Conservation and Challenges
Conservation Efforts in Defensores del Chaco National Park
Park management focuses on protecting its natural riches, with conservation projects aimed at mitigating human impacts.
Threatened Fauna and Flora in Defensores del Chaco
Paraguay’s fauna and flora face serious threats due to various irresponsible human activities. Indiscriminate hunting, illegal trafficking and trade of species, excessive exploitation of forests, as well as the conversion of these into extensive pastures for agriculture and livestock, are just some of the actions causing a rapid loss of the country’s natural wealth.
Additionally, soil and water pollution, alteration of watercourses through the construction of hydroelectric dams, and the introduction of exotic species are contributing to ecosystem deterioration. As a result, many animals and plants are being affected, with many species now threatened or endangered.
This unchecked development model without proper planning is one of the main causes of biodiversity decline in Paraguay. It is crucial to prioritize sustainable use of natural resources and promote development that respects ecological balance, thus ensuring a better quality of life for future generations.
