There are over a dozen threatened vegetation communities mapped in the Huon Valley area outside of the World Heritage Area, these are predominantly made up of four key eucalyptus species communities dominated by gums or peppermints. See below brief descriptions adapted from From Forest to Fjaeldmark: Descriptions of Tasmania’s Vegetation (Edition 2).
Vegetation community dominated by Black Gums
Eucalyptus ovata forest and woodland, TASVEG code: DOV
This community is generally found growing on drainage flats and moderate to poorly drained fertile soils. These forests have been cleared extensively from river valleys and flats for agricultural development, so old growth stands of this forest are very rare. Trees are found at less than 10m to over 20m tall in this community. White gums are often the subdominant species.
Vegetation community dominated by Blue Gums
Eucalyptus globulus dry forest and woodland, TASVEG code: DGL
This community is found on dolerite ridges, slopes and flats. Blue gums are found at less than 20m to about 40m tall in this community. Other eucalypts share this forest or woodland community, including black peppermints, white peppermints, white gums, black gums and stringybarks.
Vegetation community dominated by Silver Peppermints
Eucalyptus tenuiramis forest and woodland on sediments, TASVEG code: DTO
This community is found on dry sunny sites. Silver peppermints are found at 25m or less in this community. Other eucalypts share this community, including snow gums, candlebarks, white gums and stringybarks. Due to frequent fires allowing for rapid replacement there old growth stands of this forest are very rare.
Vegetation community dominated by Black Peppermints
Eucalyptus amygdalina forest and woodland on sandstone, TASVEG code: DAS
This community is found on undulating sandstones with deep soils and good drainage. Black peppermints are found at 25m or less in this community. Stringybarks and white gums are often found to be subdominant in this community with silver wattle as a common understorey tree.
