Recently we have been reading about the tree census being conducted by the MCGM. So let us find out more.
What is a tree census or survey?
Tree census means simply counting trees. In a survey, we would also like to find out other interesting data- like where are the trees, what are the types of trees, what are problems faced by trees, etc.
Why should we do it?
It is important to know about the quantity and quality of tree cover. Serial surveys tell us if trees are increasing or decreasing. We can know the distribution of species. Data about health of trees helps to detect epidemics and other challenges. So tree survey is the basis for planning tree- plantation, tree maintainence systems
How is it done?
First one should define 'tree', 'shrub' etc. A tree is usually a plant more than 6 feet in height. Then the tree is located, counted and described in forms- when done manually. Some form of coding is required to make it easy to enter and analyse data. This time MCGM is using GIS- I dont know exactly how they do it.
Then data is tabulated and analysed
MY OWN TREE SURVEY- HOW? WHY?
Yes, you can choose your Society/ street or garden to do your own tree survey.
If possible take a youngster along- it is a great way to spend quality time with them. You will need to set aside 1-2 hours of the forenoon. Be equipped with a writing pad, survey sheet and a field guide such as 'Trees of Bombay" (BNHS). Just fill up the survey form. After checking for completeness, take the data home and upload results to your blog.
Other than the benefit of teaching our offspring about trees and bonding with them- doing your own tree survey helps you to keep a watch on the trees in your locality by establishing a baseline. And you can also detect any fraud or error by MCGM- look what happened with the DP!
Best wishes for your tree survey! It will be a great way to spend a morning!
