In 1986-1987, a number of ecologists were involved in a dispute over design of wildlife reserves and species losses resulting from deforestation. The battle was played out largely in the pages of the Ecological Society of America Bulletin. The most focused aspect of the controversy began in August 1986 when P. C. Kangas gave a paper at the meetings of the Fourth International Congress of Ecology, held in Syracuse, New York.
Using data on trees in Costa Rica and the “objective approach” of species-area curves, Kangas argued that extinction rates due to deforestation in the tropics are actually much lower than most other researchers have alleged (Kangas 1986, p. 194). Ecologists in the audience disagreed with Kangas’ claim that extinction rates were indeed lower, complained that his questionable results would be used to justify more rapid and widespread deforestation, and claimed to have “sharply trounced his [Kangas’] arguments” (Noss 1986, pp. 278-279).
