The Serra Ricardo Franco State Park was created by decree 1.796 of 4 November 1997, covering lands in the municipality of Vila Bela da Santíssima Trindade with an area of . The objective was to protect water resources and the viability of movement of native fauna, preserve samples of existing ecosystems and allow controlled use by the public. There were already squatters in the park when it was created. An effort was made to reduce the size of the park in 2003 to exclude land used for productive activities. That year the state government allowed the deadline for expropriations to expire. In November 2004 the State Environment Foundation (FEMA) presented a proposal approved by the state governor
Blairo Maggi to reduce the size of the park by . The reason was that the government no longer had money for expropriations. The areas would be those that had been occupied before the park was created, reaching to the foot of the mountains. In compensation, FEMA proposed to define an
environmental protection area of in part of the area removed from the park. The mayor of the municipality said the proposal was very interesting. He was in favor of the park as long as it was not in the productive areas. He was not concerned about loss of ecological funding, which was small in comparison to the revenue from the new areas that could be planted with soybeans. On 17 October 2014 landowners and squatters were called upon to submit documents relevant to properties in the park pending land ownership regularization. The consultative council was created by ordinance 585 of 5 December 2014. On 10 December 2015 land in the park was donated to the State of Mato Grosso in compensation for the environmental impact of the 230 kv Jauru-Porto Velho transmission line. SEMA identified 35 legally owned properties in the park by March 2016. The owners could sell the land directly to the state, or to other landowners in Mato Grosso who needed legal conservation areas to compensate for degraded areas. A management plan is required before the park can be officially open to the public, and in March 2016 SEMA had plans to hire a company to prepare the plan. As of 2016 the park was supported by the
Amazon Region Protected Areas Program. ==Environment==
