Our freshwater habitats and estuaries are complex ecosystems that support a broad variety of animal and plant life. These waterways form sites of outstanding natural beauty whilst providing an essential space for wildlife to flourish. Aquatic ecosystems are also very sensitive, where a correct balance of nutrients in the water is essential for the health of plant and animal life to be maintained.
As such, nutrient pollution can have a big impact on our waterways and on the wildlife that lives in these spaces. Increased levels of nitrogen and phosphorus can be incredibly harmful, where this can be caused by runoff from sewage treatment works, agricultural sites or industrial projects. Read on to find out more about how unfavourable nitrate levels can harm our waterways.
Plant Growth
The major issue that is caused by unfavourable nitrate conditions is the process of eutrophication, where an increase in certain nutrients can dramatically disrupt the natural ecosystem. High nitrate levels can stimulate algae growth and the growth of other destructive plants, which can quickly drain an ecosystem of life. Fast growing plants such as algae can smother other vegetation whilst destroying animal habitats, creating so called ‘dead zones’ in our waterways.
Wildlife
Wildlife in our waterways will suffer from a change in plant growth, where this can destroy their habitats, disrupt mating cycles and reduce water quality. More directly, aquatic animals can also suffer from nitrate poisoning, which impacts the ability of cells to utilise oxygen. Eventually this can lead to high stress levels, a compromised immune system or even suffocation in fish and other wildlife.
Human Health
Recent scientific investigations have suggested that it may be harmful for human health to consume water with abnormally high nitrate levels. Potential health concerns could include nausea, digestive issues and headaches, where this could impact which rivers are safe for wild swimming.
Lizard Landscape Design & Ecology: Nitrate Neutrality Guidance For Your Project
At Lizard Landscape Design, we can provide your new build or project with accurate Nitrate Budget Calculations in accordance with guidelines offered by Natural England. In vulnerable or protected areas, new developments must demonstrate nitrate neutrality to secure approval, where we can advise you on this process whilst talking you through various mitigation requirements.
In addition to this, we also offer landscape planning services, environmental impact surveys and ecological assessments to help you to get your project started. Get in touch with us today to find out more.
