Kareiva and Marvier [2]

As I outlined in lecture, Kareiva and Marvier [2] are quite critical of the ``hotspots'' approach, because it presumes that ``the exclusive goal of conservation is to protect the largest possible number of species in the smallest possible area.''

• They suggest ensuring that no major ecosytem suffer more than a 10% (or 20% or 50%) loss of diversity.

• An alternative to hotspot analysis focusing on vascular plant diversity.
  • Identify mammal and bird genera having more than one species, all of which are listed by the IUCN as critically endangered, endangered, vulnerable, or dependent on conservation.

  • Ranked countries according to the number of highly threatened genera that occur there (Figure 1.
