A tree in good health radiates a vibrant sound
In the heart of Schneverdingen, a city famed for its verdant greenery, a worrying issue has surfaced. Matthias Reimers, the city's head gardener, has received numerous calls from concerned citizens over the past two weeks.
The cause of the alarm is the giant polypore fungus, a notorious foe of oak trees. This fungus, known for causing white rot, weakens the stability and strength of the wood, making the trees vulnerable to falling.
Recently, on German Unity Day, a gust of wind toppled an oak tree in Walter-Peters Park, dedicated to the state of Bavaria, trapping two people. Upon inspection, it was discovered that the fallen tree was infested with the giant polypore fungus.
Reimers and his team of seven gardeners from the municipal works department are keeping a close watch on the city's tree population, which numbers approximately 20,000. The red oak in Walter-Peters Park, with some bare branches, has been rated as having low vitality by Reimers, who uses an extendable iron rod, a rubber mallet, and a resistance drill meter to assess the health of trees.
The giant polypore fungus is notoriously difficult to detect in its early stages, as it penetrates the trunk through dead roots and damages healthy ones. This makes it a silent but potentially dangerous threat to Schneverdingen's trees.
Professor Dr. Vera Göhre, a specialist in the field of diseases and management of fungal species in trees, leads a molecular biology team investigating how pathogenic fungi communicate with and affect their host plants, including trees. Her research could provide valuable insights into the behavior of the giant polypore fungus and potential strategies for its control.
Reimers also notes that this year is a 'fungi year,' due to the damp and warm weather that has accelerated the growth and spread of fungi. The Tree Portal, a resource for information about tree health and diseases, advises regular inspections and careful monitoring of trees for signs of the giant polypore fungus.
As the city of Schneverdingen continues to grapple with this threat, the importance of regular tree inspections, twice a year, cannot be overstated. The health of the city's tree population is at stake, and with it, the beauty and vibrancy that trees bring to the city.
