No. It depends on the threat that faces the species. However, I think, as many members of the committee may be aware, the most prevalent threat, shall we say, that faces most species that are in decline is loss or fragmentation of habitat. But it is not the only threat that faces a species. Disease, invasive alien species, and so on can also be a limiting factor in prevalence of species.
