Forest management globally affects the ecosystem services, especially those related to ecosystem functioning and biodiversity conservation, by altering forest structure and composition. The degree of alteration was related to the intensity and type of harvesting; therefore, the major silvicultural challenge is to develop alternatives to mitigate climate change and maintain forest functions and biodiversity while also providing acceptable levels of timber production. Variable retention forestry (VRF) is a highly flexible concept, with continuity of forest cover, structure, function, and species composition, thereby supporting multiple economic, environmental, and cultural goals. This special issue provides an overview of the concepts and applications related to VRF implementation around the world. It shows that VRF has been applied globally for several decades, with varying levels and retention types, depending on local conditions and the economic importance of forestry. The challenges of VRF seem to differ to some extent on different continents, yet the general aims have been accepted in most of the continents. VRF has been successful in mitigating many effects of intensive harvesting, though in some forests of the world, the retention levels are too low to maintain acceptable levels of biodiversity and ecosystem functions. We conclude that an active collaboration between scientists and forest practitioners is needed to realize all of the opportunities provided by VRF in solving global forestry-related issues.

可变保留林业的生态观点

全球森林管理通过改变森林结构和组成,影响到生态系统服务,特别是与生态系统功能和生物多样性保护有关的服务。改变的程度与收获的强度和类型有关。因此,主要的造林挑战是开发替代方案以减轻气候变化并保持森林功能和生物多样性,同时还要提供可接受的木材产量。可变保留林业(VRF)是一个高度灵活的概念,具有连续的森林覆盖,结构,功能和物种组成,从而支持多个经济,环境和文化目标。本期特刊概述了与全球范围内VRF实施相关的概念和应用。它表明VRF已在全球应用了数十年,其水平和保留类型各不相同,这取决于当地条件和林业的经济重要性。在不同的大陆上,VRF的挑战似乎有所不同,但总体目标已在大多数大陆上接受。VRF已成功减轻了集约采伐的许多影响,尽管在世界上某些森林中,保留水平太低,无法维持可接受的生物多样性和生态系统功能水平。我们得出结论,需要科学家与森林从业者之间的积极合作,以实现VRF提供的解决全球林业相关问题的所有机会。在不同的大陆上,VRF的挑战似乎有所不同,但总体目标已在大多数大陆上接受。尽管在世界上一些森林中,VRF的保留水平太低,无法维持可接受的生物多样性和生态系统功能水平,但VRF已成功减轻了密集采伐的许多影响。我们得出结论,需要科学家与森林从业者之间的积极合作,以实现VRF提供的解决全球林业相关问题的所有机会。在不同的大陆上,VRF的挑战似乎有所不同,但总体目标已在大多数大陆上接受。VRF已成功减轻了集约采伐的许多影响,尽管在世界上某些森林中,保留水平太低,无法维持可接受的生物多样性和生态系统功能水平。我们得出结论,需要科学家与森林从业者之间的积极合作,以实现VRF提供的解决全球林业相关问题的所有机会。保留水平太低,无法维持可接受的生物多样性和生态系统功能水平。我们得出结论,需要科学家与森林从业者之间的积极合作,以实现VRF提供的解决全球林业相关问题的所有机会。保留水平太低,无法维持可接受的生物多样性和生态系统功能水平。我们得出结论,需要科学家与森林从业者之间的积极合作,以实现VRF提供的解决全球林业相关问题的所有机会。
