I m sure we ll get this worked out Eldar seems to believe that Conservation International and the Center for Applied Biodiversity Science CABS is a POV source That may or may not be but if the information is supported by reliable authors seems to be the case as the authors are all scientists in their respective fields it should be considered reliable I m not sure that particular publication is a scholarly article it s officially classified as a report and should be treated as such That said if the information checks out I see no reason not to attribute it and add it to the article The same holds true for the second link which is a reliable technical guideline
