Restoring the Balance: Understanding and Defining Ecosystem Restoration

With the growing awareness of the importance of ecosystem restoration both to support broader ecosystem services and more directly to protect Australia’s emerging multi-billion-dollar nature-based tourism industry, there has come a need to better understand and define ecosystem restoration. Historically, vegetation management products and practices have been refined for a specific market and purpose with the view that they can be implemented in a highly controlled environment. Quite often these controls are focused on the establishment and maintenance of monocultures or simplified polycultures that can be controlled through a highly refined set of management interventions that are not necessarily conducive to effective restoration for ecosystem diversity. Effective ecosystem management means applying these existing vegetation management products and practices in new and innovative ways that can better foster biodiversity. 

Bush Regeneration vs. Turf Management
Bush regeneration focuses on restoring native ecosystems, while turf management is primarily concerned with maintaining healthy, aesthetically pleasing monocultural lawns. By design, a turfed area has very limited biodiversity. Turf management involves regular mowing, fertilizing, and pest control to ensure a uniform and consistent set of conditions that favor a single species over all other species and vegetation strata. In contrast, bush regeneration emphasizes the restoration of all strata (ground covers, shrubs, and trees), removal of invasive species, and the reintroduction of native plants to create a self-sustaining ecosystem that should require less and less regimented management over time. The primary goal of bush regeneration is to enhance biodiversity, whereas turf management prioritizes the visual appeal and usability of grassy areas to the exclusion of biodiversity.

Bush Regeneration vs. Landscape Gardening
Landscape gardening involves designing and creating aesthetically pleasing outdoor spaces, often incorporating a limited polyculture mix of native and exotic plants, hardscaping elements, and decorative features. The primary objective of landscape gardening is to enhance the visual appeal and functionality of a space, whether it be a residential garden, public park, or commercial property. Aesthetics take precedence over natural functionality or diversity. Although likely less than that required of high-quality turf, a regimented management system of fertilizing, mulching, pruning, and pest control is likely to be required. In contrast, bush regeneration focuses solely on restoring and preserving native ecosystems. While both practices may involve planting and maintaining vegetation, bush regeneration prioritizes ecological health and biodiversity over aesthetics.

Bush Regeneration vs. Infrastructure Management
Infrastructure management has the sole focus of ensuring biodiversity of any kind cannot interfere with or damage key infrastructure, requiring vegetation management to focus solely on asset protection. In these instances, bare earth management approaches are often the objective, and the complete removal of natural biodiversity processes may be the specific goal. The primary goal of asset management is to ensure the long-term sustainability and usability of these assets for the benefit of the community. This may involve regular maintenance, infrastructure development, and resource allocation. Bush regeneration, on the other hand, is specifically focused on restoring and preserving native ecosystems. While infrastructure management may include elements of bush regeneration, its broader scope encompasses a wide range of activities aimed at maintaining and enhancing public assets.

Bush Regeneration vs. Primary Production
Primary production refers to the agricultural practices involved in producing food, fibre, and other raw materials. This includes activities such as farming, grazing, and forestry. The primary objective of primary production is to maximize yield and profitability, often through the use of intensive farming techniques, chemical inputs, and monoculture crops, often to the detriment of surrounding natural systems. In contrast, bush regeneration aims to restore and maintain native ecosystems, promoting biodiversity and ecological balance. While primary production focuses on economic outcomes, bush regeneration prioritizes environmental health and sustainability.

Implications for Bush Regeneration
The long-held view in Australia that bushland is unproductive has meant significantly lower investment in research and development of management practices for bush regeneration compared to turf, landscaping, asset management, or primary production. Though various government agencies have tried to address this in recent years through fact sheets, best practice guides, and the issuing of off-label permits, there are still significant limitations in terms of registered products for use in natural areas, particularly for new and emerging weeds and pests. The challenge for bush carers and the agricultural chemical industry as a whole is to collaborate and adapt these existing products and research into the context of natural areas to develop new and innovative ways to combat weeds and preserve Australia’s unique and valuable landscapes.

Bush regeneration stands as a critical environmental practice dedicated to restoring and preserving native ecosystems, with a strong emphasis on biodiversity and ecological health. While it shares some techniques with turf management, landscape gardening, asset management, and primary production, its objectives and approaches are distinct. The primary challenge lies in fostering a broader recognition of the value of bushland and securing the necessary investment and innovation to support effective restoration efforts. By doing so, we can ensure the sustainability and resilience of Australia’s unique natural environments for future generations.
