URGENT UPDATE: Cyclone Gabrielle has left a devastating mark on the North Island’s ecosanctuaries, with a new report highlighting the extensive damage just published in the New Zealand Journal of Ecology. The cyclone, which struck in February 2023, wreaked havoc on crucial conservation infrastructure, affecting biodiversity projects that are vital for protecting Aotearoa’s unique ecosystems.
The latest findings from ecologists Dr. Warwick Allen and Dr. Sarah Richardson at Manaaki Whenua – Landcare Research reveal that a staggering 91% of ecosanctuaries reported damage from strong winds, while 85% faced severe erosion. Flooding impacted 45% of these critical areas, and sediment deposition affected 36%. The implications are dire, as 63% of the ecosanctuaries experienced multiple impacts on their conservation activities.
Of particular concern, half of the ecosanctuaries with pest exclusion fencing suffered breaches, leading to rapid pest incursions in three out of five reported cases. This breach threatens the very survival of local wildlife, as invasive species like rats and stoats infiltrate the areas meant to protect native biodiversity.
According to interviews conducted with representatives from 65 ecosanctuaries, the damage has disrupted essential conservation activities including pest management and native species monitoring. The long-term effects could lead to reduced management efficiency and the loss of access to vital conservation areas.
Despite the extensive destruction, there is a glimmer of hope. Remarkably, there have been no reported local extinctions, and the ecosanctuary network is determined to rebuild. Staff at the Opouahi Kiwi Crèche in Hawke’s Bay faced severe challenges when slips killed two kiwi chicks and compromised pest fencing. After extensive trapping efforts, they are optimistic about restoring predator-free conditions.
“This resilience demonstrates the unwavering commitment of our conservation community,” said Dr. Allen. However, he warns that the increasing frequency of extreme weather events will continue to test these systems, underscoring the urgent need for adequate resources for ongoing protection of indigenous ecosystems.
As the region assesses the full scale of the damage, the call for support and action from local communities and authorities is louder than ever. Local conservationists emphasize the importance of collaboration to ensure that these ecosanctuaries can continue to provide refuge for Aotearoa’s threatened species and restore biodiversity.
Stay tuned for more updates as authorities work to address the recovery efforts and protect these critical ecosystems from future extreme weather events.
