Population Viability

Population viability analyses play a major role in biodiversity conservation. To support conservation management, we compiled a database of minimum area requirements for species, developed a range of models and finally developed a “best-practice” protocol for the application of population viability analyses.

One of the main targets of conservation efforts is to maintain the viability of populations and species. To do so, one can run simulation analyses to evaluate whether populations are stable over time. This approach is known as population viability analysis. A range of tools are available for assessing population viability, the minimum area requirements of species, and the potential distribution ranges of species in a longer-term horizon, e.g. under land-use changes or climate changes.

Populations have complex dynamics and they may go extinct for many kinds of reasons. According to the temporal and spatial scales of interest, different kinds of models may be better at analysing population viability. The models listed below broadly follow an increasing level of complexity, moving from those that consider only random processes in a uniform system to those that explicitly simulate demographic and environmental variability.

In the project SCALES, we developed and utilised a range of tools addressing the viability of populations. These include:
