摘要

根据《欧盟生物多样性战略2030》的保护目标,到2030年,欧盟30%的陆地和海洋面积应得到法律保护。虽然实际目标和术语仍有待确定,但可以模拟该战略的可能影响,以供政策支持之用。该战略旨在通过留出森林和推广更接近自然的森林管理做法来加强保护。考虑芬兰的森林保护目标,采用欧洲林业动态模型(EFDM)对芬兰的森林资源进行了模拟。根据我们的模拟,在额外的保护下,总增长库存和净现值将低于照常经营。额外的保护导致在现有采伐水平下可用于木材供应的剩余森林地区加强采伐。这可能会削弱保护的积极生态影响。从目前的水平降低收获水平也不是一个可能的选择,因为预计未来对生物质的需求会增加,而供应不足,欧盟的政策旨在避免将资源开采的负面影响转移到欧盟以外。附加保护的可行性取决于实际实施和定义。

EU wood production vs. biodiversity goals – possible reconciliation in Finland?
ABSTRACT According to protection targets of EU Biodiversity Strategy 2030, 30% of EU’s land and sea area should be legally protected by 2030. While the actual targets and even terms are still to be defined, the strategy’s possible impacts can be simulated for policy support purposes. The strategy aims to increase protection by setting aside forests and extending closer-to-nature forest management practices. We simulated Finland’s forest resources with the European Forestry Dynamics Model (EFDM) considering the protection targets. According to our simulations, the total growing stock and net present value will be lower with the additional protection than by carrying on the business-as-usual management. The additional protection resulted in intensified harvesting in the remaining forest area available for wood supply with the current harvest level. This may weaken the positive ecological impacts of protection. Reducing the harvest level from the current level is not a likely alternative either, because the demand for biomass is predicted to increase in the future, while the supply is insufficient, and EU policies aim to avoid shifting the negative impacts of resource extraction outside the EU. The feasibility of the additional protection depends on the actual implementation and definitions.
