Scientific name: Eucalyptus sp. Howes Swamp Creek
Profile last updated:
09 Aug 2024
Description
The taxonomic status of Eucalyptus sp. Howes Swamp Creek is uncertain and it has yet to be described as a species. E. sp. Howes Swamp Creek is a tree to 25 m tall with a thin wavy fibrous grey/brown bark stocking, and smooth cream branches. This species has distinctive heart-shaped juvenile leaves 2-4 cm long, adult leaves 9-15 cm long, the fruit has three valves. The taxon is morphologically similar to, and is easily confused with E. viminalis.
Distribution
E. sp. Howes Swamp Creek occurs within a small area of alluvium on Howes Swamp Creek in the Mellong Swamp Complex within Wollemi National Park.
Habitat and ecology
- The lower Mellong Ck area where this species occurs, is part of a large wetland complex comprising eight swamps, each approximately one square kilometre in area. These swamps dry out on the surface after less than three months of drought. This swamp complex is unique within the Sydney Basin.
The area where this species is found has a sheltered south facing aspect on alluvium adjacent to permanent water bodies.
- Very little is known of the species' ecology however it appears to respond in a manner typical of Eucalypts to fire, including resprouting from the rootstock and epicormic shoots.
- Associated species include Eucalyptus piperita subsp. piperita, Angophora floribunda, E. parramatensis and E. amplifolia on the opposite side of creek. Understorey species include Dillwynia glaberrima, Acacia parvipinnula, Banksia spinulosa, B. serrata, Oxylobium pultenaea and Melaleuca thymifolia.

Threats
- As it is growing in a remote area, this species is relatively free of threats. However, the area is prone to frequent fire events, with at least three fires affecting the locality within the last ten years.
- As there is only one known population of this species, it is potentially vulnerable to stochastic events.
- Insufficient understanding of taxonomy.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Develop and implement a fire management plan specifically to protect this species from over-frequent fire.
- Report any new records of this species to the OEH.
