CASTILLO QUIROZ, David et al. Atriplex canescens (Pursh) Nutt. a multifunctional species of the semi-arid zones of north America: a review. Rev. mex. de cienc. forestales [online]. 2021, vol.12, n.67, pp.4-26.  Epub 25-Out-2021. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v12i67.821.

Atriplex canescens is a native species widely distributed in semi-arid areas of North America, from northern Mexico to the western United States. This review aims to present the information published for the last 25 years on its taxonomy, geographic distribution, habitat, current and potential uses, and threats to its habitat. This review shows that the main use of A. canescens is the production of forage for the feeding of bovine, goat and ovine livestock. Equally prominent is the use of this species in the rehabilitation of degraded soils, carbon sequestration and the prevention of soil erosion, as well as in phytoremediation of soils contaminated by industrial wastes. In addition, A. canescens has a wide potential in the biotechnological field, as biological control, biofuel and source of drought- and salinity-tolerant genes. The consumption of flowers, fruits, leaves and roots of this species has also been important for the indigenous communities. However, despite its wide distribution, this species faces threats, such as land-use change, competition with invasive species and reduction of connectivity among populations. In summary, A. canescens is a multifunctional species, that demands further knowledge for its sustainable management and preservation.
