Importance of irrigation and plant size in the establishment success of different native species in a degraded ecosystem of central Chile

Abstract: SUMMARYIrrigation has frequently been considered a necessary step in reforesting open areas of semiarid ecosystems. However, the success of irrigation has mainly been assessed using young and small plants, typically younger than two years old. Few studies have explored whether irrigation is also important with older and larger plants, and if the use of larger plants may enhance reforestation success. We tested the effect of irrigation and plant size on survival and height growth of six tree species from the Me… Show more

“…As demonstrated in other studies, watering can increase survival and improve root growth during the establishment period, particularly when water supplements are applied during the summer season in semiarid environment [21,47,48,51,57]. However, our findings suggest that differences in water-acquisition strategies of root systems of South American Mediterranean tree species determine different capacity to survive under situations of severe drought.…”

“…As target species, we used Quillaja saponaria (deep-rooted) and Cryptocarya alba (shallow-rooted) saplings. Both are endemic Neotropical species widely distributed in central Chile (30° S-38° W) [50] and are commonly used in active restoration plans of degraded native forests, although with high heterogeneity in growth and survival [51].…”

“…En otros casos, como en la Sierra de Baza, las plantaciones han fracasado en su mayoría debido a la falta de humedad estival (Costa 2006), lo que demuestra que las condiciones microclimáticas locales no siempre son suficientes para la regeneración de T. baccata debido a la extrema sequedad del verano, incluso allí donde se repueble artificialmente. El factor riego, por tanto, es determinante para el éxito de las reforestaciones en ambientes mediterráneos, incluso fuera de la Cuenca, tal y como han experimentado Becerra et al (2013) en zonas costeras de clima mediterráneo del centro de Chile.…”

“…In these regions, water availability is the main abiotic factor limiting plant regeneration and reforestation processes (Fuentes et al 1986, Holmgren et al 2001, Gutiérrez et al 2007, Siles et al 2010, Becerra et al 2013. In semiarid regions, usually total precipitation increases with elevation, which, in addition to decreasing mean temperatures, reduces soil evaporation.…”
