Weevils in the wild

The weevil (Sporophila maximiliani) is one of the most rare and endangered and currently free-living populations in the country are unknown. The last record in the wild occurred at the end of 2014, where a small population was located in the interior of the state of Mato Grosso, which has not been seen since. In the rest of the country, the boll weevil has been extinct in practically its entire area of occurrence.

THE reintroduction of butt couples began in November 2018 in Januária in the north of Minas, an area that covers the Sertão Veredas-Peruaçu Corridor. Since then, 34 bollards have been successfully reintroduced into an area of Private Reserve of Natural Heritage (RPPN) and has been monitored by the project team Reintroduction of bicudo in key areas for the conservation of the Cerrado. To better understand the steps involving the reintroduction of boll weevils, the program People's Land accompanied the release of a couple in the project area.

In addition to reintroduction, the project also has the important role of generating scientific knowledge about the speciesand, therefore, presented some of the results at the last Brazilian Ornithology Congress that was held in July this year in Vila Velha (ES). The project is supported by Critical Ecosystem Partnership Fund (CEPF Cerrado) and International Institute of Education of Brazil and is executed by Ariramba Institute of Nature Conservation with the support of several professionals from different institutions and universities in Brazil.

The Critical Ecosystem Partnership Fund is a joint initiative of the French Development Agency, Conservation International, the European Union, Global Environmental Management, the Government of Japan and the World Bank. A key goal is to ensure that civil society is involved in biodiversity conservation.
