État de la populationExpert
The population of Gastrorchis humblotii is currently thought to be decreasing since the species is collected for horticultural purposes and the habitat is threatened by forest clearing due to mining activities, and forest degradation by illegal collection for horticulture, selective logging, timber harvesting for small-scale subsistence, fire-related to Cannabis cultivation. The number of mature individuals of G. humblotii is not known and cannot be estimated as it is a terrestrial herb Growing below trees in the forest.
