Invasive Species Control

What is it? This entails the strategic identification and removal of aggressive, non-native plants that disrupt the local ecosystem. Rather than letting these weeds proliferate, the goal is to replace them with robust, high-value trees that support local wildlife and provide sustainable, long-term greenery.

Why it matters for Yerevan. Ailanthus was planted as a street tree decades ago before its invasive nature was understood. Today, it aggressively colonizes neglected wastelands and sprouts in asphalt cracks, displacing climate-adapted vegetation. Addressing this spread now is critical to prevent these weeds from becoming an irreversible environmental burden and to ensure space is used for trees that provide effective cooling.

The Standard. A centralized management plan is essential. This includes a strict ban on planting known invasives and using scientifically proven removal techniques to prevent regrowth. Replacement plans must be immediate, ensuring weeds are swapped for climate-resilient species without losing canopy cover.

Current Status. Although new plantings have stopped, mature Ailanthus trees still can be found on some streets and in parks, while neglected land is actively being overrun by these self-seeding weeds. We advocate for a centralized program to systematically remove these threats and reclaim green spaces.
