Towards a framework for targeting national-scale, native revegetation in Aotearoa New Zealand’s agroecosystems

The incorporation of native, woody vegetation into New Zealand’s agricultural ecosystems offers a “nature-based solution” approach for mitigating poor environmental outcomes of land use practices, biodiversity loss, and the accelerating effects of climatic change. However, to achieve this at scale requires a systematic framework for scoping, assessing, and targeting native revegetation opportunities in a way that addresses national-scale priorities, supports landscape-scale ecological processes, and recognises that land use decisions are made at farm-scales by landowners.

Current knowledge and potential impacts of climate change on New Zealand’s biological heritage

While global climate change is impacting biota across the world, New Zealand’s maritime climate is highly variable and relatively mild, so climate change is sometimes seen as a minimal threat to species and ecosystems especially in comparison to the more immediate threat of invasive species. However, climate change will alter rainfall patterns, increase the incidence and severity of extreme events, and gradually increase temperatures which will all modify terrestrial, freshwater, and marine systems.

The biogeochemistry and ecological impact of Westland petrels (Procellaria westlandica) on terrestrial ecosystems

The Westland petrel (Procellaria westlandica) is a 1200 g medium-sized seabird whose breeding colonies are dispersed across 700 ha of forest on the western coast of South Island, New Zealand. These birds represent the sole landscape-scale lowland remnant of formerly widespread petrel and shearwater colonies in mainland New Zealand and provide an opportunity to investigate maritime species’ impact on terrestrial ecosystems characteristic of pre-human New Zealand.

The significance of sheep and beef farms to conservation of native vegetation in New Zealand

Relying solely on public conservation lands for habitat provision will be inadequate for achieving national conservation goals. Production landscapes in New Zealand make up 60% of the land area and contain potential conservation habitat; however, the amount of native vegetation they contain is poorly known. While there have been previous assessments of native vegetation cover in New Zealand, no study has undertaken a national-scale assessment of multiple native vegetation cover types on different land uses. This absence limits the potential to manage production landscapes for conservation.

Biodiversity monitoring, ecological integrity, and the design of the New Zealand Biodiversity Assessment Framework

The New Zealand Department of Conservation is responsible for biodiversity management over approximately one-third of New Zealand’s land area and a network of marine protected areas; it also has a more general role in managing protected species and biodiversity advocacy. In 2004 the Department of Conservation began the development of a national natural heritage monitoring framework known as the New Zealand Biodiversity Assessment Framework, which has been operational since 2011.

Achieving win-win outcomes for pastoral farming and biodiversity conservation in New Zealand

Pastoral farming is the dominant land use in New Zealand today and is under considerable domestic social and political pressure to reduce its environmental footprint. In this article, we explore options to enhance native biodiversity conservation within New Zealand pastoral systems. We argue that there is strong synergistic interdependence between biodiversity conservation and pastoral farming and suggest that it is possible to have win-win outcomes for both.

The ecosystem commons

Kei te ngaro haere ngā tohu taiao o Aotearo o te ao whānui hoki, pēnei i te wai ora. Ko te mate hoki kāre e āro ana te tangata me pēhea e whakatika, mā wai, me pēhea e whakarite, ka patua tonu. I te tau rua mano tekau ma iwa ka whakaetia te Kāwanatanga me tū te awa o Whanganui hei tangata i raro anō i tōna ake mana. Ahakoa he mea rerekē tēnei ki te ao Pākeha, ehara ki tō te tikanga Māori. Ko te kaupapa o tēnei tuhituhi he pātai mena koianei te huarahi, ina ra te whakatangata i ngā tohu taiao kia rite ai ki te ture Pākeha, kia ngāwari ake te whakatikatika haere.

More than a ‘nice to have’: integrating indigenous biodiversity into agroecosystems in New Zealand

Globally, biodiversity is declining due to increasing populations and land use pressures associated with development-induced land conversion, resource use, and food production. In New Zealand, a considerable proportion of remaining indigenous biodiversity occurs on farmland in private ownership outside of the public conservation land.

Do local landscape features affect wild pollinator abundance, diversity and community composition on Canterbury farms?

Pollination is an essential ecosystem service that can be affected by habitat features in the immediate environment, termed here ‘local landscape features’. This study tested how five local landscape features (bare ground, native biodiversity plantings, homestead gardens, shelterbelts, and control areas of pasture) affect local pollinator communities on Canterbury farms. We also compared two sampling methods (flower visitation to native potted plants vs sticky traps) to determine if the sampling method affects the results of landscape-feature comparisons.
