Transcript Irish forests - Seomra Ranga

A project by 4th and 5th class
Silviculture
 Silviculture is the growing of trees
 The Irish State Forestry department is called Coillte

Teoranta
The word “coillte” means woodlands
70% of all iris forests are owned by Coillte.
Trees grow better in good soil than in bad soil.
Leitrim is suitable for the growing of trees due to its
damp soil conditions.
Land that was once covered by bog is often used for
silviculture.
 They are evergreen trees
 The leaves fall off when old but grow back straight
away
 The Sitka Spruce is the most common coniferous tree
in Leitrim.

The sitka spruce is the most common tree in Ireland
The sitka spruce is a coniferous tree
Their timber is used for fences, roofing, floors and tools
Many of the coniferous trees are not native to Ireland e.g
sitka spruce
Sitka spruce is used for firewood, woodpellets for burners
Saw dust from the sitka spruce is used for the bedding of
livestock
As it is a soft wood it grows quicker and it is less expensive
than hardwoods
The sitka spruce is the most common tree planted by state
forestry Coillte
DECIDUOUS TREES
 They are usually broad leaf trees.
 Their leaves fall off in autumn.
 They live to be a hundred years old.
 It’s a hard wood and it’s more expensive than soft wood
 Most of them are native to Ireland like oak, ash and
birch
 Some non-native broadleaf trees are beech and
hornbeam.
Foresters
Most Irish forests have a 40 year cycle.
A forester protects forests against insects, disease
and fire.
The foresters preserve wildlife and supervise
grazing, and help to guard the forest.
They help supervise at camping sites and picnic
areas.
Birch
 Birch trees may grow in pairs or clusters
 The silver birch is grown in Ireland
 They grow in peaty soils
 Birch nutlets are small and grown in a cone
 They have a thin bark with peels in horizontal layers
 Other trees are the yellow birch, river birch, sweet
birch and gray birch
Ash trees
 Ash is a hard wood tree
 Ash trees can prevent soil erosion
 Ash wood is hard strong and is used in the making of
shovel ,hoe and rake handles.
 In Ireland ash is used in the making of hurleys
 Hurleys can vary in length from 61 cm to 94 cm
 The game of hurling is better known as the “clash of
the ash”
 In Ireland there are two different types of ash, (a) the
mountain ash, (b) the lowland ash
THE OAK TREE
 The oak is a broadleaf tree.
 The oak timber produced is hard wood.
 The oak is a native tree to Ireland.
 The Vikings used oak wood to build their ships.
 There are 600 different species of oak.
 Oak trees can live for 800 years.
Habitats of the forest
 There are four habitats in the forest.
 1. The canopy is the tops of the trees.
 2. The shrub layer has small trees and shrubs.
 3. The ground layer with flowering plants and animals.
 4. Leaf litter with dead leaves and animals such as
earthworms and hedgehogs.
Fencing and wood uses
 Wood is used for fencing on farms and motorways
 These fences are for keeping cattle of the motorway
 Fences are made from oak, dougles fir, larch and pine.
 Wood is used for poles to carry electricity and
telephone wires.
 Fences and gates are made in different types of ways
Firewood and energy (products)
 Wood is a renewable source of energy
 Timber produces 30% more heat than fossils fuels
(coal gas oil peat)
 Certain timbers may be used to make timber products
like tables, chairs, sleigh beds, instruments and shelves
 There are 4 types of fuel 1. cut timber 2. chipwood 3.
sawdust 4. wood pellets and briquettes
