Mapping Bangalore’s Trees

Bangalore’s amazing ecological diversity is one of the few redeeming gifts of the British. Many of the trees you see in Bangalore are not native species, but have come to be ubiquitous to the city.

Unfortunately, mass development (destruction?) has lead to a gradual decline of the city’s green cover. There’s something wrong with our definition of development when it involves the destruction of the city’s lungs. We haven’t learnt any lessons from Delhi or China. And we seem to be headed down a path of no return.

Between the proposed elevated corridor and a myriad of other projects ranging from road widening to the construction of steel flyovers, the government is on course to chop approximately 40,000–50,000 trees in the next 2–3 years.

The first tree mapping workshop at Cubbon Park

As a part of the Citizens for Bengaluru movement, I will be leading an effort to map all of Bangalore’s trees. The objective of the effort is to have open sourced data of all of Bangalore’s trees. This will be used to help the city keep a vigil over its trees and to track the diversity of species we could potentially lose should we continue to destroy our ecological heritage.

The effort has already begun, with the first tree located at Chalukya already mapped.

Once we have enough hands on the ground mapping Bangalore, we expect to have a tree map of Bangalore covering at least 75% of Bangalore’s green cover in 4 months.

The data we collect will help us filter trees according to ward, species, height or tree circumference.

We will also be able to calculate the trees value generation in Rupees per year, based on the services it provides, such as generation of oxygen, water retention in the soil, and climatic contributions that help us sustain our crops and non-plant life.

In future phases, we will continue our work to include lakes and other vital resources required for the sustenance of Bangalore as a city.
