Venue: Different places of Kathmandu valley
The environmental work, mostly greenery, need long time to give its positive impact. If our effort don't match with the nature of surrounding, it will bring disaster in future. For example: The plantation of Lahare Peepal around the ring road to make green belt in Kathmandu transform in to disaster due to improper selection of species in urban greenery work. These trees are weak rooted, landing down and occur several accident on roadside. Realizing the facts we organized a research about the proper selection of species of plant with suitable spaces. The conclusion of the research paper is about the greenery work in urban and remote as well as populated and open spaces. To make more efficient work we have proper selection of species of seedlings according to space available with its long-term utilization.
