“…This has been shown to occur elsewhere [ 2 , 9 , 17 ], especially along the transition between Mediterranean and Temperate bioclimatic zones. Additionally, previous research suggests that the overall flammability and fuel loads are higher in areas where invasive plant species have invaded native forests [ 18 – 21 ]. The regeneration of some invasive plant species is favored by fire, resulting in a positive feedback between invasive plant abundance and fire activity [ 22 – 24 ].…”

Landscape drivers of recent fire activity (2001-2017) in south-central Chile

In recent decades large fires have affected communities throughout central and southern Chile with great social and ecological consequences. Despite this high fire activity, the controls and drivers and the spatiotemporal pattern of fires are not well understood. To identify the large-scale trends and drivers of recent fire activity across six regions in south-central Chile (~32–40° S Latitude) we evaluated MODIS satellite-derived fire detections and compared this data with Chilean Forest Service records for the period 2001–2017. MODIS burned area estimates provide a spatially and temporally comprehensive record of fire activity across an important bioclimatic transition zone between dry Mediterranean shrublands/sclerophyllous forests and wetter deciduous-broadleaf evergreen forests. Results suggest fire activity was highly variable in any given year, with no statistically significant trend in the number of fires or mean annual area burned. Evaluation of the variables associated with spatiotemporal patterns of fire for the 2001–2017 period indicate vegetation type, biophysical conditions (e.g., elevation, slope), mean annual and seasonal climatic conditions (e.g., precipitation) and mean population density have the greatest influence on the probability of fire occurrence and burned area for any given year. Both the number of fires and annual area burned were greatest in warmer, biomass-rich lowland Bío-Bío and Araucanía regions. Resource selection analyses indicate fire ‘preferentially’ occurs in exotic plantation forests, mixed native-exotic forests, native sclerophyll forests, pasture lands and matorral, vegetation types that all provide abundant, flammable and connected biomass for burning. Structurally and compositionally homogenous exotic plantation forests may promote fire spread greater than native deciduous-Nothofagaceae forests which were once widespread in the southern parts of the study area. In the future, the coincidence of warmer and drier conditions in landscapes dominated by flammable and fuel-rich forest plantations and mixed native-exotic and sclerophyll forests are likely to further promote large fires in south-central Chile.

“…Some invasive species are notably difficult to control, such as microbial species, animals such as mice or pigs, or plants that produce very large numbers of seeds, accumulate large longlived seed banks in the soil, can resprout vigorously, or have early onset of reproduction (e.g. Richardson and Kluge 2008;Wilson et al 2011;García et al 2015;Dickie et al 2016). However, there are other invasive organisms with biological characteristics (e.g.…”

Ecology and management of invasive Pinaceae around the world: progress and challenges

Many species in the family Pinaceae are invaders. These species are relatively easy to control because of some of their intrinsic characteristics and because they are highly visible and easy to eliminate. Many Pinaceae species have been well studied because of their use in forestry and their invasive behavior in many countries. The impacts of invasive Pinaceae are not only ecological, but also economic and social. We review the ecology and management of Pinaceae invasions and explore how restoration of invaded areas should be addressed. There are many ways to prevent invasions and to deal with them. Planting less invasive species, better site selection, and invasion monitoring are used successfully in different parts of the world to prevent invasion. Mechanical and chemical methods are used effectively to control Pinaceae invasions. Control is more effective at the early stages of invasion. Old invasions are more problematic as their elimination is more expensive, and the restoration of native vegetation is challenging. In some areas, native vegetation cannot thrive after Pinaceae have been removed, and weeds colonize cleared areas. More attention is needed to prevent the initiation and spread of invasions by focusing control

“…Particularly G. monspessulana, originating from Mediterranean Europe, was observed in forest transects that were once affected by fire (García et al 2010). The spread of this species from the boundaries may also change the fire regime within native forests in the long-run facilitating its further spread (García et al 2015). Until now, both G. monspessulana and Acacia melanoxylon, are only sparsely present in forests.…”

Struggling to maintain native plant diversity in a peri-urban reserve surrounded by a highly anthropogenic matrix

High human density and land use intensity often coincide with biodiversity hotspots making peri-urban reserves a keystone for conserving natural remnants in a highly anthropogenic matrix. Particularly, intense propagule pressure by alien plant species can pose a threat to native biodiversity. However, little is known about the factors that determine invasibility and the role of roads and other human disturbances for such small protected areas. Within a peri-urban reserve close to the city of Concepción, south-central Chile, we investigated the influence of different site and landscape characteristics on the richness of native and alien plant species across different habitat (ruderal, road and forest sites) and forest types (native and alien dominated forests). Compared to other protected areas, alien species were frequently found in this reserve indicating the importance of urban areas as source for alien species. Aliens concentrate around disturbed ruderal and road sites, facilitating their spread into the reserve. Natural forest areas are less invaded until now. Within forests alien plant species richness was, however, positively associated to the proximity to disturbed landscapes. Forests dominated by alien tree species within the reserve are not the source for alien species within natural forests, but they negatively affect native species richness by replacing adequate seed sources. In order to prevent a further spread of alien species into peri-urban reserves, large scale anthropogenic disturbances should be minimized, already invaded sites must be monitored and buffer-zones protecting reserves from surrounding land use activities should be established.
