| Descripción: | [Introduction]: The evaluation of ecosystem services in different land-use systems in family farming facilitates the development of sustainable land-use strategies. [Objective]: To study the effects of different land uses, commonly applied in family farming in the Mbaracayu Forest Biosphere Reserve (Canindeyú, Paraguay), on the conservation of tree diversity and delivery of critical ecosystem services: above- and belowground carbon storage and supporting services rendered by soil. [Methods]: We determined the diversity of trees, the aboveground carbon and soil stocks, and chemical and physical soil properties in 7 farms with diverse land-use systems: disturbed native forest, agroforestry system with yerba mate, subsistence crops and pastures. In each sampling point, data of the tree and shrub individuals were recorded, and samples of the herbaceous stratum, litter, and soil were taken. [Results]: We found the highest rate of both diversity and above-ground carbon storage in the disturber native forests and agroforestry systems without significant differences between the two. The values of CEC and Ca+2 in the soil were higher in disturbed native forests compared to pastures, while the remaining land uses showed intermediate values. There were no significant differences between the different land-use types regarding carbon storage and the physical stability of the soils. Nonetheless, the pastures had the lowest soil qualities. [Conclusions]: We demonstrated that the altered native forests and agroforest systems with yerba mate promote better the conservation of tree diversity, carbon retention, and soil quality. |
