The theme is ‘connecting people to Nature', and the planned activities aim to "reinforce and promote our responsibility in caring for and respecting the environment and the world we live in", the organisers said.
Park general manager Michelle McGeorge, who has been a key driver in the campaign, said that the expo was part of on-going activity to educate and promote awareness about PNG's flora and fauna.
"The Nature Park has partnered with BSP on this event for the last five years and this year we look forward to another 20 organisations joining us to spread the message on how we can save our planet," McGeorge said.
Taking place at the Port Moresby Nature Park from 9am to 3pm on Saturday, June 3, park rangers will escort visitors on tours and showcase the many native animals including the bird of paradise, tree kangaroos, wallabies, snakes, crocodiles, hornbills and multiple parrot species.
There will also be face painting, colouring in activities, bouncing castles and other fun and games.
Gate fees are K7 for adults, K3 for children from three to 12 years, and K5 for students with identification. For more details, contact the Port Moresby Nature Park on 326 0248.
