Efecto de la cobertura y de la fertilización en el desarrollo de plantas de Nothofagus alessandrii cultivadas en contenedor [PDF]
Bosque, 2011 Nothofagus alessandrii is an endangered species. Yet, available information for the propagation and nursery cultivation of this species is conspicuously lacking. To this end, we studied the effect of cover and fertilization on early growth of nursery seedlings over one growing season.

Current and potential distribution areas for Nothofagus alessandrii, an endangeredtree species from central Chile [PDF]
Ciencia E Investigacion Agraria, 2012 Nothofagus alessandrii ("ruil") is an endangered species native to the Maule Coastal Forest of central Chile. Previous studies have demonstrated that the current distribution of this species and rates of deforestation and fragmentation present a serious threat to the species.

The decline of an endangered temperate ecosystem: the ruil (Nothofagus alessandrii) forest in central Chile [PDF]
Biodiversity and Conservation, 1998 We describe the current state of the ruil (Nothofagus alessandrii) forest, a rare and endemic temperate forest in central Chile. Because of a long history of land-use, the ruil forest has suffered intense deforestation and fragmentation. By 1991, there remained 352.2 ha of forest in 183 fragments, most of them small and regular and a few large and ...

1998El ruil es un árbol de 30 a 60 m de altura con diámetros que fluctúan entre los 0,7 a 2,0 m o más, si las condiciones son adecuadas para su desarrollo. Cuando crece en altitud, próximo a los límites de la vegetación árborea, se achaparra, lo que constituye una característica general de las Fagáceas.

Southern Forests: a Journal of Forest Science, 2022
The endemic ruil (Nothofagus alessandrii Espinosa) forest is one of the most endangered forest ecosystems in central Chile, where its regeneration is challenged by factors such as low seedling germination capacity and recently by fire. In this study, we sampled 36 plots (625 m2 each) within the very restricted distribution range of N.

New Forests, 2019
Ruil (Nothofagus alessandrii) is an endangered keystone species from the Mediterranean climate zone of Chile. Ruil’s fragile state of conservation urges development of restoration programs, but specific protocols for nursery production and field establishment that ensure plant survival are largely unknown. Therefore, we examined the effect on nitrogen (

Abstract The ruil (Nothofagus alessandrii Espinosa) forest is one of the most endangered-endemic forest ecosystem in central Chile. The species is classified as shade- intolerant, but at the early stages of development the species behave as shade- tolerant, and its transition from shade to sun is unknown.
