Pest Management Changes Proposed for Hawke’s Bay
Changes to the way pest management is approached in
Hawke’s Bay are in the Proposed Regional Pest Management
Plan 2018-2038 which has been approved for consultation by
Hawke’s Bay Regional Council.
The proposed plan has been developed by Regional Councillors and staff working with key stakeholders and interested groups, including the horticulture and agriculture sector, Department of Conservation, council, iwi and members of the community. The current pest management strategies were reviewed and changes made to meet new demands and legislative requirements.
The Proposed Regional Pest Management Plan is open for public consultation from 2 February to 16 March 2018. Accompanying the proposed plan is a cost benefit analysis and cost allocation report.
A discussion document was issued in May 2017 seeking feedback on pest management and highlighting key proposals for change. Over 90 submissions were received on the discussion document which has helped shape the proposed plan.
“Our Pest Management Plan is hugely important to the region, delivering both economic benefit to farmers and advancing our biodiversity goals,” Cr Tom Belford, Chairman of the Environment and Services Committee.
Submissions from both urban and rural people are welcome before the consultation period closes on Friday 16 March 2018. People who submitted on last year’s discussion document are being approached directly to request their further input.
Major changes in the proposed
plan are -
• Inclusion of marine pest
management programme. Since 2009, the number of
non-indigenous species in New Zealand has risen by 10
percent, with 33 new species recorded between 2010 and 2015.
Currently there are only two known marine pests in Hawke’s
Bay: Asian kelp (Undaria pinnatifida) and Australian
tubeworm (Ficopomatus enigmaticus). A marine rule
has been added to the plan requiring all vessels entering
Hawke’s Bay waters to be clean of biofouling to prevent
these pests becoming established. Hawke’s Bay Regional
Council staff recently cleared a reef build-up of Australian
tubeworm in the Ahuriri Estuary that was affecting tidal
flow and biodiversity.
“It is a lot more cost effective
to attempt to prevent invasive species entering our region
than it is having to control them,” says Cr Belford.
• Reduction of the catch trap (RTC) rate in
Possum Control Areas from 5% to 4%. That is a measure of
the number of possums trapped in monitoring runs – the aim
is to have only 4 traps in 100 or fewer catching a possum.
This is a reflection of the success of the regional possum
control area programme in continuing to keep possum numbers
low.
“We are currently tracking at 2.5% across the
entire possum control area programme which is a huge
success. Reducing the RTC will help detect problem areas
faster and is heading in the right direction for Predator
Free Hawke’s Bay,” Cr Belford.
•
Addition of a ‘good neighbour’ rule for possums,
matching the trap catch rate change. Possums will need to
be controlled to 4% RTC within 500m of a boundary of a
neighbouring property where a possum control operation is in
place.
• Addition of another ‘good
neighbour’ rule for feral goats. This requires
responsible management of goats within 500m of a
neighbouring property where that property is actively
managing feral goats to protect native plantings or
biodiversity values. In Hawke’s Bay, feral goats are
considered a pest but are also managed as an economic
resource so the plan takes a balanced, pragmatic approach to
landowners’ needs.
“Feral goats represent a major
threat to the increased riparian planting and afforestation
initiatives that are being contemplated for the region.
Councillors are treating this as a high priority,”
emphasised Cr Belford.
• Addition of
wallabies as an exclusion pest. These are found in
neighbouring regions.
• Addition of 6 pest plant
species to an exclusion programme, with the aim of
preventing them establishing in the Hawke’s Bay region -
Noogoora bur, Yellow bristle grass, Alligator weed,
Marshwort, Senegal tea, Spartina. These are currently not
found in Hawke’s Bay. Cathedral bell and Darwin’s
barberry which are in the region have also been included in
the plan for the first time.
