Crown shapes of common European urban tree species differ from to and are modified by the age a its local environment. A tree’s crown shape has great influence on volume thus ecosystem service provision such as shade area or density. We used data 3852 individuals eight German cities 528 trees for Acer platanoides, pseudoplatanus, Aesculus hippocastanum, Fraxinus excelsior, Platanus × acerifolia, Robinia pseudoacacia Tilia cordata analyze structural dimensions dependency shapes. Ovoid (57% all individuals) spherical (24%) were mostly observed. However, columnar was observed light-demanding R. in close proximity objects. The greatest areas measured highest density ovoid shape. Logistic regression analysis showed significant effects distance objects Significant probability found different species, e.g., A. hippocastanum strongly half-ellipsoid

Limiting climate warming to <2°C requires increased mitigation efforts, including land stewardship, whose potential in the United States is poorly understood. We quantified of natural solutions (NCS)—21 conservation, restoration, and improved management interventions on agricultural lands—to increase carbon storage avoid greenhouse gas emissions States. found a maximum 1.2 (0.9 1.6) Pg CO2e year−1, equivalent 21% current net annual At market prices (USD 10 per Mg CO2e), 299 Tg year−1 could be achieved. NCS would also provide air water filtration, flood control, soil health, wildlife habitat, resilience benefits.

Anthropogenic stress and disturbance of forest ecosystems (FES) has been increasing at all scales from local to global. In rapidly changing environments, in-situ terrestrial FES monitoring approaches have made tremendous progress but they are intensive often integrate subjective indicators for health (FH). Remote sensing (RS) bridges the gaps these limitations, by FH on different spatio-temporal scales, in a cost-effective, rapid, repetitive objective manner. this paper, we provide an overview definitions FH, discussing drivers, processes, adaptation mechanisms plants, how can observe with RS. We introduce concept spectral traits (ST) trait variations (STV) context discuss prospects, limitations constraints. Stress, disturbances resource cause changes taxonomic, structural functional diversity; examples ST/STV approach be used characteristics. show that RS based assessments using is competent, affordable, technique monitoring. Even though possibilities observing taxonomic diversity animal species limited RS, taxonomy tree recorded even its accuracy subject certain proved successful impacts diversity. particular, it proven very suitable recording short-term dynamics which cannot cost-effectively methods. This paper gives approach, whereas second series concentrates monitoring, sensors techniques measuring FH.

Abstract Population ageing and shrinking are demographic phenomena with far-reaching implications for sustainability in the current context of extensive rapid urbanization. This Perspective rationalizes their interface by (a) identifying challenges opportunities that urban populations will have implementing sustainable development goals (SDGs), (b) discussing some emerging interventions to capitalise on reduce achieving sustainability. We argue a diverse set context-specific technological, socioeconomic, institutional governance would be needed leverage effectively minimize risks posed long-term

• Urban tree canopy cover is a promising solution for mitigating heat island. Data-driven guidance on selection and planting locations still limited. Four research priorities are proposed, requiring collaborative effort. Cross-climate morphological physiological characteristics desired. Integration with atmospheric boundary layer models suggested.

The potential to capture additional air pollutants by introducing more vegetation or changing existing short woodland on first sight provides an attractive route for lowering urban pollution.

Light detection and ranging (LiDAR) technology has become one of the most dominant acquisition methods for modeling forest attributes, such as very accurate tree structure information, which is necessary qualitative management research activities. In this study, we evaluated efficacy standalone unmanned aerial vehicle-laser scanning (UAV-LS) terrestrial laser (TLS) data to accurately estimate metrics under differing types. Furthermore, combined UAV-LS TLS test whether fusion can improve mapping three-dimensional (3D) individual trees favor estimates metrics. We initially calculated percentage point density per square meter aboveground in each height class at intervals 1 m UAV-LS, TLS, datasets. This helped illustrate vertical distribution that reflects structural complexity between broadleaf conifer trees. then used tree-level clouds assess several metrics, diameter breast (DBH), total (HT), crown projection area (PAC), width (WC), length (LC), 3D surface (SC), volume (VC). Our results indicated LiDAR increase estimation accuracy DBH HT, especially broadleaves (97.8% accuracy). addition, significantly reshaped modeled structures both plots, led improved all The show empirical evidence also have a determining role supporting ecosystem services. For example, detailed crowns be mitigation rainfall`s kinetic energy by concerning soil erosion sedimentation near habitable zones.
