Natural History
The Convention Relative to the Preservation of Fauna and Flora in their Natural State, also known as the London Convention of 1933, was an early agreement among colonial powers for the conservation of nature. As one of the first general conservation agreements in Africa, and the first to specifically protect a plant species, it has been called the Magna Carta of wildlife conservation and "the high point of institutionalized global nature protection before the Second World War".
