4. Road Arboriculture Growing of trees along road side is called road arboriculture. Trees can be grown on both urban as well as rural roads. The trees should be planted at least 12 m way from the centre line of the carriage way. The basic aim of planting the tree away from the centre line is to maintain clearance at least equal to carriage way width at the level of crown of trees. 4

5. Objectives of Road Arboriculture 5 The trees are grown on road side to serve the following objectives. • To provide attractive landscape of road side. • To provide shape and comfort to road users and make journey more comfortable.

6. To prevent soil erosion from the roadside. To reduce headlight glare during night driving by the planted shrubs. To intercept the annoying sound waves and fumes from road vehicles by the planted trees. It provides shed to the road user. 6

7. Patterns of Tree Planting 7 Trees are generally grown along both sides of the road. As already stated that, the spacing of the trees rows the centre line of carriage way should be at least 12 m, in case trees of wide crown type.

8. Care of Trees Protection of Trees: After planting the trees have to be looked after from the attack of stray animals. Following measures can be adopted for the protection of trees. 8

9. Iron guards : Iron enclosure are made around the trees to protect them. Bitumen drum guards : P.W.D. has lot of used bitumen drums in its possession. Barbed wire fencing: In this system four wooden bullies are driven at four corners around the tree pit an bardbed wire wrapped around them. 9

10. Maintenance of Trees: Watering : Watering is an essential feature of tree maintenance. Method of watering and interval of watering depends on type of tree, the land, climatic conditions, water availability etc. Hoeing : Soil around the tree stem should be kept loose. This helps in fast growth of the tree. 10

11. 11 Protection from frost: Plants which are likely to b e affected by cold should be provided protection by coveringthem by thatching. Keeping trees straight: if plants get inclined they should be given support with the help of bullies against the slope. This helps keep the trees up right.

12. 12 Conclusion : The roadside trees are a cheaper and positive way to preserve and improve environment. There were the Social Forestry programmers, which yielded results, but failed due to the lack of follow up actions and also in wrong selection of the tress which were not natural to our country. The same programmes should be re implemented by removing the errors.
