| description | Background and Aims: The ability to carry out ecological restoration in a practical way requires considering not only the probability of success in ecological terms, but also the economic costs. As a contribution to the advancement of integrated ecological and economic studies in ecological restoration, the objectives of this work were to (i) estimate the direct costs of direct seeding and planting nursery specimens of P. flexuosa var. depressa, a species considered as “framework” of the restoration in arid zones of the Monte region in Argentina, (ii) evaluate the costs in relation to the percentages of germination and establishment in the results, and (iii) compare rural and petroleum economic scenarios.Methods: Calculations were based on direct costs. To determine the incidence of the percentage of establishment in the cost of each activity, a reduction to unit values was made (a seed or plant). The direct costs of each input or activity of sowing seeds or planting were appropriated to these units, considering mortality and multiplied by the number of specimens expected per hectare.Key results: Although the establishment in the field of nursery seedlings of P. flexuosa var. depressa is much higher than the percentage of survival in direct seeding (91% vs. 11,4%), direct seeding resulted in a cost reduction of 40% in relation to outplanting. The very notable difference in salaries in the hydrocarbon business sector vs. rural wages generates an increase of four times the total values in dollars. Conclusions: It is concluded that direct seeding should receive priority in scientific research, and technical-economic assistance for rural producers. |

Antecedentes y Objetivos: La capacidad para llevar a cabo una restauración ecológica en forma práctica requiere que sea considerada tanto la probabilidad de éxito en términos ecológicos como los costos económicos. Como aporte al estudio que integra dichos aspectos, los objetivos de este trabajo fueron: (i) estimar los costos directos de la siembra de semillas y la plantación de ejemplares de vivero de P. flexuosa var. depressa, una especie considerada “marco” o “fundante” de la restauración en zonas áridas del territorio biogeográfico del Monte de Argentina, (ii) evaluar la incidencia de los porcentajes de germinación y/o establecimiento de plántulas en los resultados, y (iii) comparar dos escenarios económicos, uno rural y otro petrolero. Métodos: Los cálculos se efectuaron a partir de costos directos. Para determinar la incidencia en el porcentaje de establecimiento, se realizó una reducción a valores unitarios (una semilla o planta). Se apropiaron costos para cada insumo y/o actividad de siembra de semillas o plantación a estas unidades, considerando la mortalidad. Para obtener el costo total, se redujo a valor unitario (una semilla o plántula) la incidencia de cada actividad o insumo, y se multiplicó por la cantidad de ejemplares esperados por hectárea. Resultados clave: Si bien el establecimiento en campo de plántulas de vivero de P. flexuosa var. depressa es muy superior al porcentaje de sobrevivencia a partir de siembras de semillas (91% vs. 11%), la siembra resultó en una reducción de costos de 40% en relación con la plantación. La diferencia muy notable de salarios de empresas privadas del sector hidrocarburífero vs. empleados rurales, genera un incremento de cuatro veces el valor directo en dólares en el escenario petrolero. Conclusiones: Se concluye que la siembra directa debe recibir prioridad en investigación científica y asistencia técnico-económica para productores rurales.
