Restoring Nutritional Landscapes
Disturbance from logging and fire has drastically altered forest distribution and composition in south-eastern Australia, leading to widespread loss of ecological function and biodiversity. In Victoria alone, 115,000 ha of known or likely threatened species habitat was logged from 2005-2020. Silvertop Ash (Eucalyptus sieberi) is a disturbance-adapted native eucalypt species that is increasingly dominating these areas. Unfortunately, Silvertop has high levels of herbivore deterring toxins and is a poor-quality food source for Australia’s most iconic eucalyptus leaf-eating mammals, greater gliders (Petauroides volans) and koalas (Phascolarctos cinereus). In addition to decreasing the nutritional quality of forests for these animals, disturbance-related proliferation of Silvertop Ash is causing substantial reductions in overall biodiversity and landscape resilience.
In 2021, Envite partnered with the Australian National University (ANU) on an ambitious project aiming to reverse the cumulative impacts of logging and fire on eucalyptus tree species diversity in East Gippsland forests, with a focus on restoring and improving greater glider habitat. Together, we established a series of forty 0.25 ha experimental plots (10 ha in total) to develop and refine methods for future upscaling across the landscape, using a previously logged (~3 years prior) Immediate Protection Area that burned in the 2019/20 bushfires as a case study.
The methods being trialed include:
- Ecological thinning of Silvertop Ash;
- Silvertop thinning plus supplementary seeding of more diverse, locally appropriate eucalyptus tree species with a focus on improving the nutritional landscape for greater gliders;
- Thinning and supplementary planting of the same, locally-appropriate eucalyptus tree species; and
- Control sites with no intervention, used to assess the efficacy of our actions against ‘business as usual’.

Community-led Recovery of the Gippsland Banksia and Betka Bottlebrush
The Gippsland Banksia (Banksia croajingolensis) is known only from a single drainage line South of Shipwreck Creek in the Croajingolong National Park, a site that was severely burnt in the 2019/2020 megafires. Very little is known about the biology of B. croajingolensis. There is even a question about its origin, with Flora of Victoria suggesting that it may be a hybrid between other species with which it co-occurs.
The Betka Bottlebrush (Callistemon kenmorrisonii) is one of a handful of rare and endemic Callistemons restricted to Far East Gippsland. C. kenmorrisonii is only known from two small populations growing on granite rock bars along the upper Betka River, one where the river intersects Stony Peak Road and one at Roger Track, in Wingan State Forest. Both populations were severely burned in the 2019/2020 Black Summer Bushfires, and have since also been impacted by numerous flooding events following abnormally high rainfall in the years following the fires. There are unanswered questions as to the origin of C. kenmorrisonii, with suggestions that the species may be a hybrid swarm involving C. citrinus and C. subulatus.

Southern Pink Underwing Moth Habitat Restoration
The Southern Pink Underwing Moth (Phyllodes imperialis smithersi) and its food plant Carronia multisepalea stronghold occurs in critically endangered Lowland Rainforest of Subtropical Australia the Northern Rivers regions of NSW.
This project supports professional bush regenerators to systematically control weeds degrading rainforest at 11 sites where Carronia multisepalea and Southern Pink Underwing Moth larva are known to occur.
Project partners include NSW National Parks and Wildlife Service, Traditional Owners, Rous County Council, Big Scrub Landcare and the local community.
Project sites are areas of high biodiversity and conservation significance including World Heritage listed Nightcap National Park and Big Scrub Rainforest remnants.

Bushfire Local Economic Recovery Fund: Bungawalbin Community Bushfire Recovery
The bushfires of 2019-2020 burnt through almost the entire Bungwalbin area in Richmond Valley LGA devastating the local community and habitat for threatened species and ecological communities.
The Bungawalbin Community Bushfire Recovery Project is supporting ecological restoration, employment and strengthening community resilience through implementation of bushfire recovery activities across public and private land. The project involves a partnership between the local community, Bungawalbin Landcare, Bandjalang Traditional Owners and NSW National Parks and Wildlife Service.

Bungwalbin Bushfire Recovery for Wildlife and Habitat
In 2019/20, fire burnt through 98% of the 12,250 ha Bungwalbin group of 7 NSW National Park Reserves in in north-eastern NSW impacting habitat for a range of threatened species and ecological communities. Envite, along with its partners, were tasked with undertaking recovering works to restore native habitats.

Clarence River Rehabilitation
The State Government engaged Envite to undertake restoration and revegetation works along 7kms of riverbank across 22 properties on the Clarence River. These works support instream revetment works for long term erosion control.

Gippsland Drought Employment Program
Following more than three years of damaging drought conditions in the East Gippsland region, the State Government funded the Gippsland Drought Employment program to provide flexible, temporary employment for farmers and individuals from related industries, to provide cashflow during the drought and to support community centred natural resource management (NRM) works.
The main objective of the program was to provide employment for drought impacted community members in need. The program eligibility was extended to include bushfire impacted individuals following catastrophic bushfires in East Gippsland in 2019/20.
