"We know trees help deal with carbon emissions and flooding, they help your well-being, there's very good evidence that being around trees reduces your stress and your blood pressure. There's evidence to show that areas with lots of trees have a lower crime rate." Wales Deputy climate change minister Lee Waters said.
Every household in Wales will be offered a free tree to plant in an effort to help tackle climate change.
People will have a choice of native species to plant in their gardens or have added to woodland on their behalf.
About 1.3 million trees will be made available by the Welsh government, in a scheme which will cost £2m. The trees will be available from five hubs from March, with a further 20 in the autumn of 2022.
