“…According to Armenteras, Gast and Villarreal (2003), the progressive reduction in the size of habitat patches is a key indicator of the ecosystem fragmentation. This reduction in size may decrease the connectivity among habitats, which then reduces or restricts the ecological flow, affecting ecosystem processes and services (Rodríguez-Echeverry, Echeverría, Oyarzún, & Morales, 2017). Therefore, the forest ecosystem in the commune of Arauco may register a critical condition in relation to the sustainability of the species, processes and ecosystem services.…”

“…This forest has registered deforestation and fragmentation processes, which have been progressive over the last decades (Echeverría, Newton, Nahuelhual, Coomes, & Rey-Benayas, 2012;Rodríguez-Echeverry, Echeverría, Oyarzún, & Morales, 2018). Several studies have reported the direct consequences of LUC in the structure and composition of forest ecosystems (Echeverría, Newton, Lara, Rey-Benayas, & Coomes, 2007), hydric regime (Little, Lara, Mcphee, & Urrutia, 2009;Rodríguez-Echeverry, Echeverría, Oyarzún, & Morales, 2017), increases in erosion and degradation of the soil (Rodríguez-Echeverry, Echeverría, Oyarzún, & Morales, 2017), and diversity and richness of the fauna and flora (Rodríguez-Echeverry, Echeverría, & Nahuelhual, 2015;Simonetti, 2011).…”

The forest landscape of southern Chile, which includes Chilean temperate forest ecosystem, has been designated as a hotspot for biodiversity conservation. However, this landscape has been transformed by land-use change. A proper knowledge about how land-use change impact this ecosystem would provide crucial information for planning conservation strategies. At the commune of Arauco – Chile, the impact of the land-use change on the spatial pattern of native forest ecosystem from 1990 to 2010 was evaluated at the landscape level. This evaluation was carried out using satellite images, landscape metrics and spatially explicit models. The loss of native forest ecosystem was of 40.7% (loss rate of 4.39% per year). Conversely, the exotic species plantations increased more than 150%. The number patches of native forest ecosystem increased more than 130%. The size distribution of patches (<100 ha) increased more than 22%. The aggregation index of native forest ecosystem decreased from 62.5 to 40.1. The loss of native forest ecosystem was caused by the expansion of exotic species plantations, which was associated with substantial changes in the spatial pattern of the forest landscape. As a strategy for conservation of the native forest ecosystem we suggest a landscape approach, using the corridor–patch–matrix model. We recommend that this strategy be complemented with land-use planning. Moreover, this strategy must be supported by a framework of environmental policies. We also recommend strengthening the existing ecological restoration programmes and developing new programmes to restore the native forest ecosystem.

“…With the progressive forest loss/fragmentation the forest cover represents a reduced area consisting of scattered and isolated habitat patches, with no connectivity (Rodríguez-Echeverry et al, 2018a). Therefore, the evaluation of forest landscape changes allows a better understanding of their degree of integrity, functionality, and landscape characteristics (composition and spatial configuration) (Rodríguez-Echeverry et al, 2017). This evaluation is essential in landscapes with high species diversity and endemism combined with high forest habitat loss (Lindenmayer & Franklin, 2002;Rodríguez-Echeverry et al, 2015).…”

Currently, there is no precise information on the degree of transformation of Tropical Andes hotspot landscape and native ecosystems due to the intensification of agricultural and urban land-use. Proper knowledge of these changes would provide crucial information for planning conservation strategies. We evaluated the impact of the intensification of agricultural and urban land-use on the Inter-Andean Dry Forest and Tropical Montane Forest, both of which are categorized as Critically Endangered, and the state of the landscape in the High Rio Guayllabamba watershed, Ecuador, during the periods 1991–2005 and 2005–2017. The evaluation was carried out using Landsat satellite images of 30 x 30 m pixels and landscape metrics. We found an advanced state of landscape transformation. Since the 1990s, the loss of both ecosystems was largely caused by the conversion of forest to agriculture, resulting in substantial changes in the spatial configuration of these ecosystems. From 1991 to 2017, 19.8 % and 16.1 % of Inter-Andean Dry Forest and Tropical Montane Forest respectively, were converted to agriculture. The loss of Inter-Andean Dry Forest was 28 % and the number of forest patches increased by more than 150%. The loss of Tropical Montane Forest was 16.5 % and the number of forest patches increased by more than 300 %. The largest loss and fragmentation of forest cover occurred from 1991 to 2005. We suggested planning landscape-scale conservation, using the patch-corridor-matrix model. This model is appropriate given the current configuration of the landscape studied, with Inter-Andean Dry Forest and Tropical Montane Forest restricted to small patches sparsely distributed across the landscape.

“…Estos impactos se han generado por el aumento de la población humana, que ha transformado paisajes boscosos en paisajes antrópicos en las últimas décadas (Bai et al, 2011;Pan et al, 2013). Varios autores han evidenciado la necesidad de conservar la diversidad de hábitats de bosques nativos dentro de paisajes boscosos y antrópicos (Iverson et al, 2014), ya que esto ayudaría a mantener la diversidad de flora y fauna, y procesos y servicios ecosistémicos clave, que proveen múltiples beneficios para las poblaciones humanas que habitan estos tipos de paisajes (Delgado et al, 2013;Rodríguez-Echeverry et al, 2017).…”
