Effective planning of a large-scale restoration project is challenging, because of the range of factors that need to be considered (e.g. restoration of multiple habitats with varying degradation levels, multiple restoration goals and limited conservation resources). Ecological restoration planning studies typically focus on biodiversity and ecosystem services, rather than employment and other co-benefits. Robust Offsetting (RobOff), a restoration planning tool, was used in a forest restoration project in Durban, South Africa, to plan forest restoration considering a mosaic of habitats with varying levels of degradation, diverse restoration actions, a limited budget and multiple (biodiversity, carbon stock and employment) goals. To achieve this, the restoration action currently being implemented (= current action) was compared to three restoration alternatives. The three restoration alternatives included (1) natural regeneration action; (2) carbon action; and (3) biodiversity action. The results supported biodiversity action as most beneficial in terms of maximizing biodiversity, carbon storage and job creation. Results showed that investing in biodiversity action is preferable to the status quo. RobOff ensured optimal allocation of limited resources to actions and habitats that have a potential to achieve higher biodiversity, carbon storage and job creation.
This Editorial of the International Journal of Biodiversity Science, Ecosystem Services & Management (IJBESM) marks the end of this Journal’s publications under Rudolf de Groot. He has been instrumental in bringing the concept of ecosystem services to the fore, through seminal publications, books, lectures, through founding and chairing the Ecosystem Services Partnership (ESP); and finally, through ‘adding the ecosystem services to IJBESM’. After almost 8 years as Editor-in-Chief, he has decided to step down and hand over to a next generation.In the final part of this co-written Editorial, Rudolf de Groot will look back one last time at some highlights of the past years, partly together with his editorial team. The first part of this Editorial introduces the new co-Editors in Chief and how they envision the future of the Journal. Berta Martin-Lopez (Leuphana University of Luneburg, Germany) and Alexander van Oudenhoven (Leiden University, Netherlands) have gladly accepted to take over as co-Editors in Chief of IJBESM. They are interdisciplinary scientists at the forefront of research on social-ecological systems, ecosystem services, ecosystem management and sustainability transformation. Both are heavily involved in the Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services (IPBES) and both have been actively involved with this Journal for several years. While acknowledging and building on the achievements of the last couple of years, they suggest a way forward for publishing research on human–nature relationships.
The production of sufficient food for an increasing global population while conserving natural capital is a major challenge to humanity. Tree-mediated ecosystem services are recognized as key features of more sustainable agroecosystems but the strategic management of tree attributes for ecosystem service provision is poorly understood. Six agroforestry and tree cover transition studies, spanning tropical/subtropical forest zones in three continents, were synthesized to assess the contribution of tree cover to the conservation of biodiversity and ecosystem services. Loss of native earthworm populations resulted in 76% lower soil macroporosity when shade trees were absent in coffee agriculture. Increased tree cover contributed to 53% increase in tea crop yield, maintained 93% of crop pollinators found in the natural forest and, in combination with nearby forest fragments, contributed to as much as 86% lower incidence for coffee berry borer. In certain contexts, shade trees contributed to negative effects resulting from increases in abundance of white stem borer and lacebugs and resulted in 60% reduction of endangered tree species compared to forest. Managing trees for ecosystem services requires understanding which tree species to include and how to manage them for different socio-ecological contexts. This knowledge needs to be shared and translated into viable options with farming communities.
Some ecosystem services (ES) bestow society with obvious tangible benefits such as nourishment from food and water (i.e. final ES), whereas other ES benefit society through complex pathways such as maintaining the resilience of ecosystems and the final ES they provide (i.e. intermediate ES). However, the term ‘intermediate ES’ has remained loosely defined and some authors are now questioning the term’s applicability. To uncover the meaning and origin of the intermediate ES term, we reviewed the literature from 2000 to 2016. We found that the term originated in economics (early 2000s), shifted into ecology in the late 2000s, and its use has grown since. Intermediate ES have been commonly defined as indirect benefits, less commonly as types of ecological components, and occasionally as supporting and regulating ES. We explore these analogies, provide a timeline of the term’s use, and discuss pros and cons of the terminology. We recommend that intermediate ES should be defined in specific (often local) contexts considering social factors such as demand for ES and if the service is a key step along an identifiable pathway toward final ES delivery – considerations we illustrate using coastal temperate forests as a case study.EDITED BY Matthias Schröter
Rewilding as a conservation strategy is gaining increasing scientific, political and public attention, yet empirical evaluations of its impacts remain scarce, especially with regards to ecosystem services. We provide evidence of the change in three ecosystem services (timber [provisioning], pollination [regulating], and aesthetics [cultural]) from up to 27 years of a moorland rewilding strategy in the Scottish Highlands using a chronosequence of rewilded plots and adjacent controls. These services were assessed in the field and using online surveys. We found that rewilding increased aboveground woody biomass and restored natural tree recruitment processes, although the latter only emerged after at least 15 years of rewilding. Rewilding caused a linear increase in perceived aesthetic quality over the first 27 years, but had no effect on pollination visitation rates. Thus, we conclude that rewilding can be used for ecosystem service recovery in moorland landscapes, but that results vary depending on the preferred service.EDITED BY John Haslett
As in other ecosystems, provision of ecosystem services from forests is uncertain because of stochastic weather conditions. In general, society is risk-averse, which means that factors increasing or decreasing the uncertainty in ecosystem services add a source of cost or value to society, measurement of which is lacking in the literature. This article suggests a method for calculating the impact of site-specific ecological conditions in Swedish forests on the economic value of uncertain ecosystem services in terms of timber and carbon sequestration. Applying econometric tools from economics and finance to time-series forest data in Sweden reveals that a site quality indicator adds positively to forest growth rate and decreases uncertainty in forest productivity and associated provision of ecosystem services. The importance of site quality is demonstrated by showing that a marginal increase in site quality can raise the economic value of timber and carbon sequestration by 9% and that neglecting uncertainty can underestimate the value of the contribution by 12%. These findings indicate that management practices improving site quality have the potential of raising the total economic value of forest ecosystem and stabilizing its volatility.EDITED BY Antonio Lara, Alexander van Oudenhoven
The mapping and assessment of ecosystems and their services, an initiative under the EU Biodiversity Strategy to 2020, sets the basis for national ecosystem assessments in EU Member States, including Greece. The highly diverse and heterogeneous Greek landscape provides multiple ecosystem services (ES) and benefits to society. However, the rich knowledge base corresponds to limited research to support a national ecosystem assessment in Greece. In this paper, we apply a rapid method to map ecosystem types and quantify ES supply provided by mountainous protected areas. Using habitat type level data, we created a detailed ecosystem type map that was used as a baseline to assess the supply of provisioning and regulating and maintenance ES. We also applied a site-oriented approach to record and score the ES supply in each protected area. Summing up individual ES supply resulted in a total ES supply map which was used to identify ES hot spot areas within the Greek Natura 2000 mountainous sites. The results: (1) corroborate the hypothesis that protected areas should be treated as high value bio-physical and social-cultural complexes accounting for a significant part of the national capital; (2) highlight data gaps at the national level and limitations of ES mapping methods under such data restrictions; (3) are intended to provide to stakeholders and decision-makers, baseline information for future applied research and conservation management actions.EDITED BY Matthias Schröter
Although the relationships between habitats and ecosystem services (ESs) have been acknowledged, investigating spatio-temporal change in these has received far less attention. This study assesses the influence of habitat changes on ES delivery across space and time, based on two time points some 60 years apart, 1946 and 2009. A 1946 aerial photo coverage of two catchments in Scotland was used to construct digital photo mosaics which were then visually interpreted and digitised to derive historic habitat maps. Using the Spatial Evidence for Natural Capital Evaluation (SENCE) mapping approach, the derived habitat maps were translated into ES maps. These were then compared with contemporary ES maps of the two catchments, using the same mapping methodology. Increases in provisioning ESs were associated with increases in intensively managed habitats, with reductions in supply capacity of other regulating and supporting ESs associated with loss of semi-natural habitats. ES delivery was affected not only by gross area changes in habitats over time, but also by changes in configuration and spatial distribution of constituent habitats, including fragmentation and connectivity. It is argued that understanding historic changes in ESs adds an important strand in providing baselines to inform options for current and future management of catchments.
The value of peatlands as archives for vegetation, landscape, climate, and human history is well known, but often neglected in conservation planning. Archive value is the potential to satisfy future (yet unknown) demands for information about the past. This study aims at assessing the comparative archive value of a set of peatlands, to identify the most similar alternatives for three peatlands and to estimate the archive loss in case of their destruction. Representative cores from 49 peatlands in the region were assessed with respect to age, depth, resolution, (in)completeness, evenness, and diversity of substrates, peat accumulation status, and thickness of every single substrate type. After using cluster analysis to identify archive types and the relatedness among peatlands, the archive value of each peatland was expressed as a proportion of the total regional archive. We found candidates for compensating the three threatened peatlands, but also identified other archives of high conservation interest according to our criteria. The outcomes appeared rather robust but were determined by the criteria, resolution, and algorithms chosen. This work presents a first step towards developing an objective and consistent evaluation procedure of peatland archives, allowing the archive value to be considered in conservation and management decisions.

This Special Issue aims to contribute to the emerging science on how to maintain and rehabilitate biodiversity and ecosystem services effectively in the tropics where agricultural expansion has shaped the landscapes. Food production as a provisioning ecosystem service dominates direct economic value and employment in roughly half the world. Its sustainability, or lack thereof, depends on how the trade-offs between human activities and ecosystem services, beyond the provision of food, are balanced and managed locally and globally.This Special Issue is a result of a research program by CGIAR Research Program on Forests, Trees and Agroforestry. This program ‘zooms out’ from the details of certification schemes as such and ask the broader questions of when, where and how certification responses arise to what types of issues, by whom they are initiated and what broader consequences they have.Complete list of articles are:Environmentally and socially responsible global production and trade of timber and tree crop commodities: certification as a transient issue-attention cycle response to ecological and social issuesBeria Leimona, Meine van Noordwijk, Dagmar Mithofer, Paolo CeruttiCertify and shift blame, or resolve issues?

ABSTRACT The degree to which invasive Acacia species affect South Africa’s livestock production has received little attention. We investigated the ecological impacts of Acacia mearnsii invasion on forage quality and quantity and on soil resources, along A. mearnsii invasion gradients, on South African rangelands and the subsequent conditions following clearing. Grazing capacity was reduced by 72% in densely invaded sites, whereas clearing improved grazing capacity by 66% relative to densely invaded sites within 5 years. In densely invaded sites total grass species basal cover was reduced by up to 42%. As a result, A. mearnsii reduced grazing capacity, from 2 to 8 ha required to support one large stock unit (ha/LSU) in uninvaded and densely invaded sites, respectively. Soil moisture content was lower in densely invaded sites compared with lightly invaded and cleared sites. Plant litter increased from 1.3% to 4.2%, carbon content of the soil increased from 2.0% to 4.0% and nitrogen concentrations increased from 0.1% to 0.2% in response to invasion by A. mearnsii. Clearing resulted in improved grazing capacity within 5 years. These results also showed that, if left uncontrolled, wattle species can reduce livestock carrying capacity within montane grasslands in South Africa. EDITED BY James Aronson
ABSTRACTSmall islands are of special interest for sustainable development because of their unique characteristics and vulnerabilities. They are ecologically fragile, have limited resources, are susceptible to natural disasters and climate change. This study reviews the literature on island ecosystems, their contribution in the delivery of five key Island Ecosystem Services (IES) and acting pressures and trade-offs associated with IES management. From a set of 1630 potential relevant papers, 273 were selected for analysis. Most of the selected papers focused on cultural IES, in the form of recreation, eco-tourism and gene pool protection. However, provisioning and regulating IES were also well represented in the literature. Most of the studies discussed different management strategies and pressures arising from human use of IES. A small subset investigated the links between island biodiversity and IES, and the contribution of IES to human well-being. This review highlights knowledge gaps in the literature ...
Cultural ecosystem services (CES) are widely acknowledged as important but are often neglected by ecosystem service assessments, leading to a representational bias. This reflects the methodological challenges associated with producing robust and repeatable CES valuations. Here we provide a comparative analysis of three approaches for non-monetary valuation of CES, namely a structured survey, participatory GIS (PGIS) and GPS tracking methods. These were used to assess both recreation and aesthetic value of habitats within the New Forest National Park, UK. The association of CES with habitats enabled results of all three methods to be visualised at the landscape scale using maps, strengthening their value to conservation management. Broadleaved woodland and heathland habitats were consistently valued highly for both CES, whereas agricultural land tended to be associated with low values. Results obtained by the different methods were positively correlated in 6 out of 10 comparisons, indicating a degree of consistency between them. The spatial distribution of CES values at the landscape scale was also generally consistent between the three methods. These results highlight the value of comparative analyses of CES for identifying robust results, providing a way forward for their inclusion in land management decision-making.EDITED BY Matthias Schröter
This study utilized the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) pollination model to investigate the impacts of using field data on ecosystem services mapping studies by using potential pollination services in Cumberland and Colchester counties in Nova Scotia, Canada, as a case study. The model was run using two different sources of data to inform the floral resource component of the model. First, the model was run driven by proxies and approximate values gathered from the literature. The second iteration of the model utilized field-based data to generate floral resource abundance and distribution values. Both models utilized honey bee-specific species preference data drawn from field observations and expert opinion in the literature. Results indicated an 8.1% increase in the amount of land designated as high quality when the model was informed by field-based data. Such discrepancies are important when considering the potential implications of ecosystem services mapping studies on policy. As a tool, ecosystem services mapping provides the opportunity to spatially evaluate the impact that different land-use planning regimes could have on the supply and provision of various ecosystem services. However, as its popularity rises, it is important to keep in mind the accuracy and resolution of the data used to inform the modelling process.
Riparian margins can provide a range of environmental, social, and production benefits both on-farm and off-farm. However, our understanding of the relative advantage between various riparian-margin management options is limited. We aim to advance this knowledge by modelling change in food provision, water quality regulation, contact recreation, and amenity ecosystem services in response to riparian-margin management. Estimations in performance were made under grazed; fenced 1 m-wide grass-strips; and fenced 5 m-wide multi-tier planted riparian margin scenarios within a lowland dairy farming landscape as typical in the North Island, New Zealand. Our study allows for simultaneous analysis across the range of ecosystem services (provisioning, regulating, and cultural) and across spatial scales (farm, river network, catchment) as relevant to current policy focus for riparian management. We show both grass-strips and multi-tier planted margins can maintain or increase production values, while also making important contributions to environmental stewardship and community values. Under a multi-tier planted margin scenario, provision of amenity values also increases. Importantly, we also show that riparian management alone is not adequate to address detrimental outcomes of land use on receiving environments, and should be part of wider farm management practices used to maximise opportunities for sustained ecosystem service provision. This is an important consideration for land management policies.
Soils are the foundation for cultivating ecosystem services in urban agriculture. Yet, variations in socio-environment characteristics of urbanization leads to variable soil properties and unequal distribution of ecosystem services like soil fertility. Thus, examining relationships among biophysical features and social dimensions of urban agricultural systems is necessary to understand soil functioning variation and to develop urban agricultural systems that promote equitable ecosystem service provisioning. In 25 urban community gardens in California, we examined two links between soil properties and neighborhood socio-demographics: (1) how groundcover management affects soil properties; and (2) how socio-demographics (and in particular, social advantage) can affect groundcover management and soil properties. We found that mulch groundcover improves soil fertility and water holding capacity in gardens, and that socio-demographic factors may affect people's access to mulch to affect soil properties: neighborhoods with measures of higher mobility (e.g., greater vehicle availability), but measures of poorer public/environmental health (e.g., poorer health care access) had more soil organic matter, higher soil nutrient content, and greater water holding capacity. However, we found indicators of high functioning soils in the absence of mulch, indicating that other factors like social networks and organizational support may be important for urban agricultural ecosystem services.
The ability of agricultural areas to produce non-commodity outputs in addition to food and fiber, i.e. multifunctionality, is increasingly at the core of policies promoting sustainability. Assessing the potential benefits for biodiversity and understanding tradeoffs among multiple ecosystem services (ES) from agricultural areas remain key challenges, especially in mountainous landscapes. Through a case-study approach, we assess the tradeoffs and synergies between the ES associated with agricultural areas. We map and assess the ES provided by seven study areas in northern Italy, aiming to provide guidance on the relationship between the agricultural land use intensity and provision of ES. In total, we performed a quantitative evaluation of 10 ES indicators, followed by their thematic aggregation and correlation analyses to gain a better understanding of the spatial ES tradeoffs. Our findings highlight that the transition to intensive forms of agricultural exploitation, in addition to the loss of habitats, also involves a reduction in cultural services.
Guayusa (Ilex guayusa) is a native tree of the western Amazon region grown by indigenous farmers in traditional agroforestry systems. Its leaves are used as a drink similar to tea, which is now commercialized and marketed outside of the Amazon. To assess the impacts from the early stages of commercial guayusa production, we conducted interviews in four commercial guayusa-producing communities with indigenous guayusa farmers in the Ecuadorian Amazon. We focus on their experiences and critically discuss and speculate about the socio-ecological implications of the expanding commercialization of guayusa, particularly in relation to propositions of this special issue. Results reveal that revenues from guayusa have not overtaken those from other cash crops. Commercializing guayusa can have benefits for farmers and the environment, provided that rigorous criteria that measure social and environmental impacts are adhered to. Furthermore, guaysa production is characterized by vertical integration where many individual farmers supply one processing and wholesale company in a short value chain fostering a locally tailored certification approach that is able to exert the continuation of the traditional agroforestry practices. Yet, sustainability initiatives, standards and certification only provide partial solutions for protecting ecosystem services in the Ecuadorian Amazon.EDITED BY Beria Leimona
Certification of adherence to social and environmental standards allows companies involved in the (global) trade of commodities to dissociate themselves from negative impacts in the public eye. It can go beyond compliance with legal requirements. Certification can be an attempt to shift blame to uncertified others, but it can also contribute to resolving the underlying issues of concern. We provide a framework for a study of when, where and how certification schemes emerge and evolve, with specific attention to the degree to which underlying issues get addressed. Three strands of literature are combined in this framework (1) the issue–attention cycle as a schematic representation of public concerns shaping policy responses; (2) the management swing potential defined as the gap between best and worst current production systems and the basis for defining standards and (3) global value chains that link distant producers and consumers, and the power relations along these chains, including standards and certification. Based on literature review, we introduce a set of four propositions that inform testable specific hypotheses. We outline questions for reviews, in subsequent papers of this issue, of the experience on timber, oil palm, coffee, cacao and rubber as tropical-forest-margin commodities dominated by global trade.EDITED BY Christian Albert
We compared and contrasted 11 European case studies to identify challenges and opportunities toward the operationalization of marine and coastal ecosystem service (MCES) assessments in Europe. This work is the output of a panel convened by the Marine Working Group of the Ecosystem Services Partnership in September 2016. The MCES assessments were used to (1) address multiple policy objectives simultaneously, (2) interpret EU-wide policies to smaller scales and (3) inform local decision-making. Most of the studies did inform decision makers, but only in a few cases, the outputs were applied or informed decision-making. Significant limitations among the 11 assessments were the absence of shared understanding of the ES concept, data and knowledge gaps, difficulties in accounting for marine social–ecological systems complexity and partial stakeholder involvement. The findings of the expert panel call for continuous involvement of MCES ‘end users’, integrated knowledge on marine social–ecological systems, defining thresholds to MCES use and raising awareness to the general public. Such improvements at the intersection of science, policy and practice are essential starting points toward building a stronger science foundation supporting management of European marine ecosystems.EDITED BY Sebastian Villasante
