Reduced Rainfall Variability Reduces Growth of Nothofagus alessandrii Espinosa (Nothofagaceae) in the Maule Region, Chile [PDF]

Forests, 2022
Nothofagus alessandrii Espinosa is an endemic species of the coastal Maulino forest of central Chile that has historically been severely threatened by the reduction of its habitat and the isolation of its fragments. In addition, a gradual reduction in precipitation has been observed in recent years across its entire natural distribution area.

Cost-effective priority areas for the conservation of the Maulino coastal forest and Cost-effectiveness gains by considering climate change effects in reserve network planning of Nothofagus alessandrii (Ruil) [PDF]

, 2022
The most common vegetation in the Maule region of central Chile is sclerophyllous forest. The microclimate weather on the west oriented hillsides of the coastal range of the Maule region, however, allows the occurrence of the mesophyllous Maulino coastal forest (Torres-Díaz, et al., 2007; Santelices et al., 2011).

Characterizing reference sites to inform restoration of the last remnants of the endangered Nothofagus alessandrii forest ecosystem

Forest Ecosystems
The ecological restoration of threatened ecosystems is a global priority, particularly for those with only a few remaining intact fragments. A critical first step in restoring such ecosystems is the development of restoration targets based on the ...

Climate variability and forest fires in central and south‐central Chile

Ecosphere, Volume 9, Issue 4, April 2018., 2018
Abstract This paper evaluates the relationship between fire occurrence (number and burned area) and climate variability (precipitation and maximum temperatures) across central and south‐central Chile (32°–43° S) during recent decades (1976–2013). This region sustains the largest proportion of the Chilean population, contains ecologically important ...
