While you are creating a plantation site ensure not to forget to plant the flowering plants and bushes like amaltas, gulmohar, jakarnda or kachnar. Flowering trees like madhumati or bougainvillea are also good flowering plants that form useful bio fencing.
What exactly is pollination?
It is the transfer of pollen from a male part of a plant to a female part of a plant that results in fertilisation and the production of seeds. This transfer is mostly by wind or animals. Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower.
If a site has no flowering plants then the bees, butterflies and other insects will not get attracted and hence forth no pollination process will take place in that area. Bees, butterflies, insects, ants are the pollinating agents and they attract only when there is something for them to eat. You have to basically create a magnet to attract them so that more and more can come.
Let it be any afforesting project or large gardens do ensure to have flowering plants and trees because pollination has to take place. A zone has to be created for bees & butterflies and insects to be attracted and carry out the pollination process.
