Environment Minister Dr. Harsh Vardhan will lead a month-long drive to plant saplings to mark Van Mahotsav which will begin tomorrow. The plantation drive will be organised at Ram Lila Park, C. C Colony and Model Town tomorrow. <br/><br/>He will plant and distribute saplings for plantation to local residents. According to an official release, Dr.Vardhan has advised people to plant native trees because they readily adapt to local climate, integrate into the eco-system. <br/>'<br/>Van Mahotsav is usually observed in the first week of July every year and is celebrated on different days in different parts of India.
