Variations in urban forest allergy potential among cities and land uses

Highlights Natural forests composition can have a substantial impact on pollen allergenicity in cities. Cities developed within Pinaceae forests tend to have lower allergenic potential. Forests/open spaces had slightly higher allergenic potential than developed areas. On average, less than 10 % of city leaf area is within the lowest allergenic class. Abstract Tree pollen with allergenic potential

Porous-permeable pavements promote growth and establishment and modify root depth distribution of Platanus × acerifolia (Aiton) Willd. in simulated urban tree pits

In dense urban areas with heavy pedestrian traffic, current trends favor covering tree pits with porous-permeable pavement over installing grates or leaving the soil exposed…

Urban tree growth and their dependency on infiltration rates in structural soil and structural cells

Expanding tree canopies can be difficult to achieve in built environments because urban land is costly and urban soil inhospitable to vegetation so engineered planting systems offer a potentially valuable tool for achieving sustainable urban forests. Tree water uptake, performance and root distribution were assessed in systems of structural soil and structural cell…
