Challenges faced when creating an evaluation method of biodiversity on an ecosystem level

Abstract

In order to create an accurate evaluation method that properly reflects the value of biodiversity on an ecosystem level, the current and past studies of such methods must be analysed. Biodiversity evaluation models published in journals from 1995 to 2005 were studied and was concluded that in order to create an accurate model, the following four elements need to be included: the first, species from different guilds that maximize the phylogenetic diversity, as surrogates of the ecosystem should be included. Secondly, assess the extinction probability of the selected species by Population Viability Analysis. Thirdly, identify the potential habitat area of selected species by Potential Habitat Analysis. Fifthly, estimate the survival probability of the selected species in the potential habitat area. © 2007 Springer Netherlands.
