#Collapse Likelihood: 40% probability of widespread #dieback if warming reaches 2.0^{C}.
Trigger: Combined #deforestation exceeding 22% and regional rainfall reduction of 30%.
Impact Mechanism: Release of up to 90 billion tons of #carbon, potentially adding 0.3^{C} to #global warming.

The #pre-print for the Australian #fieldwork we did last February is now out! We show snow gum #dieback alters #volatile emissions, especially increasing #monoterpene #emissions from damaged trunks. You can read more here: doi.org/10.22541/ess...

The fieldwork sure was one to remember! 🌿🪲☁️🦘

Dieter´s interdisciplinary research into the causes of large-scale #forest #dieback in forests on the islands of #Hawai´i throughout the 1970s and 80s had a global impact and can be seen as exemplary for modern multi-causal forest #decline #research. Context: muse.jhu.edu/pub/5/articl...

March 1972: Hawai´i, Island of Kaua´i, Alaka´i Swamp area. Aerial photograph of forest dieback. Dying and dead Metrosideros trees stand out in grey against the few remaining healthy, green trees. Note on slide: `Terminal dieback, Alaka´i, March 1972`. Photo by Dieter Mueller-Dombois. The Alakaʻi Swamp (Alakaʻi Wilderness Preserve) is a montane rainforest on the island of Kaua´i in Hawai´i, located on a plateau near Mount Waiʻaleʻale, one of the wettest places on Earth. Although it is called a swamp, it is actually a rainforest.

Prof. Mueller-Dombois has been studying #forest #dieback in the Hawaiian #Islands since the late 1960s. This aerial photograph was taken during a reconnaisance flight over the dieback area in #Alaka´i Swamp, Kaua´i, in March 1972. Photo by D. M.-D.. Context: www.google.de/books/editio...

Oak decline: pest outbreak threat or opportunity for saproxylic beetles? A case study from the Czech Republic - Journal of Forestry Research Commercially managed forests are often poor in terms of biodiversity. Saproxylic beetle species could be a useful bioindicating group for the conservation of forest stands. In recent decades, oak stan...

With an excess of #ash to cut in the #woods due to #dieback we have plenty of logs to sell but first they season to meet Govn’t set standards of dryness. With all the cutting, collecting, stacking, chopping and restacking I reckon we handle wood 8-10 times before it’s burnt….saves going to the gym!
