Thoughtful Reforestation

Forest

Forests make for naturally wonderful carbon sinks and thanks to a myriad of efforts we should see reforestation efforts grow over the next few years. This is all good to witness and we can all help by planting a tree. There are ways to tend to a forest for maximum carbon capture which scientists are hoping to perfect. It’s one thing to have a forest and it’s an even better thing to have a resilient high-quality forest which attracts a diversity of animals.

There are a number of ways that we can ensure new forests are resilient to these impacts. First, having a diversity of species with a wide variety of traits in the forest landscape reduces the risk that a single event will wipe out large parts of the ecosystem. This is because tree species have different resistances and vulnerabilities.

For example, pests and diseases are likely to migrate as the climate changes. In a single-species plantation, that could wipe out the whole forest. But with many different species in the area, parts of the forest will be resilient.

We should also plant and introduce species that are adapted to the future climatic conditions projected for the area. For example, if climate models project a drier climate with increased droughts, then including native species with tolerance to drought would increase the chances of that forest staying resilient, and therefore maintaining its carbon store for longer.

Ethiopia Planted 350 Million Trees in One Day

Forest

Earlier this year a group of scientists released a report that planting 1 trillion trees will essentially undo a decade of human carbon output. Ethiopia is doing its part by planting 350 million trees in just one year. The country is experiencing direct harms from the climate crisis (from deforestation to wildlife loss) and as chosen to plant trees to address those harms. They hope to ultimately plant 4 billion trees by the end of there rainy season!

Monday’s challenge had encouraged citizens in Africa’s second most populous nation to plant 200 million trees in one day. In 2017, India set the world record when around 1.5 million volunteers planted 66 million in 12 hours.
Ethiopia’s goal for the whole season is even bigger than that; the national tree planting campaign aims to plant 4 billion trees during “the rainy season” — between May and October — according to a May tweet by Ahmed.

Iceland Recovering from Deforestation

Long ago, when the vikings first arrived in Iceland the land was forested. Something between 25-40% of the country was covered by trees and humans slowly cut down the trees to an extent that was harmful to local ecosystems. Efforts to replant trees in the country have failed since they brought seeds from outside the country and a warming planet hasn’t been friendly to those trees. Now they are using native species to grow their forests and it’s working.

1.2 Trillion Trees can Balance a Decade of CO2 Emissions

Forest

The anti-conservation “conservative” Ontario government recently announced they cancelled a program that helped plant 28 million trees. The goal of that program was to plant 50 million trees to reduce flooding (which parts of Ontario are currently suffering from), clean the air, and protect wildlife. Fortunately there are smarter governments outside of Ontario that realize we need trees to breath and live.

A study by ETH Zurich has revealed that if we plant 1.2 trillion trees we can essentially cancel out a decade of anthropogenic carbon emissions. That might sound like a lot of trees but we do have space for them and can easily reach that goal, as long as governments that care about people are voted in. You can act locally and plant a tree in your yard (if you have one).

There is enough room in the world’s existing parks, forests, and abandoned land to plant 1.2 trillion additional trees, which would have the CO2 storage capacity to cancel out a decade of carbon dioxide emissions, according to a new analysis by ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university.

The research, presented at this year’s American Association for the Advancement of Science conference in Washington, D.C., argues that planting additional trees is one of the most effective ways to reduce greenhouse gases.

Reviving the “Dinosaur of Trees”

lab

Giant redwood trees are beautiful to look at and are great for the environment. We need them now more than ever before. The redwoods filter air, water while also removing tons of carbon due to their sheer size. These trees are so precious that scientists are trying to revive an ancestor of the modern redwoods.

Using saplings made from the basal sprouts of these super trees to plant new groves in temperate countries around the world means the growths have a better chance than most to become giants themselves. Their ancestors grew up to 400 ft (122 m) tall and to 35 ft in diameter, after all, larger than the largest living redwood today, a giant sequoia in California’s Sequoia National Park.
Already, super saplings from the project are thriving in groves in Canada, England, Wales, France, New Zealand, and Australia. None of these locales are places where coastal redwoods grow naturally, but they all have cool temperatures and sufficient fog for the redwoods, which drink moisture from the air in summer rather than relying on rain. Milarch calls this “assisted migration.”
