Hollow Bearing Trees

This tree contains a small hollow. Hollow-bearing trees play a vital role in healthy ecosystems, providing essential shelter and nesting sites for a wide variety of wildlife. Many birds, mammals, reptiles, and insects rely on the natural hollows that form in older trees, some species depending on them entirely for survival. These trees support biodiversity by offering safe spaces for breeding, resting, and protection from predators and harsh weather. Since hollows can take over a century to develop, old trees are irreplaceable in the short term, making their conservation especially important. By protecting hollow-bearing trees, we help maintain the delicate balance of ecosystems and ensure that future generations of wildlife have the habitats they need to thrive.

Estimation of Tree Age (DBM Analysis)

This tree is categorised as an “old tree” based on the following diameter at breast height (DBM) categories -

• 150-400 mm (juvenile and adolescent trees)
• 401-600 mm (young mature trees)
• 601-800 mm (mature trees)
• 801-1200mm (old trees)
• 1201-1600 mm (very old trees)
• >1601 (veteran trees)
