WHAT IS TREE TRANSPLANTATION Transplanting is the term used to describe the digging and replanting of trees from one location to a new location.

Due to the wide extent and morphology of tree root system, transplanting of trees usually involves substantial removal of roots.

The whole transplanting process in particular for large trees is an engineering feat and requires substantial involvement of resources and time.

A decision to transplant a tree should be based on a balancing consideration of its conditions (e.g. form, health and structure), size, species, conservation status, amenity value, suitability for transplanting, environmental and cultural factors, functional and engineering considerations and cost effectiveness. https://www.greening.gov.hk/filemanager/content/pdf/tree_care/Guidelines_on_Tree_Transplanting_e.pdf

WHY THE REASONS BEHIND TREE TRANSPLANTATION VARIES FROM PROJECT TO PROJECT

TREE TRANSPLANTATION IN PROGRESS IN KARNATAKA

Source: Tree Transplanting: Success Stories of Trees Transplanting at Karnataka, India

For example in, Karnataka, India the need for Tree Transplantation came when there was the construction of Metro in the city and the people as well as the government wanted to save the trees which were going to be cut down. they city and the government came together and successfully Transplanted 108 trees.

In Delhi the Delhi Forest Department will soon gets its first official Tree transplantation machine.

HOW IS TREE TRANSPLANTATION DONE UNDERGROUND SPACE For most mature trees, you will need space to dig two big holes: one to dig the tree out, and one in the new tree location.

The size of the hole is estimated by measuring the trunk diameter about 12 inches (305mm) from the ground. If the diameter is 8 inches (203mm) or more, the width of the rootball must be 10 to 12 inches (254mm – 305mm) per inch of trunk diameter.

For example: A tree that is 12 inches (305mm) in diameter at the base requires a hole that is at least 10 to 12 feet (3 to 3.6m) wide to preserve roots, plus a little more room to maneuver the tree out and in.

DIGGING STAGES

PRE-LIFTING OPERATIONS Tree lifting operations shall be carefully timed so as to enable direct delivery to the receptor site.

No transplanting operations should commence until either the receptor site or the holding nursery is fully prepared.

Tree uplifted must be transplanted and watered the same day.

Watering before lifting is recommended.

Before uplifting, the outer edge of the previously dug trenches shall be loosened from the surrounding soil, and the root ball can be shaped with taper on the sides, slanting inward toward the base.

Damp hessian is placed on the sides and across the tip of the ball and pinned. The hessian should cover the full circumference of the root ball with bottom skirt hanging out.

LIFTING AND HANDLING OF ROOT-BALLED TREES Lifting should be done by direct lift, with padded protection for the tree, using a machine of appropriate capacity connected to the support around the root ball, not to any other part of the tree.

Tree should not be lifted by the trunk as this can cause serious trunk injury but by its root ball which should be properly prepared and wrapped.

PROPER LIFTING UP BY THE ROOT BALL, NOT BY THE TRUNK

CONTAINERIZED ROOT BALL Trees in containers are more resistant to root damage during transportation.

This is a recommendable method of transplanting as the root ball is well protected and lifting of the boxed root ball during transplanting will give better protection during the transplanting operation and enhance better establishment of the tree afterwards.

STORAGE If the tree must be removed but cannot be replanted right away, the rootball will need to be boxed and the tree will need to be stored somewhere and watered.

Storing the tree for six months or more is better for the tree than digging it up, storing it for a few weeks or months and then transplanting it.

The longer storage time allows for trees to grow new feeder roots to absorb water and nutrients.

PREPARATION OF RECEPTOR SITE Trees will not tolerate highly compacted soil, which should be broken up over as large an area of the site as possible.

Planting pits should be provided with drainage to allow effective percolation of water.

A PLANTING HOLE THAT IS TWO TO THREE TIMES THE WIDTH OF THE ROOTBALL AT THE SURFACE IS OPTIMUM FOR MOST SITUATIONS. ROOTS WILL GROW VIGOROUSLY TOWARD THE BETTER SOILS NEAR THE SURFACE (DOTTED LINE) RATHER THAN BEING TRAPPED IN THE PLANTING HOLE.

AFTERCARE All newly planted trees are subject to stress until a normal spreading root system has developed.

The primary objective of planting site preparation is to provide a quantity of backfill soil that promotes rapid initial root development and does not restrict root spread beyond the planting hole In addition to watering, aftercare may also include misting, mulching, support hardware, and follow-up visits.

NEWLY TRANSPLANTED SHOULD BE PROTECTED WITH ROBUST PROTECTIVE FENCING FROM ALL CONSTRUCTION ACTIVITIES AND ADEQUATE PROTECTIVE MEASURES SHOULD BE IN PLACE TO AVOID ADDING FURTHER STRESS TO THE TREES

BENEFITS OF TREE TRANSPLANTING Environmental degradation is currently the most critical area of concern not only in India but also globally and the pace of degradation is increasing at a rapid rate.

Urbanization, Mining, Infrastructure growth etc. have resulted in deforestation which is adversely impacting the weather and also leaving behind severe repercussions on Human life.

When it comes to re-planting the trees and improving the green cover, there is a significant ecological imbalance and disparity.

The bigger and moderately mature living trees will provide wide range of benefits to us in terms of air filtration, produce sufficient oxygen, supporting the flora and fauna, reducing the soil erosion, help conserve the energy, reduce the UV-B sun rays impact on us and also acting as the carbon dioxide sinks etc.

Whereas the newly planted seedlings and very young trees will of course help improve the extent of green cover but a no-match in comparison to value benefits from a bigger tree.

Hence for a sustainable future, it is very much essential for all of us together to conserve the trees and protect our environment to the extent possible. www.volvotrucks.in
