The council started a survey earlier this year of existing areas of significant nature conservation value (ASCV) that could be deemed SNAs.
Council compliance and development group manager Jane Donaldson said the move came in anticipation of the National Policy Statement for Indigenous Biodiversity (NPSIB), which has recently come into force.
This policy statement directed councils to have consistent approaches in their policies, plans and strategies to maintain indigenous biodiversity.
“The survey is currently an audit of existing SNAs, referred to as ASCV’s, but it also has crossover with council’s responsibilities under the NPSIB, and also council’s draft biodiversity strategy.”
The process of identifying SNAs is still under development, with the council required to identify SNAs by 2028, Donaldson said.
It is unknown how many landowners in Mid Canterbury are likely to be affected, she said.
“It is expected that affected owners will initially be contacted individually”.
So far five letters have been sent out, Donaldson said, noting that some additional land was within the conservation estate.
A copy of a letter to affected property owners provided by the council outlined how it was undertaking an initial assessment of the existing ASCVs and “has discovered some areas where further investigation is needed”.
“In some cases, this might be because of vegetation change, but in others, it might be because of errors in the initial creation of the overlay maps.
“There is the possibility that these might be creating unnecessary regulatory hurdles or risks for farming operations,” the letter stated.
The letter also explained that due to the NPSIB, the council “may have to take a district-wide look at biodiversity” to ensure its existing mapping is correct and accurate.
The preference is “for this to be a collaborative project between council and landowners”.
Eventually, a Resource Management Act process would need to be followed to seek any changes in the District Plan, Donaldson said.
The District Plan, adopted in 2014, has provisions regarding ASCVs – listing 67 sites across the district, but the current project and related work may result in changes, Donaldson said.
“But these are yet to be developed and would also require a Resource Management Act process to be considered.”
Local iwi have been briefed and approached for discussion about involvement in the process, but those discussions are yet to occur, Donaldson said.
What is an SNA?
Significant Natural Area are considered to be areas of New Zealand’s most important remnants of native habitat that must be protected to ensure the ongoing biodiversity of the country.
The Resource Management Act (RMA) 1991 requires that they are protected.
It refers to “the protection of areas of significant indigenous vegetation and significant habitats of indigenous fauna” - or SNAs.
The term ‘significant’ is not defined by the Resource Management Act, and its ambiguity has resulted in confusion among resource managers and users, as well as national disparity in approach to the identification of SNAs.
Councils around the country are responsible for identifying SNAs in their territory, and because of that issue around “significant”, each council can apply different standards when assessing SNAs.
Part of the public concern about SNAs is that most are on private land, and those who own that land are worried about losing it, or the land itself losing its value and adding complications for owners.
Existing practices in or near SNAs will generally be able to continue, but restrictions will apply if a landowner wants to use the land for a new activity, and therefore needs to apply for consent.
