Normally when a complex is planned to construct a multistory housing apartment in a compact city like Dhaka, the rich ecology there are left unattended and unwatered for the long period between the agreement signing (ecology owner & construction company) and authority approval obtaining- normally 12 to 18 months.
Most of the plants die in the mean time. Slum dwellers collect some for fuel wood. The left over are bulldogged and thrown away by the company while start construction.
