Global tree-planting campaigns can harm natural drylands. Effective climate restoration must work within dryland ecosystems, not seek to replace them.

The tree mix matters. Near Chesapeake Bay, scientists have been experimenting with mini-forests for over a decade. The surprising results show how biodiversity pays off.
In the first study of its kind, researchers matched more than 1,500 Sydney house sales with data on nearly 50,000 public trees. They found location is crucial.
Governments have pledged vast areas for new forests, but much of this land may be unsuitable.
Reforestation can contribute significantly to tackling climate change, but research found its global potential is only a fraction of what’s been claimed.
Cities are seeking low-cost ways to ease the heat island effect. Researchers found benefits and trade-offs in two popular options, but they vary by city and even neighborhood.
Planting trees might make Freetown in Sierra Leone more resilient to climate change but it won’t end global warming. Only ditching fossil fuels can do that.
Tree planting can help address the climate and biodiversity crises – but only in the right circumstances.
Interviews with tree experts reveal that while half of them supported the Miyawake method, especially in specific urban areas, concerns remained about tree mortality and high costs.
The Great Green Wall is great in theory but too complicated to achieve without more localised planning.
Nature can provide solutions to problems such as biodiversity loss and climate change. But the best nature-based solutions are resilient to disturbance such as fire or drought and future change.
Planting trees to remove carbon from the atmosphere will only be effective alongside other strategies to reduce greenhouse gas emissions.
Climate modelling that best accounts for the processes that sustain plant life predicts plants could absorb up to 20% more CO₂ than the simplest version predicted.
The idea that harm done today can be offset in the future is based on a basic misunderstanding of the carbon cycle. Planting more trees is important – but it’s no substitute for cutting emissions.
Many people are gardening on land that is not theirs – here are some things to consider to avoid getting into trouble.
Could community gardening emerge as an effective method for addressing climate anxiety?
Native trees have been found at new heights in the Scottish Highlands, demonstrating how mountain woodland could recover from deforestation – benefiting humans, wildlife and climate issues.
Funding decisions under the federal program were largely driven by simplistic considerations, such as the cost of each tree, rather than benefits to threatened species.
The rapidly changing climate presents many challenges for the sustainability of forest ecosystems. Assisting the migration of trees is a tool to address these challenges.
Australia has half as much forest as it did before colonisation. Restoring it can be hugely expensive. But new approaches can help
