According to this Spanish language article, complaints and concerns raised by environmental organizations and voluntary groups regarding several dismissals of experienced park rangers of Bolivian national reserves motivated an opposition senator to request reports from the National Service of Protected Areas about what happened. The directors of Madidi National Park , considered the most biodiverse protected area in the world, of the Tunari Park and of the Carrasco National Park among others, were fired.
The Bolivian Association of Park Rangers and Conservation Agents (Abolac) issued a statement regarding the "irregularities and arbitrariness" committed by Mamani.
The pronouncement indicates that Mamani dismissed directors, chiefs of protection and park rangers, as well as specialized technical personnel of that entity "without respecting their seniority or administrative career," without evaluating the performance of each one, or reaching a consensus.
They also accuse him of having selected people “without the required profile" to replace the dismissed personnel.
They also asked the Minister of the Environment and Water, Juan Santos, to intervene in this situation since these important areas are left "unprotected", which could benefit "the proliferation of illegal acts and the violation of these territories.”
“Faced with the wave of criticism…José Luis Howard (was reinstated) as director of the Madidi park, without specifying what will happen in the other cases.”
