If there is a loss of the keystone species, it can have a drastic effect. 14 of 17 Monoculture Growing a single variety of a single crop. 15 of 17 Ex-situ Conservation Protecting a species by removing part of the population from a threatened habitat and placing it in a new location. 16 of 17 In-situ Conservation Protecting species in their natural habitat. 17 of 17
