Local Productive Arrangements nowadays are targets for local and regional development politics. This study aimed to identify, qualify and geographically limit the municipalities that are part of a potential Local Productive Arrangement of Forestry Base in the southeast of Rio Grande do Sul. The hierarchical grouping analysis was used to identify the existence of groups and the analysis of main components to qualify them. Afterwards, industrial cluster indicators were used to quantify the specificity of a sector within a region for the formed groups. The hierarchical grouping analysis established four groups of municipalities, presenting different levels of development referring to the forestry sector. It is concluded that there is a Local Productive Arrangement of Forestry Base in the studied area limited by the municipalities of Cachoeira do Sul, Pantano Grande, Dom Feliciano, Amaral Ferrador, Encruzilhada do Sul, Piratini and Canguçu.
