When It Hits the Fan?

Most terrestrial ecosystems are low nutrient environments. In Europe, excessive nutrients in such locations, reduce biodiversity, by favouring a few plants like stinging nettles and toxic hogweed. An 18 month study, carried out in Ghent (Belgium) showed that dog urine and faeces over-fertilise pathways in nature reserves (https://www.theguardian.com/environment/2022/feb/07/dog-pee-and-poo-harming-nature-reserves-study). The study looked at four nature reserves just outside Ghent, where people took their dogs for walks. It found that dog urine and faeces added circa 11kg of nitrates and 5kg of phosphates per hectare. These values, would be likely to damage wildlife, and would be illegal on agricultural land. The dog walkers seemed to have no idea that their pets were causing a pollution problem. Perhaps they can be persuaded to clean up the faeces in nature reserves as well as on city streets? Provision could be made for this. It's worth adding, that walking dogs in nature reserves can be a cause of powerful disturbance to wild mammals and birds. This is also damaging to nature.
