We focus on natural resource management initiatives that involve a blend of formally constituted programs, informed by scientists, managed by various organisations, and implemented by practitioners and volunteers. We conduct a systematic search and analysis of relevant literature, identifying studies that seek to reveal or measure factors that influence the outcomes of these types of initiatives. We find two parallel, albeit somewhat disconnected strands of research: biophysical and socio-economic investigations. They conceptualise and measure success in different ways and thus identify different factors that contribute to success – using vastly different analytical approaches. Whilst the separation of biophysical and socio-economic investigations prevents us from undertaking a quantitative meta-analysis, by qualitatively blending insights from those bodies of work, we are able to identify a <em>likely pathway from socioeconomic drivers to ecological successes.</em> This pathway highlights that positive environmental change requires both social and ecological successes.

This requires prioritizing key sites and strengthening international collaboration and investment in less wealthy regions; yet progress has been limited by incomplete knowledge of how sites contribute to sustaining migratory populations and how sites are connected across seasons. Focusing on Mesoamerica's Five Great Forests (5GF) – the region's largest remaining and urgently threatened forests – we illustrate how information derived from the eBird participatory science platform can be used to assess the importance of nonbreeding sites for migratory birds and to identify “stewardship connections” between Mesoamerica and North America, based on abundance concentrations of shared species. We found that the 5GF support 20–46 % of the global populations of 16 Nearctic-Neotropical migratory species and ≥ 10 % of another 24 species outside of the breeding season. Key breeding grounds with stewardship connections to the 5GF include densely forested parts of the Northeastern U.S., Ontario and Québec, Minnesota and Wisconsin, the Mississippi Delta and Appalachian regions, and the Texas Hill Country. Our results provide evidence of the role of the 5GF as anchor points for migratory bird conservation and offer a powerful, data-driven communication tool to guide international investments and partnerships to protect these vital sites. More broadly, we demonstrate a flexible approach for leveraging participatory science information to identify cross-border connections around suites of shared species, with the aim of accelerating joint habitat stewardship for migratory birds.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Resumen&lt;/h3&gt;&lt;div&gt;Con el aumento del riesgo de extinción de las especies migratorias a nivel mundial, existe una necesidad urgente de proteger los lugares más importantes que utilizan los migrantes a lo largo de sus ciclos anuales.

By categorising reviewed studies into distinct stages (“Knowing,” “Guidelines,” and “Doing”), we identify a pronounced dominance of theoretical contributions coupled with pronounced geographical, ecological, and taxonomic biases. Such biases significantly constrain the utility of existing conservation knowledge for policy-making and practical interventions. Although rich and valuable scientific data is abundant, translating this information into actionable, practical knowledge, crucially needed for informed policy decisions and effective conservation practice, remains inadequate.

For nocturnally migrating birds, the consequences can be fatal. Attracted and disoriented by illuminated infrastructure, birds can become victims of collisions, especially when visibility is reduced by fog and clouds. Birds crossing large, predominantly dark bodies of water can suddenly be confronted with patches of lit coastal areas. In contrast, when flying over land along the coast, birds are sequentially confronted with lit areas and are likely to rely on different navigation cues. We deployed two ornithological radars in proximity along the Croatian coast: one at a light-polluted site and one at a near-natural site. The aim was to maximise the contrast in light pollution while keeping other site-specific factors similar. We monitored the consecutive spring migration seasons of 2023 and 2024 and modelled the effect of light pollution on the number of birds in the air, mean airspeeds and mean flight altitudes, considering atmospheric, temporal, and directional predictors. Our results are partially hampered by the fact that we had to exclude a second radar pair from the analysis due to a technical defect. Nevertheless, we found evidence for attraction towards light pollution of sea-crossing birds in the remaining radar pair. Furthermore, we found a significant contribution of light pollution to the reduction of mean airspeeds and altitudes, especially in an overcast context. Besides indicating disorientation, our results raise serious concerns about increased numbers of bird collisions associated with migration peaks and impaired visibility, even with lower-intensity light pollution.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"313 ","pages":"Article 111620"},"PeriodicalIF":4.4,"publicationDate":"2025-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145579322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding how these secondary forests develop back towards old-growthness and what factors affect this development can contribute significantly to the conservation efforts of the scarce mature forests. Based on the idea of the development cycle, we have categorized the plots of the three consecutive Spanish National Forest Inventories spanning three decades into eight sylvogenetic phases. This novel approach has allowed us to gain important insights on the development of forests in Spain. First, we have shown how historical management legacies still shape most forests of Spain, which show structures typical of very young forests, with mature phases virtually nonexistent. Despite this, during the span of the study, most forests have shown an advance in their development cycle. However, this advance seems to be slowing down in the recent years. The analysis of several anthropic and natural factors indicates that this deceleration seems correlated with an increase of the effects of climate change, in particular with the intensification of drought spells that forests are suffering. Given the expected intensification of droughts and other perturbations derived from climate change, we can expect that the natural development of Spanish forests will continue to slow down and even suffer further regression, thus slowing or impeding their path towards maturity.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"313 ","pages":"Article 111592"},"PeriodicalIF":4.4,"publicationDate":"2025-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145579380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
