1 Introduction

Zieria granulata is a tall shrub belonging to the Rutaceae family. The species is endemic to the Illawarra region of NSW where it occupies the coastal lowlands and escarpment slopes between Oak Flats and Toolijooa. Z. granulata has been recorded from 26 populations (or 97 highly fragmented sites) within its natural range of 22 kilometres, with the vast majority of sites located on freehold land.

The natural habitat of Z. granulata has been extensively cleared since European settlement and much of its remaining habitat is fragmented and highly degraded. A large number of threatening processes are operating at Z. granulata sites.

This document constitutes the formal NSW and National Recovery Plan for Z. granulata and as such considers the requirements of the species across its known range. It describes the current understanding of the species, documents management actions undertaken to date and details the recovery program for the species over the next five years, and the parties responsible for implementing it.
