Although ecological restoration is widely used to combat environmental degradation, very few studies have evaluated the cost-effectiveness of this approach. We examine the potential impact of forest restoration on the value of multiple ecosystem services across four dryland areas in Latin America, by estimating the net value of ecosystem service benefits under different reforestation scenarios. The values of selected ecosystem services were mapped under each scenario, supported by the use of a spatially explicit model of forest dynamics. We explored the economic potential of a change in land use from livestock grazing to restored native forest using different discount rates and performed a cost–benefit analysis of three restoration scenarios. Results show that passive restoration is cost-effective for all study areas on the basis of the services analyzed, whereas the benefits from active restoration are generally outweighed by the relatively high costs involved. These findings were found to be relatively insensitive to discount rate but were sensitive to the market value of carbon. Substantial variation in values was recorded between study areas, demonstrating that ecosystem service values are strongly context specific. However, spatial analysis enabled localized areas of net benefits to be identified, indicating the value of this approach for identifying the relative costs and benefits of restoration interventions across a landscape.

Summary: 1. The development of ecological networks could enhance the ability of species to disperse across fragmented landscapes and could mitigate against the negative impacts of climate change. The development of such networks will require widespread ecological restoration at the landscape scale, which is likely to be costly. However, little information is available regarding the cost‐effectiveness of restoration approaches.2. We address this knowledge gap by examining the potential impact of landscape‐scale habitat restoration on the value of multiple ecosystem services across the catchment of the River Frome in Dorset, England. This was achieved by mapping the market value of four ecosystem services (carbon storage, crops, livestock and timber) under three different restoration scenarios, estimating restoration costs, and calculating net benefits.3. The non‐market value of additional services (cultural, aesthetic and recreational value) was elicited from local stakeholders using an online survey tool. Flood risk was assessed using a scoring approach. Spatial Multi‐Criteria Analysis (MCA) was conducted, incorporating both market and non‐market values, to evaluate the relative benefits of restoration scenarios. These were compared with impacts of restoration on biodiversity value.4. Multi‐Criteria Analysis results consistently ranked restoration scenarios above a non‐restoration comparator, reflecting the increased provision of multiple ecosystem services. Restoration scenarios also provided benefits to biodiversity, in terms of increased species richness and habitat connectivity. However, restoration costs consistently exceeded the market value of ecosystem services.5. Synthesis and applications. Establishment of ecological networks through ecological restoration is unlikely to deliver net economic benefits in landscapes dominated by agricultural land use. This reflects the high costs of ecological restoration in such landscapes. The cost‐effectiveness of ecological networks will depend on how the benefits provided to people are valued, and on how the value of non‐market benefits are weighted against the costs of reduced agricultural and timber production. Future plans for ecological restoration should incorporate local stakeholder values, to ensure that benefits to people are maximised.

Species turnover is ubiquitous. However, it remains unknown whether certain types of species are consistently gained or lost across different habitats. Here, we analysed the trajectories of 1827 plant species over time intervals of up to 78 years at 141 sites across mountain summits, forests, and lowland grasslands in Europe. We found, albeit with relatively small effect sizes, displacements of smaller‐ by larger‐ranged species across habitats. Communities shifted in parallel towards more nutrient‐demanding species, with species from nutrient‐rich habitats having larger ranges. Because these species are typically strong competitors, declines of smaller‐ranged species could reflect not only abiotic drivers of global change, but also biotic pressure from increased competition. The ubiquitous component of turnover based on species range size we found here may partially reconcile findings of no net loss in local diversity with global species loss, and link community‐scale turnover to macroecological processes such as biotic homogenisation.

Summary: Conservation management is increasingly being required to support both the provision of ecosystem services and maintenance of biodiversity. However, trade‐offs can occur between biodiversity and ecosystems services. We examine whether such trade‐offs can be resolved through landscape‐scale approaches to management. We analysed the biodiversity value and provision of selected ecosystem services (carbon storage, recreation, aesthetic and timber value) on patches of lowland heathland in the southern English county of Dorset. We used transition matrices of vegetation dynamics across 112 heathland patches to forecast biodiversity and ecosystem service provision on patches of different sizes over a 27‐year timeline. Management scenarios simulated the removal of scrub and woodland and compared (i) no management (NM); (ii) all heaths managed equally (AM); and management focused on (iii) small heaths (SM) and (iv) large heaths (LM). Results highlighted a number of trade‐offs. Whereas biodiversity values were significantly lower in woodland than in dry and humid heath, timber, carbon storage and aesthetic values were highest in woodland. While recreation value was positively related to dry heath area, it was negatively related to woodland area. Multicriteria analysis ranked NM highest for aesthetic value, carbon storage and timber value. In contrast, SM ranked highest for recreation and LM highest for biodiversity value. In no scenario did the current site‐based approach to management (AM) rank highest. Synthesis and applications. Biodiversity–ecosystem service trade‐offs are reported in lowland heathland, an ecosystem type of high conservation value. Trade‐offs can be addressed through a landscape‐scale approach to management, by varying interventions according to heathland patch size. Specifically, if management for biodiversity conservation is focused on larger patches, the aesthetic, carbon storage and timber value of smaller patches would increase, as a result of woody succession. In this way, individual heathland patches of either relatively high biodiversity value or high value for provision of ecosystem services could both potentially be delivered at the landscape scale.

Community-based approaches to decision-making in the management of protected areas are increasingly being implemented in many areas. However information on the outcome of these approaches for conservation is often lacking. In this study, the effectiveness of community-based approaches for conservation of biodiversity was examined in Annapurna Conservation Area (ACA) (Nepal) through a combination of ecological assessments and social surveys undertaken both within and outwith ACA. Forest basal area and tree species diversity were found to be significantly higher inside ACA than in neighbouring areas outside. The mean density of cut tree stumps was significantly lower inside ACA, associated with a decline in use of fuelwood as an energy source over the past decade. Social surveys also indicated that wild animal populations have increased inside ACA since the inception of community-based conservation. Observations of animal track counts, pellet counts and direct observations of selected species such as barking deer (Muntiacus muntjak) and Himalayan tahr (Hemitragus jemlahicus) indicated higher abundances within ACA. The community-based management has been successful in delivering conservation benefits in ACA, attributable to changing patterns of resource use and behaviour among local communities, increased control of local communities over their local resources, increased conservation awareness among local people resulting from environmental education, and the development and strengthening of local institutions such as Conservation Area Management Committees (CAMC). However, these positive achievements are threatened by the current political instability in Nepal.
