Ecological Restoration

 

Ecological restoration is the process of assisting the recovery of an ecosystem that
has been degraded, damaged or destroyed
(SERA 2021: 26).

The goal of ecological restoration is full recovery, insofar as possiblein some cases, constraints
may limit potential to less than full level of recovery. Such cases can still be referred to as
ecological restoration projects as long as the aim is for substantial recovery relative to the
appropriate local native reference ecosystem (SERA 2021: 14).

The ethic of ecological restoration is one of conservation, repair and renewal…ecosystem restoration seeks to not only compensate for damage and improve the condition of ecosystems but also to substantially expand the area available to nature conservation (SERA 2021: 2).

Dispossession of First Nations communities in Australia and the United States of America (USA) was accompanied by extensive settler mismanagement and degradation of unique natural ecosystems. In the early decades of the twentieth century, the idea of repairing degraded ecosystems developed; desire to conserve valued indigenous biodiversity was one compelling reason (Jordan III, Lubick 2011: 2, 38-43).

Ecological Restoration presents a series of historical Australian degraded area repair projects that featured principles and standards of contemporary ecological restoration practice (see SERA 2021).

Two conservation focused but unsuccessful 1930s repair projects

The earliest known and successful Australian degraded area repair projects that extensively featured practices and ideals comparable to contemporary ecological restoration practice commenced in 1935 and 1936. However, at least two strongly conservation focused, but ultimately unsuccessful, Australian environmental repair projects preceded them; perhaps there were more.

Biologist David Stead was a determined campaigner for the conservation of indigenous biota, and founded the Wildlife Preservation Society of Australia in 1909. He launched an attempt in ca.1930 to restore to the state of New South Wales (NSW) the much slaughtered Australian koala (Phascolarctos cinereus), a tree climbing herbivorous marsupial, often referred to, rather inaccurately, as a bear or the native bear. Although historically interesting, unfortunately ongoing disputes over methodology and finances troubled the project, and led to its ultimate demise. Details of the actual project are sparse, but it is quite likely that Stead would have aspired to extensive reinstatement of the koala to its natural range in New South Wales, had his project proceeded.

In 1931 distinguished entomologist Walter Froggatt recruited North Sydney Council, New South Wales, and launched a degraded area repair project at Balls Head reserve, Sydney Harbour. The reserve is located within the homelands of the Eora nation. Members of this nation were dispossessed following the British invasion of Sydney in 1788; introduced diseases such as smallpox decimated communities.

Froggatt outlined ambitious ecological objectives for his restoration project. He aspired to the creation of a ‘home for the trees, flowers and birds of old-time Sydney Harbour’ (Ardill 2021). The regional Hawkesbury sandstone flora served as a model to guide the revegetation work. Today, this form of model is referred to as an ‘indigenous reference ecosystem’ (SERA 2021: 4).

Plant surveys, replanting and other restoration work were undertaken. However, following Froggatt’s death in 1937, the project dissolved into sporadic landscaping and beautification events, involving non-regional flora species (Ardill 2021).

Froggatt was a member of David Stead’s Wildlife Preservation Society of Australia, and maybe the two men discussed their respective repair projects. It is also interesting to note that at the same time that Froggatt was working on his Balls Head repair project, he was also campaigning to prevent the release in Australia of the Cane toad Rhinella marina, to serve as a biological control. Froggatt’s efforts were unsuccessful, and today the poisonous toad poses a significant threat to many indigenous animal species.

Arid lands restoration, South Australia, ca.1930

Ecologically focused restoration of degraded South Australian arid-zone vegetation communities can be traced to approximately 1930. Aspiration to restore a high level of indigenous vegetation integrity was exhibited, but details about other aspects of the various projects, such as the levels of stakeholder engagement, the conservation outcomes achieved and surveys of the restored plant and animal species, appear to be unavailable.

Following the British parliament’s formal 1834 establishment of the new colony, South Australia, and the 1836 proclamation of the capital, Adelaide (also known by its First Nations name, Tarntanya), the forced dispossession of First Nations communities was effected by settlers supported by military forces. Government legislative and social oppression of these communities continued for many decades.

By approximately 1870 a pastoral industry featuring primarily sheep and also cattle had been established in the central and north-eastern arid-zone regions of the colony. Inappropriate land management practices, largely of European origins, and exploitative stocking rates were prominent features of the new industry. Degradation of the indigenous vegetation soon followed. Stripped of protective cover, soils were eroded by regular winds, and massive sand-drifts and scalded plains became widespread throughout the arid regions.  

From approximately 1920, University of Adelaide botanist and plant ecologist Dr T G Osborn observed and conducted extensive research into the disappearance of the arid-zone indigenous vegetation. Concluding that overstocking was the prime cause of vegetation loss, he advised pastoralists to carefully manage stocking levels on their properties. At the university’s Koonamore research centre, Yunta, the application of stock exclosure (fencing to exclude stock) and natural regeneration (germination of soil stored seed) techniques and concepts demonstrated that the arid-zone indigenous vegetation could be restored, in the presence of favourable ecological and land management conditions.

Pastoralists concerned by loss of vegetation on their properties and the resultant wind erosion undertook indigenous vegetation restoration projects. Although not directly confirmed, it is quite likely that they were informed by Osborn’s research and his revegetation techniques. At Wirraminna station, north of Port Augusta, owners George and Dick Jenkins developed ‘flora reserves’ which utilised stock exclosure and natural regeneration processes to successfully restore indigenous vegetation to soil-drifts and stabilise them (Ardill 2022: 20). The Jenkins brothers appear to have aspired to substantial, and possibly even full restoration of the vegetation, but little other detail is known about their flora reserve projects (Ardill 2022: 61).  Flora reserves were also developed on other South Australian arid-zone pastoral stations throughout the 1930s.

South Australian pastoralists also engaged in the furrowing of eroded areas, with the intention of restoring the protective indigenous vegetation by facilitating natural regeneration of naturally distributed, soil stored seed (Ardill 2022). At Melton station, manager Walter Smith, encouraged by Koonamore researcher Terrence Paltridge, initiated a furrowing project on a wind exposed soil-drift in ca.1930, and by 1939 substantial regeneration of the indigenous vegetation had been achieved. Furrowing of soil-drifts and scalded arid lands had become a widespread restoration practice in South Australia by ca.1940 (Ardill 2022).

The success of these revegetation projects was noted and applauded by prominent scientists such as Dr A E V Richardson, an executive member of the national Council of Scientific and Industrial Research, influential Adelaide newspaper editors, government administrators and legislators. Desperate to protect the state’s pastoral industry, in 1936 the South Australian government of premier Richard Butler endorsed stock exclosure, natural regeneration, furrowing and environmentally sensitive stocking practices as official state restoration policies. Financial aid was offered to pastoralists who wished to regenerate eroded lands on their stations. Additionally, these policies were codified in a new state Soil Conservation Act 1939 (Ardill 2022).

Restoring the Big Scrub, Lumley Park, Alstonville 1935

The highly biodiverse vegetation community, Lowland Rainforest of Subtropical Australia, once flourished for hundreds of kilometres along the coast and hinterlands of southern Queensland and northern New South Wales (OEH 2019). From approximately 1830, timber loggers, and then farmers, progressively expanded into these regions. First Nations communities, including the Bundjalung nation of present-day Alstonville and the broader Lismore region, were forcibly dispossessed of their homelands.

The settlers cleared the Lowland Subtropical Rainforest, primarily to enable dairy farming and other agricultural pursuits. Only scattered remnants remained by the 1930s.

On the north coast of New South Wales, Alstonville dairy farmer Ambrose Crawford, alarmed at the looming extinction of the rainforest community (or Big Scrub, as it was locally referred to), mustered strong community support for a rainforest repair project. Regional Tintenbar Shire Council approved and financially supported the project.

Work on a two hectares patch of remnant, highly degraded Big Scrub, known as Lumley Park, commenced in 1935. Guided by botanists and ecologists, Crawford carefully selected and replanted appropriate plant species, and weeded the exotic climbers and shrubs that infested the site (Lymburner 2018). As well as reversing the degradation, Crawford and his  small group of restoration colleagues also persevered with the conservation management of the restored rainforest for decades. Their legacy is significant, a rare and treasured stand of protected Lowland Subtropical Rainforest.

The successful repair and regeneration of other Big Scrub remnants has been undertaken in more recent times, commencing with Victoria Park Nature Reserve in 1978. These projects have been initiated and undertaken by coalitions of ecologically skilled and conservation minded local residents, regional rainforest advocacy organisation Big Scrub Landcare, government agencies and private landowners (Parkes et al. 2012)

Broken Hill regeneration area 1936

Pastoralists commenced seizing the Baaka (also known as the Darling River) and the extensive plains and low ranges of arid western New South Wales from approximately 1840. The First Nations communities of these regions, which included the Barkandji nation, were forcibly dispossessed of their homelands. Communities were confined to government reserves, frequently experiencing harsh conditions and ongoing discrimination (OEH 2021). For many decades strict state control over individuals and families was imposed by New South Wales state legislation, the Aborigines Protection Act 1909. After a protracted seventeen year administrative and legal process, the Barkandji, including the Wilyakali community of the Broken Hill region, were awarded Native Title rights to their homelands in 2015.

As was the case in South Australia, by ca.1900 vast expanses of the indigenous Atriplex spp. saltbushes and Acacia aneura Mulga vegetation communities of the west had become significantly degraded, predominantly due to pastoral industry overstocking practices. Constant exploitation of timber resources, plus exotic fauna species’ impacts (particularly rabbits and goats), also contributed to the destruction of the vegetation. Typical extended dry periods impeded vegetation recovery. Significant proportions of the regional landscapes, including the environs of Broken Hill, the main western New South Wales city, had been reduced to barren, eroded wastes by the 1920s (Ardill 2017).

Due to the degradation of the indigenous vegetation communities, sand-drifts and dust storms afflicted the residents of Broken Hill for many years. Albert Morris, a mining assayer and resident of the city, was determined to address this issue, by restoring a protective cover of indigenous vegetation that would stabilise the soils.

However, it is well documented that Morris closely studied and delighted in the evolved biological qualities of the regional ecosystems, and this factor also strongly motivated his interest in their restoration. He was distressed by the degradation of the beautiful arid landscapes, the widespread loss of indigenous plant communities and the resultant indigenous fauna extinctions. He also perceived the need to reform the environmentally unsustainable pastoral industry (Ardill 2017).

Acquiring considerable expertise as an arid-zone botanist, Morris studied and trialed various environmental repair techniques in the 1920s and 1930s. It is highly likely that he was considerably influenced by the 1920s restoration research work conducted at Koonamore research centre, South Australia, by plant ecologist Professor T G Osborn (see the earlier entry ‘Arid lands restoration, South Australia, ca.1930’).

Confronted by a conservation management vacuum, in 1936 Albert Morris initiated the Broken Hill regeneration area project, another historical Australian degraded area repair project that featured many of the standards and techniques of contemporary ecological restoration practice. The regeneration area project successfully utilised a stock exclosure technique and natural regeneration processes (not irrigation and planting, a common misunderstanding) to restore a wide range of the local indigenous flora species to hundreds of hectares of wasted terrain around western Broken Hill (Ardill 2017). Residents and government officials were amazed by the dramatic revegetation outcomes. Threatening soil-drifts were stablised. From 1939 botanists, ecologists and wind erosion researchers studied the widespread natural regeneration of indigenous plant species fostered by the protective fencing (stock exclosure) of the degraded landscape.

Following Albert Morris’s death in 1839, his wife and conservationist Margaret Morris, and other Broken Hill field naturalists, campaigned for the completion of the regeneration area by promoting its botanical and amenity values. The final reserve was fenced in 1958, and the indigenous flora and fauna were formally conserved (see Gallery).

The regeneration area project strongly influenced the New South Wales government’s development of soil conservation policies and legislation that addressed the wind erosion problems of the arid western regions of New South Wales. In particular, Soil Conservation Service researcher Noel Beadle, appointed in 1939, was deeply impressed by the revegetation outcomes achieved within the regeneration area, and derived practical erosion management lessons from the project. State legislation passed in 1949 enabled the use of stock exclosure and natural regeneration programs in the west, and outlawed overstocking (Ardill 2022).

The historical record suggests that opportunities for the Wilyakali community, Traditional Owners of regional homelands, to consider engagement with the regeneration area project and repair homelands did not arise. Pearce (2017: 581) acknowledges the achievements of Albert and Margaret Morris and their environmental repair colleagues, but maintains that ‘The Regen portends a trend in ecological restoration to overlook Indigenous people, stories and local knowledge…’ 

The regeneration area, consisting of a series of fenced regeneration reserves, persists today, supported by Landcare Broken Hill, local field naturalists, and the broader community. The beautifully crafted film, ‘Renewal in the desert‘, presents a compelling visual account of the development of the regeneration area project.

Australian Alps ca.1960

The traditional lands of the Ngarigo and Walgal (or Wolgalu) nations embraced the high country alps and Monaro plains of south-east Australia. Settlers commenced seizing these lands in the 1820s, dispossessing the Ngarigo and Walgal communities and rapidly disrupting their traditional cultural practices; introduced diseases also devastated communities (Environment 2016). Over time, the grazing and burning activities of the settlers significantly degraded the alpine high country: severe erosion afflicted expanses of sensitive alpine bog and fen ecosystems.

The film ‘Snowy Hydro – Conservation in the Snowy Mountains’ vividly illustrates the erosion issues that had developed in the Snowy Mountains by the 1950s. The erosion management techniques portrayed in the film, although in many respects quite innovative,  sometimes involved the inappropriate use of introduced plant species. See  https://aso.gov.au/titles/sponsored-films/snowy-hydro-conservation-snowy/clip1/#

A need to manage the substantial sediment flows generated by the grazing induced erosion, by reinstating and preserving the unique alpine flora ecosystems, motivated the development of innovative ecological restoration projects. Generous funding for the projects was provided by the Snowy Mountains Hydro-electric Authority, which operated a series of hydro-electric stations and associated reservoirs in the alps; the storage capacity of the reservoirs was threatened by the sediment flows.

The initial repair projects commenced in approximately 1960 and were managed by ecologist Roger Good and the New South Wales Soil Conservation Service. Good and his colleagues aspired to the progressive reinstatement of indigenous biological diversity to the sites, and restoration of the alpine flora was a major priority (Good, Johnston 2019). With the flora and soil cover reinstated, flows of sediments into the reservoirs dramatically decreased.

Management of the Australian Alps repair projects passed to the New South Wales National Parks and Wildlife Service in the 1970s, and Good’s extensive ecological knowledge and environmental repair skills were retained; he also managed post 2003 bushfire recovery projects in the alps. A culture of professional Australian scientific expertise evolved throughout the course of the Australian Alps projects: alpine botany, alpine ecology, and restoration ecology (Good, McDonald 2016: 14-15).

Today, members of the Monaro Ngarigo community work with the NSW National Parks and Wildlife Service to manage the Kosciuszko National Park, which extends across the Australian Alps (ABC).

Tower Hill, Victoria 1961

Tower Hill, near Warrnambool, Victoria, is a place of great cultural significance and value for regional Traditional Owners and Custodians, the Eastern Maar nation.

At Tower Hill reserve, a state government funded project pursued the reinstatement of the indigenous flora and fauna to the highly degraded site. The environmental ideals of USA ecologist Aldo Leopold, active in the important 1935 University of Wisconsin Arboretum ecosystem reconstruction project, influenced the project.

A group of Warrnambool field naturalists and Victorian Fisheries and Wildlife Branch officers commenced replanting the reserve in 1961. The project appears to have aspired to the reinstatement of substantial, and possibly even all potential levels of ecological function to the site. The pre-degradation indigenous vegetation communities were investigated, replanted flora was propagated from locally collected seed, additional botanical advice came from Melbourne’s National Herbarium and re-introduction of the indigenous fauna was attempted. Two nineteenth-century items, a landscape painting and a travel guide book, served as additional repair guides.

The Bradley Method, Sydney ca.1960

From approximately 1960 sisters Joan and Eileen Bradley developed a keen interest in the management of the introduced flora species that were threatening the quality of their local indigenous bushland at Mosman, Sydney. They devised a comprehensive weed and degraded area treatment technique, that became known as the Bradley Method. Their technique made use of the potential of indigenous flora species to naturally regenerate and recover from degrading impacts (Bradley 1971).

The New South Wales National Trust took up the Bradley’s ideas in the 1970s and applied them to the repair of Sydney’s degraded bush areas (May 1996). The Trust undertook professional bush regeneration contract work, and offered training courses in the principles of the Bradley Method and bush regeneration to professional bush regenerators and volunteer bushcarers.

From ca.1980, an increasing number of Sydney’s local government councils commenced employing their own professional bush regenerators to manage weed affected bushland. Subsequently, councils also employed professional bushcare officers to guide the work of volunteer resident bushcarers and their bushcare groups.

Today, an extensive network of local government supported volunteer bushcare groups restores the degraded indigenous vegetation communities of Sydney and NSW, often utilising the principles of the Bradley Method, or regionally modified versions. Along with more recently developed environmental repair practices, and the science, restoration ecology, the Bradley Method informs professional bush regenerators and ecological restorationists engaged with rehabilitation and ecological restoration projects.

Wingham Brush 1980

Dispossession of the Biripi (or Birpai) People, Traditional Owners of the lands of the Manning River, mid-north coast New South Wales, commenced ca.1830. Settlers seized the rich alluvial plains of the river and introduced European modes of agriculture. The Biripi resisted; punitive expeditions were undertaken by the settlers, and massacres of the Manning River clans were perpetrated (Ramsland 2001: 26). The extensive Lowland Subtropical Rainforest community of the region was rapidly reduced to scattered remnants by the early decades of the twentieth century.

At Wingham, on the Manning River, nine hectares of rainforest survived. This patch of rainforest became known as the Wingham Brush, but unfortunately, weeds had established a firm foothold in the Brush by the 1920s. In 1980 local resident John Stockard, dedicated environmental repair colleagues, and the New South Wales National Trust commenced a lengthy, arduous and highly successful project to restore the Brush and ‘to keep the ecological processes going’ (Stockard, Pallin undated).

It soon became obvious to Stockard that innovative repair techniques would have to be devised in order to successfully manage the variety of exotic plant species, particularly the vines and climbing plants, that had overwhelmed the Brush (Stockard 1996: 432-436). The introduction of herbicide use, and the development of efficient and effective means of applying them, was one such innovation.

Today Stockard and his colleagues continue to maintain and advocate for the rainforest, known as the Wingham Brush Nature Reserve (Brodie 2018). The biologically diverse reserve is listed as a critically endangered ecological community by the Australian government, and as with many restored conservation sites, faces ongoing degrading impacts from a range of direct, on-site human behaviours, as well as from climate change and ongoing weed infestation.
