This educational wall chart explains alien invasive plants and the serious environmental problems they cause when introduced into natural ecosystems. It begins by defining alien invasive plants as species that have been deliberately or accidentally introduced into a country and have spread aggressively, often outcompeting indigenous vegetation. The chart highlights how these plants thrive without human care, multiply rapidly, and spread through disturbed areas such as roadsides, rivers, abandoned land, and human settlements.

A key section titled why invaders must be controlled shows the environmental impact of invasive plants. Illustrated examples explain how invasive trees replace natural forests, consume excessive water, reduce river flow, dry up wetlands, and increase flooding risks. Aquatic invaders such as water hyacinth are shown blocking waterways, affecting irrigation systems, hydroelectric turbines, and aquatic life.

The wall chart also presents practical methods for controlling invasive alien plants. These include manual or mechanical control, chemical control using herbicides, and biological control using natural enemies such as insects and fungi. Each method is visually supported to aid understanding.

A South Africa specific section categorises alien invasive plants into three legal categories, with examples such as lantana, bugweed, wattle trees, gum trees, syringa, and privet. This wall chart doubles effectively as a poster for classrooms, environmental studies, geography lessons, and conservation awareness spaces.

Our wallcharts are engineered for durability and educational impact, designed to withstand the rigors of both classroom and home environments.
