The BBMP's responsibilities include planting and maintaining street trees. The BBMP has embarked upon numerous tree planting schemes over many decades and with varying levels of success. The most notable period of planting is held to be the period of 1982 and 1987 when Chief Minister R Gundu Rao appointed forest officer S G Neginahal to green the streets of Bangalore with more than 15 lakh trees. His systematic plantation program involved the establishment of new nurseries, the installation of tree guards, a five-year monitoring program and the replacement of any failed plantings. The reported success rate was 97% and most of the mature trees along Bangalore's major avenues date to this era.
