“…In outlining a performance evaluation framework for urban GI development, Tiwary et al 120 suggest that a plant's tolerance of relevant environmental stresses should be given priority over all other functionalities as an indicator of its suitability. This point is supported by findings from numerous studies into aspects of successful plant establishment in urban areas, all of which support the principle that the viability of individual species varies with planting site conditions 41,68,123,[125][126][127] .…”

Vegetation can form a barrier between traffic emissions and adjacent areas, but the optimal configuration and plant composition of such green infrastructure (GI) are currently unclear. We examined the literature on aspects of GI that influence ambient air quality, with a particular focus on vegetation barriers in open-road environments. Findings were critically evaluated in order to identify principles for effective barrier design, and recommendations regarding plant selection were established with reference to relevant spatial scales. As an initial investigation into viable species for UK urban GI, we compiled data on 12 influential traits for 61 tree species, and created a supplementary plant selection framework. We found that if the scale of the intervention, the context and conditions of the site and the target air pollutant type are appreciated, the selection of plants that exhibit certain biophysical traits can enhance air pollution mitigation. For super-micrometre particles, advantageous leaf micromorphological traits include the presence of trichomes and ridges or grooves. Stomatal characteristics are more significant for sub-micrometre particle and gaseous pollutant uptake, although we found a comparative dearth of studies into such pollutants. Generally advantageous macromorphological traits include small leaf size and high leaf complexity, but optimal vegetation height, form and density depend on planting configuration with respect to the immediate physical environment. Biogenic volatile organic compound and pollen emissions can be minimised by appropriate species selection, although their significance varies with scale and context. While this review assembled evidence-based recommendations for practitioners, several important areas for future research were identified.

“…Forest gaps thus create important habitat for the regeneration of plant species, which may otherwise be suppressed by the undercanopy (Han et al 2011;Sharma et al 2018). They also play a vital role in forest regeneration and succession, especially in the establishment and development of plant species that differ in ecological recruitment (Runkle 1998;Han et al 2013;Mountford et al 2006;Zhu et al 2014;Jankovska et al 2015). It has been reported that canopy gaps close when the height of regenerations reached 20 m, consistent with the definition used by Nagel et al (2008).…”

BackgroundTree mortality and seedling and sapling recruitment are essential components of forest dynamics in arid regions, especially those with serious eco-hydrological problems. In recent decades, the mortality of the Euphrates poplar ( Populus euphratica ) along the Tarim River in Northwest China has increased. However, few studies have quantified the causes of mortality and regeneration in this azonal riparian forest type. MethodsThe present paper describes the annual hydrological response of tree mortality and regeneration in forest gaps. A total of 60 canopy gaps were investigated in six replicate grid plots (50 m × 50 m) and the annual runoff and water consumption data during the period of 1955–2016 were collected from hydrological stations along the middle reaches of the Tarim River. In addition, we compared the regeneration density of seedlings and saplings within the canopy gap areas (CGAs), undercanopy areas (UCAs), and uncovered riverbank areas (RBAs) through detailed field investigation. ResultsOur study found that the mortality of young and middle aged gap makers has increased markedly over recent decades, particularly since 1996. The main results indicated that regional water scarcity was the primary limiting factor for long-term changes in tree mortality, as shown by a significant correlation between the diameter at breast height (DBH) of dead trees and the annual surface water. The average density (or regeneration rate) of seedlings and saplings was highest in the RBAs, intermediate in the CGAs, and lowest in the UCAs. Compared with the UCAs, the CGAs promote tree regeneration to some extent by providing favorable conditions for the survival and growth of seedlings and saplings, which would otherwise be suppressed in the understory. Furthermore, although the density of seedlings and saplings in the CGAs was not as high as in the RBAs, the survival rate was higher in the CGAs than in the RBAs. ConclusionThis study shows that forest canopy gaps can play a decisive role in the long-term germination and regeneration of plant species. However, as a typical phreatophyte in this hyper-arid region, the ecosystem structure, functions and services of this fragile P. euphratica , floodplain forests are threatened by a continuous decrease of water resources, due to excessive water use for monocultural cotton irrigation, which has resulted in a severe reduction in intact poplar forests. Furthermore, the survival of seedlings and saplings is influenced by light availability and soil water at the regional scale. Our findings suggest that policymakers may need to reconsider the restoration and regeneration measures implemented in riparian P. euphratica forests to improve flood water efficiency and create canopy gaps. Our results provide valuable reference information for the conservation and sustainable development of floodplain forest ecosystems.

“…The introduction of features of recreational infrastructure is also an important issue. Studies [40,41] highlight the technical condition of recreational infrastructure as one of the most crucial factors influencing the development of tourism in forests. A different point of view is presented by the authors of studies whose results showed that tourists are more likely to indicate resting in forests without developed recreational infrastructure [42,43].…”

Manor parks are characteristic cultural features in Polish agricultural landscapes. About 10,000 manor parks are estimated to exist in Poland, and due to their high natural, historic and scenic value, these features represent potential in terms of ecosystem services. To properly manage these sites, it is advisable to determine the preferences of its visitors. The present study presents the results of a quantitative survey based on a group of 352 young visitors to manor parks in south Poland. The results show that visitors with higher monthly incomes have a statistically significant higher awareness as far as caring for the authenticity and preservation of the natural and historical heritage of manor parks and forests. Conversely, for visitors with lower incomes, additional touristic promotion attractions (e.g., souvenirs, guided visits) are increasingly important. The results of the study provide an important basis of information for local authorities, as well as private owners, with regard to preserving the natural and historical values (which are closely connected with the scenic values) of these sites, as well as local tourism development. The values of nature, sustainability, tourism and the improvement of life quality are linked to the enhancement of manor parks, as these facilities are providers of ecosystem services.
