Ecosystem Accounts – Forests and Woodlands 2012-2022

Extent Accounts

Forests & Woodlands extended to 769.6 thousand hectares in 2021, representing around 11% of the area covered by terrestrial and transitional ecosystems in Ireland. This was an increase of more than 5% (41.1 thousand hectares) on the 728.5 thousand hectares of Forests & Woodlands in 2012. Not all types of Forests & Woodlands increased at the same rate, however, and while the area of Coniferous forests increased by around 2% between 2012 and 2021, the area of Broadleaved forests increased by nearly 17%, and the area of Mixed forests increased by 16%. In 2021, our Forests & Woodlands comprised around 16% (122.4 thousand hectares) Broadleaved forests, just over 76% (588.1 thousand hectares) Coniferous forests, more than 5% (41.8 thousand hectares) Mixed forests, and just over 2% (17.3 thousand hectares) Transitional forests. Figure 2.1, Table 2.1.

The types of forests in Ireland have been strongly influenced by successive afforestation policies. In 1928 Ireland had just 98,000 hectares of Forests & Woodlands, around 1% of the national land area (National Forest Inventory 2022). Most of the increase in Forests & Woodlands since then has been down to afforestation through state sponsored or EU funded afforestation, although natural regeneration also plays a part. See Background Notes for more information on the different types of forests in this release.

The distribution of Ireland's Forests & Woodlands, and the change in distribution from 2012 to 2021, can be seen in Maps 2.1 and 2.2. Coniferous forests are clearly the dominant forest type. Due to the size of the forest patches, it is not easy to see exactly where each type of forest occurs. This will be examined in more detail in the next section.

 

 

Extent of Forests & Woodlands by County

Louth and Dublin were the counties with the lowest total coverage of Forests & Woodlands in 2021 at 3.4 and 3.7 thousand hectares, while Cork had the highest total area, at 90.3 thousand hectares. Table 2.2, Figure 2.2.

Meath, Dublin, and Louth were the counties with the lowest coverage of Forests & Woodlands as a percentage of the total county area in 2021, at 3.7%, 4%, and 4.2% respectively. Wicklow was the county with the highest coverage, at more than 20% of the total area of the county, followed by Leitrim (17.6%) and Waterford (15.8%). Table 2.2, Map 2.3, Figure 2.3.

Cork had the largest total area of Forests & Woodlands in 2021, and the largest total area of Broadleaved (13 thousand hectares), Coniferous (68 thousand hectares), and Mixed (4.4 thousand hectares) forests. As a proportion of the total area of Forest & Woodlands, Meath had the highest percentage coverage of Broadleaved forests (41%), followed by Louth (39.4%) and Kildare (32.3%). Mayo (87.7%), Donegal (87%) and Sligo (85%) had the highest percentage of Coniferous forests. The highest percentage coverage of Mixed forests occurred in Meath (14.1%), Kildare (12.9%) and Westmeath (11.3%). Dublin and Galway had the highest percentage coverage of Transitional forests at 2.8%. Figure 2.5, Map 2.4, Table 2.3.
