Special Issue Information

Dear Colleagues,

Interest in a better understanding of the range of both the values and challenges that urban trees provide and experience continues its ascent, globally, and to derive benefits (e.g., esthetic/economic values, shade, carbon storage/sequestration, fruit crops, human health considerations, biodiversity, and wildlife habitat), trees must establish and mature in size. Urban trees face many difficult conditions that include construction pressures/injury, pests, and challenges related to climate change. Among each of these areas, important knowledge gaps remain.

For this Special Issue, we encourage submissions related to the formal exploration of these topics that include—but are not limited to—theoretical, empirical, and modeling investigations that employ quantitative, qualitative, and/or mixed methodologies related to the following:

  • Evaluation of the esthetic or economic contributions of trees;
  • Tree function and/or performance (growth, survival, mortality, and morbidity) assessment in densely populated settings;
  • Understanding of human health considerations and benefits related to trees;
  • Techniques related to protecting and utilizing trees, wood, and wood products in urban settings;
  • Assessment of factors that inhibit tree performance (pests, construction activities, climate change);
  • Applications of new or emerging technologies.

We hope that this Special Issue provides a forum for novel insights that will advance our understanding of urban trees and their affiliated benefits to people and the landscape around them.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The acquisition of plant ecological indicators, such as leaf area index and leaf area density values, typically relies on labor-intensive field sampling and measurements, which are often time-consuming and hinder large-scale application. As different plant ecological indicators are closely related to plants’ geometric characteristics, the development of dynamic correlation and prediction methods for relevant indicators has become an important research topic. However, existing 3D plant models are mainly used for visualization purposes, which cannot accurately reflect the plant’s growth process or geometric characteristics. This study presents a workflow for parametric 3D plant modeling and ecological indicator analysis, integrating dynamic plant modeling, indicator calculation, and microclimate simulation. With the established plant model, a method for calculating and analyzing ecological indicators, including the leaf area index, leaf area density, aboveground biomass, and aboveground carbon storage, was then proposed. A method for exporting the model-generated data into ENVI-met v.5.0 to simulate the microclimate environment was also established. Then, by taking Daijia Lake Park as an example, this study utilized site planting construction drawings and field survey data to perform parametric modeling of 21,685 on-site trees from 65 species at three different growth stages using Blender v.4.0 and The Grove plugin v.10. The generated plant model’s accuracy was then verified using the 3D IoU ratio between the models and on-site scanned point cloud data. Plant ecological indicators at various stages were then extracted and exported to ENVI-met for microclimate analysis. The workflow integrates the simulation of plant growth dynamics and their interactions with environmental factors. It can also be used for scenario-based predictions in planting design and serves as a basis for urban green space monitoring and management. Full article
