Editing Eucalyptus regnans (section)

=== Ecological community ===
The majority of the endangered [[Leadbeater’s possum]] population lives in mountain ash forests (''Eucalyptus regnans'', ''E. delegatensis'' and ''E. nitens'') in the Central Highlands of Victoria. The possums use hollows in old trees for nesting and shelter and forage for arboreal [[arthropods]] under bark.<ref name="BATR1997"/> The vegetation structure of these forests enables the possums to travel through them.<ref name="BATR1997"/> Both Leadbeaters possums and [[yellow-bellied glider]]s feed on the sap from the trunks and branches.<ref name="GrovesRide1982">{{cite book|author1=Groves, R.H. |author2=Ride, W.D.L |title=Species at risk: research in Australia : proceedings of a Symposium on the Biology of Rare and Endangered Species in Australia|url=https://books.google.com/books?id=zz0QAQAAMAAJ|year=1982|publisher=Australian Academy of Science|isbn=978-0-85847-102-3}}</ref> [[Koala]]s feed on the foliage, though it is not one of their preferred forage species.<ref name="Griffiths2001">{{cite web|title=Victoria's koala management strategy|publisher=Biodiversity and Natural Resources Division, Department of Sustainability and Environment|date=September 2004|url=http://www.depi.vic.gov.au/__data/assets/pdf_file/0014/220424/Koala.pdf|archive-url=https://web.archive.org/web/20150216085914/http://www.depi.vic.gov.au/__data/assets/pdf_file/0014/220424/Koala.pdf|url-status=dead|archive-date=2015-02-16|access-date=16 February 2015}}</ref>

In a small area of rainforest in [[Yarra Ranges National Park]] in Victoria, nine [[epiphyte]] species were observed growing on ''Eucalyptus regnans'', the most prevalent of these being the [[liverwort]] ''[[Bazzania adnexa]]''.<ref name="Kellar2006">{{cite journal|last1=Kellar|first1=Claudette|last2=Short|first2=Megan|last3=Milne|first3=Josephine|author-link3=Josephine Milne|date=August 2006|title=Epiphytes on ''Nothofagus Cunninghamii'' and ''Eucalyptus Regnans'' in a Victorian Cool Temperate Rainforest|url=http://search.informit.com.au/documentSummary;dn=666917975077649;res=IELHSS|journal=The Victorian Naturalist|volume=123|issue=4|pages=222–229|issn=0042-5184}}</ref>

The spur-legged phasmid (''[[Didymuria violescens]]'') is a leaf-eating insect that can defoliate trees during major infestations such as one experienced at [[Powelltown]] in the early 1960s.<ref name="Mifsud2002"/> Leaves and buds are eaten by the larvae and adults of the chrysomelid leaf beetle ''[[Chrysophtharta bimaculata]]''.<ref name="Forestry Tasmania 1999">{{cite web|title=Tasmanian eucalyptus leaf beetle|work=Identifying pests in Tasmania’s forests|publisher=Forestry Tasmania|date=March 1999|url=http://cdn.forestrytasmania.com.au/uploads/File/pdf/forest_health_leaflets/insect_pests/pestsinfosheet1leafbeetle1.pdf|access-date=9 February 2015|archive-url=https://web.archive.org/web/20150209041945/http://cdn.forestrytasmania.com.au/uploads/File/pdf/forest_health_leaflets/insect_pests/pestsinfosheet1leafbeetle1.pdf|archive-date=9 February 2015|url-status=dead}}</ref> Stressed trees can be damaged by the eucalyptus longhorned borer (''[[Phoracantha semipunctata]]''), which burrows into the trunk, which exudes a red stain. Eucalypt weevils of the genus ''[[Gonipterus]]'' commonly damage ''E. regnans'', while the tortoise beetle (''[[Paropsis atomaria]]'') is a common pest of plantations.<ref name="CABI"/>
