World Ranger Day was established internationally, and Brazil observes the date in recognition of its environmental rangers. The day honors professionals who protect national parks, reserves, and wildlife across the country. In Brazil, rangers play a crucial role in safeguarding biomes such as the Amazon, Cerrado, and Atlantic Forest. The observance also commemorates rangers who have died or been injured in the line of duty. Environmental agencies and conservation organizations mark the date with tributes and awareness campaigns.
