Background and aims: The “ombusillo”, Phytolacca tetramera, is a rare plant endemic to the northeast Buenos Aires province, Argentina. The objective of this work is to provide a more accurate approximation of its distribution area, to evaluate the conservation status of the species and to list the threats to its conservation.
M&M: The occurrence sites were obtained from herbarium specimens, databases, bibliography, and fieldwork. We delimited geographic nuclei, or potential subpopulations, for groups of “ombusillos”. We surveyed the activities that threaten the survival of the species and finally the conservation status was evaluated using the IUCN criterion B1 (extent of occurrence).
Results: Phytolacca tetramera is currently restricted to the coast of the Río de la Plata between 4 and 15 m asl, from the district of La Plata to the Samborombón Bay. It has an extension of presence of 4313.714 km2, in which four geographic nuclei were identified. In accordance with IUCN criterion B1, we propose the category Endangered B1ab(i,iii) for P. tetramera. The threats to the survival of the species are diverse and need further studies, urbanization being one of the most serious.
Conclusions: Due to the restricted geographical extension of P. tetramera and its possible threats, it is essential to carry out actions for the conservation of this species. Among the priority actions for the future, it is essential to know more about its dispersal capacity and regeneration niche. |

Introducción y objetivos: El ombusillo, Phytolacca tetramera, es una planta rara, endémica del noreste de la provincia de Buenos Aires, Argentina. El objetivo de este trabajo es proporcionar información detallada y actualizada del área de distribución de la especie, evaluar su estado de conservación y discutir las amenazas para su conservación. M&M: Los sitios de ocurrencia de la especie se obtuvieron a partir de material de herbario, bases de datos, bibliografía y viajes de campo. Delimitamos núcleos geográficos (potenciales subpoblaciones) para los grupos de ombusillos. Relevamos las posibles amenazas mediante observaciones a campo y evaluamos el estado de conservación usando el criterio B1 de la UICN (extensión de presencia). Resultados: Phytolacca tetramera está restringida en la actualidad al litoral del Río de la Plata entre las cotas de 4 y 15 msnm, desde el partido de La Plata hasta la Bahía Samborombón. Posee una extensión de presencia de 4313,714 km2, en los cuales se identificaron cuatro núcleos geográficos. De acuerdo con el criterio B1 de la UICN, proponemos la categoría En Peligro B1ab(i,iii) para P. tetramera. Las amenazas a la supervivencia de la especie son diversas, aunque deben ser mejor estudiadas, siendo la urbanización una de las más importantes. Conclusiones: Debido a la extensión geográfica restringida de P. tetramera y a sus posibles amenazas, resulta imprescindible llevar a cabo acciones para la conservación de esta especie. Dentro de las acciones prioritarias a futuro es fundamental conocer más sobre su capacidad de dispersión y nicho de regeneración.
