Most of the described solutions center around tree planting. They are just the most effective way to cool cities.

Hundreds of communities around the country will share more than $1 billion in federal money to help them plant and maintain trees under a federal program that is intended to reduce extreme heat, benefit health and improve access to nature.

U.S. Department of Agriculture Secretary Tom Vilsack will announce the $1.13 billion in funding for 385 projects at an event Thursday morning in Cedar Rapids, Iowa. The tree plantings efforts will be focused on marginalized areas in all 50 states as well as Washington, D.C., Puerto Rico, the Virgin Islands and some tribal nations.

“We believe we can create more resilient communities in terms of the impacts of climate,” Vilsack told reporters in previewing his announcement. “We think we can mitigate extreme heat incidents and events in many of the cities.”

It was badly damaged in the fires and many thought the tree might not recover.

Hello fellow tree huggers,

Question: if I have a plot of land in the Western Washington Cascades, should I plant redwoods and/or sequoias on it on not? I would do this in addition to the obvious douglas firs, western red cedars, western hemlocks and various appropriate ground shrubs/ferns.

I can see a lot of articles about "assisted migration", many of which reference redwoods, but also all of which state that the idea is controversial. The idea is that Northern California is becoming less habitable for these trees, and Washington and BC become more like how California used to be, so the redwood forest will naturally migrate northwards. However, climate change is happening too fast for a slow-moving forest to realistically keep up.

The proponents argue that it's a way to preserve an important species, especially one which is a great carbon sink.

The doubters argue that some species of plants wouldn't survive the process, or could bring pests, or at least be susceptible them.

I can't tell if those drawbacks really pertain to redwoods/sequoias in Washington though. There are hundreds of them around the Seattle area that are doing just fine, more than a hundred years after residents planted them.

What do y'all think? Do it or no?

Neighborhoods with more trees and green space stay cooler, while those coated with layers of asphalt swelter. Lower-income neighborhoods tend to be hottest, a city report found, and they have the least tree canopy.

The same is true in cities across the country, where poor and minority neighborhoods disproportionately suffer the consequences of rising temperatures. Research shows the temperatures in a single city, from Portland, Oregon, to Baltimore, can vary by up to 20 degrees. For a resident in a leafy suburb, a steamy summer day may feel uncomfortable. But for their friend a few neighborhoods over, it’s more than uncomfortable — it’s dangerous.

The benefits of urban greening initiatives are increasingly well documented: they can help mitigate the effects of urban heating, and improve physical health and mental wellbeing. And even small greening actions in cities can significantly improve local biodiversity, new research suggests.

Increasing the diversity of native plants in a single urban green space resulted in a sevenfold increase in the number of insect species after three years, Australian researchers have found.

With value measured in cows, we would struggle to make a living from Thiaki even though rainforest was among the most biologically valuable pieces of land in the country.

The nearest town is Malanda, 15km to the north by road. While it hadn't been easy to turn lush tropical rainforest into paddocks - some individual settlers worked at it for decades - how could you turn paddocks back into rainforest? Local efforts on the Atherton Tablelands to restore degraded land back to rainforest were heroic but ad hoc.

Work commenced apace to design the reforestation research plan for the foundations of a brand-new rainforest that uses different mixes and numbers of native species with different planting densities.

On 28 January 2011, a bunch of academics and a crack team of planters with dirt under their fingernails and dreadlocks like flowing lianas, assembled to build the foundations of a rainforest with 30,000 plants, and to create the conditions for a phoenix to rise once more from the ashes.

The clearing frenzy of the first 20 years of the 20th century brought about the near extinction of the upland rainforest on the Atherton Tablelands.

• Reforestation success can be improved by enhancing tree planting methods
• Low sapling survival rates lead to high replacement costs and can hinder reforestation efforts
• Damage to fibrous roots during handling affects sapling survival
• Initial soil properties and conditions have a greater impact on sapling survival than adult traits
• Careful planting methods result in better sapling survival rates in the longer term
• Factors such as seedling survival, root growth, and seedling quality play a significant role in tree establishment
• Non-native grass removal and shade increase soil moisture and seedling performance during forest restoration
