Thursday Trees – Preamble

A tree is considered to be a large, perennial, woody plant with secondary branches supported by a primary trunk. Most authors consider a tree species as being one which regularly reaches 6 m (20 ft) tall.

A native tree is considered to be one which is present in the region in question today, and has been continuously present in that region since a certain period of time. In the case of Ireland, this is generally taken as being a species that colonised the island during the retreat of ice at the end of the last ice age.

As such, native Irish trees include :

Alder, Crab Apple, Ash, Birch (Silver and Downy), Blackthorn, Cherry (Common and Bird), Elm (Wych), Hawthorn, Hazel, Holly, Juniper, Oak (Sessile and Pedunculate), Poplar (Aspen), Rowan (Mountain Ash), Scots Pine, Strawberry Tree, Whitebeam, Willow (Bay, Eared, Goat and Grey) and Yew.

Well established and well known non-native species, like the Horse Chestnut, Beech and Sycamore, are believed by most to be native also.

Each Thursday, I will endeavour to introduce one of these tress, with photos where possible.
