Called NHS Forest, to date the programme has planted over 33,000 trees on 125 sites.
Related research shows strong links to improved community health where the public has access to green space and woodlands.
People are more likely to be physically active, with obvious benefits, where such access exists, while a University of Glasgow study found that premature death rates were also lower. This aspect of trees and woodland is becoming increasingly accepted in western countries as another non-wood benefit of forestry.
In other parts of the world it has long been regarded as an essential component of daily life.
In East Asia - notably China, Japan and Korea - the concept of 'forest bathing' and 'breathing the forest atmosphere' has been valued for centuries in preventing illness and aiding recovery.
Similar practices also have currency in Germany where Kneipp Therapy, which is broadly similar to the Asian concepts, has been practiced for about 150 years.
More recently, the Swiss authorities have started to advocate exercise specifically in forests, rather than in the gym or urban open spaces.
This has become so important that the major health insurance companies there now consider it a form of preventative medicine.
Since time immemorial, of course, indigenous peoples have lived in and with forests all over the world.
They have made medicines from trees and other plants and many communities consider certain trees to be sacred because of the numerous benefits, they provide.
Aboriginal peoples have always believed that everything is connected, that forests and the people are intimately linked.
Moreover they recognise the problems that occur when the link is broken and people are forcibly displaced from their land and forests.
Research is now taking place at the University of British Columbia in Canada, where the Department of Forestry and the School of Population and Public Health have joined forces.
Dr John Innes, Dean of Forestry at UBC, believes that considerable areas of woodland should be managed specifically to improve the physical and mental health of local populations.
Dr Innes cites three theories linking mental health to the natural environment:
•Biophilia - this theory maintains that we have been programmed during the course of evolution to respond positively to natural environments to help us survive and thrive, and where we feel more content and function more effectively;
• Attention Restoration Theory - this holds that the natural environment provides a restorative environment where our brains can 'recharge' when we're tired;
• Psycho-physiological Stress Recovery Theory - this is based on evidence that humans show an immediate positive response to views of nature.
This response causes a rapid reduction in stress levels, blood pressure, muscle tension and heart rate, usually within minutes of the exposure.
While little actual research on this aspect of forestry has been conducted in Ireland, COFORD actively promotes the concept as an integral part of the multi-use view of forestry.
Forest recreation in Ireland is an important part of the overall industry, with visitor numbers to Coillte forests close to 18m per annum, an average 4.5 visits per head of population.
The total economic activity generated by domestic forest users is estimated at €268m, which is over 10pc of the sector's total output.
Further Canadian research has found that the use of visual wood in buildings has a positive effect on health.
Dr David Fell of FP Innovations, a Canadian forest sector research institute, believes that exposure to wood in the built environment is a natural extension of the proven benefits of exposure to forests.
Dr Fell argues that as a species we have not yet adapted successfully to urban living. The results from his research indicate that where wood is a visible component of the built environment, there is a measurable reduction in stress.
It's clear that woodland may well contribute to a longer, healthier and happier life. There are many factors that inform the decision whether or not to plant, but surely this is one that deserves to be high on the list.
