The PHVA Workshop Process

Complex issues in endangered species conservation planning require creative solutions.

Our Population and Habitat Viability Assessment (PHVA) workshop process – used around the world since the early 1990s – has been designed with this creativity in mind. 

A typical PHVA workshop features the scientific rigor of a population viability analysis (PVA) that helps wildlife biologists and managers more clearly understand the threats that influence populations. The PVA effort is combined with innovative methods for helping people organize and evaluate information across a broad range of disciplines and perspectives.

Through this integration, workshop participants create more effective actions for species conservation that also take into account the social, cultural, and economic needs of local people. When local stakeholders help create the action plan themselves, they are much more likely to implement it.
