How to find sample locations for species of interest for Species Distribution Models (SDM)?

By Patrick Schwager

Now the new season starts and the question is how to optimize fieldwork. During the past week I have been thinking about the sampling design for a number of new species that will be included in species distribution models (SDM). The aim is to find new occurrence sites of this species within the Styrian Alps. A variety of meaningful site properties need to be incorporated in SDMs to cover the whole range of the species’ preferences. The process for the random selection of sampling sites shall also be automated within an R script in order to avoid making the redundant steps by hand.

It is the fourth day of our upper Styria-trip and we meet our colleague Dietmar who is working for his Master’s thesis at mount Angerkogel. He will show us some remote places where we will hopefully find special species from our target lists, not least Crepis terglouensis, which Christian and I have been looking for since the start of our collaboration with the Millennium Seed Bank Partnership in 2013. The way is long, nearly 5 kilometers, as we did not choose the direct way over mount Nazogl which we can see from the car park, as the longer way promises a good yield of seed collections. …
