This slidecase describes in photos and quotes the story of the Silverstream wetland and farm restoration undertaken by the Simpson family and the Canterbury Waterway Rehabilitation Experiment (CAREX). These slides accompany the manuscript "Partnerships generate co-benefits in agricultural stream restoration (Canterbury, New Zealand)".

Through the CAREX project, we have tested a series of practical tools, and developed solutions and approaches to address aquatic weed, sediment, and nutrient management issues in agricultural waterways in lowland Canterbury.We have developed a set of steps and toolboxes, underpinned by science, which can be applied by farmers, landowners and stakeholders to facilitate rehabilitation and improve agricultural waterway health.This handout provides examples of the steps taken and tools used to restore two agricultural waterways in lowland Canterbury as part of the CAREX project.

This poster was presented at the 2016 NZFSS conference held in Invercargill.Poster abstract:Stress-tolerant species that reside in extreme conditions outside the niche of competitors and predators are likely to be particularly vulnerable to global environmental change. The nationally critical kōwaro (Canterbury mudfish, Neochanna burrowsius) is such a species that persist only in isolated waterbodies on the Canterbury Plains which allow them to avoid predators. However, these habitats are often subject to harsh environmental conditions, such as extreme habitat drying. We investigated, by revisiting sites sampled in 2007 and 2010, how recent consecutive drought years have affected Canterbury mudfish in a ‘stronghold’ metapopulation in the Waianiwaniwa Valley. Consecutive years of drought conditions have triggered a change from adult-dominated populations to ones consisting predominantly of juveniles. This change potentially heralds a shift towards greater population variability due to the lower abundance of highly fecund adults, potentially making these populations less resilient to extreme droughts. We plan to investigate the mechanisms underlying this change, and potential remedies to increase Canterbury mudfish resilience. The dynamics of N. burrowsius populations across a range of drying intensities will be compared using a mark-recapture programme, which will be accompanied by a comparison of food webs to assess how food sources, competitors and predators change with drying intensity. Finally, we will utilise the acquired knowledge to further refine translocation and habitat protection criteria that facilitate mudfish population persistence in the face of global change.

Through the CAREX project, we have tested a series of practical tools, and developed solutions and approaches to address aquatic weed, sediment, and nutrient management issues in agricultural waterways in lowland Canterbury. We have developed a set of steps and toolboxes, underpinned by science, which can be applied by farmers, landowners and stakeholders to facilitate rehabilitation and improve agricultural waterway health.This handout is the third in a series, which focuses on tools to manage sediment in waterways.Suggested citation: Harding, J.S., Hogsden, K.L., Febria, C.M., Devlin, H.S., Collins, K.E., Goeller, B.C, and A.M.
