The Woodland Trust (Coed Cadw) is launching a petition calling for all cities, towns and villages in Wales to have a minimum 20% tree canopy cover.
It also backs the planting of native trees which, it says, can provide a habitat and nectar source for pollinators and fruit trees which will provide a sustainable source of food.
It says the tree canopy cover in Wales varies dramatically, from just 4.5% in Fochriw in Caerphilly to 34% in Trimsaran in Carmarthenshire.
It also cites a study in Wrexham, last year, which, it says, showed trees save the local economy £1.3m every year by:
- Intercepting 27 million litres of rainfall from entering the drainage system, the equivalent of saving £460,000 in sewerage charges.
- Absorbing 1,329 tonnes of carbon dioxide from the atmosphere.
- Improving health by removing 60 tonnes of air pollution, saving the health services £700,000.
The Woodland Trust have unveiled plans to plant a new wood in Wales to mark the centenary of the Great War.
Four new woodlands will be planted across the UK. The project will cost around £12m and will see millions of trees planted.
More than three million free trees will given to schools, communities and youth groups. The project is intended to be a legacy to those who died, fought or lost loved ones between 1914 and 1918.
The site of Wales's centenary wood is still being discussed.
Forestry workers have begun to fell hundreds of acres of trees in the largest ancient woodland in Wales because they have been infected by a fungal disease.
It is spreading through thousands of larch trees that are growing in the historic Wentwood Forest between Newport and Chepstow.
Years of conservation work by the Woodland Trust will be undermined by the felling of trees at Wentwood Forest.
Restoration work the charity began in 2006, involving the gradual removal of conifers to allow native broadleaf trees and characteristic ancient woodland flora and fauna to return, will be destroyed.
Much of Wentwood Forest was planted with confiers in the 1940s and 50s as a means of providing fast-growing wood for building. This has led to the decline of many species and unique characteristics of ancient woodland. Larch trees are part of attempts to restore the forest to its natural state.
Wales' largest ancient forest is to have many of its trees felled due to a fungus-like disease. Hundreds of acres of Wentwood Forest near Newport will be cut down. It's thought that the disease will continue to spread in the coming months and further felling will be required.
Natural Resources Wales says it will spend £500,000 immediately to try to stop the Phytophthora ramorum tree disease from spreading further.
An extra £2 million will be provided for carrying out future work.
Trees in Wales' largest area of ancient woodland - Wentwood Forest near Newport - are being felled due to a devastating disease.
The Woodland Trust says larches in have been attacked by Phytophthora ramorum, which can damage and kill trees.
Work has already begun to remove 500 acres of the woodland.
The disease is already affecting thousands of larch trees elsewhere in Wales, the South West of England, Ireland and Scotland.
The Woodland Trust says tree planting figures in Wales were just 900 hectares, only 18% of what's needed to meet the Welsh Government’s own target.
The aim is to create 100,000 hectares of new woodland across Wales over a 20-year period.
The Trust also claims because of reform of the Common Agricultural Policy to be implemented from 2014, no new grants will be made available to landowners looking to plant trees in 2014.
The Woodland Trust fears planting rates in Wales will fall next year because of the reform.
A spokesperson for the Welsh Government says it'll respond later.
