"Usually I take out 25 students at a time," Lebo said. "We go out there for a day, and they come out once every two weeks for the whole term.
"We want it to be available to all the kids and also connect it to their te reo studies. For Forest School, we teach half te reo and half English.
"Then connect it with science as well by learning about the bush and how to care for it. I just think it is very rare and innovative."
Lebo said they are the only intermediate school in New Zealand running a Forest Programme for all of their students.
"I think that is pretty amazing."
Whanganui Intermediate will receive $1000 to go towards their environment project, plus 200 native trees from Trees That Count for the school grounds.
"Moving forward, we have to think about where we will put the trees. How do we involve the kids, because student voice is important and they are connecting it with our curriculum."
Programme creator Ruud Kleinpaste will visit Whanganui Intermediate in July to help the school develop their chosen environmental project further and help teachers identify ways to incorporate the environment as an immersive part of the curriculum.
"He will come here and talk about how do we integrate this beautiful naturalist education into our other subject areas.
"The trees will provide a nice outdoor classroom space and how we can integrate all the programmes for a clean connection."
