Ecosystem services tradeoffs arising from non-native tree plantation expansion in southern Chile

摘要: Abstract Non-native tree plantations (NNTP) are an increasingly relevant global source of timber. Their expansion may lead to tradeoffs with important local ecosystem services (ES) that need be evaluated for a sound and sustainable landscape planning. For mountain area in southern Chile, we assessed the effects NNTP potential timber-ES through spatial tradeoff typology based on ES supply variations. We changes prioritized (native timber supply, forage water regulation, recreation opportunities) probabilistic projection at two administrative levels (the municipality small, medium large farm properties). Results show triggered increase 361% expense decreases provision selected ES, such as (16.3%), native (9.4%), regulation (0.4%) opportunities (66.8%). Tradeoffs were restricted small geographic areas but considerably high terms magnitude losses. highest farms compared properties. corroborate arise from interplay several factors, type productivity, they site-specific scale dependent. If continue expand current rate (yearly 9.6%) under management (large monocultures), significant inevitable. These results can inform landowners, planners governments better anticipate mitigate arising afforestation.
