A fforestation on roadside sandesh bolakhe

  1. 1. Sandesh Bolakhe Roll No: 42 Advance Silviculture
  2. 2. Introduction  Emperor Ashoka, was the first Indian King who planted shady trees on the sides of roads and later he was followed by Moghuls but this planting was mostly Unplanned.  During the British Rule, this work was continued but it was done by the Public Workers Department.  In 1938, Chaturvedi, drew the attention of the Government regarding the arising questions for Neglecting Plantation, by preparing Working scheme for U.P roads.  In present roadside plantation is being done in several states by Forest Departments and National commission on Agriculture in India.
  3. 3. Factors of Locality and other Conditions  Climate Varise from place to place as the roads passes through areas with varying climates, the soil also varies from sandy to stiff clay with stretches of Saline alkaline soils  The borrow pits upset the natural drainage and tend to become waterlogged.  Grazing does a lot of damage to the plants.  Soil Preparation  Done usually in winter, after winter rain, when soil is easy to dig.  60cm X 60cm deep pits are dug for mangifera indica and dalbergia sissoo.  45cm X 45 cm for Eucalyptus and other species.  Alignment of rows of pits is very important from the point of view of beauty of avenue planting.
  4. 4. Choice of Species  Spps. Should be hardy, evergreen or winter decidious, wind-firm, fast growing, and fairly tall.  Should have good grown but should not have dropping branches  edible fruits and valuable timber Species are preferred.  most commonly used suitable species.  Accacia arabica, Albizzia procera, dalbergia sissoo, Eucalyptus spps, Ficus infectoria, F. bengalensis, F. glomerata, Madhuca indica, Mangifera indica, Pongamia pinnata, Syzygium cumuni, terminalia arjuna etc.  In saline alkaline soils, prosopis juliflora, Parkinsonia aculeata have proved very successful.  To break the monotony, ornnamental plants, such as Cassia fistula, Cassia javanica, bahunnia variegata, Delonix regia, Jacaranda ovalifolia, Grevillea robusta, lagerstroemia species, are planted near Kilometer stones.  In the hills, Populas nigra, Populas alba, Robinia, Acer oblongum, Alianthus altissima, etc, can be planted.
  5. 5. Method of Raising Plants  Plants have to be raised under very adverse condition, so the protection is a great problem.  Nursery grown tall plants with ball of earth or raised in containers, are usually planted.  Plants are then transplanted in nursery two or three times to enable them to develop a bushy root system  By Control of spacing: the plant become sturdy and tall  By Pruning: develops clear bole  Minimum height considered: 2.4 m for sisham, it takes 3 years to attain this height, while mango and jamun take 2 to 3 years, Eucalyptus takes 8-9 months, and 1.5m for other species
  6. 6. Protection Methods I. Construction of a mud wall with diameter 1.5 m and of equal height, round each plant II. Construction of circular open brick-work enclosure, 1.5 m in diameter and height, with mortared overlaps and top curb, round each plant III. Making a live circular hedge of Accacia arabica, Agave, etc. round each plant IV. Old coaltar drums variously cut and bent to increase effective height round each plant V. Tying of inverted Khajur (Palm) leaves on the steam of the plant all round and making a ring of brush wood or thorens round each plant
  7. 7. Tending  Requires continuous attention for proper development of plants  Stakes are used to give support to the tall lanky leaning plants  During winter, frost-tender plants like mango and jamun are protected against frost by erecting grass covers over them
  8. 8. Advantage  Advantage  Increase property values  Improvement of Air Quality  Increase in community pride  Increase in Recreational Opportunities  Reduction of noise levels
  9. 9. Some Organizations Involved  Roadside tree planting through cooperative approach- Bangladesh, 2006  Roadside Environment Committee, New South Whales  Environmental Conservation project: roadside tree palntation in Punjab, Rajasthan, Madhya Pardesh (MP) and Delhi, 1999 (36,030 plants were planted in 232 km road span)  Road Side Tree Plantation Project, July 2002 to June 2005. Bangladesh
  10. 10. Roadside plantation in Nepal  The concept of bioengineering in road construction was introduced in Nepal 40 years ago with roadside plantations in a US-assisted project on the Dhangadhi Dadeldhura highway in western Nepal.  It was later applied in the Lamosangu - Jiri highway in the country's central hills region, built with Swiss assistance.
