Nature - Based Solutions for Environmental Management

Non - Active area at Wazo Hill quarry is large compared to rehabilitated area, and contain a variety of local pollinator species that are not present to rehabilitated area such as Catopsilia florella and Anax imperator, hence i come up with an idea to attract those local pollinator species by using native tree. Also in my research study the stressors such as dusts are highly experienced in rehabilitated area since they are at lower elevation compared to the non - active area, hence the use of specific native tree to suppress dust level in these area was critical

Strategic Tree Selection and Planting Zones for Dust suppression

To combat dust generated near roads, I have established and plant a buffer zone using tree species known for their excellent dust-trapping capabilities.

Zone 1: The outer perimeter of this zone is planted with Croton megalocarpus. This species was chosen for its broad, textured leaves that effectively capture and hold dust particles, creating a natural filter.

Zone 2: Following the Croton megalocarpus zone, i have planted Afzelia quanzensis. These trees provide a second layer of defense, further reducing the dust that passes through the first zone.

Strategic Tree selection for attraction of pollinator

Beyond the dust suppression zones, we have created a dedicated area to attract and support local invertebrate pollinators. This is a critical step in restoring the ecosystem's health and functionality.

Native trees species selected are Trichilia emetica and Acacia pycnantha were selected for this zone due to their native status and proven ability to produce flowers rich in nectar and pollen, which are highly attractive to a wide range of local pollinator
