Bits and bobs about Castlereagh Nature Reserve in north western Sydney, NSW, Australia....

1. Cooks River/Castlereagh Ironbark Forest
"Cooks River/Castlereagh Ironbark Forest is a community that ranges from open forest to low woodland, with a canopy dominated by broad-leaved ironbark (Eucalyptus fibrosa) (pictured) and paperbark (Melaleuca decora). The canopy may also include other eucalypts such as woolybutt (E. longifolia). The dense shrubby understorey consists of Melaleuca nodosa and peach heath (Lissanthe strigosa), with a range of ‘pea’ flower shrubs, such as Dillwynia tenuifolia, Pultenaea villosa and Daviesia ulicifolia (can be locally abundant). The sparse ground layer is made of grasses and herbs, including kangaroo grass (Themeda australis), weeping meadow grass (Microlaena stipoides var stipoides) and Entolasia stricta."
2. Scribbly Gum Woodland
"Castlereagh Swamp Woodland is a low woodland community that occurs in poorly drained depressions along intermittent watercourses. Castlereagh Swamp Woodland often has dense stands of paperbark trees (Melaleuca decora) (pictured) along with other canopy trees, such as drooping red gum (Eucalyptus parramattensis ssp parramattensis). The shrub layer is not well developed and is mostly made up of young paperbark trees (Melaleuca decora and M. linariifolia). The ground layer has a diversity of plants that tolerate waterlogged conditions, such as swamp pennywort (Centella asiatica), common rush (Juncus usitatus) and Goodenia paniculata."
Castlereagh Swamp Woodland is listed as an endangered ecological community under the Threatened Species Conservation Act 1995.

Along the track, at various locations, are signs stating that rehabilitation is occurring, but there aren't any signs of weeding or planting. Perhaps these areas are left to regenerate naturally?
Most trees are relatively young, with dark, rough bark - Broad-leaved Ironbarks (Eucalyptus fibrosa). Many trees also appeared to be blackened by fire. Other trees, like the one pictured below, had smooth, light-coloured bark with noticeable 'scribbles' - Hard-leaved Scribbly Gums (Eucalyptus sclerophylla) and scratches, presumably from Brush-tailed Possums (Trichosurus vulpecula).(
The biggest variation in vegetation composition was the variety of shrubs. The photo below was taken in a particularly verdant patch.
There was some grass cover, but often the ground was bare. In some places, virtually nothing was growing, perhaps due to soil compaction from when the site was a commercial forest - Castlereagh State Forest - I'll blog about that another day. Over time, I hope to familiarise myself with the different plants and animals of the Reserve, but for now I know virtually nothing. The shrub in the foreground is probably a young paperbark - White Feather Honey-myrtle (Melaleuca decora).
