      abstract = {This article reports the results of a research about the  sustai- nability of extractive farmers in the Atlantic  slopes of Rio Grande do Sul. The extractive economy at  issue is related to a species usually known as leather fern  (Rumohra adiantiformis (G.Forest.) Ching). It is estimated  that 3,000 families in the region perform this  non-regulated activity, whi- ch is their only source of  income. The sustainability degree of farmers was calculated  from information related to environmental, social and eco-  nomic dimensions, and to productivity, stability, equity,  resilience, and autonomy criteria. The analysis focused on  the comparison among the In- dexes Related to Dimension  (IRD), Criteria (IRC) and Sustainability (IRS) of each kind  of production system. The results pointed to the existence  of four kinds of production systems, and three of them were  included in this research. The sustainability indexes  showed that the production system type 3 was the most  sustainable, followed by type 2 and, finally, type 1.},
