Eucalyptus baueriana subsp. thalassina

This stand of approximately 50 Werribee Blue Box trees occupies the southern bank of the Werribee River in Parwan. This area is part of the traditional lands of the Wadawurrung people.

The stand is comprised of approximately 15% large or very large trees, 25% medium, and the remainder smaller recruitment trees. Friends of Hopetoun Park and Parwan Gorge

have reported that this stand has the most numerous specimens and best natural recruitment of any in the local area.

There are also a number of Werribee Blue Boxes on the northern bank of this section of the catchment, with at least 3 considered to be of Regional significance (T12431, T12432, T12433). Several other specimens in the area are currently being assessed.

The Werribee Blue Box population is estimated to be only a few thousand, most of which occur in the northern part of the distribution along theCoidamaiandDjerriwahrrCreeks, which flow through Lake Merrimu Reservoir Reserve and Long Forest Flora Reserve.
