These grasslands are a priority for protection and management as they contribute to our natural biodiversity, our history and heritage, and local amenity and community. They also provide opportunities to enhance cultural engagement, education and scientific research. Since European settlement our native grasslands grasslands.

It also urbanisation and a changing climate.

INTRODUCTION 2 Draft Native Grassland Conservation Strategy and Action Plans Draft Native Grassland Conservation Strategy and Action Plans 3 1.1 OVERVIEW The ACT Native Grassland Strategy provides guidance on the conservation of native grasslands and component species in the ACT consistent with the ACT Nature Conservation Strategy 2013–23 (ACT Government 2013a). Relatively large areas of native grassland in the ACT are now protected within reserves, so the current emphasis of grassland conservation is on management and enhancement of grassland ecosystems. This includes conserving native grassland species and communities by managing threats, maintaining and improving ecological connectivity, ecosystem function and grassland biodiversity, undertaking monitoring and research programs, partnering with the community to support grassland conservation and enhancing the resilience of grasslands to disturbance and climate change. 1.2 STRUCTURE OF THE Chapter 4: STRATEGY This chapter includes the strategy for managing native grassland and component species for This document is divided into seven main conservation. It considers adaptive strategies with key principles and management management principles for managing herbage guidelines and is structured as follows: biomass, disturbance regimes and exotic grass as habitat, including species-specific grass Chapter 1: structure and herbage biomass management This introduction chapter outlines the objectives guidelines and how these principles should be and scope of the strategy, legislation and policy implemented at the local scale. applying to nature conservation and the links between the strategy and associated action Chapter
