Increasing urbanization worldwide calls for more sustainable urban development. Simultaneously, the global biodiversity crisis accentuates the need of fostering biodiversity within cities. Policies supporting urban nature conservation need to understand people's acceptance of biodiversity‐friendly greenspace management. We surveyed more than 2,000 people in 19 European cities about their attitudes toward near‐natural urban grassland management in public greenspaces, and related their responses to nine sociocultural parameters. Results reveal that people across Europe can support urban biodiversity, yet within the frames of a generally tidy appearance of public greenery. Younger people and those using greenspaces for a greater variety of activities were more likely to favor biodiversity‐friendly greenspace management. Additionally, people who were aware of the meaning of biodiversity and those stating responsibility for biodiversity conservation particularly supported biodiversity‐friendly greenspace management. Our results point at explicit measures like environmental education to increase public acceptance of policies that facilitate nature conservation within cities.

In the last decades, some European cities have undergone important changes in search of a more sustainable development. This is the case for the city of Bilbao (Bizkaia, Basque Country), where a Greenbelt has been maintained surrounding the urban areas allowing the periurban areas to deliver ecosystem services (ES) to society. However, the role of the different ecosystems in the provision of ES is not the same, which can lead to conflicts among them. The aim of this study is to analyze the synergies and trade-offs among the eight most important ES in the Bilbao Metropolitan Greenbelt (BMG) to orient their management strategies towards more multifunctional landscapes. We mapped the ES and overlapped them looking for the most relevant areas for the provision of multiple ES and areas that are mostly lacking ES provision. We identify also existing ES trade-offs and synergies between ES using correlations so that managers can prioritize preservation efforts of land use types in the rest of the area. The results show that provisioning ES had trade-offs with regulating and cultural ES and the latter showed synergies between them. The former are mainly delivered by semi-natural ecosystems, while regulating and cultural ES are delivered mainly by natural ecosystems. Moreover, the most relevant areas for the provision of multiple ES were proposed as potential components of a Green Infrastructure (GI). Their identification and ES bundles could help decision-makers to orient their management strategies towards sustainability in metropolitan areas.

Sustainable development has to be based on scientific knowledge, social agreements, and political decisions. This study aimed to analyse the implementation of the ecosystem services approach (ESA) in the spatial planning of the Basque Country, via the co-creation of knowledge. This paper uses a proposal for a regional green infrastructure (GI) to examine the co-creation of knowledge process. It addresses the community of practice; a process of co-creation of knowledge through workshops and meeting, SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis using an online survey, and mapping and identification of the multifunctional areas that provide ecosystem services (ES) to develop a GI. Results indicate that ESA has been included in spatial planning actions at different scales (biosphere reserve, metropolitan area, and region). This subsequently created an avenue for understanding the political necessities at play, so that scientists can develop useful tools for sustainable development. The findings also draw attention to the importance of establishing a constructive and mutually comprehensible dialogue between politicians, technical experts and scientists. For ES to be part of spatial planning, ESA has to be taken into account at the beginning of the planning process. We conclude that building bridges between science and spatial planning can help establish science-based management guidelines and tools that help enhance the sustainability of the territory.

In the last decade, the population of the white-backed woodpecker (Dendrocopos leucotos lilfordi) (WBW) in Navarre has been reduced mainly due to the loss of suitable habitat for this species from intensive forest management, leading almost to its extinction. This study aimed to identify the key structural elements of breeding habitats of the WBW and analyze their effect on the composition of the saproxylic fungi community within the habitats. In the Special Area of Conservation, namely Quinto Real in Navarre, 20 circular plots (500 m²) and 10 transects (150–300 m) were located inside and outside WBW territories. Within each sample plot, forest structure, deadwood, microhabitats, regeneration, and saproxylic fungi community were studied. The results showed that the key elements in the WBW territories were high trees, high diversity of deadwood (with a high presence of big and late-decay deadwood), high snag volume, and high microhabitat diversity. Although the past management is also evident in the variability of some of those characteristics, this species is well adapted to different structural and compositional conditions of the territory. The saproxylic fungi community was richer among the WBW territories, and in those areas, the presence of Fomes fomentarius was high, compared to non-WBW territories where it was not present. In conclusion, to maintain and protect the studied population, it is necessary to implement sustainable management that guarantees the conservation of the key elements for the WBW territories (structural heterogeneity and high deadwood diversity) in order to increase the suitability of the habitat for WBWs.
