Natural Capital - Headwater Stream Quality (England)

Freshwater invertebrates are good indicators of water quality. Different species vary in their tolerance or sensitivity to nutrient enrichment and other pollutants. Invertebrates are part of complex foodwebs which support fish and plants, as well as breaking down detritus and algae. This map is based on invertebrates in the smallest headwater streams.<div><br /></div><div><div style='font-size: 17px; font-family: &quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif !important;'><div><a href='https://eip.ceh.ac.uk/naturalengland-ncmaps/reports/headwaterQuality_report.pdf' target='_blank'>See the report here &gt;&gt;</a><br /></div><div><a href='https://catalogue.ceh.ac.uk/download?fileIdentifier=d44373e1-23ac-4730-b6db-76c701a9426d_headwaters' target='_blank'>Download the data here &gt;&gt;</a><br /></div></div></div><div><br /></div><div>This suite of ten maps, of different aspects of natural capital, contributes to our understanding of where our natural capital is. The maps have been produced using a range of datasets, including CEH sample data from the Countryside Survey (2007). CEH’s Ecomaps tool has been used to produce maps at an England level through statistical interpretation and extrapolation from the sample data</div>
