For decades, the marsh deer was on the brink of disappearing in Argentina. However, its recent change of category to “near threatened” reflects a promising recovery.
This progress is especially observed in the Iberá Wetlands in Corrientes. There, populations have grown steadily thanks to habitat protection.
Consequently, the species becomes an emblem of conservation. Moreover, it demonstrates that ecological restoration can reverse critical processes.
Coordinated actions that made recovery possible
The growth of the marsh deer is the result of coordinated work between organizations, communities, and authorities. Among them, the Rewilding Argentina Foundation stands out.
Likewise, the Iberá National Park played a central role in the protection of the ecosystem. The reduction of threats was key to this process.
On the other hand, the creation of a provincial reserve of 1.3 million hectares in 1983 marked a turning point. Subsequently, part of that area was reclassified as a national park.
Additionally, the control of poaching and the reduction of livestock presence allowed for natural recovery. Thus, the species returned to its habitat.
A key species of South American wetlands
The marsh deer is the largest in South America and is closely linked to wet environments. It prefers swamps and flooded areas where it finds food and shelter.
Moreover, it has a remarkable ability to adapt to drought periods. However, its survival depends on the conservation of wetlands.
Therefore, its presence indicates a healthy ecosystem. Consequently, its recovery benefits multiple species that share this environment.
Historically, it was affected by sport hunting and habitat loss. These factors drastically reduced its populations in several regions.
New strategies: translocation and population restoration
The province of Corrientes advanced with a law that allows the translocation of native species. This tool opens new possibilities for conservation.
In this regard, recovered specimens can be moved to regions where the species has disappeared. Thus, the aim is to restore populations in different provinces.
Additionally, initiatives are projected in areas like the Bermejo-Bermejito interfluve in Chaco. These actions are based on the success achieved in Iberá.
Therefore, the experience shows that recovery is possible if threats are eliminated. Long-term planning is fundamental.
Current challenges and the future of conservation
Despite the progress, some populations remain in critical condition. Regions like eastern Chaco and Formosa present greater risks.
Likewise, the historical expansion of the species to areas like Salta and Jujuy is no longer maintained. Consequently, there are areas where it is completely extinct.
Finally, the case of the marsh deer highlights the value of wetlands. Protecting these ecosystems is key to sustaining biodiversity and facing environmental change.
