After the capybaras in Nordelta, a new animal species invades the countries: danger or advantage?

Invasion of lizards in Pilar: some moved inside the houses

The appearance of lizards in different private neighborhoods of Pilar aroused concern in the neighbors because many of them were found in the gardens, prowling near the swimming pools and moving not only through the galleries of the houses but even inside some houses. .

Just like last year, capybaras invaded Nordelta Now it is the turn of this other native species: the overo lizard Its coloration is dark with white transverse spots and its size is medium.

It has long hind limbs, a long head and very small, oval-shaped dorsal scales. The body can reach a length of approximately 40 centimeters or more (distance taken between the snout and the vent), but if we take into account the long tail, this length can be almost double. Its head is prolonged and laterally compressed.

The appearance of the overo lizard took place in the Parque Irízar, Pellegrini IV and Mirasoles neighborhoods and the specialists assure that there is no need to fear them. The sighting of this type of reptiles is due to the drought and the increase in real estate developments that in sectors where these species have their habitat, leads them to move. Due to soil movements and intervention, they began to look for new areas to inhabit.

for the biologist Nicholas Garcia Romero These are “friendly giants”, a species native to the area that easily adapts to peri-urban environments. They are not aggressiveThey are going to try to avoid contact with domestic species, for example, unless they feel very threatened,” the specialist told different local media.

“They are not dangerous at all. The lizard will always choose to escape and not to face. When they feel threatened, they cut off their own tail,” García Romero specified. Likewise, the biologist clarified that in the hypothetical case of feeling very cornered or threatened and incurring an eventual attack, they are animals that do not have the possibility of causing great damage.

Graciela Capodoglio, a member of the Natural Heritage Association that is in charge of the Pilar Nature Reserve, spoke with Daily Pillar and I also bring peace of mind to the neighbors: “They are animals that do not eat anything that is bigger than an egg, they do not put people at risk and since they are cold-blooded they cannot transmit diseases.”

“They are even beneficial,” explained the environmentalist, adding that “people should try to keep them in their homes” since “They control pests of mice and snails.

Regarding their presence in the place, Capodoglio stressed that this species of lizards “is part of the native fauna that was here before we arrived. They appear due to lack of water and because their habitat is being invaded.”

For its part, Javier Goloschtein, Director of Biodiversity of the Pilar Municipality, “the presence of lizards in the area is normal” and highlighted “their important biological role in the ecosystem.”

“In the Pilar Reserve we have a significant number of these lizards and when we recover an animal that entered a house we release it in that reserve. They are common animals in Pilar as were the capybaras in the wetland”, Goloschtein specified to TN.

In addition, he attributed their presence to the heat wave that is going through the province of Buenos Aires: “They are looking for cooler and more humid places, which today are urban since we are increasingly occupying their distribution and the area they inhabit.”

warned that there is no trying to capture or manipulate them because “they defend themselves with their tails, they have sharp claws and a very strong jaw”. And he concluded: They are not pets. they are native fauna, these types of animals should not be commercialized”.
