Which of the following actions can reduce invasive species in wetland areas?

Implementing controlled grazing management is effective in reducing invasive species in wetland areas because it allows for the careful regulation of animal grazing to maintain the health of native plant species. Controlled grazing can help suppress invasive plants that may not be as resilient to grazing pressure while promoting the growth of native species by allowing them the space and resources needed to thrive.

This method can improve the overall biodiversity of the wetland ecosystem by ensuring that native species are not outcompeted by invasive species. Moreover, with proper management, controlled grazing can also enhance soil health and water quality, which are essential for the vitality of wetland environments.

In contrast, increasing grazing pressure may lead to overgrazing, which can further stress native plants and promote the spread of invasive species. Similarly, while promoting regular burning can sometimes be used in ecosystem management, it must be applied cautiously, as inappropriate timing or frequency can harm native species. Lastly, introducing more non-native species typically exacerbates the problem of invasiveness, rather than resolving it.
