Local Land Services officer Mark Thomas said the field day will cover identification of native grasslands and native plant species, legislation around native grasslands and communities, and resources available to landholders.

"Native grasslands play an important role in our landscapes, not only in pasture production for livestock but also ecosystem services," Mr Thomas said.

"Understanding these grasslands, where they are found, and how to manage them is essential in keeping them functioning and sustainable."

Participants will hear from senior land services officer (pastures) Clare Edwards who will explain how to identify native pasture species and explain their value within the Central Tablelands landscapes.

"Many pasture species are flowering and seeding at the moment so it is an excellent time to assess your pastures," she said.

"Knowing what native species you have on your property is the first step in their management.

"Most pastures in the Central Tablelands contain large numbers of grass and other herbaceous species. The dominant species, usually the grasses, determine the pasture characteristics."

Ms Edwards said the composition of a pasture varied from year to year depending on climate, grazing and fertiliser, which gave producers the scope to alter species composition to meet management goals.

The Central Tablelands Native Grasslands Field Day will take place on Friday, November 22 at the Bob Hooper Community Centre in Fleming Street, Oberon.

Morning tea will be provided and the event will also include a visit to the Campbells Travelling Stock Reserve for a practical demonstration.
