Freshwater ecosystems and their bordering wetlands and riparian zones are vital for human society and biological diversity. Yet, they are among the most degraded ecosystems, where sharp declines in biodiversity are driven by human activities, such as hydropower development, agriculture, forestry, and fisheries. Because freshwater ecosystems are characterized by strongly reciprocal linkages with surrounding landscapes, human activities that encroach on or degrade riparian zones ultimately lead to declines in freshwater–riparian ecosystem functioning. We synthesized results of a symposium on freshwater, riparian, and wetland processes and interactions and analyzed some of the major problems associated with improving freshwater and riparian research and management. Three distinct barriers are the lack of involvement of local people in conservation research and management, absence of adequate measurement of biodiversity in freshwater and riparian ecosystems, and separate legislation and policy on riparian and freshwater management. Based on our findings, we argue that freshwater and riparian research and conservation efforts should be integrated more explicitly. Best practices for overcoming the 3 major barriers to improved conservation include more and sustainable use of traditional and other forms of local ecological knowledge, choosing appropriate metrics for ecological research and monitoring of restoration efforts, and mirroring the close links between riparian and freshwater ecosystems in legislation and policy. Integrating these 3 angles in conservation science and practice will provide substantial benefits in addressing the freshwater biodiversity crisis.

Sustainable Forest Management (SFM) is crucial for biodiversity conservation. Although it should be assessed by monitoring the diversity of multiple taxonomic groups, most current SFM criteria and indicators account only for trees or consider indirect biodiversity proxies.Several projects performed multi-taxon sampling to investigate the effects of forest management on biodiversity, but through heterogeneous sampling approaches that hamper the identification of general trends, and the broad-scale inference for designing SFM.The COST Action BOTTOMS-UP (CA18207) established a network of researchers involved in 41 projects on European forest multi-taxon biodiversity across 13 European countries. We provide an overview of the sampling approaches to multi-taxon biodiversity, standing trees and deadwood in the form of an operational handbook for nine different taxonomic groups and for the sampling of standing trees and lying deadwood. For each of these forest components, we provide two standards that differ in spatial scale and effort, and give specific instructions for the comparability across standards, taxonomic groups and studies. This handbook derives from an effort of networking and synthesis and represents a pragmatic synthesis and an important step forward to direct monitoring of forest biodiversity, in Europe and elsewhere
