Documented records of Tapirus terrestris (Perissodactyla, Tapiridae) and Myrmecophaga tridactyla (Pilosa, Myrmecophagidae) in the north of the Cuña Boscosa santafesina (Santa Fe, Argentina)
Evidence of occurrence of Lowland Tapir (Tapirus terrestris) and Giant Anteater (Myrmecophaga tridactyla) in the province of Santa Fe, Argentina, is scarce, mainly in the case of the tapir whose current occurrence is still debated. Between the 22nd and 24th of February 2020, both species, categorized as “Vulnerable” both nationally and internationally, were recorded and documented 28 km north of the town of Villa Guillermina (Santa Fe), confirming their current presence in the province. Records were made in the north of the Cuña Boscosa santafesina, a region of approximately 10,000 km2 composed of various types of forests, palm groves, savannas and marshes characteristic of the Humid Chaco ecoregion. These environments continue towards the Province of Chaco, constituting a remnant or biological corridor that increase the available habitat for these threatened species. Some factors that constitute potential threats to these species, such as livestock activity, hunting pressure, presence of domestic dogs, grassland burning and deforestation, were observed in the area. The importance of conserving the environments of the Humid Chaco ecoregion locatedin the north of the province of Santa Fe that are underrepresented in the Provincial System of Natural Protected Areas is highlighted because these contain species with conservation priority such as tapir and Giant Anteater in addition to presenting the greater biodiversity within the provincial territory.

description |
Evidence of occurrence of Lowland Tapir (Tapirus terrestris) and Giant Anteater (Myrmecophaga tridactyla) in the province of Santa Fe, Argentina, is scarce, mainly in the case of the tapir whose current occurrence is still debated. Between the 22nd and 24th of February 2020, both species, categorized as “Vulnerable” both nationally and internationally, were recorded and documented 28 km north of the town of Villa Guillermina (Santa Fe), confirming their current presence in the province. Records were made in the north of the Cuña Boscosa santafesina, a region of approximately 10,000 km2 composed of various types of forests, palm groves, savannas and marshes characteristic of the Humid Chaco ecoregion. These environments continue towards the Province of Chaco, constituting a remnant or biological corridor that increase the available habitat for these threatened species. Some factors that constitute potential threats to these species, such as livestock activity, hunting pressure, presence of domestic dogs, grassland burning and deforestation, were observed in the area. The importance of conserving the environments of the Humid Chaco ecoregion locatedin the north of the province of Santa Fe that are underrepresented in the Provincial System of Natural Protected Areas is highlighted because these contain species with conservation priority such as tapir and Giant Anteater in addition to presenting the greater biodiversity within the provincial territory. |

Wet Chaco, Mammals, Endangered Species, Biological Corridors Evidence of occurrence of Lowland Tapir (Tapirus terrestris) and Giant Anteater (Myrmecophaga tridactyla) in the province of Santa Fe, Argentina, is scarce, mainly in the case of the tapir whose current occurrence is still debated. Between the 22nd and 24th of February 2020, both species, categorized as “Vulnerable” both nationally and internationally, were recorded and documented 28 km north of the town of Villa Guillermina (Santa Fe), confirming their current presence in the province.

These environments continue towards the Province of Chaco, constituting a remnant or biological corridor that increase the available habitat for these threatened species.

La Cuña Boscosa santafesina se extiende por un territorio de aproximadamente 10.000 km2 conformado por Bosques altos o mixtos, Quebrachales y Algarrobales, que alternan con abras graminosas, y un gran número de arroyos y cañadas que la atraviesan. Estos ambientes se comunican hacia el norte con ambientes del Chaco Húmedo de la Provincia de Chaco, constituyendo un importante corredor biológico para especies amenazadas como Tapirus terrestris y Myrmecophaga tridactyla, categorizadas como “Vulnerables” a nivel nacional. Entre los días 22 y 24 de febrero de 2020, ambas especies fueron registradas y documentadas unos 28 km al norte de la localidad de Villa Guillermina (Santa Fe), confirmando la presencia actual de las mismas en territorio santafesino. Es posible que los ambientes que conforman y acompañan a los arroyos y cañadas de la región se encuentren funcionando como vías de traslado para ambas especies. Algunos factores locales como la interacción con el ganado vacuno, la presión de cacería, la presencia de perros domésticos, la variación hídrica y la quema de pastizales podrían explicar la dinámica de estas especies en la región. Se destaca la importancia de continuar estudiando y de conservar los ambientes del norte de la provincia de Santa Fe por ser los más ricos en biodiversidad dentro del territorio provincial, a la vez que se encuentran poco representados en el Sistema Provincial de Áreas Naturales Protegidas.
