Rare white rātā in Lower Hutt, rarer than the kākāpō — STUFF ARTICLE Nov '19
It is rarer than the kākāpō and most people have never heard of it but a population of Bartlett's white rātā is thriving in Lower Hutt. Hutt City Council staff recently used a drone to survey trees in Percy Scenic Reserve and made an unexpected discovery. One of the seven Bartlett's rātā was flowering, which means it has the potential to be used in a project that is trying to save the critically endangered tree.
Fossil Atmospheres — CITIZEN SCIENCE PROJECT, SLH SUMMARY and LINKS
By comparing some features of fossilised plants with the same features of plants living today, scientists hope to be able to learn more about the effect of changing carbon dioxide (CO2) levels in our atmosphere and to understand what effect climate change might have on life on Earth in the long term. This project involves citizens categorising two types of cell on images taken by electron microscopes of the underside of gingko tree leaves.
Phytophthora agathidicida: research progress, cultural perspectives and knowledge gaps in the control and management of kauri dieback in New Zealand
Kauri (Agathis australis), which is one of the world's largest and longest‐living conifer species, is under threat from a root and collar dieback disease caused by the oomycete pathogen Phytophthora agathidicida. This disease has profound effects on both forest ecosystems and human society, particularly indigenous Māori, for whom kauri is a taonga or treasure of immense significance. This review brings together existing scientific knowledge about the pathogen and the devastating disease...
Professor Spends 2 Years Sitting with an Ancient Oak
Like Henry David Thoreau went to the woods, James Canton went to a very old tree. Specifically, the professor spent two years sitting with and studying the 800-year-old Honywood Oak in North Essex, England. Canton originally went there to observe the oak, but came away better understanding not just the tree, but also himself. Canton's new book, "The Oak Papers," reflects on what he learned in his time spent with the ancient oak, listening to the natural world.
Unlocking the benefits of bark
Over 2 million tonnes of bark are produced by NZ’s forestry industry every year. It is an underutilised resource. Pine bark is a rich source of polyphenols, terpenes & resin acids that have unique functional & structural properties including antioxidant, antibacterial & waterproofing. New technologies & integrated processing are needed to recover all the potential value from bark. Scion is setting out to create new processes and products through our collaborative Bark Biorefinery programme
