Ecosystem Services of Large Wood: Mapping the Research Gap
2021
Zuzana Poledniková | Tomáš Galia
It is well known that large wood affects geomorphic processes and functions in rivers. It enhances the quality of the habitat but it can also cause a threat to the population. These processes and functions of the environment can be transformed into ecosystem (dis)services, which represent direct or indirect (dis)benefits that the society obtains from nature. The goal of this paper was to describe the current relations between large wood and ecosystem services and map the related knowledge gaps. Firstly, we conducted a systematic literature review that was elaborated according to the six-stage and PRISMA protocols and workflow diagram. We found 499 papers; however, only 137 were eligible for the following analyses. Secondly, we made a transformation of research information from the articles (<i>n</i> = 135) into ecosystem services. The highest number of ecosystem services detected in the articles belonged to the regulation and maintenance section (<i>n</i> = 126), followed by the provisioning (<i>n</i> = 15) and cultural (<i>n</i> = 11) sections. The detected classes with the highest frequency of studies were specific habitat creation and increased channel heterogeneity. The findings show that the number of research papers on this topic is still insufficient; however, anaylzing ecosystem services could be useful to advocate the presence of large wood in the rivers.
