人们越来越重视利用自然过程，包括河岸森林恢复，来加强水道的生态、水文和地貌功能。然而，我们对河岸林林内木材的供应和保留量如何随年龄变化的了解不足，推论通常基于陆地森林的数据。这对估计修复项目的效力和功能寿命提出了挑战。在本文中，我们使用河岸森林生长模型来表明，从森林开始生长到树木向大到足以抵抗河流运输和锚定堵塞的河道输送木材之间存在长达40-50年的滞后，从而增加了河道的复杂性和水力阻力。资源管理者需要考虑到由河岸林地恢复所促进的变化将发生的现实时间表，并可能需要考虑在森林发展时使用临时工程堵塞。
There is an increasing emphasis on using natural processes, including riparian forest restoration, to enhance the ecological, hydrological and geomorphological functioning of watercourses. However, we have insufficient knowledge on how the supply and retention of in‐channel wood from riparian forest stands changes with age, with inferences typically based on data from terrestrial forests. This presents a challenge in estimating the efficacy and functional lifespan of restoration projects. In this paper, we use a riparian forest growth model to show there is a lag of up to 40–50 years between the start of forest growth and trees delivering wood to the channel that is large enough to resist fluvial transport, anchor logjams and so increase channel complexity and hydraulic resistance. Resource managers need to account for realistic timescales over which changes promoted by riparian woodland restoration will occur and may need to consider using interim engineered logjams as the forest develops.
