Land Use

The land around the Menai Strait is used for catlle and sheep farming. In the post-Brexit era, farmers are required to expand their operations, which has led to the government's approval of previously banned chemicals. While these chemicals may assist farmers in their efforts to expand, they pose a significant threat to the wildlife in the Strait and its rivers as they leach into the watercourse.

Agricultural practices have a significant impact on water quality, primarily through the release of nutrients and chemicals such as pesticides into the water environment. The presence of microbiological organisms in manure can also lead to biological contamination. Furthermore, soil erosion and runoff exacerbate the problem by carrying sediment and other pollutants into the watercourse

Climate change has also contributed to the degradation of water quality in the region. Intense rainfall events result in higher sediment loss from fields, which can lead to habitat loss and a process known as Eutrophication Eutrophication can result in the proliferation of invasive blooms, even in areas with significant tidal range like the Strait.

It is essential to take action to prevent further degradation of the water quality in the Strait and its surrounding rivers. This may include working to support farmers with more sustainable agricultural practices, reducing the use of harmful chemicals, and mitigating the impact of climate change By doing so, we can protect the region's rich biodiversity and ensure its continued viability for future generations

How does this impact the Menai Strait?

These chemicals and nutrients leach into the watercourse, leading to increased pollution and a reduction in water quality The presence of microbiological organisms in manure can also lead to biological contamination, further exacerbating the problem.

The degraded water quality has a significant impact on the wildlife in the area The increased pollution can lead to reduced oxygen levels, making it difficult for fish and other aquatic species to survive. Furthermore, the presence of harmful chemicals can be toxic to many different types of wildlife, from fish to birds and mammals that rely on the water for food or shelter
