I did not see such a thread before. How much donations raised AZA or EAZA or individual zoos for conservation of national parks, reserves etc?
According to AZA's website the total amount donated yearly to conservation efforts is over $231 million a year (this is all AZA institutions combined).
I can’t say how much, but I am aware of a couple of things the closest zoo to me (Scovill) does: A donation box for the protection of a Costa Rican Forest They raise money for cheetah conservation
According to its annual report, in 2020, the Wildlife Conservation Society (NYC Zoos) spent $123 million on its global programs, all of which I believe are conservation efforts. I'm unsure if that number directly feeds into the AZA number, but if so, that is astonishingly more than half of all money donated by AZA institutions to conservation efforts.
