Regeneration of Sebastiania commersoniana (Euphorbiaceae) in relation to livestock and distance from forest in the mountains of central Argentina.

Regeneration of Sebastiania commersoniana (Euphorbiaceae) in relation to livestock and distance from forest in the mountains of central Argentina. Understanding the regeneration requirements of native woody species is important to guide forest conservation and restoration activities. We evaluated th...

Regeneration of Sebastiania commersoniana (Euphorbiaceae) in relation to livestock and distance from forest in the mountains of central Argentina. Understanding the regeneration requirements of native woody species is important to guide forest conservation and restoration activities. We evaluated the regeneration niche of Sebastiania commersoniana in relation to vegetation, soil and light comparing microsites with and without seedling in two paddocks with high and low livestock density and at three distances from the edges of forest patches dominated by the species: -2 m (inside the forest), 1 m and 3 m (outside the forest). We also analyzed seedling density and proportion of browsed stems. The seedlings were found in microsites with abundant herbaceous vegetation and low soil compaction. Seedling density was 134 % higher with low livestock density than with high livestock density outside the forest, showing no difference inside, and decreased abruptly with increasing distance from forest edge. The proportion of browsed stems was 13 times higher with high livestock density than with low livestock density. We conclude that establishment may be favored at microsites with conserved vegetation and soil; that seedling recruitment may be restricted to the forest patches proximity; and that reduction of livestock density may promote regeneration of S. commersoniana. Entender los requerimientos de regeneración de especies leñosas es importante para guiar prácticas de conservación y restauración de los bosques. Evaluamos el nicho de regeneración de Sebastiania commersoniana en relación a la vegetación, suelo y luminosidad comparando micrositios con y sin renoval en dos potreros con densidad de ganado alta y baja y a tres distancias del borde de los parches de bosque dominados por la especie: -2 m (dentro del bosque), 1 m y 3 m (fuera del bosque). También evaluamos la densidad de renovales y la proporción de tallos ramoneados. Los renovales se encontraron en micrositios con abundante vegetación herbácea y suelo poco compactado. La densidad de renovales fue un 134 % mayor con baja densidad de ganado que con alta fuera del bosque, sin diferencias dentro, y disminuyó marcadamente al aumentar la distancia al borde. La proporción de tallos ramoneados fue 13 veces mayor ante alta densidad de ganado que ante baja. Concluimos que el establecimiento puede verse favorecido en micrositios con vegetación y suelo conservados; que el reclutamiento de renovales puede encontrarse limitado a las cercanías de los parches de bosque, y que la reducción en densidad de ganado puede favorecer la regeneración de la especie.
