Diverse, Ecoservicing, Resilient Urban Tree Trifecta Aid Dense Cities


Summary: Diverse, ecoservicing, resilient urban tree trifecta aid dense cities, according to an article in the November 2023 Arboriculture & Urban Forestry.


The University of British Columbia abides on Point Grey in Vancouver, Canada. The city abounds with the highest population density of all Canadian municipalities, according to the 2021 Census of 5,750 people per square kilometer; Bird's-Eye View of Ground Plan of University of British Columbia campus at Point Grey, designed 1912-1914 by English-Canadian architects George Lister Thornton (G.L.T.) Sharp (March 3, 1880-July 2, 1974) and Charles Joseph Thompson (Sep. 13, 1878-April 14, 1961)of Sharp and Thompson (founded 1908 and closed as Thompson, Berwick Pratt & Partners June 30, 1990) and winner of international competition in 1914: Public Domain, via Wikimedia Commons

Diverse, ecoservicing, resilient urban tree trifecta aid dense cities, per Sara Barron, Emily Rugel, Zhaohua Cheng, Lorien Nesbitt, Stephen Sheppard, Agatha Czekajlo and Cynthia Girling in November 2023’s Arboriculture & Urban Forestry.
The article Achieving the Urban Tree Trifecta: Scenario Modelling for Salubrious, Resilient, and Diverse Urban Forests in Densifying Cities broadcasts mental and physical health-benefitting urban forests. United Kingdom’s Greater Manchester green-roofing, increasing street trees 30% and vegetating impervious surfaces cut surface temperatures 3 to 4.9 degrees Celsius (37.4 to 40.82 degrees Fahrenheit). Building-energy efficiency and lower-emissions cycling-, public transit-, walking-transportation urban-densifying mitigation strategies decrease per-capita greenhouse-gas emissions even as they deny pervious surfaces, soil volume and urban greenspaces.
Direct, short-term climate change-effected building foundation- and road-impeding root proliferation, soil compaction and soil-toxifying heavy-metal deposits exacerbate urban-densified air-polluting wildfires, crown dieback-engendering heatwaves and nutrient-endangering flooding.

The article Achieving the Urban Tree Trifecta: Scenario Modelling for Salubrious, Resilient, and Diverse Urban Forests in Densifying Cities acclaims the common fig (Ficus carica) as most suitable species for projected climate change in British Columbia in general, Vancouver in particular; Saturday, June 22, 2019, 08:17, graphic of classification, origin, illustrations and distribution of Ficus carica (English common name: common fig; Spanish common name: higuera): MartínRománMangas, CC0 1.0 Universal Public Domain Dedication, via Wikimedia Commons

Future-friendly urban-forest management features blue-green streets with flood- and water quality-managing hydrologies and park-like vegetation of age-, size-, species-diverse, changing, projected climate-flexible, private- and public-planted trees.
Seven co-authors in Vancouver, Canada, at the University of British Columbia, guard 16 400-meter (1,312.34-foot) by 400-meter urban blocks from 1,600-meter (5,249.344-foot) by 1,600-meter proxy-area sandbox. Respectively 75, 4, 6, 1, 1 and 8% of the 15,164-resident parcel area in 2020 housed single-family homes, multi-unit dwellings, commercial properties, mixed-use, civic and greenspace/parks. The current-study, Scenario 4 of four modeling scenarios importantizes diverse, ecoservicing, resilient urban tree trifecta as maximally 30% one family, 20% one genus, 10% one species.
Baseline, private- and public-overplanted Acer and Prunus tree species jeopardize diverse, ecoservicing, resilient urban tree trifecta such that neither species joins the final Scenario-4 planting list.

An article co-authored by Sara Barron, Emily Rugel, Zhaohua Cheng, Lorien Nesbitt, Stephen Sheppard, Agatha Czekajlo and Cynthia Girling of Vancouver, Canada, at the University of British Columbia, acknowledges honey locust (Gleditsia triacanthos) as second-most suitable species for projected climate change in their province in general, in their city in particular; Friday, June 21, 2019, 11:19, graphic of classification, origin, illustrations and distribution of Gleditsia triacanthos (English common name: honey locust; Spanish common name: Acacia de tres espinas, Acacia de tres puntas, Acacia de tres púas): MartínRománMangas, CC0 1.0 Universal Public Domain Dedication, via Wikimedia Commons

Mature-only tree heights kept on online plant databases kindle 30-year canopy-spread and diameter estimates at 45% of small (under-10-meter/under-32.81-foot), medium and large (15-plus-meter/49.21-plus-foot) average mature-tree heights.
Private-planted trees launch diversely, ecoservicingly, resiliently even as 6.6% 2020 and 15.6% 2050 sandbox-total canopies respectively log 74% and 43% public and 26% and 57% private. Fifteen-plus-meter/49.21-plus-foot, tall trees maintain 25% and, decreasingly, 15% of baseline 2020 and Scenario-4 2050 canopies even as climate-adaptablest, medium-sized trees manifest most representatively in 2050 canopy. Case-study Scenario-4, 6.6% canopy doubled to 15.6% nudging temperatures downward and shade upward nurses health-benefits maximums, private- and public-planted urban forests and species navigating climate change.
Urban tree trifecta organize baseline-dominant top-8 Rosaceae, Betulaceae, Sapindaceae, Cupressaceae, Oleaceae, Pinaceae, Fabaceae, Moraceae families into Scenario-4 top-8 Pinaceae, Fabaceae, Rosaceae, Fagaceae, Sapindaceae, Cupressaceae, Anacardiaceae, Comaceae.

An article in the November 2023 issue of Arboriculture & Urban Forestry accounts common ash (Fraxinus excelsior) as third-most suitable species for projected climate change in southwesternmost Canada in general; illustration of leaves, fruits, flowers and general appearance of Fraxinus excelsior (English common name: common ash; French common name: frêne élevé): Lisa Nicvert (Pylea), CC BY SA 4.0 International, via Wikimedia Commons

That trifecta place as baseline-dominant top-8 Acer, Carpinus, Fraxinus, Thuja, Ficus, Liquidamber, Gleditsia, Pseudotsuga genera and Scenario-4 top-8 Koelreutaria, Maackia, Notholithocarpus, Quercus, Cercis, Crataegus, Pistacia, Prunus.
Acer, Gleditsia, Prunus and Sorbus baseline 2020 versus Scenario-4 2050 genera respectively queue 13 versus 1.9, 2.5 versus 1.8, 29.2 versus 4.4 and 1.9 versus 4.2%. Baseline 2020, unlike Scenario-4 2050, realizes Carpinus, Cedrus, Ficus, Fraxinus, Liquidambar, Parrotia, Pyrus, Pseudotsuga and Thuja species, with only Cedrus, Ficus, Fraxinus and Pinus shifting climate-resilient. Scenario-4 2050 realizes Abies, Catalpa, Cercis, Crataegus, Eucommia, Ginkgo, Gymnocladus, Juniperus, Koelreuteria, Maackia, Notholithocarpus, Nyssa, Pinus, Pistacia, Quercus species, with only Cercis and Pinus shifting climate-resilient.
Diverse, ecoservicing, resilient urban tree trifecta trigger dense cities campaigning educationally, private- and public-partnering shifting climate-resilient Cercis, Cedrus, Cupressus, Ficus, Fraxinus, Gleditsia, Pinus, Pyrus, Sorbus plantings.

An article on diverse, ecoservicing, resilient urban forests for the November 2023 issue of Arboriculture & Urban Forestry achieves a competition by whitebeam tree (Sorbus aria, synonymous with Aria edulis and Aria undulata) with Callery pear (Pyrus calleryana) for fourth-most suitable species for projected climate change in the University of British Columbia area of southwest Canada; J.C.
