Species identified during biodiversity monitoring are classified based on official protection lists, local laws and regulations, and scientific literature on degrees of threat, rareness, endemicity, economic importance, species migration, and other parameters.

The degree of threat is determined based on international as well as national and state conservation lists. The conservation lists used include:

• IUCN (International Union for Conservation of Nature) Red List;
• MMA Ordinance No. 148/2022
• National List of Endangered Wildlife Species (MMA Ordinance No. 444/2014);
• Official National List of Endangered Flora Species (MMA Ordinance No. 443/2014)
• List of Threatened Brazilian Flora Species (MMA Ordinance No. 298/2019)
• National List of Invasive Alien Species (MMA Ordinance No. 2.546/2020)
