| Study area | Number of restoration trials established | Experimental treatments examined | Mean (+/- SE) early survival (%) |
| Veracruz | 4 | Land use history and site effect on mixed plantations | 45% + 7 after 1 year, 35.3% + 8 after 2 years |
| 1 | Performance of species selected by local people, improved establishment techniques | 60% + 8 after 17 months | |
| Oaxaca | 7 | Different combinations of tree species and soil types | 88% + 2, range 58-100% |
| Northern Argentina | 1 | Tree density, mixtures of different native species, use of exotics as nurse trees, vulnerability to pathogens under different treatments. |
Native species: <5 to 30%. Exotic species: usually >30%. |
| Southern Argentina | 2 | Herbivory, nurse-shrub protection, seedling age |
Zero without nurse shrubs. 36% (± 20) under nurse shrubs without protection 47% (± 24) under nurse shrubs with protection from herbivores |
| Central Chile | 5 | Irrigation, nurse plants | 47% ± 15 |
