1. Vegetation vertical structure is important for biodiversity and ecosystem service provision. In cities, however, while variation in the spatial extent and distribution of vegetation has been widely investigated, vertical vegetation structure and its potential drivers have not. Understanding how vegetation vertical structure varies across cities and identifying the potential drivers of this variation will improve the management of urban vegetation for biodiversity and ecosystem services. 2. We used light detection and ranging (LiDAR) data to quantify the vertical structure of vegetation across Brisbane, Australia, at 1-km(2) and 1-ha spatial scales and investigated how this structure varied in response to biophysical, socioeconomic, urban form and landscape structure variables. 3. Using model selection techniques, we found that landscape structure variables related to tree cover (tree cover extent and spatial configuration) best explained the vegetation vertical structure at both spatial scales. Biophysical and urban form variables were also important, but only in combination with landscape structure. 4. Mean vegetation vertical complexity, foliage projective cover and canopy height at a site all decreased as the treed proportion of the surrounding urban landscape decreased. In general, these vertical structure variables also increased where patches of vegetation were clustered together spatially. 5. Synthesis and applications. Using light detection and ranging (LiDAR) data and model selection techniques, we show that the extent and vertical structure of urban vegetation are not independent and that reduced extent and increased fragmentation of urban vegetation are associated with simplification of its vertical structure. If common, this relationship means that managing urban vegetation for biodiversity and ecosystem services should not focus solely on the amount of tree cover or green space present across cities, but also on identifying where interventions to improve vegetation vertical complexity are required. Our study provides important insights into where these locations may be in cities.

Retaining natural vegetation to safeguard biodiversity and humanity

Jeremy S. Simmonds, Andres Felipe Suarez-Castro, April E. Reside, James E. M. Watson, James R. Allan, Scott C. Atkinson, Pasquale Borrelli, Nigel Dudley, Stephen Edwards, Richard A. Fuller, Edward T. Game, Simon Linke, Sean L. Maxwell, Panos Panagos, Philippe Puydarrieux, Fabien Quetier, Rebecca K. Runting, Talitha Santini, Laura J. Sonter, Martine Maron

Summary: Global efforts to achieve internationally agreed goals such as reducing carbon emissions and halting biodiversity loss lack integration. To unify these goals, we have derived specific area-based targets for retaining natural and seminatural terrestrial vegetation worldwide. At least 50% of Earth's terrestrial surface needs to be preserved in order to contribute to biodiversity, climate, soil, and freshwater conservation objectives under 4 United Nations' resolutions.

Exploring the risks and benefits of flexibility in biodiversity offset location in a case study of migratory shorebirds

Nicole Shumway, Megan Saunders, Sam Nicol, Richard A. Fuller, Noam Ben-Moshe, Takuya Iwamura, Sun W. Kim, Nicholas J. Murray, James E. M. Watson, Martine Maron

Summary: Biodiversity offsets aim to counterbalance the impacts of development on species and ecosystems. The effectiveness of spatially flexible offsets, located further from the impact area, in achieving no net loss or better ecological outcomes compared to local offsets is uncertain. In the case study of migratory shorebirds, there were insufficient data to draw robust conclusions about the effectiveness and equivalence of distant habitat-based offsets. The potential benefits of spatially flexible offsets need to be evaluated against the increased risks to ensure effective offset placement.

Taiwan?s Breeding Bird Survey reveals very few declining species

Da-Li Lin, Jerome Chie-Jen Ko, Tatsuya Amano, Cheng-Te Hsu, Richard A. Fuller, Martine Maron, Meng-Wen Fan, Scott Pursner, Tsai-Yu Wu, Shih-Hung Wu, Wan-Jyun Chen, Elisa Bayraktarov, Taej Mundkur, Ruey-Shing Lin, Tzung-Su Ding, Yung-Jaan Lee, Pei-Fen Lee

Summary: This study models the population trajectories of 107 breeding bird species in Taiwan and develops multi-species indicators for forest, farmland, and introduced bird species. The results show that most species did not show significant changes, but some forest and farmland species declined rapidly. Additionally, the introduced species indicator grew more rapidly than native species indicators, posing a risk to native bird communities and ecosystem integrity.

Using empirical data analysis and expert opinion to identify farmland-associated bird species from their habitat associations

Da-Li Lin, Martine Maron, Tatsuya Amano, An-Yu Chang, Richard A. Fuller

Summary: Agricultural expansion poses a threat to biodiversity, and intensification of farming activities can decrease the diversity and abundance of farmland-associated species. This study developed an integrated approach using empirical data analysis and expert opinion to identify farmland-associated bird species in Taiwan. The results showed that the classifications of 104 species based on both methods were consistent, with 72.1% of the species classified consistently. The study highlights the importance of expert opinion in cases where empirical data are insufficient.

Exploring the role of boundary work in a social-ecological synthesis initiative

Barbara Schroeter, Claudia Sattler, Jean Paul Metzger, Jonathan R. Rhodes, Marie-Josee Fortin, Camila Hohlenwerger, L. Roman Carrasco, Oerjan Bodin

Summary: Inter- and transdisciplinary collaboration in environmental studies face the challenge of effectively communicating across disciplines to address pressing environmental challenges. This research brief evaluates the use of a boundary work approach in a synthesis group on socio-ecological systems, and discusses how it can integrate the knowledge of natural and social scientists. The results show that strategic selection of members, inclusion of boundary spanners, and prior identification of boundary concepts and objects can enhance collaboration and problem-solving in multidisciplinary teams.

Summary: Although some countries along the East Asian-Australasian Flyway have begun reporting population trends and identifying threats to migratory waterbirds, there is still limited systematic waterbird monitoring, hindering our understanding of the overall status of waterbird populations in the flyway. To address this, data from a citizen science project in Taiwan were used to examine recent population trends of 31 migratory waterbird species. The results showed varying trends among regions and identified the impacts of local land use and habitat loss in the Yellow Sea on the decline of migratory waterbirds in Taiwanese wetlands.

Minimum multipliers for fishery offsets in marine habitats vary depending on the no net loss goal

Deqiang Ma, Jonathan Rhodes, Martine Maron

Summary: Offsetting the impacts of development-induced marine habitat loss on fishery resources is crucial for ensuring seafood security. However, the potential benefits of marine habitat restoration for fishery resources have not been quantified. In this study, we use a case study of mangrove habitat offsets in Australia to determine the minimum restoration area needed to fully offset fishery losses caused by development projects.

Performance of habitat offsets for species conservation in dynamic human-modified landscapes

Jonathan R. Rhodes, Yan Liu, Agung Wahyudi, Martine Maron, Md Sayed Iftekhar, Shantala Brisbane

Summary: Biodiversity offsets are a popular policy tool for mitigating the impact of development on biodiversity. However, their success depends on complex interactions among socio-economic, ecological, and policy processes. Habitat surrogates are commonly used in offset policies to determine requirements, but this approach may lead to poor outcomes for species. Agency-led offsets delivered by a public agency are proposed as a potential solution because they can strategically choose offset sites that maximize outcomes for species. The success of this approach depends on patterns of development and offset site availability.

Redistribution of fishery benefits among commercial and recreational fishers caused by offsetting

Deqiang Ma, Jonathan Rhodes, Carissa J. Klein, Martine Maron

Summary: Biodiversity offsetting is a method used to offset the negative impacts of development on biodiversity. However, the redistribution of ecosystem services caused by offsets can affect the distribution of benefits among beneficiaries. This study compared the effects of two offset policy rules on the distribution of fishery economic benefits and losses.
