Link Seminars
In the past we have also hosted in-person seminars for environmental policy-makers in Wellington. PDF presentations are available on the Link Seminars page on our website.
Revision of soil quality indicator target ranges
Presenter: Dr Jo Cavanagh
Date: Thursday 3 April
Time:11:00 - 11:30 am
Soil quality indicators have been used in State of the Environment (SoE) reporting for the past 20+ years and cover several soil characteristics important for predicting agronomic performance and environmental impacts (eg, macroporosity, Olsen P). Provisional target ranges for soil quality indicators were published in 2008. While there has been review and some revision to target ranges, a substantial amount of additional soil monitoring, reporting, and research has been undertaken since the provisional target ranges were set.
Mitigating Greenhouse Gas emissions from drained peat
Presenter: Dr Jack Pronger, Manaaki Whenua – Landcare Research, and Dr Louis Schipper, University of Waikato
Date: Tuesday 8 April
Time:11:00 - 11:30 am
Natural peatlands are large carbon stores that have accumulated over thousands of years because waterlogged conditions have slowed decomposition. These soils can be highly productive when drained for agriculture, but the land surface subsides, and accelerated decomposition results in CO2 and N2O emissions. In NZ, this decomposition produces about 7% of national net greenhouse gas (GHG) emissions with some uncertainty as there are very few NZ-specific measurements.
Ecological impacts of Cyclone Gabrielle
Presenter: Dr Warwick Allan
Date: Tuesday 10 June
Time:11:00 - 11:30 am
In mid-February 2023 Cyclone Gabrielle struck the North Island of Aotearoa New Zealand, causing widespread destruction. As part of the cyclone response, Manaaki Whenua – Landcare Research partnered with NIWA, mana whenua, regional councils, and other stakeholders to assess the impacts of Cyclone Gabrielle on native ecosystems, from forests and wetlands to rivers and coastal dunes.
