Improvement of animal production systems in mediterranean climate regions is limited by low availability and poor nutritional value of pasture resources in late summer and autumn. In a program of introduction and selection of perennial fodder trees and nitrogen-fixing plants, ultimately aimed at the long-term improvement of silvopastoral and agrosilvopastoral systems in the mediterranean-climate region of Chile, one of the best candidates found thus far is alfalfa arborea or tagasaste (Chamaecytisus proliferus spp palmensis), a shrub or small tree originated in La Palma, Canary Islands. Tagasaste has been successfully incorporated in animal production systems in parts of Australia, New Zealand and elsewhere. Small introduction plots have been established at eight sites in central Chile, where its potential value in dryland farming systems seems quite high. Tagasaste grew well in the per-humid zone reaching 88 to 100% of survival rate, and height growth between 1 to 1.8 m. In the arid zone, there are increasing limitations to achieve a high plant survival rate in the first summer. In this review, we discuss perspectives for acclimatization and use of Tagasaste in Chile, along with important aspects of its nutritive and agronomic value and its utilization by animals
