Biocontrol has a chequered past. However, cases of negative effects on native species fell as biocontrol became more regulated.
Yet, some claim that regulation should now be reduced to allow the timely release of a broader range of biocontrol agents. #bioinvasions

Aldo Leopold promoted the conservation of intact native communities, and described biotic homogenization & invasions ("worldwide pooling of faunas and floras") as global change: views he shared with Charles Elton, whom he met at the 1931 conference on Biological Cycles at Matamek, Quebec.

Aldo Leopold - born on this day 139 yrs ago. Philosopher, scientist, visionary conservationist.

Leopold strongly advocated conserving native biodiversity. He recognized that a lack of coevolution was the reason why nonnative species can destabilize communities:

BOTD Alfred Russel Wallace, intrepid naturalist, father of biogeography, co-discoverer of the theory of evolution by natural selection. In his book Darwinism (1889), he referred to the impacts of "invading" species (like the black rat) carried by commerce & replacing native species around the world.
Alfred Russel Wallace FRS was born #OnThisDay in 1823. He independently conceived of the theory of evolution by natural selection and his work prompted Darwin to publish 'On the Origin of Species'. Wallace laid the foundations of modern biogeography.
