Colônia 31 de Março Biological Reserve

Colônia 31 de Março Biological Reserve was a biological reserve in Brazil.

History
The biological reserve was created by Law 16.580 of 23 September 1974 with an area of 5030 ha in the municipality of Felixlândia, Minas Gerais. An audit in 2012 stated that a number of biological reserves created in 1974 on state-owned land were being re-assessed, since they no longer qualified as conservation units. These were Carmo da Mata, Colônia 31 de Março and others. As of 2016 the reserve did not appear on the list of biological reserves in the state.
