Resumen

En la región del Medio Oeste de Brasil, los fragmentos de bosque del bioma del bosque atlántico están desconectados del paisaje y tienen poca resistencia. En busca de posibles técnicas de restauración, este estudio tuvo como objetivo evaluar las interacciones de las perchas artificiales con algunas técnicas de nucleación, con el fin de confirmar la hipótesis de que la combinación de estas técnicas aumenta la diversidad de semillas y regenerantes en el área. El diseño experimental fue en bloques al azar, con cinco tratamientos y  repeticiones. Los tratamientos de restauración incluyeron (1) solo perchas de control; (2) perchas con recolectores de propágulos; (3) perchas con transposición de ramas; (4) perchas con apoyo alimentario; y (5) perchas con transposición de ramas y apoyo alimentario. El experimento se llevó a cabo en un área degradada, previamente colonizada por pastizales, cerca de un remanente de bosque (ecossistema de referencia). Después de 365 días, se identificaron los regenerantes (numero de especies e individuos). En la diversidad de regenerantes hubo un aumento significativo con la interacción de más de una técnica de nucleación, destacando la eficiencia de combinar perchas artificiales con colectores (T2) y transposición de ramas con apoyo alimentario (T5). Con base en los resultados, se puede decir que el uso de perchas artificiales combinadas con otras técnicas de nucleación favorece el reclutamiento de plántulas de especies zoochóricas y aumenta el banco de semillas a través del forrajeo de las aves. Se cree que esta técnica es económicamente viable y tiene el potencial de ser utilizada en proyectos de restauración.
