The project was held by Upper Lachlan Landcare at Kiamma Creek on October 31 with St Mary's Primary School.

The program teaches students about the benefits of tree-planting.

"It was wonderful to see the students so enthusiastic about planting the trees," Upper Lachlan Landcare coordinator Ruth Aveyard said.

"They could see the trees they plant today will be used by a variety of insects, birds and other native animals," Ms Aveyard said.

"The messages they sent the trees by writing on the tree guards were inspirational and delightful.

"These trees will grow healthy and strong with such positive vibes."

The Crookwell Gazette asked year 3 students what they learned:

"I learnt that you shouldn't kill all the spiders because they get rid of all those pesky flies and I also learnt that you should try and help our environment by growing more trees"

"You need to be careful when you plant trees. Don't cut down trees because bugs and animals live in the trees."

"The Kiamma Landcare taught us that we need trees to live and that we need all those insects to keep our animals alive. That you had to be careful planting trees and that willow trees might look nice but they suck up all the water and that kills living creatures that live in the water."

"The Kiamma Landcare Group taught me that there was a Water Rat living in the creek. The creek has been there for over a thousand years.

"Also, I found out that there was something called a micro-bat. We made an insect hotel. Its where a lot of different insects could live."

"I learnt about biodiversity. Biodiversity means a variety of plants and animals. I also learnt how to make an insect hotel. An insect hotel is a home for insects."
