Challenges and strategies in meeting urban tree canopy targets: A scenario discovery analysis to guide urban forest planning in new developments

Trees, Forests and People
With increasing urban populations worldwide, new developments face ambitious tree canopy cover targets to mitigate urban heat, reduce stormwater runoff, support biodiversity, and promote health benefits.

How tree species identity and diversity affect light transmittance to the understory in mature temperate forests [PDF]

, 2017
Light is a key resource for plant growth and is of particular importance in forest ecosystems, because of the strong vertical structure leading to successive light interception from canopy to forest floor.

Using Visible and Thermal Images by an Unmanned Aerial Vehicle to Monitor the Plant Water Status, Canopy Growth and Yield of Olive Trees (cvs. Frantoio and Leccino) under Different Irrigation Regimes

Agronomy, 2022
An efficient management of water relies on the correct estimation of tree water requirements and the accurate monitoring of tree water status and canopy growth. This study aims to test the suitability of visible and thermal images acquired by an unmanned

Canopy Structural Changes Following Widespread Mortality of Canopy Dominant Trees [PDF]

Forests, 2013
Canopy structure affects forest function by determining light availability and distribution. Many forests throughout the upper Great Lakes region are dominated by mature, even-aged, early successional aspen and birch, which comprise 35%–40% of canopy leaf area, and which are senescing at accelerating rates.

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

Advanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Tree leaf trade‐offs are stronger for sub‐canopy trees: leaf traits reveal little about growth rates in canopy trees [PDF]

Ecological Applications, 2018
AbstractCan morphological plant functional traits predict demographic rates (e.g., growth) within plant communities as diverse as tropical forests? This is one of the most important next‐step questions in trait‐based ecology and particularly for global reforestation efforts.

The Montado agroforestry system microclimatic specificity in the context of global change [PDF]

, 2009
The effects of oak trees on microclimatic parameters in Quercus rotundifolia Lam. woodland in the Alentejo, Southern Portugal, are reported. Results show that oak tree create a marked differentiation in the grass matrix, between open and undercanopy ...

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms

Advanced Robotics Research, EarlyView.
A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Health impact assessment of Philadelphia's 2025 tree canopy cover goals

The Lancet Planetary Health, 2020
Summary: Background: Cities across the world are undertaking ambitious projects to expand tree canopy by increasing the number of trees planted throughout public and private spaces. In epidemiological studies, greenspaces in urban environments have been
