Biodiversity occurrence data can be obtained through a variety of sources. They typically come as either a range maps or as GPS points. 

For Open-access biodiversity data, GPS points can be readily downloaded from the Global Biodiversity Information Facility (GBIF). This resource pulls data from published research, museum collections, and community science applications such as inaturalist.

A tutorial on accessing GBIF data can be found in this webinar recap - https://learnadv.com/webinar/webinar-how-to-access-data-from-gbif/

Expert Curated Range maps

Range maps can be obtained directly from the IUCN for some taxa. You will need to create an account and submit a request. Requests are usually handled quickly. https://www.iucnredlist.org/

Some range maps for particularly sensitive taxa may only be available upon request. If you want IUCN data, contact the working group for your taxa directly.

See a particular occurrence dataset you want to use? Double-check the methods for where they got it, or reach out directly. There's also a chance they've already uploaded their data to GBIF.

Obscuring records means hiding the true location of GPS points to prevent poaching or ecological damage from visitation. 

Here is a video guide on doing so for both social media and research - https://learnadv.com/webinar/obscuring-geotags/
