Database outcomes systematic review on participatory restoration ecology scenarios
<p><span>Large-scale ecological </span>restoration is <span>crucial for effective </span>biodiversity conservation <span>and combating climate change. However, perspectives on the goals and values of restoration are highly diverse, as are the different approaches to restoration e.g., ranging from the restoration of cultural ecosystems to rewilding. We assess how the future of nature is envisioned in participatory scenarios, focusing on which elements of rewilding and nature contributions to people have been considered in scenario narratives across Europe. We use the Nature Futures Framework to study how different perspectives on the the relationship of people with nature are captured in participatory scenarios. We found that a range of material, regulating and non-materical benefits were well represented in participatory scenarios. The different ecological aspects of rewilding were also present in many participatory scenarios, but not as well represented as nature contributions to people. Nature as culture was the main perspective present in the scenarios, with expected highest positive impacts on non-material benefits and to a lessesr extent on regulating benefits. Nature for nature futures were associated with positive impacts on regulating benefits and negative impacts on material benefits, being the only type of future associate with positive impacts on all three components of rewilding. Nature for society futures were associated with moderate positive impacts on all three types of nature contributions to people. Business as usual futures were associate with negative impacts on regulating and non-material benefits and on all three components of rewilding. Our</span> results <span>also </span>highlight<span> two major gaps that should be addressed in participatory restoration planning and models. Firstly, there is a paucity of spatially explicit approaches, with most studies failing to transform the results of participatory scenario planning into model projections. Secondly, we found scenarios that explored co-benefits between multiple nature perspectives were overall missing from the literature.</span></p>
Place re-making and sense of place after quarrying and social-ecological restoration - dataset
<p>The dataset provides coded input data for the study "Place re-making and sense of place after quarrying and social-ecological restoration". In this study, we examine how people’s place making and sense of place are reconfigured through quarrying. We investigate perceptions of sense of place after quarrying and social-ecological restoration in a limestone region of the Czech Karst in the Czech Republic. The dataset contains the result of our survey of 400 participants - visitors to the PLA Czech Karst who visited one of the eight study quarries and were questioned in the quarry. When selecting participants for our study, purposive sampling was applied to receive a gender-balanced sample of participants of various ages. We used a paper questionnaire suitable for the data collection directly in the field. The questionnaire was anonymous. </p>

Canopy cover and ecological restoration increase natural regeneration of rainforest trees in the Western Ghats, India
<p>Restoration of canopy cover through tree planting can assist in overcoming barriers to natural regeneration and catalyze recovery of degraded tropical forests. India has made international pledges to restore millions of hectares of degraded forests by 2030, but lacks empirical research on regeneration under different types of planted and natural overstories to guide this mission. We conducted a field study (65 plots of 25 m<sup>2</sup>) to examine the influence of overstory type and canopy cover on naturally regenerating tree seedlings across degraded rainforests (DR), mixed-native species ecological restoration sites (ER), monoculture eucalypt plantations (MP), and mature "benchmark" rainforests (BR) in the Western Ghats mountains of peninsular India. ER had higher native tree seedling densities and recovered community composition towards BR levels compared to DR, while communities in MP shifted in the opposite direction. Densities of native late-successional species increased with canopy cover (particularly in ER), but greater canopy cover was also associated with increases in alien species, a few of which are shade-tolerant. Further, in a nursery experiment comprising four rainforest species, seed germination and early survival increased with shade, but did not vary across soils originating from DR, ER, and MP. Our findings show that while improving canopy cover is important, doing so by planting diverse native species, and controlling invasive alien species, can benefit rainforest recovery in degraded rainforest fragments. Conversely, planting non-native monocultures in degraded forests, which is a prevalent practice in India, could prove counterproductive for forest recovery in the long term.</p>
Using genomics to guide seed-sourcing at the right taxonomical level for ecological restoration projects: the complex case of Carex bigelowii s.lat. in Norway
<p>There is a growing demand for ecological restoration using suitable seeds following international standards or national legal demands for local seed-sourcing. However, before selecting the appropriate geographic origin of seeds, it is vital to explore taxonomic complexity related to the focal taxa. We used ddRAD-seq to screen genomic diversity within <i>Carex bigelowii</i> s.lat. focussing on Norway. This species complex is considered a candidate for seeding, but presents considerable morphological, ecological, and genetic variation. The genetic structure of 132 individuals of <i>C</i>. <i>bigelowii</i> s.lat., including <i>C</i>. <i>nigra</i> as an outgroup, was explored using ordinations, clustering analyses, and a genetic barrier algorithm. Two highly divergent clusters were evident, supporting the recognition of two taxonomic units '<i>C</i>. <i>dacica</i>' and 'subsp. <i>bigelowii</i>'. Previously defined seed-sourcing regions for <i>C</i>. <i>bigelowii</i> s.lat. did not consider the known taxonomic complexity, and therefore interpreted the overall genetic structure as seed-sourcing regions, not taxa. We estimated genetic neighbourhood sizes within each taxon to be 100-150 km and 300 km, respectively, indicating species-specific delimitations of local seed-sourcing regions. Frequent hybrids, local genetic distinctiveness, and suggested ecotypes add complexity to the discussed seed-sourcing regions. Our results show how genomic screening of diversity and structure in a species complex can alleviate the taxonomic impediment, inform practical questions and legal requirements related to seed-sourcing, and together with traditional taxonomic work provide necessary information for a sound management of biodiversity.</p>
Impacts of ecological restoration on the genetic diversity of plant species: A global meta-analysis
<p>1. In contrast to the depth of knowledge available for the enhancement of plant species diversity and ecosystem services through ecological restoration, our understanding of how ecological restoration impacts genetic diversity (GD) of plant species has not yet been synthesized.</p> <p>2. We performed a global meta-analysis to examine whether ecological restoration improved GD of plant species in restored populations. First, we compared the GD of restored populations with reference or degraded populations. Second, we explored whether the influence of ecological restoration on plant GD varies between species with different characteristics (life form and threat status), between different restoration strategies (active/passive, seeding/planting, mixture/non-mixture) or between different restoration times (<50 and ≥50 years; with an average of 29.3 years).</p> <p>3. The GD of restored populations was significantly lower (HE, 1.06%; PPB, 5.10%, and SWI, 4.95%) than in reference populations but was comparable to degraded populations. The inbreeding coefficient (FIS, the proportion by which the heterozygosity of an individual is reduced by inbreeding) was consistently comparable between restored populations and reference or degraded populations.</p> <p>4. Woody species but not herbs had significantly lower GD in restored populations than in reference populations. Forest but not grassland ecosystem had significantly lower GD in restored populations than in reference populations. Passive but not active restoration, seeding rather than planting, and mixing materials from different sources rather than using a single source, all significantly increased the GD of restored populations. When the restoration time was ≥50 years, in contrast to <50 years, GD was comparable between the restored and reference populations.</p> <p>5. Synthesis and applications. In general, ecological restoration did not significantly improve the GD of plant species compared to reference or degraded populations. This might be due in part to the relatively short restoration time. Using passive restoration, seeding, and mixed sources could significantly increase the GD of restored populations. We emphasize that GD should not be treated as a minor cobenefit of ecological restoration for other purposes and that the recovery of GD should be listed as a vital goal in future ecological restoration with plant species.</p>
Gene prediction for: A reference genome for ecological restoration of the sunflower sea star, Pycnopodia helianthoides
<div> <div> <div> <div>Wildlife diseases, such as the sea star wasting (SSW) epizootic that outbroke in the mid-2010s, appear to be associated with acute and/or chronic abiotic environmental change; dissociating the effects of different drivers can be difficult. The sunflower sea star,<em> Pycnopodia helianthoides</em>, was the species most severely impacted during the SSW outbreak, which overlapped with periods of anomalous atmospheric and oceanographic conditions, and there is not yet a consensus on the cause(s). Genomic data may reveal underlying molecular signatures that implicate a subset of factors and, thus, clarify past events while also setting the scene for effective restoration efforts. To advance this goal, we used Pacific Biosciences HiFi long sequencing reads and Dovetail Omni-C proximity reads to generate a highly contiguous genome assembly that was then annotated using RNA-seq-informed gene prediction. The genome assembly is 484 Mb long, with contig N50 of 1.9 Mb, scaffold N50 of 21.8 Mb, BUSCO completeness score 96.1%, and 22 major scaffolds consistent with prior evidence that sea star genomes comprise 22 autosomes. These statistics generally fall between those of other recently assembled chromosome-scale assemblies for two species in the distantly related asteroid genus <em>Pisaster</em>. These novel genomic resources for <em>Pycnopodia helianthoides</em> will underwrite population genomic, comparative genomic, and phylogenomic analyses — as well as their integration across scales — of SSW and environmental stressors. This data resource contains the files associated with gene prediction.</div> </div> </div> </div>

Data for L.R. Johnson and S.N. Handel - Restoration treatments in urban park forests drive long-term changes in vegetation trajectories - Ecological Applications doi:10.1890/14-2063.1
Initial data from long-term research plots in New York City Park forest patches invaded by exotic woody plant species. Half (n = 30) of the sites were restored 15-20 years prior to first sampling in 2009-2010. The same suite of invasive plants was recorded in the other half of the sites at the time of initial restoration in the late 1980s and early 1990s (n = 30), but they were not restored in 2009-2010.
Data from: Changes in soil microbial communities in post mine ecological restoration: implications for monitoring using high throughput DNA sequencing
<p>The ecological restoration of ecosystem services and biodiversity is a key intervention used to reverse the impacts of anthropogenic activities such as mining. Assessment of the performance of restoration against completion criteria relies on biodiversity monitoring. However, monitoring usually overlooks soil microbial communities (SMC), despite increased awareness of their pivotal role in many ecological functions. Recent advances in cost, scalability and technology has led to DNA sequencing being considered as a cost-effective biological monitoring tool, particularly for otherwise difficult to survey groups such as microbes. However, such approaches for monitoring complex restoration sites such as post-mined landscapes have not yet been tested. Here we examine bacterial and fungal communities across chronosequences of mine site restoration at three locations in Western Australia to determine if there are consistent changes in SMC diversity, community composition and functional capacity. Although we detected directional changes in community composition indicative of microbial recovery, these were inconsistent between locations and microbial taxa (bacteria or fungi). Assessing functional diversity provided greater understanding of changes in site conditions and microbial recovery than could be determined through assessment of community composition alone. These results demonstrate that <span>high-throughput amplicon sequencing of environmental DNA (eDNA)</span> is an effective approach for monitoring the complex changes in SMC following restoration. Future monitoring of mine site restoration using eDNA should consider archiving samples to provide improved understanding of changes in communities over time. Expansion to include other biological groups (e.g. soil fauna) and substrates would also provide a more holistic understanding of biodiversity recovery. </p>
Data from: Does origin always matter? Evaluating the influence of nonlocal seed provenances for ecological restoration purposes in a widespread and outcrossing plant species
For restoration purposes, nature conservation generally enforces the use of local seed material based on the "local-is-best" (LIB) approach. However, in some cases recommendations to refrain from this approach have been made. Here we test if a common widespread species with no obvious signs of local adaptation may be a candidate species for abandoning LIB during restoration. Using 10 microsatellite markers we compared population genetic patterns of the generalist species Daucus carota in indigenous and formerly restored sites (nonlocal seed provenances). Gene diversity overall ranged between He = 0.67 and 0.86 and showed no significant differences between the two groups. Hierarchical AMOVA and principal component analysis revealed very high genetic population admixture and negligible differentiation between indigenous and restored sites (FCT = 0.002). Moreover, differentiation between groups was caused by only one outlier population, where inbreeding effects are presumed. We therefore conclude that the introduction of nonlocal seed provenances in the course of landscape restoration did not jeopardize regional species persistence by contributing to inbreeding or outbreeding depressions, or any measurable adverse population genetic effect. On the basis of these results, we see no obvious objections to the current practice to use the 10-fold cheaper, nonlocal seed material of D. carota for restoration projects.
Data from: A global meta-analysis on the ecological drivers of forest restoration success
Two billion ha have been identified globally for forest restoration. Our meta-analysis encompassing 221 study landscapes worldwide reveals forest restoration enhances biodiversity by 15–84% and vegetation structure by 36–77%, compared with degraded ecosystems. For the first time, we identify the main ecological drivers of forest restoration success (defined as a return to a reference condition, that is, old-growth forest) at both the local and landscape scale. These are as follows: the time elapsed since restoration began, disturbance type and landscape context. The time elapsed since restoration began strongly drives restoration success in secondary forests, but not in selectively logged forests (which are more ecologically similar to reference systems). Landscape restoration will be most successful when previous disturbance is less intensive and habitat is less fragmented in the landscape. Restoration does not result in full recovery of biodiversity and vegetation structure, but can complement old-growth forests if there is sufficient time for ecological succession.
