Occurence data
Completion requirements
In this first module we will see where to find occurrence data (if you don’t have your own), how to download them. Furthermore we will focus of cleaning and validation procedures in order to have a suitable dataset to be use in module 2.
Visual check and filtering of data with IUCN EOOs Step 4/4
> dim(krameri)
Now we have a dataset including only records from the native range of the species (n=640).
We save this file ready for module 2:
> write.table(krameri,file="krameri_NativeRange.txt")
In module 2 we will see how to further refine our dataset taking into account the spatial resolution of the environmental layers
