Lately, the Pro Climb team has been collaborating with Auckland Council, SPS Biota, and DutchTrig to combat a formidable adversary threatening the green canopy of Auckland’s landscapes, namely Dutch Elm Tree Disease (DED).
In this blog, we delve into the proactive measures we’re taking to safeguard the majestic elms from the destructive impact of DED. Learn the latest innovative approach to inoculating these trees with beneficial fungi, an eco-friendly strategy that not only addresses the current threat but also establishes a resilient defence against the march of Dutch Elm Tree Disease.
Join us on this journey as we explore the intricacies of our collaboration and the vital role each partner plays in ensuring the longevity and health of Auckland’s iconic elm trees.
Understanding the Threat of Dutch Elm Disease (DED)
Dutch Elm Disease (DED) is a formidable threat to Elm populations in both North America and Europe, and now New Zealand, casting a shadow over the once-thriving communities of these majestic trees. Somewhat similar to the Kauri dieback disease, DED originates from a fungus that targets Elm species. DED has proven to be a relentless adversary, causing widespread devastation in its wake.
The disease manifests through a series of symptoms, including wilting leaves, discolouration, and, ultimately, the death of the tree. As we delve into the intricacies of this silent menace, it becomes imperative to grasp the urgency of addressing DED and implementing effective measures to safeguard our cherished Elm trees.
Dutch Elm Disease Mitigation Strategies
Dutch Elm Disease poses a significant threat to elm trees, necessitating comprehensive mitigation strategies. Traditional methods, including tree pruning, sanitation practices, and the application of fungicides or planting-resistant tree varieties, have long been employed to curb the spread of the disease.
However, a promising and innovative approach involves introducing beneficial fungi to enhance the trees’ natural defence mechanisms. By harnessing the power of symbiotic relationships between trees and beneficial fungi, there is potential to bolster the resilience of elms against Dutch Elm Disease in a more sustainable and environmentally friendly manner.
This forward-thinking strategy reflects a commitment to exploring novel solutions for the conservation of our valuable tree species.
The Role of Beneficial Fungi
Beneficial fungi play a crucial role in safeguarding Elm trees against Dutch Elm Disease (DED) by acting as a natural shield and supporting the trees in their inherent defence mechanisms. These fungi contribute to the intricate nutrient cycle by breaking down materials within stressed and diseased trees.
This process not only aids in recycling essential nutrients but also assists in preventing the spread of DED. By participating in the decay of affected tree matter, beneficial fungi actively mitigate the impact of the disease, fostering a healthier and more resilient forest ecosystem. Their symbiotic relationship with Elm trees showcases the intricate balance of nature, emphasising the significance of fungi in maintaining the vitality and regeneration of forested landscapes.
Preserving Natural Landscapes
It is important to understand the importance of collective efforts to preserve our natural landscapes and safeguard our trees, whether native like the Kauri or not.
Through our shared commitment to supporting our environment, we can ensure the longevity and splendour of these natural wonders for generations to come.

What are the symptoms of Dutch Elm Tree Disease?
Symptoms of Dutch Elm Tree Disease include wilting, yellowing, and curling of leaves, as well as brown streaks in the wood, ultimately leading to tree death.
What is the role of beneficial fungi in preventing Dutch Elm Disease?
Beneficial fungi can help prevent Dutch Elm Disease by colonising the tree’s vascular system, creating a barrier that inhibits the pathogen responsible for the disease from spreading, thereby protecting the elm tree.
