Every May 22, the International Day for Biological Diversity once again brings to the forefront an increasingly visible issue in Argentina: the accelerated disappearance of native species. The degradation of ecosystems, urban expansion, and the pressure of human activities are already affecting emblematic animals and plants in different regions of the country.
Various environmental and scientific organizations warn that the loss of biodiversity has ceased to be a future threat and has transformed into a current crisis. In this context, species such as the maned wolf, the yellow cardinal, the Patagonian frog, and the field mint represent some of the most critical cases.
Moreover, specialists emphasize that conservation does not depend solely on protected areas. It also requires environmental education, biological corridors, and sustained policies that allow for the preservation of increasingly fragmented natural habitats.
The situation highlights how human pressure profoundly modifies Argentine ecosystems, from the northern grasslands to the Patagonian lagoons and the Misiones jungle.
The maned wolf and the yellow cardinal, among the most threatened species
The maned wolf, the largest canid in South America, primarily inhabits the northern and central-eastern regions of Argentina. Although historically persecuted due to popular myths, today it faces much more complex threats linked to agricultural and urban expansion.
Road accidents have become one of the main causes of death for this species. Added to this are the fragmentation of habitats and the illegal capture of young specimens.
On the other hand, the yellow cardinal is experiencing an equally delicate situation. Its striking plumage and unique song have led to decades of intense illegal capture for the cage bird trade.
The decline of its populations is also associated with the destruction of forests and grasslands. Currently, various conservation networks are working on rescue, breeding, and reintroduction programs in the province of Buenos Aires and other regions of the country.
Amphibians and plants struggling to survive
In the province of Neuquén, the Patagonian frog faces a drastic alteration of its natural ecosystem. The introduction of invasive exotic fish, such as rainbow trout and perch, has altered the biological balance of the lagoons where it originally lived.
Additionally, drought and overgrazing worsen the environmental conditions. Many populations survive in temporary water bodies that are increasingly vulnerable to climate change.
The situation of the field mint is even more extreme. This aromatic plant native to southern Misiones is on the brink of total disappearance, and currently, only one wild specimen in its natural state is known.
However, scientific projects developed in the Osununú Natural Reserve have allowed the reproduction of dozens of individuals in nurseries, generating hope to prevent its definitive extinction.
What other Argentine species are also threatened?
The environmental crisis also affects numerous emblematic species of Argentina. Among them is the jaguar, considered the largest feline in the Americas, whose wild population remains fragmented in Misiones, Chaco, and the northern Yungas.
The pampas deer, the Patagonian huemul, the giant armadillo, and the hooded grebe, a bird exclusive to Santa Cruz affected by invasive species and environmental changes, are also in critical situations.
In marine ecosystems, pollution and overfishing impact dolphins, sharks, and coastal birds. Meanwhile, in native forests, deforestation continues to reduce crucial areas for the survival of hundreds of species.
Specialists warn that protecting biodiversity also means preserving water sources, regulating the climate, and sustaining productive activities linked to healthy ecosystems.
In this scenario, the joint work of scientists, communities, environmental organizations, and public agencies emerges as a central tool to halt the loss of species and recover essential environments for the ecological balance of the country.
