logging and slash-and-burn agriculture. Due to the highly specialized requirements for its habitat, its population is very fragmented, and the species is believed to be naturally rare. Competition for its nesting sites is a result of these strict requirements and can lead to infanticide. Its estimated population is between 2,500 and 10,000 individuals, though it is believed that the population is at the lower end of the estimate. However, due to the inaccessibility of some parts of its range, it is also possible that this species is more common than believed. The population of some of these colonies is reaching the minimum levels needed for long-term viability. It also falls victim to spring traps set for mammals by hunters. However, a more serious threat to its numbers was the widespread collection of rockfowl for display in zoos in the 1950s and 1960s. There is a risk that it will be negatively affected by ecotourism due to disturbances in its daily routine if proper viewing procedures are not followed. Cameroon is the only nation with a national law protecting this species. This law prohibits killing the rockfowl, though it can be captured with a proper permit. International trading of the grey-necked rockfowl is governed under CITES Appendix I, meaning that legal trading of this species is only authorized in extraordinary circumstances. In 2006 BirdLife International drafted an international action plan to provide strategies for protecting this species. This plan focused on surveying the remaining habitat, raising awareness amongst the local populace, and limiting the continued destruction of its habitat. This rockfowl is protected in some of the areas in which it lives by national parks. Additionally, there seems to be little habitat destruction in Gabon and on Bioko as the locations in these places in which the rockfowl lives is believed to be too inaccessible for future human development. Recent surveys have also discovered new populations of the grey-necked rockfowl.
