Remediating the land.

Red Tree’s approach provides science-based, prescriptive solutions to the environmental challenges we collectively face. Drawing on innovative technologies and extensive horticultural experience, we are working with government agencies, councils, landowners and Iwi to restore native ecologies across Aotearoa.

Biodiversity and Catchment Scale Restoration

We collaborate with various agencies to restore extensive landscapes to their former ecological glory. With a focus on regional parks, retired farmland, and riparian margins, our holistic approach integrates multiple methods to successfully restore native ecologies, create bird corridors, and sequester carbon.

Through strategic partnerships with Iwi, civic clients, private landowners, and government agencies we deliver restoration projects that transcend regulatory and compliance standards.

Utilising cutting-edge drone technology, we ensure precision in pest identification and post-installation reporting, generating detailed maps of project sites for enhanced monitoring and evaluation.

By transforming marginal land into thriving ecosystems and carbon sinks, we not only mitigate erosion and sedimentation but also preserve indigenous species and protect our valuable waterways. These efforts contribute to the overall enhancement of our natural environment and sustainability initiatives, safeguarding our ecological heritage for future generations.


Wetland Establishment

Wetlands are vital for providing regulating and supporting ecosystem services - they are the hardest working ecologies.

Wetlands provide flood management, erosion control, water purification, nutrient cycling, wildlife habitat, healthy soils, cultural significance, recreational value, and aesthetic beauty.

With relatively simple engineering, low lying water retaining zones previously drained for agriculture purposes, can be restored to vibrant and biodiverse wetlands, detention/retention basins within 2-3 years time.

Whether you are working with 60 or 60,000m2, the principles of biomimcry remain constant and deliver consistent results.


Motorway Landscaping

Motorway landscaping projects are of considerable scale, demanding efficiency and capability in the allocation of time, resources, and labour.

Time management, co-ordination with other contractors, boots on the ground, and robust health and safety processes are critical.

Red Tree has a proven track record of delivering environmental projects of scale, with high cultural significance, and alongside road and rail.


Aerial Mapping and Monitoring

At Red Tree, we offer aerial mapping and monitoring services, using advanced drone technology to provide comprehensive insights into any environment. Our approach involves collecting and processing RGB, multispectral, and thermal data, enabling us to delve deep into various aspects of terrain and ecosystem health.

Through aerial mapping and monitoring, we reveal invaluable information regarding topography, chlorophyll levels informing of plant health and growth, hydration patterns, precise plant identification and counts, and pest identification.

Utilising photogrammetry techniques, we seamlessly stitch together aerial photographs to create detailed representations of landscapes. This process facilitates the generation of digital elevation models and digital surface models, offering comprehensive understandings of terrain features and ecological dynamics.

Our expertise extends beyond data collection, encompassing interpretation, analysis, and actionable recommendations. By distilling complex data into actionable insights, we empower stakeholders to make informed decisions regarding environmental management and conservation efforts.


Land Stabilisation

Following a weather event, natural disaster, or significant erosion period, timing is critical and direct seeding provides a rapid response to stabilise the land. Direct seeding native species has the additional benefit of restoring biodiversity and adding to the depth of stabilisation.

Drones allows immediate response and access to slip sites and removes risk to personnel.

Creating native seed banks in high risk regions is a strategy we promote to regional councils. Seed mixes are prescriptive and dependent on the substrate.

Traditional cereal grain species can be incorporated into seed mixes to achieve rapid germination (12-15 days) fix nitrogen and attract bird life.

Seeding ratios and outcomes is a constant R&D focus for Red Tree and the technique of spreading seeds then applying a binding material such as organic polymer or clay to the top layer of soil to prevent surface erosion is one we have refined over the past five years.


Vegetation Management

In addition to being a key component of all ecological restoration projects, Red Tree offers vegetation management services for fire risk management and pest plant biosecurity.

The key principle behind vegetation management is the understanding and management of pest plant competition with emerging native succession in plant communities.

Pest plant species metabolise exponentially faster than native species. Therefore, the management process begins with monitoring and observation so the most appropriate control methodologies can be employed.

Red Tree is incorporating specialist drone technology with its multispectral mapping capabilities and targeted delivery systems, alongside traditional control methods of hand and mechanical releasing of the plants.

This facilitates greater insight into site conditions, precise application, and versatility in accessing challenging sites.

Red Tree is a certified CAA 102 licence holder and operator, and all pilots hold the appropriate agricultural chemical ratings.
