A source, who wishes to remain anonymous, contacted the Daily Liberal and revealed the council had restructured the department and it is alleged three positions were made redundant, including that of the community participation facilitator.

The other two positions believed to have gone are those of the team leader - horticulture and an aborist.

The caller also said there had been no consultation with community groups and most only found out when the previous facilitator sent an email to say she was finishing up.

Dubbo City Council confirmed a restructure of the department was taking place.

"Parks and landcare division is undergoing changes in employee structure to better align employees and functions of the division," director of parks and landcare, Murray Wood said.

"These changes are required to ensure operational services across a number of different areas such as bush regeneration, reserves, parks, open space, sporting facilities and the Regional Botanic Gardens can be maintained."

Council did not respond to questions from the Daily Liberal about the number of redundancies, affected positions, or how those positions would be covered.

They also did not respond to a suggestion the changes had been made to accommodate groundskeeping requirements for the new Barden Park facility.

The role of the community participation facilitator is to liaise with community and volunteer groups and with no one filling that role, groups such as the Dubbo Field Naturalist and Conservation Society and Friends of the Botanic Gardens have no official channel to talk to council.

Field Nats president Tim Hosking said they had not been contacted or consulted by council about the loss of the facilitator but he was aware the liaison was gone.

"We are currently writing to council to clarify the situation. We haven't been advised but I understand there is no one in that liaison role and it is one we greatly value," Mr Hosking said.

"We interact with council over a number of issues, the main one being the Wattle Grove and those interactions have been positive. We hope that will continue once the council decides how to cover that role."
