Study covers the entire Doce River Basin and will assist forest restoration actions through the calibration of ecological indicator targets


The Renova Foundation has been conducting a Forest Inventory of forested areas in the Doce River Basin. These diagnostic studies began in July 2019 and assess flora biodiversity and soil conditions near springs, riverbanks and water recharge areas.

The study will map the biodiversity of flora, soil conditions and landscapes near springs, riverbanks and water recharge areas. This is considered the largest forest inventory in progress in our country, covering 87,000 km², about 220 hectares of sample area and covering approximately 230 municipalities.

The studies will guide the Foundation’s restoration actions, making it possible to compare and measure the progress of the forest restoration process with the data and information from the Doce River Basin reference ecosystems. It is expected to be completed in 2020, providing reference environments for these activities. 

Understand how the inventory is done

Due to the broad scope of the Forest Inventory, its area of activity was divided into nine sub-basins: Suaçui, Piranga, Santo Antonio, Pontoes and Lagoas, Manhuaçu, Caratinga, Piracicaba, Santa Maria do Doce and Guandu. 

Sample units (UAs) are installed in forested areas. In these places, data are collected from the specimens of flora present there, such as height, diameter at breast height, which species, among others. A study is made of the diversity and density of native species, vegetation cover and cover of invasive species (weeds, grasses). From these data, reference ecosystems are created, which allow us to observe the process of natural regeneration at various stages of ecological succession and to understand which species adapt best to each type of environment.

The plants studied will receive a sign with a QR Code. Through the code, anyone can access information such as scientific and popular name, height, trunk diameter and crown size. The forest inventory will calibrate the targets of ecological indicators which are: diversity of native species, density of native species, vegetation cover and cover of invasive species (weeds, grasses).



The study takes place in the areas of springs, permanent preservation areas, river and stream banks and water recharge zones of the Doce River Basin. The results will be fundamental to identify the areas that need more attention in the forest restoration process. 

The results obtained with the Forest Inventory will be made available to the environmental agencies of Minas Gerais and Espirito Santo and can serve as a basis for strategic planning and development of environmental public policies for the Doce River Basin.
