Abstract
Biological conservation has a long story, but what distinguishes Conservation Biology from previous conservation fields is its multidisciplinary scope and its character as a mission-oriented crisis discipline. These characteristics suggested the introduction of the metaphor of biological conservation as a sort of surgery. This paper is about the initial stages of such surgery. Firstly, some data about the so-called “Big Sixth”—the disease—will be presented together with some information about Conservation Biology—the surgeon. Then epistemic and epistemological difficulties in extinction assessment and conservation prioritization, and triage in particular, will be pointed out. It will be argued that, while data deficiency arising from empirical and practical constraints can in principle be overcome, a different order of difficulties stems from the competition among several species concepts. In this case, it will be suggested that the extent of complications is of such significance to require a thorough re-assessment of the very nature of the patients, i.e., outside the metaphor, of the concept of species.

Even though biodiversity conservation cannot be reduced to species conservation only, species remain the primary target and the focus of conservation efforts.
Notice, however, that the IUCN Red List is strongly biased towards terrestrial species, and towards animals rather than plants, even though “steps are underway of rectify these biases”, as it can be read in the IUCN Red List Overview (http://www.iucnredlist.org/about/red-list-overview).

An additional source of discrepancy in counting species is the cognitive biases of researchers, such as count creep and lumper/splitter tendencies, as analyzed by Jody Hey (2001).
