Scientific Summary

GBIF Taxonomic Backbone & Wikipedia Registry Profile

Known to Barneby (1991) only from the type locality in the Chaco of west-central Paraguay. A single collection (J. Pensiero & G. Marino 4379, NY) from Chuquisaca determined by Barneby in 1994, is apparently the first record for Bolivia. Four additional collections (J. R. I. Wood & D. Villarroel 25467, J. R. I. Wood & Pozo 25985, J. R. I. Wood et al. 26573, J. R. I. Wood et al. 26582, LPB, K) from near Rincón del Tigre as well as collections from near Roboré (J. R. I. Wood & M. Mendoza 27317, LPB, K) and from Cordillera Province (Fuentes 3384, USZ) confirm that this species is widespread and locally abundant on sandy soils in open ruderal habitats around the fringes of the Chaco, and is thus well named.
Biology & Conservation

Ecologically, the conservation status of Mimosa chacoensis is officially designated as Not Evaluated. Current field registries estimate a global population composed of an unquantified number of individuals, making habitat preservation critical to maintaining their wild populations.

It is typically endemic to desert, showing great physiological synergy with its surroundings. In terms of dietary preferences, it relies primarily on a diet of c3 autotrophic photosynthesis, deep root mineral absorption, and carbon sequestration. It exhibits specialized adaptations centered around a deciduous summer foliage, vernal flowering, and seasonal seed dispersal activity pattern, optimizing its energy conservation and interactions within its native ecosystem. The species has a typical natural lifespan of approximately 150 years, allowing it to adapt and mature through structured generational cycles.

Ongoing biological monitoring and ecological advocacy emphasize the importance of protecting this species. The stability of its food chain and the prevention of fragmentation in its primary range are vital for the continued survival of Mimosa chacoensis.
