Cantharellus garnierii is a chanterelle of New Caledonia, which appears to be able to associate with a range of host species. It may be threatened at certain sites by mining activities, but it is thought that it would not approach the thresholds for listing as threatened under any criterion. Therefore, C. garnierii is assessed as Least Concern.
Why suggested for a Global Red List Assessment?
This species of chanterelle has been recorded from a range of localities in New Caledonia, on both Grand Terre and Ile des Pins (Ducousso et al. 2004, Buyck et al. 2016). Given that the species appears to associate with a range of tree species, it is also likely to be found at further sites across Grand Terre, and could even occur across the island.
Population and Trends
While there may be some localised declines at sites where nickel mining occurs, there is not clear information regarding the population trend elsewhere in New Caledonia. As such the population trend, overall, is uncertain, but even if it is in decline then the rate of decline is likely to be fairly low.
Population Trend: Uncertain
Habitat and Ecology
This species has been recorded from forest habitats, including relict dry forest patches in New Caledonia (Ducousso et al. 2004, Buyck et al. 2016). It has been collected under Nothofagus balansae, N. codondandra and Acacia sp. (Buyck et al. 2016), while Ducousso et al. (2004) suggest additional potential host trees as Acacia spirorbis and Casuarina collina.
Nickel mining is a key threat in New Caledonia, and this species has been collected from several areas that have nickel mines (see Ducousso et al. 2004). However, given that the species appears to associate with a range of tree species, it is likely to occur at many sites that are not being impacted by mining, and so this probably presents only a minor, localised threat to the species.
Mining & quarrying
Further survey work should be conducted to see how widespread this species is in New Caledonia, and to identify how many host species it may have.
