Charlie and Capt'N Fritz teach children about the giant freshwater crayfish in a new book

The book has been written by a pair from the U.S who visited Flowerdale's Lobster Ponds Haven in 2016 while on an environmental study tour.

Now, the book, Charlie and Capt'N Fritz's Trek into the Rainforest, has been turned from a PDF into a physical book in a fundraising effort for the NW tourist attraction and education centre.

The book follows a young girl, Charlie, and her dog as they explore a nearby forest and cross paths with a crayfish, who tells them all about how their species can be protected.

Lobster Ponds volunteer Ray Hyland helped get the book published.

He said it was wonderful to have a book that encouraged children to learn more about this unique creature, and to engage in conservation.

"I think it's important to get children interested in not just saving the environment, but learning about this animal which are at the situation of near extinction," Mr Hyland said.

"This lobster is particularly important to the north of Tasmania, being endemic to this part of the state."

He said he'd been in contact with one of the authors recently, senior environmental studies major Robert Harris, who was "really pleased" that the printed book was up and running.

Profits from book sales will go towards the Lobster Ponds Haven and Cafe, which is run by volunteers.

The book will be formerly launched on Saturday, April 3. There will be multiple reading sessions over the day.

More information about the book and authors can be found online.

Copies can be purchased at the Lobster Ponds Haven.
