  • Teaching Exercise: This is a simple demonstration exercise used in short classes (one or a few days) to introduce people to the use of Vortex for conservation planning. It is intended to be used after the class has been introduced to the concepts behind Vortex. It can be shortened for a 3-hour session, or extended for more in-depth work.     

  • A paper that describes the concepts, structure, and examples of use of MetaModel Manager was published in PLOS ONE. The link provided here is to a downloadable zip file that contains the manuscript and all the project files used in the examples given in the paper.      URL:

  • Using Vortex to teach population biology in Portugal: I have been using Vortex as part of the hands-on classes of my course on Population Dynamics at the University of Lisbon, Portugal, for the past dozen years. This course is attended by about 30 graduate students every year, as part of two MSc degrees: Conservation Biology and Ecology and Management of Natural Resources. Here are my webpages, where students can find: The main page of the course: The vortex projects for students: I am sorry for these pages being all in PORTUGUESE, but my goal is to make the material available to students in Portugal, Angola, Brasil, and Argentina who are not so proficient in English, and I know this has been used by a lot of people.

  • Conservation planning for Wattled Cranes Bugeranus carunculatus in South Africa: With around 260 adult birds currently left in South Africa, a Wattled Crane PHVA for the South African population was conducted in 2001. Vortex was used to guide future in situ conservation action, and in particular was used to guide the development of a viable captive population and supplementation programme. At the workshop, the Wattled Crane Recovery Programme was borne, and had its core two primary goals, namely the creation and maintenance of an ex situ breeding flock of South Africa origin Wattled Cranes to serve as a genetic reservoir in the case of catastrophic extinction in the wild; and the supplementation of South Africa’s in situ Wattled Crane population through the release of captive-reared fledglings into existing wild populations. Targets were set for both of these aims through the use of Vortex. This included aiming for a captive population of at least 40 birds, following thereafter with the production of at least 6 captive produced chicks every three years for release as part of a supplementation programme.      URL:
