New Paper on Predicting Soil Water Movement and Storage in Forested Catchments in the Journal of Hydrology

Latest Scientific Paper! Soils are a crucial component of forest hydrology - for water storage and release. This Forest Flows research, led by Shanxi Agricultural University's Dr Hongfen Zhu, developed a novel way to optimise where to place sensors within a forested catchment to capture soil water movement and storage at different depths. These are called time stable locations. Thus, we need a lot less sensors to monitor soil water throughout a forest catchment. Unlike previous studies, we demon...

Forest Hydrology going to the stars

Scion was successful with two projects being funded Ministry of Business, Innovation and Employment NZ-NASA Research Partnership. Dean Meason is leading one on the tree-water (hydrological) cycle from space! Building on the success of the Forest Flows Endeavour Programme, Scion has partnered with NASA Jet Propulsion Laboratory, University of Massachusetts Amherst and NIWAto develop a proof-of-concept framework at different scales in the Far North/Te Hiku ō Te Ika of New Zealand. This will provi...

New Paper on Remote Sensing Dry Periods in Forests in Remote Sensing Journal

New published paper! This Forest Flows research led by University of Massachusetts Amherst Kostas Andreadis compared NASA - National Aeronautics and Space Administration and European Space Agency - ESA satellite data with ground sensor networks demonstrated the ability of satellite-based remote sensing to detect and quantify dry periods in planted forests in new Zealand. See link below.Previous studies had difficulties in characterizing meteorological drought f...

Sharing and learning knowledge at the Ngā Puawai o Te-Oneroa-a-Tōhe

It was an amazing experience to attend the Ngā Puawai o Te-Oneroa-a-Tōhe in Kaitāia on September 28th-30th. As one of the over 80 invited stakeholders, the remarkable wānanga brought together diverse backgrounds to deliberate the future of Te Oneroa-a-Tōhe (90 Mile Beach). It was convened under the guidance of Te Oneroa a Tōhe Beach Management Board and supported by Te Rūnanga o Te Rarawa. It was a humbling experience in learning how to share the nearby site's first results from the&...

New Forest Flows Paper in CATENA!

New paper! This research, in the high impact CATENA journal, looks at the spatial resolution of digital elevation maps (DEM) and interpolation of topography and soil properties. This interpolation commonly used for all sort of analyses, like forestry, agriculture, geology, remote sensing and hydrology. However, they could be fundamentally flawed if the spatial pattern is distorted. Doctor Serajis Salekin led the team and found:* Mean absolute errors for primary and secondary topographi...

NZ’s forests soak up far more extreme rainfall than we realise

The largest study of its kind in the world has revealed how our forests may soak up much more water in extreme rain than scientists first thought.The new findings – showing how one forest north of Auckland responded to two of the year’s biggest deluges – come from a five-year, $13m project led by Scion.The new data showed that, during the destructive Auckland Anniversary floods and ex-tropical Cyclone Gabrielle weeks later, Mahurangi Forest retained nearly 60 per cent of the 229mm of rain ...

Forest sponges: New research reveals how forests absorb water in extreme weather events

New research is showing how effective forests are at mitigating the effects of extreme rainfall during severe weather events.High resolution data collected from Mahurangi Forest near Auckland during the Auckland Anniversary weekend floods and Cyclone Gabrielle shows that nearly 60% of the rain that fell during those events was stored within the forest rather than flowing immediately across the ground and into waterways. The forest catchment was in effect acting as a sponge, holding on to water t...

Third airborne campaign is complete!

The third airborne campaign for the MBIE Endeavour Forest Flows programme is complete! Dr Delwyn Moller and team flew across 6 sites across Aotearoa New Zealand with SlimSAR to measure and map soil moisture at a fine resolution to a depth of 1m. This cutting edge technology provides for the first time direct measurements of soil properties in remote & difficult to reach areas. Two of the sites were directly in the path of the January 27th and Cyclone Gabrielle extreme weather events. Once pr...

BBC: Planting trees improves soil quality and water storage

Happy New Year!! The January 2nd BBC news article (click on link below) is about a surfer who worked the last 20 years restoring degraded pastural land in Panama into a productive agroforest system with crops and trees. Thanks to the advice from the local Ngäbe-Buglé indigenous community, it is "a thriving, forested eco-haven". It says "... also provides "green infrastructure" that can protect the environment, such as soil in intact forests which can absorb water to prevent flooding and relea...

Forest Flows has started its second aerial campaign collecting remote sensing data!

This spring campaign, led by The University of Auckland's Dr Delwyn Moller, provides key soil moisture and forest canopy data from various sites across NZ. Remote sensing data are collected when the forested catchments are wet (spring) and dry (late summer) to provide an unparalleled insight into the key hydrological processes that control planted forest water use, rainfall storage and release right across the catchment.The leading edge technology SlimSAR, uses L-Band and P-Band radar ...

Is the reputation of Eucalyptus plantations for using more water than Pinus plantations justified?

AbstractThe effect of Eucalyptus plantations on water balance is thought to be more severe than for commercial alternatives such as Pinus species. Although this perception is firmly entrenched, even in the scientific community, only four direct comparisons of the effect on the water balance of a Eucalyptus species and a commercial alternative have been published. One of these, from South Africa, showed that Eucalyptus grandis caused a larger and more rapid...

Developing the novel integrated forest hydrology catchment model bespoke

Scion hosted Dr. Don White, Director and lead researcher of Whitegum Forest and Natural Resource Management for 6 weeks. He worked with inFact Limited and NIWA to develop and improved the novel integrated forest hydrology catchment model bespoke for the Ministry of Business, Innovation and Employment Endeavour Forest Flows programme. Although the model is at an early stage of development, it is already providing very good predictions of tree water use and ...

Successful deployment of the TriOS Optical Sensors NICO nitrate sensor

The Forest Flows Ministry of Business, Innovation and Employment Endeavour programme has successfully deployed TriOS Optical Sensors NICO nitrate sensor to continuously measure stream nitrate in NZ's planted forest catchments. These sensors will give us an unparalleled understanding of daily nitrate fluxes in planted forests throughout the year. This is poorly understood. Measuring the stream continuously avoids the costs and logistics with taking water samples in planted forests once ...
