Yina Nature Reserve vegetation mapping was undertaken by Dr John T. Hunter in 2003 by contract for the NPWS Northern Tableland Region. Yina NR is located within the New England Tablelands Bioregion and the Northern Tablelands Botanical District and is approximately 10 km east of Armidale. The reserve incorporates 101 ha within the Armidale Dumaresq Shire. The reserve was formally known as Hillgrove State Forest.

The vegetation of Yina Nature Reserve is described and mapped (scale 1:25 000). Four communities are defined based on classification (Kulczynski association). These four communities were mapped based on ground truthing, air photo interpretation and landform. Two communities are Endangered and one considered as vulnerable, the fourth is considered to be poorly reserved. Most communities are of woodland and open forest structure. The communities show considerable variation and intergrade along common boundaries and in particular on intermediate soil types.
