#urbanforestry — Public Fediverse posts

🌳 Ah, the urban forest fairy tale where one heroic soul single-handedly turned a wasteland into a leafy paradise 🦸‍♀️. Meanwhile, the rest of us are still trying to keep a cactus alive in our apartments 🌵. Apparently, the secret to urban renewal is just wishing really hard and a sprinkle of magic park dust. ✨

Does urban greenery yield microclimatic cooling? Spatial analysis of Calgary (Summer 2025) shows a non-linear NDVI vs LST response.

🛠 Stack: Google Earth Engine (Landsat 8/9, Sentinel-2) + R (terra, tidyverse).

📊 Key Findings:
🔹 Cooling Deficit (NDVI < 0.34): LST stays trapped at 35–36°C. Heat stress overrides evapotranspiration; saplings & isolated lawns fail to cool.
🔹 Tipping Point (NDVI > 0.34): Cooling begins above 0.34. Dense canopy (NDVI > 0.70) suppresses LST below 28–30°C (6–8°C delta).

💡 Takeaway: Urban forestry can't just count saplings. Without threshold canopy density, isolated greenery is decoration, not climate infrastructure.

Which Calgary neighborhoods are best built to withstand summer heatwaves? 🌳☀️

To measure structural climate resilience across the city, I conducted a spatial analysis of 193 established residential communities, calculating the Solid-to-Tree Ratio—comparing bare artificial surfaces (asphalt, concrete, rooftops) directly against total tree canopy area.

Here are the Top 10 most shade-rich and climate-resilient communities in Calgary:
🟢 Queens Park Village — 0.3 (Just 0.3 ha of hard surface for every 1 ha of canopy!)
🟢 Discovery Ridge — 0.5
🟢 Roxboro — 0.5
🟢 Wildwood — 0.6
🟢 Rideau Park — 0.7
🟢 Medicine Hill — 0.8
🟢 Upper Mount Royal — 0.8
🟢 Crestmont — 0.9
🟢 Elbow Park — 0.9
🟢 Shaganappi — 0.9

🔥 Top 10 Calgary Communities with the Highest "Shade Deficit"

To measure structural heat risks, I calculated the Solid-to-Tree Ratio—the ratio of bare artificial surfaces (asphalt, concrete, roofs) to total tree canopy area. A higher ratio means more heat-retaining concrete and less natural cooling.

Here are the 10 most shade-deficient residential communities in Calgary:
🔹 Downtown Commercial Core — 56.2 (56.2 ha of hard surfaces for every 1 ha of trees)
🔹 Beltline — 24.6
🔹 Redstone — 23.8
🔹 Seton — 20.8
🔹 Manchester — 17.7
🔹 Rangeview — 16.8
🔹 Symons Valley Ranch — 16.0
🔹 Lower Mount Royal — 13.9
🔹 Country Hills Village — 13.2
🔹 Martindale — 12.4

A lot of people don't know this, but trees provide shade AND air conditioning ❄️

This doesn't mean plant them willy-nilly, but that a good, healthy tree in the right place has a *massive* positive benefit. Yay learning!

Took two days off work to attend an #UrbanForestry training. I can't express how healing it was to be around a large group of like-minded people. I feel completely reinvigorated. Plus, I'm looking forward to helping out with the canopy in my #urban #community.

People there definitely know what we are up against, but they brought joy and resolve the journey ahead. I'm really grateful for this community. #solarpunk #environment #resilience #trees #nature

🌳 I am finalizing a tool that allows for a rapid and accurate assessment of the green infrastructure in any Calgary community. This isn't just "green color" on a map—my algorithm recognizes the differences in the quality and structure of the urban environment.

What we can quantify right now:
🔹 Lawn (Grasses, low shrubs): Open spaces that tend to dry out and heat up quickly during summer.
🔹 Park (Sparse Canopy): Scattered groups of trees in parks and private yards.
🔹 Forest (Dense Canopy): The "lungs" of a neighborhood, characterized by closed canopies and thick undergrowth. These areas provide vital protection against urban heat.

❗ Why does this matter?
Using Inglewood as an example (see the chart), we can see that "dense forest" covers only about 5% of the area. This is a critical indicator of the territory's climate resilience.

Urban trees are more than just decoration—they reduce heat and improve air quality in our busy cities.

West Oakland is getting 1,500 new trees—but who will care for them? After decades of neglect due to cuts to city tree services, residents and local nonprofits are stepping in to fill the gap.

🌳🎰 Ah, the genius solution to Vegas's sizzling heat: more trees! Because nothing screams innovation like turning the desert into a forest. 🙄 Apparently, climate change is no match for a few saplings and a sprinkle of wishful thinking. 🌵🌞

Las Vegas is embracing a simple climate solution: More trees

The City of #Portland #UrbanForestry department sent me a request to confirm that we have planted a new tree to replace our Honey Locust that fell down in the ice storm last last winter.

How do I explain that the roots of the old tree are now growing 5 new trees like a bunch baby groots? Do you think they will accept them as a replacement?

New interview with NPR: "'Grants like this are part of the responsibility of the federal government to help communities advance their interest and their progress, right?' Keith also says research shows trees return more financially than what you pay for them." https://www.npr.org/2025/03/14/nx-s1-5310005/trump-administration-cuts-to-dei-even-affecting-nationwide-effort-to-plant-trees #urbanforestry

In 2001, a shock assessment revealed that two-thirds of all trees in Stockholm's city center were dead or dying.

The local authorities knew that a change was urgently needed to revive these essential urban ecosystems.

Dude. Urban Forestry job in Boston accepting applicants, salaried ($62k) and benefits, plant trees and talk about trees and learn about trees and tend trees. Trees!!!
