker’s range between 2000 and 2012 has been negligible (1.4% over three generations; Tracewski et al. 2016). Hurricane Maria, which hit the Caribbean in 2017, did not severely impact on the forest cover on Guadeloupe (Global Forest Watch 2018).
