As urban forest provides ecological, social, and economic values to the residents, forest inventory can monitor forest health. Based on the land classification map, the campus planning team pays attention to tree health in the public green space of the University of British Columbia (UBC) campus in Vancouver, Canada. Working together, the forest inventory and land classification map are the priorities of urban planning and forest health in UBC. In order to solve the knowledge gap of no current inventory and land classification map on campus, this study aimed to update the UBC tree inventory and land classification map. R algorithms extracted individual trees’ parameters and metrics like tree height and crown area using Light Detection and Ranging (LiDAR) data 2018 by the City of Vancouver. The author applied random forest classification to determine the tree species (coniferous/deciduous) with the metrics. Four major land cover types were classified by the supervised classification scheme using the UBC orthophoto 2020. The results show that there are 14165 trees (crown diameter more than 4 m) on campus, and the height estimation by the LiDAR method had an overall accuracy of 80% comparing to the field data. The campus’s total vegetation cover was 44% that is higher than the cities in Great Vancouver. The land classification map shows that most of the vegetation cover is on the southern campus. Considering the campus’s topography, coniferous trees on the southwest campus provided potential ecological implications of water retention and preventing soil erosion. The study provided the basis for future studies of trees, vegetation, and UBC Vancouver Campus land planning.

These data represent detailed tree canopy in Vancouver, WA. Tree canopy was mapped by EarthDefine using machine learning techniques on 2019/2020 NAIP imagery. Tree canopy includes specific classifications for deciduous and evergreen trees.

In response to growing concerns about the impacts of climate change and the need for sustainable urban development, urban forests have emerged as a crucial tool for mitigating climate change impacts and enhancing the quality of life in cities. Previous studies have established that urban forests provide a wide range of ecosystem services, including air purification, temperature regulation, and carbon sequestration. However, precise estimation of urban tree carbon storage remains a key challenge for effective urban forest management and planning. In this work, we expand on this body of work by investigating the carbon storage of trees on the UBC Vancouver Campus using 2018 Light Detection and Ranging (LiDAR) data sourced from the City of Vancouver. The aim was to determine the total carbon storage and the average carbon density of the campus. Tree height and structure were estimated using an existing model, which facilitated the calculation of individual tree biomass and carbon storage based on the LiDAR data. The results revealed that the UBC Vancouver Campus has a total carbon storage of 24.63 Gg and an average carbon density of 6.13 kg m-2. These findings emphasize the significant role urban forests play in climate change mitigation and urban life improvement. Employing LiDAR data in conjunction with the existing model proved to be an efficient and effective method for estimating urban tree carbon storage. The results can inform urban planning and policy decisions, fostering the integration of urban forests into sustainable campus development.

AbstractThe triple threats of climate change, habitat loss, and environmental pollution have stimulated discussion on how urban areas can be modified to both mitigate heat increases and provide habitat for wildlife such as insects. The strategy of using trees to reduce temperatures has been adopted by numerous cities. However, the majority of street trees planted around the world are non-native. Studies conducted in non-urban areas have demonstrated in comparison to native plants, non-native plants are less likely to support native insect diversity. Here we use a database approach to quantify the number of native Lepidoptera species associated with 76 of the most common street tree species planted in Vancouver, Canada. We tested the prediction that compared to non-native trees, native street trees will support a higher diversity and unique community of native Lepidoptera. As predicted, native street trees were associated with five times as many native Lepidoptera species, and the Lepidoptera communities supported by native vs. non-native street trees were distinct. There was no difference in native Lepidoptera associations between broadleaf vs. coniferous street trees. These results are consistent with studies that have used active sampling techniques to investigate insect richness on a smaller subset of native and non-native tree species. Collectively, these data provide good evidence that the planting native instead of non-native trees will help stem the loss of insect diversity in urban areas. MethodsData were compiled from existing databases or published literature. No new data were collected.

Custom code accompanying the paper: 'Conifers may ameliorate urban heat waves better than broadleaf trees: evidence from Vancouver, Canada' by Harold N. Eyster and Brian Beckage, published in Atmosphere.

To manage future green spaces on campus and adopt to the changing climate, the Social Ecological Economic Development Studies (SEEDS) program of the University of British Columbia (UBC) organized a series of projects to predict the climate suitability (occurrence probability) of some common tree species existing at the UBC Vancouver campus by 2100. With a generally low climate suitability, coniferous trees are more vulnerable to the change of precipitation and temperature, and climate change is threatening the growth of coniferous trees in British Columbia, Canada. Western hemlock (Tsuga heterophylla) is a common coniferous tree species occurring at UBC Vancouver campus and was chosen to be analyzed in this study. The analysis of climate suitability was done using a MaxEnt model. As a machine-learning algorithm not requiring data about absent points, MaxEnt is considered to be a good tool for predicting the distribution of species. There were 19 bioclimatic variables tested in the analysis, and the precipitation in the coldest quarter of the year was determined to be the most important climatic variable affecting the growth of Western hemlock. The results showed that the occurrence probability of Western hemlock would drop from its current ~87% to ~10% under one of the most likely climate models in 2100. Although this result could not represent the real occurrence probability of Western hemlock by the end of the century due to the limited data and variables considered (climate only), this study provided a reference for future climate suitability analysis at UBC Vancouver campus of other tree species and could potentially help with the protection of existing Western hemlock at the campus.

New dating of lahar-killed trees underscores volcano hazards in the Puget Sound metropolitan area. Beginning as a landslide from the west flank of Mount Rainier, Washington, the Electron Mudflow swept more than 60 km down the Puyallup River drainage into areas now heavily populated. Wiggle-matching of seven radiocarbon ages from buried, bark-bearing Douglas-fir (Pseudotsuga menziesii) trees brackets the mudflow’s age between 1477–1522 CE with 99.7 percent certainty. The trees with bark all died the same year. Analysis of the Electron chronology using crossdating of tree rings best matched with chronologies from low-elevation sites, especially a Douglas-fir chronology from Vancouver Island, Canada, to show that the Electron trees died in 1507 CE. These data are in three tables, containing properties of the lahar-killed Douglas-fir included in the Electron tree-ring chronology (C14_S1.csv); radiocarbon data from trees killed in the Electron Mudflow (C14_S2.csv); and properties of lo ...

This extension note details a study on how adding nutrients affects the growth of young red alder trees on Vancouver Island. Recognizing the increasing importance of red alder for various products and ecological restoration, the research investigates whether fertilization, particularly with phosphorus and other elements, can enhance their early development. The document describes field trials conducted at multiple locations, outlining the experimental setup, fertilization treatments, and the resulting stem growth responses observed in the first year after application. The document aims to provide initial insights into optimizing the growth and quality of red alder through nutrient management in this region.

Pollination is an essential ecosystem service for crop production, where species such as insects and birds help to transfer pollen for plants to reproduce. Many of the pollinators are fully dependent on the plants and trees as their food sources and habitat. From a perspective of an urban planner, we must be able to recognize the values brought by pollinators to our ecosystems. Thus, we are attempting to discover the relationship between species and their habitats as much as possible. Nevertheless, assessing and quantifying habitat for species is a particular difficult task when we are dealing with a complex structured urban landscape. This study has two main objectives: the first one is to delineate and assess the biodiversity hotspots as pollinators habitat to determine which to prioritize for planting design management, and the second one is to determine the difference in tree crown delineation using Light Detection and Ranging (LiDAR) point cloud and Orthophoto interpretation. As a result, we found that each delineation method has different limitations and advantages. With the implementation of habitat overlay analysis, the mean patch size of biodiversity hotspots is around 2100 m^2, indicating that most green spaces in urban landscapes tend to be more fragmented rather than shrinking in size.
