Tree Influence on Grasslands in the Parguayan Chaco
Resumen: A common problem of grasslands in the semi-arid Central Chaco of Paraguay is the competition exerted by invading woody species. There is, however, an increasing awareness of the positive influences of individual trees, particularly Algarrobo (Prosopis alba and P. nigra) on the associated grassland, beyond the recreational and esthetical values of a park like woodland and the offer of shade and protection for livestock.
