The park's latest themed land has been inspired by its support for international conservation charity World Land Trust.
Popular car ride Toadie's Crazy Cars becomes Jungle Rangers, with an updated track, Jeep-style vehicles and theming.
River Rafts will be a mini log flume ride that previously operated at the Weymouth SEA LIFE Adventure Park as Crocodile Creek.
The current children's drop tower ride Treetop Hoppers will offer views of the refreshed area.
Some animals from elsewhere in the park will be re-located to the new area, including their resident tortoises and capybaras.
Families will find out about the importance of saving the world's rainforests.
In another section of the park, the Flying Jumbos ride will become Elmer's Flying Jumbos in 2020, with the classic ride being re-located and re-themed.
Elmer the Patchwork Elephant is a children's picture book series by the British author David McKee.
