Brown mesite is suspected that the population is rapidly declining because of predation by dogs, rats and by hunting. Its forests are also threatened by logging and subsistence agriculture. The International Union for Conservation of Nature has classified the conservation status of this bird as ″vulnerable″.

New Guinea is about the same amount as that found in the United States or Australia. A high percentage of New Guinea's species are endemic, and thousands are still unknown to science: probably well over 200,000 species of insect, between 11,000 and 20,000 plant species, and over 650 resident bird species. Most of these species are shared, at least in their origin, with the continent of Australia, which was until fairly recent geological times part of the same landmass (see Australia-New Guinea for an overview). The island is so large that it is considered 'nearly a continent' in terms of its biological
