Ban on Topping

What is it? Topping is the indiscriminate cutting of tree branches to stubs or lateral branches that are too small to sustain the tree. Unlike professional pruning, which selectively removes branches to support health and structure, topping is a damaging practice that starves the tree, destroys its natural architecture, and inevitably initiates internal decay.

Why it matters for Yerevan. In Yerevan’s semi-arid climate, preserving every square meter of shade is critical. Topping removes the leafy canopy that cools our asphalt and filters our dusty air. Without leaves, the tree's bark is exposed to scorching summer sun, leading to sunscald and severe stress. These weakened trees become easy targets for pests and struggle to survive in our dry, alkaline soil. Furthermore, the rapid regrowth—or "water sprouts"—from topped trees is weakly attached, creating dangerous hazards during high winds.

The Standard. Kanach Yerevan advocates for a strict prohibition on topping for public trees. Instead, we must adopt international best practices that focus on structural pruning and canopy preservation. Maintenance should be performed by trained specialists using certified arboriculture techniques to maintain the tree's natural form. This shift will ensure a safer, cooler, and more sustainable green canopy for our city.

Current status. Topping is the main method of cutting trees currently in use by the city in public areas, with proper cutting practices only observable on private property.
