Gilbert's Porth

Gilbert's potoroo was one of first species noticed as disappearing after British colonisation, and remarkable in its rediscovery at the end of the 20th century. The relict population at Two Peoples Bay, in 2014 around 40 individuals, had survived the factors that caused the mass decline of Australian mammals in a critical weight range of species smaller and larger than themselves. The earliest records of the species are found in the letters and field notes of John Gilbert, repeated by John Gould and later authors, as the only source of information on the living species. Gould published the existing name in the Nyungar language as "grul-gyte" (1841) and later "ngil-gyte" (1863), the second…
