Gisborne District Council Erosion Management – initial capacity building work

The Gisborne district has severe erosion problems, with 26% of the land being susceptible to severe erosion, compared with only 8% of the rest of New Zealand.

This programme is helping address the district's severe soil erosion issue by building the council's land management capability and expertise. This work will pave the way for future land treatment work.

Funding is targeted to:

• investigate the use of debris dams or other methods to control highly erodible gullies
• employ a GIS (geographic information systems) analyst to create a comprehensive spatial dataset that identifies what erodible land has and hasn’t been treated, and helps provide data to make decisions about the best ways to protect that land from erosion, especially where current methods aren’t suitable
• employ a Senior Strategic Sustainable Land Use Advisor to assess opportunities presented by the One Billion Trees Fund and other funding initiatives, so that programmes that best meet the sustainable land use needs of Tairāwhiti (Gisborne) are identified and implemented.

MPI also supports wider erosion control work in Gisborne through the Erosion Control Funding Programme .

Sustainable Hill Country and Regional Priorities (SHARP)

Northland has major erosion issues, with over 60% of the region and 40% of the region’s pastoral (grazing) land classified as highly erodible. Deforestation of land has led to extremely high levels of sediment in streams, lakes, harbours and coastal systems.

Before SHARP funding, it’s estimated it would have taken 30 years to complete Farm Environment Plans for the 5,000 farms identified by the Northland Regional Council as having highly erodible land under pasture. 

The funding for SHARP is helping deliver:

• farm planning
• increased engagement with landowners and communities
• accelerated implementation of land treatments on highly erodible land, including
  • afforestation (exotic and native tree planting)
  • soil conservation planting
  • land retirement and assisted regeneration
• building capacity and capability of local planting contractors and partner agencies.

Sustainable Land Use Initiative (SLUI)

In 2004, a storm that struck the Manawatu, Rangitikei, Wanganui, and Tararua Districts caused erosion in the hill country and flooding, sedimentation and stream course changes in the lowlands. Damage is estimated to have cost over $300 million. Unsustainable land use of hill country was a major factor that contributed to this damage.

Over half the land in Manawatu-Whanganui is classified as hill country. SLUI aims to reduce erosion and build resilience to weather events in the region, protect downstream communities, extend the life of flood protection assets, and improve water quality in the region.

Funding is helping the SLUI programme to:

• produce whole farm plans for 90,000 hectares
• implement 13,665 hectares of erosion control and sediment control works
• establish 6.82 million trees or 1.7 million per year.

Nelson Hill Country Stabilisation Project

Heavy rain events, like the 2011 storm that caused multiple slips in the Nelson region, are likely to become more frequent and intense as the climate changes. This programme is helping mitigate future damage by stabilising and protecting erosion-prone land, focusing on erosion on forestry land or post-harvest forestry land.

Funding is being used for the:

• development of 40 Forestry Environment Plans
• land reversion and native forestry planting of high-risk sites on farming and forestry land, contributing toward 200,000 trees across the four years
• engagement and collaboration with iwi as major forestry landowners – working with other Top of the South councils
• development of long-term strategies and specific plans for erosion control.

Southland Catchment Erosion Programme - initial capacity building work

Southland has more than 100,000 hectares of highly erodible land at risk of erosion.

This programme is working to:

• develop a strategic approach to erosion control at a regional level and a longer-term work programme for intervention
• build the Council’s capacity to plan for and prioritise erosion and sediment management by employing someone in a one-year fixed term position
• pave the way for future programme of engagement with landowners and land treatment work.

South Taranaki and Regional Erosion Support Scheme (STRESS-3)

In Taranaki, the regional council estimates an extreme storm event causing flooding and slips will occur about once every five to six years. Studies show that compared to pasture, 90% less erosion and slippage occurs under bush/forestry plantation, 80% less under scrub cover and up to 70% less where soil conservation trees are planted.

This project builds on the last nine years of successful STRESS programmes, which have so far treated around 7,000 hectares of erodible land with 4,062,000 trees. An estimated reduction of 700,000 tonnes of sediment per square km/year has resulted from these programmes.

This funding is helping to:

• establish of 770 hectares of exotic/Manuka forestry
• establish of 167 hectares of native reversion/native planting
• complete 3,500 hectares of new farm plans
• grow and plant 12,000 poplar poles
• extend the area of land to grow more poplar poles
• increase staff capacity to deliver the programme.

Restoration and Resilience – Marahau Catchment Reversion in the Wake of Disaster

In 2018, ex-Tropical Cyclone Gita slammed into the Tasman district, and the intense rain that arrived with it caused multiple slips across the district. One area particularly affected was on plantation forestry land behind Marahau, which was returned to iwi in 2014 as part of a Treaty settlement.

Part of this programme is delivering a small pilot project to address the challenge of radiata pine forestry on Separation Point granite above Marahau. Core elements of the project are:

• a partnership between council and the iwi owners of the land, Ngāti Tama ki Te Waipounamu Trust and Ngāti Rārua Settlement Trust
• reversion of 114 hectares  of highly erodible land from forestry into permanent native cover
• use of the knowledge gained from this process to illustrate alternative land management for this type of land.

Funding has also enabled the provision of a shared land management role for the top of the South Island. The role is focused on forestry land and the issues that arise in the erosion window after harvest, especially in those areas that aren’t suited to forestry.
