Temperature accelerates the rate fields become forests

Secondary succession, the postdisturbance transition of herbaceous to woody-dominated ecosystems, occurs faster at lower latitudes with important ramifications for ecosystem processes. This pattern could be driven by the direct effect of temperature on tree growth; however, an alternative mechanism is tree–herb competition, which may be more intense in more fertile northern soils. We manipulated soil fertility and herbaceous species composition in identical experiments at six sites spanning the Eastern United States (30–43° N) and monitored the growth and survival of four early successional trees. Tree seedling mass 2 years after sowing was strongly associated with site differences in mean growing season temperature, regardless of species or soil treatment. The effect of temperature was twofold: seedlings grew faster in response to warmer site temperatures, but also due to the reduction of competitive interference from the herbaceous community, which was inhibited in warmer sites. Our results suggest that increasing temperatures will promote a faster transition of fields to forests in temperate ecosystems.

Contrasting ecological roles of non-native ungulates in a novel ecosystem

Conservation has long focused on preserving or restoring pristine ecosystems. However, understanding and managing novel ecosystems has grown in importance as they outnumber pristine ecosystems worldwide. While non-native species may be neutral or detrimental in pristine ecosystems, it is possible that even notorious invaders could play beneficial or mixed roles in novel ecosystems. We examined the effects of two long-established non-native species—Philippine deer (Rusa marianna) and feral pigs (Sus scrofa)—in Guam, Micronesia, where native vertebrate frugivores are functionally absent leaving forests devoid of seed dispersers. We compared the roles of deer and pigs on seedling survival, seed dispersal and plant community structure in limestone karst forests. Deer, even at low abundances, had pronounced negative impacts on forest communities by decreasing seedling and vine abundance. By contrast, pigs showed no such relationship. Also, many viable seeds were found in pig scats, whereas few were found in deer scats, suggesting that pigs, but not deer, provide an ecosystem function—seed dispersal—that has been lost from Guam. Our study presents a discrepancy between the roles of two non-native species that are traditionally managed as a single entity, suggesting that ecological function, rather than identity as a non-native, may be more important to consider in managing novel systems.

Where and why does restoration happen? Ecological and sociopolitical influences on stream restoration in coastal California

The distribution of conservation effort on the landscape is affected by both ecological and social priorities and constraints. Together these influences can result in bias towards certain types of ecological or human communities. The authors evaluate the distribution of restoration projects on the California Central Coast, USA, to evaluate sociopolitical and biophysical influences on the type and distribution of one type of conservation effort. They compiled data on 699 sites with publicly funded stream restoration and management projects completed in the past 30 years and the biophysical and sociopolitical characteristics of the 310 sub-catchments in the study area. Their database contains three categories of stream projects: ecological restoration to benefit natural ecosystems, human-oriented projects to enhance ecosystem services, and data collection projects for planning and monitoring. Both ecological and human-oriented restoration efforts were clustered near the coastline. Stream activities of all kinds were highest in sub-catchments with water quality impairment, high population density, high pro-environmental voting, and a highly educated, wealthy, non-Hispanic white population. Ecological restoration and data collection were also greater in catchments with higher native fish richness. Our findings indicate that restoration activity is aligned with, and perhaps responding to, ecological need, and that restoration efforts are concentrated near human population centers and restoration organizations. Disparities in conservation effort by income, race, and education are concerning and should be evaluated in more depth and in other regions.

Fire management in the Brazilian savanna: First steps and the way forward

Several decades of frustrated attempts to prevent fires in the Brazilian Savanna (Cerrado) have led to deleterious ecological and management consequences. In 2014, the first Integrated Fire Management (IFM) programme was launched in three protected areas (PAs). The IFM programme considers local practices, ecological information, management options and aims to create landscape mosaics of different fire histories to conserve biodiversity, reduce the prevalence of late‐dry season (LDS) wildfires, protect fire‐sensitive vegetation and reduce conflicts between PA managers and local communities. The first 3 years of imposed fire management regimes led to 40%–57% reduction in LDS fires, improved dialogue between researchers, managers and local communities, generating fire management learning communities. This Integrated Fire Management programme represents a major advance in Cerrado management and conservation, by actively managing fires and decreasing the proportion of areas burnt by late‐dry season wildfires. It can contribute to PAs’ management in the Cerrado and other South American fire‐prone ecosystems. Long‐term monitoring and research are essential to understand the ecological implications and to improve fire management practices.

Effects of national ecological restoration projects on carbon sequestration in China from 2001 to 2010

China has launched six key ecological restoration projects since the late 1970s, but the contribution of these projects to terrestrial C sequestration remains unknown. In this study the authors examined the ecosystem C sink in the project area (∼16% of the country’s land area) and evaluated the project-induced C sequestration. The total annual C sink in the project area between 2001 and 2010 was estimated to be 132 Tg C per y, over half of which (74 Tg C per y, 56%) was caused by the implementation of the six projects. This finding indicates that the implementation of the ecological restoration projects in China has significantly increased ecosystem C sequestration across the country.

The ecology and economics of restoration: when, what, where, and how to restore ecosystems

Restoration ecology has provided a suite of tools for accelerating the recovery of ecosystems damaged by drivers of global change. The authors review both the ecological and economic concepts developed in restoration ecology, and offer guidance on when, what, where, and how to restore ecosystems. For when to restore, they highlight the value of pursuing restoration early to prevent ecosystems from crossing tipping points and evaluating whether unassisted natural recovery is more cost-effective than active restoration. For what to restore, they encourage developing a restoration plan with stakeholders that will restore structural, compositional, and functional endpoints, and whose goal is a more resistant and resilient ecosystem. For where to restore, they emphasize developing restoration approaches that can address the impediment of rural poverty in the developing world and identifying and then balancing the ecosystems and regions in most need of restoration and those that are best positioned for restoration success.

The Role of Networks Connecting Native Seed Stakeholders

Connecting stakeholders and facilitating the transfer of knowledge is crucial to improve success in ecological restoration. Like the nodes of the ecological networks we aim to restore, those who work with native seeds are connected and dependent on each other for information and resources to address the challenges of seed conservation, research, production and use. Presented by INSR’s Marcello de Vitis.

Peatland Restoration

50 % of the original peatland area of Finland has been drained for forestry. This had an immense degrading impact on the natural values of mires. Peatland restoration has been found as an effective way to regain these values. More than 25 000 hectares of different types of peatlands has been restored since the beginning of the 1990´s. In restoration the mire must become more permanently waterlogged again. This is best achieved by completely filling in ditches and by removing trees. The results of restoration are evaluated by different monitoring methods.

ROOT – A decision-support tool

Presented by Craig Beatty of LERS and IUCN. Following over three years of development through a partnership between International Union for Conservation of Nature (IUCN) and The Natural Capital Project, ROOT (Restoration Opportunities Optimization Tool) is a software tool that optimises trade-offs among different ecosystem services to help decision-makers visualise where investments in restoration could be made that would optimise benefits for multiple landscape goals.

Technically, ROOT applies an integrated linear programming algorithm which optimises and displays the location of the expected ecosystem services generated through restoration. Most notably, it does so for multiple ecosystem services at the same time and can weigh these optimisations based on the location of people who rely on such services. This includes optimising landscape restoration interventions in areas that would generate clean water, or avoiding areas where disadvantaged people might be negatively affected by changes or modifications in land use. The result is knowledge that is not purely biophysical, but instead blends the social priorities of those with the rights to manage land with the ecosystem service benefits that are expected from restoration.

This webinar will explore why ROOT was designed, how it works, and a few case studies showing the different results that it can generate and the implication of those results in national and international large-scale restoration programmes and policies.

Spatial decision-support tools to guide restoration and seed-sourcing in the Desert Southwest

Altered disturbance regimes and shifting climates have increased the need for large‐scale restoration treatments across the western United States. Seed‐sourcing remains a considerable challenge for revegetation efforts, particularly on public lands where policy favors the use of native, locally sourced plant material to avoid maladaptation. An important area of emphasis for public agencies has been the development of spatial tools to guide selection of genetically appropriate seed. When genetic information is not available, current seed transfer guidelines stipulate use of climate‐based or provisional seed transfer zones, which serve as a proxy for local adaptation by representing climate gradients to which plants are commonly adapted. Despite this guidance, little emphasis has been placed on identifying best practices for deriving provisional seed zones or on incorporating predictions from future climate. We describe a flexible, multivariate procedure for deriving such zones that incorporates a broad range of climatic characteristics while accounting for covariation among climate variables. With this approach, we derive provisional seed zones for four regions in the Desert Southwest (the Mojave Desert, Sonoran Desert, Colorado Plateau, and Southern Great Basin). To facilitate future‐resilient restoration designs, we project each zone into its relative position in the future climate based on near‐term, RCP4.5 and RCP8.5 emissions scenarios. Although provisional seed zones are useful in a variety of contexts, there are also situations in which site‐specific guidance is preferable. To meet this need, we implement Climate Distance Mapper, an interactive decision‐support tool designed to help practitioners match seed sources with restoration sites through an accessible online interface. The application allows users to rank the suitability of seed sources anywhere on the landscape based on multivariate climate distances. Users can perform calculations for either the current or future climates. Additionally, tools are available to guide sample effort in regional‐scale seed collections or to partition the landscape into climate clusters representing suitable planting sites for different seed sources. Our tools and analytic procedures represent a flexible and reproducible framework for advancing native plant development programs in the Desert Southwest and beyond.

Raising the standard in restoration after mining

Presented by Kingsley Dixon, chair of SER Australasia and Director of the Australian Research Council’s Centre for Mine Site Restoration.

Mining is a global enterprise and combined with oil and gas, occur from the Arctic to Australia and beyond. Since the earliest mining from before the Romans, mining has impacted landscapes, affected livelihoods and is often at odds with traditional land utilisation. Though much of the mining industry globally aspires to high standards of environmental care, few are actively engaged in the process of restoration of sites to a standard that reflect the need to repatriate landscapes and ecosystems that reflect the local environment. In this webinar I will present a snap shot of global impacts, global success stories, emerging technologies for the industry and the role of the International Standards for the Practice of Ecological Restoration in driving higher and better outcomes in the global resources sector.

Coastal Zone Management Trust, Quintana Roo, Mexico

This green infrastructure finance mechanism is an innovative financial framework that provides a tool for mobilizing resources to implement restoration. The Nature Conservancy (TNC) designed and will test this first-ever mechanism that leverages the protective service of reefs and secures that ecosystem service with an insurance policy and funding structure. In partnership with the State Government of Quintana Roo, academic institutions, and the tourism and insurance industries, the project lays the groundwork for vulnerable coastal communities to strengthen both physical and financial resilience against climate change. This pilot project will support tourism and local communities by funding reef and beach protection and restoration after severe storms.

Species Recovery Manual

Species recovery involves many different disciplines and actors, and responsibility for it at a national level is often unclear, given that it cuts across different ministries and agencies. After various consultations, it was felt by BGCI and IABG that it would be valuable to produce a manual that would clarify the aims and purpose of species recovery, set out the various steps involved, and indicate good practice. This manual is aimed specifically at conservation practitioners but also includes comprehensive bibliographic references, which enable more in depth reading on the topics covered in this publication. The manual includes chapters and case studies from members of the Ecological Restoration Alliance of Botanic Gardens.

The contributing authors uncover a vast network of interested citizens and volunteer groups committed to preserving the region’s environment. The book also pinpoints emerging issues of importance in the Midwest, such as climate change and the increase in invasive species it is expected to bring to the region.

Oregon Invasive Species Council – A Comprehensive Review of the State Strategy

Invasive species are nonnative organisms that can cause devastating economic and environmental harm. In Oregon, a diversity of organizations across the state are focusing efforts on preventing the establishment of new invasive species and taking actions to eradicate, control, and/or manage the invasive species that have already arrived. In order to conduct a comprehensive and coordinated effort to prevent, detect, control, and eliminate invasive species, the Oregon Legislature established the Oregon Invasive Species Council (OISC) in 2001.

The OISC is comprised of members from state and public agencies, tribes, scientists, educators, and members of the public who lead Oregon’s fight against invasive species and protect Oregon’s natural resources and economy from the harm that invasive species cause. After a collaborative process of input and engagement of many colleagues across the state working to protect Oregon from invasive species, the Council adopted the Statewide Strategic Plan and Action Plan for Invasive Species in 2016, which lays out the long-term and short-term strategies for invasive species control in Oregon. Among the strategies, ecosystem recovery and resilience are prioritized as essential to long-term protection of Oregon’s resources and environments. This holistic approach is necessary for our state to be successful in its battle against invasive species.

Jalene Littlejohn is co-founder and director of Samara Group, an Oregon-based consulting firm that was created to enhance environmental projects. Jalene is the Lead Coordinator for the Oregon Invasive Species Council (OISC) and supports a number of other invasive species and conservation initiatives in the region. She has been involved with the SERNW Chapter since 2015 and continues to support the upcoming SER-SWS Joint Regional Conference.

Rory presents his extensive works involving the restoration of urban landscapes for the purpose of establishing pollinator habitats.

Biodiversity guidelines for forest landscape restoration opportunities assessments

These guidelines are intended to provide more context, more resources and fresh perspectives to the ongoing global interaction between biodiversity conservation and forest landscape restoration. They do so in the context of the Restoration Opportunities Assessment Methodology (ROAM), which is being used by dozens of countries and jurisdictions to help practitioners working on identifying and realizing their landscape restoration goals — and they should be interpreted as a companion to ROAM.

Landscapes, at your service

The Restoration Opportunities Optimization Tool (ROOT) was developed out of a need to more efficiently and effectively communicate the importance of ecosystem services to decision makers. IUCN’s collective experience working to increase ecological productivity and improve human well-being through forest landscape restoration (FLR) demonstrated that although stakeholders were interested in generating ecosystem services from proposed restoration activities, the many services and their interactions with each other were often too complicated to communicate clearly. Furthermore, as a social process, decision makers working towards restoration were interested in more than just the biophysical gains from restoration for different services; they wanted evidence for how restoration might benefit agricultural production, access to jobs or different sources of income, and how investments in restoration might help underserved or marginalized groups. The case studies in this report were chosen based on ongoing FLR assessments as well as the existence of ecosystem services data, and are intended to demonstrate the applicability of ROOT to both technical and non-technical audiences.

Spatially designed revegetation—why the spatial arrangement of plants should be as important to revegetation as they are to natural systems

The spatial arrangements of plants, both within and between species, play a key role in natural systems and influence many fundamental ecological processes (e.g. survival, competition, facilitation, pollination, and seed dispersal) and ecosystem functions (e.g. habitat value, erosion, water, and nutrient capture). Despite this knowledge, fine‐scale planting arrangements are rarely considered during restoration plantings, yet manipulation of planting designs has the potential to aid the development of resilient and self‐sustaining ecosystems. Here, the authors outline how the spatial arrangement of plants can influence processes both at the vegetation level and more broadly at the ecosystem level. The review is focused on woodland systems, but also draws on key examples from grassland ecosystems. Finally, they outline components of population and community level arrangements (e.g. spacing, aggregation, community composition) that can be considered during restoration plantings—spatially designed revegetation—which are likely to lead to improved ecological outcomes of woodland and grassy woodland revegetation.

Post-fire Restoration in the Great Basin – Challenges, Opportunities, and a Call to Make Adaptive Management Real

The vast sea of sagebrush-steppe rangelands that supported iconic wildlife and many ecosystem services has been heavily impacted by exotic plant invasions and altered wildfire, motivating one of the largest restoration and rehabilitation efforts globally. Members of the Great Basin Chapter of SER will describe the efforts, past and future, from scientific and management perspectives, and address the needs and prospects for an adaptive management approach.

The emergence of the social‐ecological restoration concept

Many ecosystems in the world are the result of a close interaction between local people and their environment, which are currently recognized as social‐ecological systems (SoES). Natural catastrophes or long‐standing social and political turmoil can degrade these SoES to a point where human societies are no longer autonomous and their supporting ecosystems are highly degraded. Here, the authors focus on the special case of the restoration of SoES termed social‐ecological restoration (SoER), which is characterized as a restoration process that cannot avoid simultaneously dealing with ecological and social issues. In practice, SoER is analogous in many ways to the general principles of ecological restoration, but it differs in three key aspects: (1) the first actions may be initially intended for human groups that need to recover minimum living standards; (2) the SoER process would often be part of a healing process for local people where cultural values of ecosystems play an essential role; and (3) there is a strong dependency on external economic inputs, as the people belonging to the SoES may be incapable of reorganizing themselves on their own and supporting ecosystems can no longer self‐recover.

Communicating useful results from restoration ecology research

Interactions between restoration ecologists and stakeholders (policy makers and decision makers, volunteers, public supporters) benefit from clear communication of research findings. Given that adaptive management (e.g. learning while restoring) already stresses frequent and effective discourse among researchers and stakeholders, it seems that a new specialty under a new term, “translational ecology,” adds more confusion than clarity. Communicating technical information to nontechnical audiences benefits from simple rules—be clear and concise, retain familiar terms that serve well, and use fewer words.
