The Mentone to Mordialloc Foreshore Reserve is a long narrow coastal strip that extends from Charman Road, Mentone (Melways 86 H7) to Mordialloc Creek, Mordialloc (Melways 92 F1)
The Mentone to Mordialloc Foreshore Reserve is approximately 12.8 ha spread out over a 4.5 kilometre length. The northern portion of the reserve drops steeply from the eastern boundary down to the edge of the beach along the western boundary. The southern portion of the reserve is lower and slopes more gently down to the beach. The larger areas of mown grass, and the concrete path and promenade are not included in the Natural Resource Area. The embankment in the northern portion of the reserve has been highly modified from a former sandstone cliff, and in many parts has had foreign soil and rock introduced.
The main remnant vegetation communities in the Mentone to Mordialloc Foreshore Reserve are Primary Dune Shrubland on deep sand loams furthest from the beach, grading into Foredune Hairy Spinifex (Spinifex sericeus) Grassland on deep calcareous sands next to the beach. The introduced Marram Grass (Ammophila arenaria), originally used to stabilise dune systems, has become naturalised and so well established that it its removal is now impracticable.
The Mentone to Mordialloc Foreshore Reserve, in conjunction with the Aspendale to Carrum Foreshore Reserve is a major tourism and coastal recreational venue for Melbourne. The Mentone to Mordialloc Foreshore Reserve has high conservation values with the presence of locally and regionally significant flora species, and the opportunity it presents to be established as a major habitat corridor. It also provides a significant propagation material resource and high values as an educational resource.
