About the Trees...

One Million Trees in One Day focuses on native Irish broadleaf trees.  All of the trees are grown in Ireland and are of certified native seed provenance with exceptions noted below. 

We plant a mixture of individual trees, groups of trees, small woodlands, shelter belts, hedgerows, coppice groves, agroforestry projects, orchards and larger woodlands. We work with hundreds of farmers, smallholders, schools and colleges, community groups and other landowners to find land to accommodate trees each season.

We supply bare-rooted forestry grade whips; these young trees are hardy and well adapted to the Irish climate and, being small, can be planted and handled easily by almost anyone.

Common species and rarer species:

A number of the native Irish trees are commonly available and easy to source. These species are oak, common alder, common birch, hawthorn, blackthorn, hazel, mountain ash, and scot's pine.  The majority of our planting is therefore carried out with mixes of these species as appropriate to each site.  Luckily they are a diverse and hardy collection and they serve us well for establishing woodlands, copses, hedgerows and shelter belts in all sorts of conditions. 

The other species in the table above are more difficult and expensive to source.  We are working with nurseries across the island to encourage more growth of these native species from certified seed sources and hope to see them become more readily available over the coming seasons.

Non-Native Species:
Whilst almost all of the trees are native species, we have a few exceptions to the native rule.

Naturalised Species:
Beech, lime, chestnut, horse chestnut and others are considered by many to be naturalised in Ireland as they have been growing here for hundreds of years.  In some woodlands and in parkland surrounding large historical houses and castles, these species were planted as part of the original landscape designs.  We occasionally use Irish grown trees of these species where it is appropriate to the landscape. 

Fruit and Nut Trees:
Orchard establishment is very important to the project in trying to contribute diverse sustainable resources for the future.  We plant both traditional and heritage varieties of apples and other naturalised fruiting trees - pears, plums, cherries, damsons etc.  We occasionally use non-native and or imported trees for particular orchard projects where it is appropriate.

Shortages of Trees 2016: 
Between 2013 and 2015 we supplied only Irish grown trees.  This year 2016 we have struggled to source a diverse range of species to put into our hedgerow and woodland establishment projects.  We imported some additional trees from the UK to add into our planting packs.  We work closely with brilliant nurseries in Ireland and hope to be able to source a wider variety of species in future and continue using only Irish provenance and Irish grown trees.

Ash Die-back:
Due to the presence of the Ash Die-back disease in the UK and Ireland we will not be planting any ash for the project.  We will replace all ash trees to be planted with other species as appropriate to each site.
