I recently got a bee in my bonnet about how to further inspect the listing and de-listing of Endangered Species through time. The Endangered Species act was passed through congress and signed by President Nixon in 1973. It turns out that it is actually quite challenging to locate a singular list of species that have been listed in the past but have been removed from the Endangered Species protections. However, I was able to located a source of data from Ballotpedia, here. This provided me with the raw data to start making a few fun plots. Since its inception, 44 species have been listed and then de-listed from the Endangered Species act because of either 1) extinction or 2) because the species recovered sufficiently for delisting. 10 Species have gone extinct, while 34 have successfully recovered. Here Species are listed by their initial listing date.

AuthorI started learning how to program in High School. For a while now, I've been learning how to effectively use Matlab and R for data analysis and visualization. I will put the codes I've benchmarked and just interesting plots I make here. Archives
