Direct seeding of native tree species for dry forest restoration
Background and Aims: Dry forest is in extreme need of restoration given its high deforestation rates. For its restoration, direct seeding, which refers to the sowing of seeds directly in the soil, has been suggested.

| description | Background and Aims: Dry forest is in extreme need of restoration given its high deforestation rates. For its restoration, direct seeding, which refers to the sowing of seeds directly in the soil, has been suggested. The objective of this study was to evaluate the success of direct seeding of nine native tree species.Methods: Emergency was evaluated for 30 days and survival for one year for four early-successional and five late-successional tree species sown in habitats with different cover of herbs and trees in two areas under restoration in Morelos and Puebla, Mexico. Key results: The most successful species given emergence and seedling survival were the early successional trees Spondias purpurea (16.79%) in El Limón, and Senegalia macilenta (20.38%) in Teotlalco; the other tree species had <10% of success. In both localities, successional status of the sown tree species was not a good predictor of emergence percentage. The cover of herbaceous and trees favored the emergence of late-successional species, while the early-successional species did not respond to plant cover; the opposite was true for seedling survival: late-successional species did not respond to plant cover changes.Conclusions: The highest mortality was registered in those areas without restoration intervention due in part, to the lack of plant cover. Also, since tree performance varied greatly by successional status and among covers, we recommend: 1) using different combination of early and late-successional tree species for direct seeding under contrasting covers and 2) establishing a cover with fast-growing trees under which the seeds of species that benefit from shade are sown and 3) to favor natural succession to increase the success of direct seeding. |

Antecedentes y Objetivos: La selva estacionalmente seca requiere de acciones de restauración dadas sus altas tasas de deforestación. Para su restauración se ha sugerido el uso de la siembra directa, que se refiere a la colocación de semillas directamente en el suelo. El objetivo de este trabajo fue evaluar el éxito de la siembra directa de semillas de árboles de nueve especies nativas.Métodos: La emergencia se evaluó durante 30 días y la sobrevivencia después de un año para cuatro especies sucesionales tempranas y cinco tardías sembradas en hábitats con distinta cobertura de hierbas y árboles en dos áreas bajo restauración en Morelos y Puebla, México. Resultados clave: Las especies más exitosas por su emergencia y sobrevivencia de plántulas fueron las sucesionales tempranas: Spondias purpurea (16.79%) en El Limón y Senegalia macilenta (20.38%) en Teotlalco; el resto de las especies presentaron porcentajes de éxito de <10%. En ambas localidades, el estatus sucesional de las especies no explicó el porcentaje de emergencia. La cobertura de hierbas y árboles favoreció la emergencia de las especies tardías, mientras que las tempranas no respondieron a la cobertura; lo opuesto se observó con la sobrevivencia de las plántulas: las tardías no respondieron a los cambios en la cobertura vegetal.Conclusiones: La mayor mortalidad de plántulas se registró en los sitios sin intervención de restauración, debido en parte a la falta de cobertura vegetal. Dado que el éxito de las especies por estatus sucesional y entre coberturas fue altamente variable, se recomienda: 1) usar distintas combinaciones de semillas de especies tempranas y tardías para la siembra directa bajo coberturas contrastantes, 2) establecer una cobertura con árboles de rápido crecimiento bajo la cual se siembren las semillas de especies que se benefician de la sombra y, 3) favorecer la sucesión natural para aumentar el éxito de la siembra directa.
