“…This is based on the expectation that natural regeneration of native species will not occur without human intervention. While other buried-seed-bank studies have found that non-native species dominate the seed bank in urban areas (Overdyck and Clarkson, 2012;Hahs and McDonnell, 2013;Londe et al, 2017), we found this to only be the case for vacant lots in our study. Rather, large parks in our study were comprised of over 85% native speciesa result that is more consistent with findings from buried-seedbank studies in temperate rural forests rather than urban ones (Ashton et al, 1998;Leckie et al, 2000).…”

“…Our smallest patch size, vacant lots, consistently represented the earliest successional stage and most degraded habitat in terms of species composition. Seed bank analyses for the vacant lots in our study corroborate results from other urban seed bank studies being non‐native dominated (Overdyck and Clarkson, 2012; Hahs and McDonnell, 2013; Londe, et al, 2017). The abundance of non‐native species may be attributed to relatively higher edge‐to‐interior ratios in vacant lots as compared with large parks.…”

“…Vacant lots in our study were also similar to other urban buried‐seed‐bank studies in being dominated by herbaceous species (Pellissier et al, 2008; Overdyck and Clarkson, 2012; Londe et al, 2017). The abundance of herbaceous germinants suggests an earlier successional stage and has implication for restoration projects aimed at establishing forest cover as these herbs could slow forest succession by competing with tree species.…”

Questions: As urban areas expand around the world, understanding how to restore and maintain forests within the urban environment becomes increasingly important. Given that a comprehensive understanding of regeneration dynamics is critical to designating appropriate management interventions we ask the following: how does regeneration, vis-à-vis the buried seed bank, vary in heterogenous urban forests? And, can forest patch size be used to predict regeneration and consequent management interventions? Location: Vacant lots and public parks throughout New Haven, CT, USA. Methods: We sampled buried seed banks in 131 plots distributed across three forest patch sizes ranging from large intact parks (95-126 ha), to small parks (1-19 ha), and vacant lots (0.05-0.65 ha). We collected soil samples from the surface mineral soil and stratified them over sand in a greenhouse over a period of five months to record germination. Results: By examining seed bank floristics in a range of forest patch sizes we found that species composition, nativity, and dominance of specific functional groups shifted with patch size representing a spectrum of urbanization within just one city. Seed bank floristics in large parks more closely resembled results from seed bank studies in rural forests with over 85% native germinants on average. In contrast, vacant lots were dominated by non-native germinants and more ruderal species indicative of earlier successional stages. Seed banks in small parks were variable and in some cases were more similar to large parks or vacant lots. Conclusions: Our findings suggest that large parks in urban areas may be largely selfsustaining whereas smaller parks may require more intensive management for site rehabilitation, especially in early states of succession. Furthermore, our results confirm the highly heterogenous nature of urban forest patches and call for more systematic sampling of urban areas to capture this variation and improve management prescriptions and outcomes.

“…This issue is particularly relevant for the MAR areas as the exotic grasses from the adjacent UNR areas can spread toward them. Attention should be paid to exotic and invasive species because they can compromise ecosystem functions in restoration areas (Londe et al, 2017).…”

Ecological restoration has the potential to improve and recover soil quality, helping to mitigate soil degradation worldwide. However, soil monitoring is often overlooked in restoration, preventing a comprehensive understanding of how restoration interventions affect soil quality and the time required for recovering different soil properties. Herein, we tested if MAR areas (moderately assisted recovery—tree plantings) in the early restoration stage have better soil quality (and ecosystem services) than UNR areas (unassisted natural recovery—abandoned pastures) and pastures in continuous use (PCU). We collected 72 soil samples in three 5‐year‐old MAR areas and three 5‐year‐old UNR areas, one PCU, and one reference ecosystem (RE) in the Brazilian Atlantic Forest (Mata Atlantica). A total of 45 variables representing macrofauna, fertility, structure, and aggregation were measured and then submitted to multivariate analyses to compute sub‐indicators and a general indicator of soil quality (GISQ). The richness of orders and classes, cationic exchange capacity, total porosity, and biogenic aggregates contributed the most to the sub‐indicators. MAR and UNR areas had similar values to the RE for macrofauna, structure, and aggregation sub‐indicators, but they were far below the RE for fertility. In addition, all areas had lower GISQ values than the RE. Soils were classified as high quality in RE and medium quality in other areas. Our study evidences that some soils' physical and biological properties can be rapidly recovered through forest restoration, but 5 years is not enough time to change the general soil quality and make restoration areas have better conditions than the previous land use. If the restoration goal is to have high soil quality in the short term, corrective actions should be taken to improve soil fertility and help the area along the desired trajectory.

“…In this way, our findings reiterate the importance of the presence of conserved remnants that actively contribute with native seeds to areas under restoration. For comparison, a 5-year-old rehabilitated riparian forest in a neighboring municipality (Sabará), but far from forest remnants, had very low species richness in the seed rain and half of them were exotic (Londe et al, 2017).…”

We used seed rain to monitor a conserved forest and a 5-6-year-old forest undergoing natural regeneration after fire. The sampled species were classified according to regionality, life forms, dispersal modes, and successional stage, and the forests were compared. The type of forest and time since disturbance had significant effect on the abundance of seeds -67.3% being produced in the forest under restoration. Biological diversity was higher in the conserved forest. On the other hand, species richness was not affected by the type of forest, and the species composition was similar between forests. In addition, we found similar proportions of life forms, zoochorous species, and non-pioneer species in the forests. Our study shows that natural regenerating forests can recover different attributes of the seed rain in few years when in forest matrices. Thus, to accelerate restoration and create trustworthy forests we should conserve the remaining mature fragments and use them to facilitate ecological restoration.
