The site is at possible risk from groundwater discharge.
The site is surrounded by sedimentary hills and is at an elevation of 300 metres. The remnant vegetation is significant as much of the Ben More Range located close by has been cleared of the original Box-Ironbark vegetation. Previous activities at the reserve have been grazing (a grazing licence was removed approximately 15 years ago) and timber harvesting activities. Saline discharge is occurring along a drainage line within the reserve and visible salt scalds are present. Therefore the vegetation is highly threatened from dryland salinity.
Vegetation Description and Composition
The EVC represented at this site is Box Ironbark (Western Goldfields) and the open woodland community is dominated by Eucalyptus leucoxylon (Yellow Gum) and Eucalyptus goniocalyx (Long-leaf Box) with a minimal shrub layer. The herbaceous layer consists of Danthonia spp. (Wallaby Grass), Tricoryne elatior (Yellow Rush-lily) and Lomandra spp. (Mat Rush).
The most significant introduced species are Briza maxima (Quaking Grass) and Briza minor (Lesser Quaking Grass). Many introduced grasses have reduced in cover abundance due to dry seasonal conditions and probable grazing pressures from hares, rabbits and wallabies.
Two salt indicator species are present being, Lolium spp. (Rye Grass) and Polypogon monspeliensis (Annual Beard Grass). Their further spread remains of concern due to salt discharge occurring nearby, but still may be just a response to the seasonal variations. Further information is needed through soil salinity testing.
Lexton North Reserve contains a good shrub layer that is excellent habitat for many small bird species
