The First 25 Years
Since Aranovus Limited was established in 1988, we have accumulated over 25 years of experience with a diverse range of natural resource management projects the length and breadth of New Zealand.
Environmental science, natural resources & sustainability.
Since 2003 we have operated as 'Aranovus Limited'. Our project portfolio has doubled in number and projects have grown in size and complexity to the largest now exceeding $2 million.
Our core natural resource management work has continued to grow, augmented with more sophisticated environmental assessment and monitoring, especially for water quality. We now provide multi-parameter water quality metering and photometric analysis of water samples. Our expanded premises have allowed the development of laboratory space for field sample analysis and light microscopy for environmental investigations, especially estuarine sample analysis and macroinvertebrate identification.
Our investigation and advice services have significantly expanded and now include international clients requiring natural resource management input to commercial developments being planned in New Zealand. We have also undertaken significant socio-environmental research projects, including on a national scale, to generate robust information about how people, as resource users, and their communities interpret and respond to environmental issues. This expanding field lies at the core of natural resource management as we move through our third decade of operations.
1997 - 2002
Ecological restoration, pests & planting.
Between 1997 and 2002 we operated as 'Applied Ecology' after Marie McEntee joined Grant as a partner. Building on our extensive wetland experience, we expanded our work to include the design and delivery of ecological restoration projects. The diversity and size of projects markedly increased to include environmental assessment, predator management, forest restoration and revegetation, sometimes in combination with wetland restoration. This took us as far afield as the Chatham Islands.
Our pest and predator projects expanded to deal with the management of nuisance birds and mammalian predators. This included large scale fauna assessments and long term control programmes.
Wetland projects were completed for private clients and on Tiritiri Matangi Island, the Department of Conservation's most successful open sanctuary. Major wetland projects were undertaken in Northland and near Taupo where we restored a highly degraded oxbow wetland system with the construction of a water management system we designed and built. These projects often included large scale revegetation. For DoC we also developed an ecological strategy for Mokoia Island in Lake Rotorua and drafted the national captive management plan for weka.
Our expertise was used by clients as an expert witness and to audit projects designed by others. We appeared in the Environment Court and before planning hearings to provide expert evidence about the effects of proposed developments in sensitive environments and how these could be mitigated. We also began providing clients with independent peer reviews of proposed projects to improve design outcomes.
1988 - 1996
Wetlands, waterfowl & threatened species.
Aranovus was established by Grant Dumbell as 'Ecologic Consultants'. Between 1988 and 1996 the focus was wetland restoration and threatened waterfowl conservation. Grant worked closely with the Department of Conservation and oversaw the national captive management projects for two of New Zealand's rarest waterfowl, the brown teal (pateke) and the blue duck (whio). He wrote the national brown teal recovery plan and the national captive management plan for brown teal.
Grant also worked with the QEII National Trust to conserve and manage large protected wetlands in Otago and the Wairarapa. He was instrumental in the establishment of CMaG the New Zealand Conservation Management Group, an umbrella group for all threatened species captive management carried out by zoos and wildlife parks throughout the country. Grant served as Secretary and Chairman and is now a Life Member.
Grant also helped establish the New Zealand Waterfowl and Wetlands Trust to financially support wetland conservation in New Zealand and he served as Secretary and Trustee. He visited Canada, the United States, Britain and Australia to work with some of the world's most effective wetland conservation organisations, including Ducks Unlimited Canada and The Wildfowl and Wetlands Trust. Working with The Wildfowl and Wetlands Trust he was the New Zealand link for the establishment of 'Wetland Link International', a global network of wetland education centres that promote wetland conservation.
