Forest restoration is a promising solution to counteract climate change, biodiversity loss, and meet a host of socioeconomic objectives. While international initiatives highlight potential ...contributions of forest restoration as a win-win for people and nature, we lack detailed information on how frontline restoration practitioners are addressing this challenge on the ground. Here, we present a systematic assessment of motivations, scale, and costs of forest restoration implemented by 166 practitioners across 14 countries in Latin America. We found that forest restoration is motivated by interlinked objectives and accordingly, most restoration practitioners concurrently used multiple interventions spanning a range of intensity of inputs matched to the scale of individual projects. Project scale influenced strategy, with low-intensity interventions like natural regeneration implemented when operating at larger scales (≥500 ha). However, active tree planting remains the most frequently used intervention (included in >92 % of programs). Costs of establishing planted areas vary most broadly at the project level ($4445/ha ± 4841 over first 3 years) with little evidence of efficiencies of scale and with additional financial support ($964/ha/yr) required ~10 years past establishment. Moreover, monitoring added substantial additional costs, and we identified widespread misalignment between indicators measured and the most frequently expressed objective of restoring biodiversity. Our results emphasize that, while a promising range of new forest restoration interventions are being implemented across Latin America, lower-cost interventions, accessible and practical monitoring strategies, and better alignment between funding cycles and actual time frames required to achieve restoration objectives are urgently needed to support successful outcomes.
•Practitioners concurrently use diverse restoration approaches tailored to conditions.•Lower-cost strategies are implemented most often when operating at larger scales.•Active tree planting and growing is the most widely used forest restoration approach.•Longer-term funding would improve success of broadly used restoration approaches.•Monitoring efforts infrequently align with objectives of conserving biodiversity.
Landscape‐scale restoration requires stakeholder collaboration and recognition of diverse social and ecological motivations to achieve multiple benefits. Yet few landscape restoration projects have ...set and achieved shared social and ecological goals.
Mechanisms to integrate social and ecological motivations will differ in different landscapes. We provide examples from urban, agricultural, and mined landscapes to highlight how integration can achieve multiple benefits and help incentivize restoration.
Better communication of ecological and especially social benefits of restoration could increase motivation. Social and economic incentives from carbon markets are evident in agricultural landscapes, biodiversity offset schemes are unlikely to motivate restoration without proof‐of‐concept, and framing restoration in terms of ecosystem services shows promise.
Synthesis and applications. When setting restoration goals, it is important to recognize the diverse motivations that influence them. In doing so, and by evaluating both social and ecological benefits, we can better achieve desired restoration outcomes. Customizing incentives to cater for diverse stakeholder motivations could therefore encourage restoration projects.

The use of cars and trucks over the past century has remade American geography-pushing big cities ever outward toward suburbanization, spurring the growth of some small towns while hastening the ...decline of others, and spawning a new kind of commercial landscape marked by gas stations, drive-in restaurants, motels, tourist attractions, and countless other retail entities that express our national love affair with the open road. By its very nature, this landscape is ever changing, indeed ephemeral. What is new quickly becomes old and is soon forgotten. In this absorbing book, John Jakle and Keith Sculle ponder how "Roadside America" might be remembered, especially since so little physical evidence of its earliest years survives. In straightforward and lively prose, supplemented by copious illustrations-historic and modern photographs, advertising postcards, cartoons, roadmaps-they survey the ways in which automobility has transformed life in the United States. Asking how we might best commemorate and preserve this part of our past-which has been so vital economically and politically, so significant to the cultural aspirations of ordinary Americans, yet so often ignored by scholars who dismiss it as kitsch-they propose the development of an actual outdoor museum that would treat seriously the themes of our roadside history. Certainly, museums have been created for frontier pioneering, the rise of commercial agriculture, and the coming of water- and steam-powered industrialization and transportation, especially the railroad. Is now not the time, the authors ask, for a museum forcefully exploring the automobile's emergence and the changes it has brought to place and landscape? Such a museum need not deny the nostalgic appeal of roadsides past, but if done properly, it could also tell us much about what the authors describe as "the most important kind of place yet devised in the American experience." John A. Jakle is Emeritus Professor of Geography at the University of Illinois, Urbana-Champaign. Keith A. Sculle is the former head of research and education at the Illinois Historic Preservation Agency. They have coauthored such books as America's Main Street Hotels: Transiency and Community in the Early Automobile Age; Motoring: The Highway Experience in America; Fast Food: Roadside Restaurants in the Automobile Age; and The Gas Station in America.
Invasion of alien species is one of the main drivers of land degradation threatening both natural and managed ecosystems. Ecological restoration is crucial in controlling invasion to improve biotic ...resistance and avoid further land degradation. We investigated the possibility of controlling the establishment of invasive alien species (IAS) by native seed addition. We tested if trait similarity or increased propagule pressure of native species results in the suppression of IAS at the early stage of development. We set up a sowing experiment with three widespread IAS in Hungary of different life forms and functional groups (Asclepias syriaca, Conyza canadensis, Tragus racemosus) and four Pannonic sand grassland species (Festuca vaginata, Galium verum, Gypsophila paniculata, Saponaria officinalis). We found no significant differences in germination ability and seedling emergence between native species and IAS, despite the differences in thousand‐seed weight. Using univariate general linear models, we found that the seedling establishment of IAS can be reduced by adding native species at high densities but also depending on the species identity. Instead of species of similar traits, the seeding of a competitor perennial grass of sand grasslands (F. vaginata) reduced the seedling emergence of all studied IAS the most. Our results confirm that IAS can be effectively controlled by native seed addition in the early establishment stage, especially applying higher densities and competitive species. We conclude that invasion‐resistant restoration can be achieved by the combination of several factors, including high‐density sowing of native species that match IAS in the early stage of development.
A resilience-oriented service restoration method using microgrids to restore critical load after natural disasters is proposed in this paper. Considering the scarcity of power generation resources, ...the concept of continuous operating time (COT) is introduced to determine the availability of microgrids for critical load restoration and to assess the service time. Uncertainties induced by intermittent energy sources and load are also taken into account. The critical load restoration problem is modeled as a chance-constrained stochastic program. A Markov chain-based operation model is designed to describe the stochastic energy variations within microgrids, based on which the COT is assessed. A two-stage heuristic is developed for the critical load restoration problem. First, a strategy table containing the information of all feasible restoration paths is established. Then the critical load restoration strategy is obtained by solving a linear integer program. Numerical simulations are performed on the IEEE 123-node feeder system under several scenarios to demonstrate the effectiveness of the proposed method. The impacts of fault locations, available generation resources, and load priority on the restoration strategy are discussed.
