Rangitikei schoolchildren spent Wednesday afternoon learning about planting and stream health as part of a Horizons Regional Council freshwater initiative.
Pupils from Bulls School and South Makirikiri School - two of the region's Enviroschools - were involved and council freshwater co-ordinator Clare Ridler said it was an opportunity to educate the children about freshwater ecology.
Bulls School is in its second year of being a fully fledged Enviroschool and its pupils helped plant 400 trees and flaxes off Parewanui Rd, near a stream which is a tributary to the Rangitikei River.
Teacher Leigh Hanson said the field trip was attended by the school's Green Committee - a group of 15 pupils selected on application.
"When they walked in this morning they were all excited," she said.
