"Former Chilean vegetation was dominated by sclerophyllous forests (Gajardo 1994), which have been degraded to a fragmented scrubland.
Santiago City, the Capital of Chile, is located approximately 550 m above sea level, and shelters ca. 6 million inhabitants within its 15,800 km2 area. Santiago occupies a large extension of the valley of the Metropolitan Region, which is one of the most representative areas of the Chilean Mediterranean ecosystem (di Castri 1968). Accelerated human population growth in absence of sustainable management resulted in a fast and chaotic expansion of the city towards the piedmont area of the Andean mountain range. Currently, urbanized areas have reached 1,000 m above sea level, causing an important loss of natural habitats and environmental problems such as atmospheric pollution due to dust, loss of soils, inundations, and shortage of green areas (Hajek et al. 1990, Romero et al. 1999, GORE-RM 2000)
There is scarce evidence on the impacts of the rapid and dramatic modification on the landscape of central Chile on the native fauna. However, Romero et al. (1999) and Romero & Órdenes (2004) indicated that the fast growth of Santiago City had polluted soils, water and air, and that it had affected the water retention and infiltration capacities of the soil, produced fragmentation of the natural vegetation, and the interruption of corridors for the native fauna. At a national scale, other studies have reveled important effects of landscape modifications (towards human use) on biodiversity, such as the southern cases of the urban area of Concepción (Pauchard et al. 2006) and Lake Bundi (Peña-Cortés 2006). Currently, assigning conservation categories to native flora and fauna in Chile are fundamentally based on the concepts of populations and species (Glade 1998, Núñez et al. 1997, Cofré & Marquet 1999, Díaz-Páez & Ortiz 2003). This approach frequently results in a subjective evaluation of "endangered species" which does not take into account the acutla situation of the environments those species inhabits.

Gebiete in Ost-Santiago
Das östliche Santiago gliedert sich grob in folgende Gebiete:
- Lo Barnecho
- Las Condes (https://es.wikipedia.org/wiki/Las_Condes) (San Carlos de Apoquindo, finanzielles Zentrum der Stadt "Sanhattan")
- La Reina (https://es.wikipedia.org/wiki/La_Reina) (Eingeklemmt zwischen Las Condes (https://es.wikipedia.org/wiki/Las_Condes) und Peñalolén (https://es.wikipedia.org/wiki/Pe%C3%B1alol%C3%A9n))
- Peñalolén (https://es.wikipedia.org/wiki/Pe%C3%B1alol%C3%A9n)
- La Florida (https://es.wikipedia.org/wiki/La_Florida_%28Chile%29)
- Puente Alto (https://es.wikipedia.org/wiki/Puente_Alto)
Unklarheiten: Angaben zur Lage und Grösse der Gemeinde Lo Barnecho sind widersprüchlich. Womöglich hängt es damit zusammen, dass die Gemeinde ein recht grosses Gebiet umfasst, wovon nur ein kleiner Teil im nordöstlichen Zipfel noch zum Stadtgebiet von Santiago ("Gran Santiago") selbst gehört, während der Metropolitanraum von Santiago auch noch ländlichere Bereiche der Gemeinde umfasst, die nicht mehr in den Stadtraum fallen (da es sich um schwer zugängliche Andengebirge der Sierra Ramon handelt).
