The wildfires in the Pantanal wetlands, the world's largest tropical wetland, have raged the region since August, threatening the habitats of local wild lives.
To fight the flames, a makeshift command post has been set up, bringing together nearly 100 firefighters, environmentalist and staff members from wildlife services.
According to a group of firefighters, they had to take a boat for approximately 40 minutes to reach a site across the river to put out the fire there, which started in early August but has reignited repeatedly afterwards.
Such recurring fire incidents are commonly seen during the dry season in the Pantanal wetlands over the past years.
Water levels decrease during the dry season and rise again in the rainy season in the Pantanal wetlands. Yet, the dry season has lengthened while the rainy season has shortened in recent years, with insufficient rainfall during the latter.
As a result, the upstream areas that are supposed to supply water to the wetlands are unable to provide adequate water now.
"The water supply to the wetlands has decreased, the time of water duration in the region is shorter. As a consequence, the wetlands dry out more quickly as the time they are exposed to the sun get longer, making it easier for these fires to get in," said William Assuncao, an analyst from the Chico Mendes Institute for Biodiversity Conservation, who has been working on forest fire prevention since 2010.
Biologists said the fires in the Pantanal wetlands not only have directly cause the deaths of numerous animals, but also severely damaged their habitats.
"The hyacinth macaw primarily feeds on two types of fruits that come from two specific palm trees in the Pantanal region. Wildfires that destroy these fruits prevent the macaws from feeding. Additionally, the wildfire has also devastated their nests. These birds stay on some large trees, so when the fire passes and the trees fall, these macaws would lose their nests," said biologist Bruno Henrique Grossi Carvalho.
