Ethylenediurea (EDU) is a synthetic chemical known to protect plants from the phytotoxic effects of tropospheric ozone (O3). Although many studies have proposed the use of EDU for studying the O3 effects under field conditions, its mechanism of action is not fully understood, and it is unclear whether it exerts a specific antiozonant action, or if it may also interact with other oxidative stresses.
Target 2 of the European Biodiversity Strategy promotes the maintenance and enhancement of ecosystem services <(ES) as well as the restoration of at least 15% of degraded ecosystems by creating green infrastructure (GI). The purpose of the this research is to present a GI proposal that combines the delivery of regulating services with the restoration and ecological reconnection of urban forests and trees in a densely urbanised context.
UAV-based LiDAR survey provides very-high-density point clouds, which involve very rich information about forest detailed structure, allowing for detection of individual trees, as well as demanding high computational load. Single-tree detection is of great interest for forest management and ecology purposes, and the task is relatively well solved for forests made of single or largely dominant species, and trees having a very evident pointed shape in the upper part of the canopy (in particular conifers).
