Comment:

Crome's Broad has had a decrease in the abundance of stoneworts over the past three years (since phoslock treatment), over 50% from 2014 to 2015 and then a further decrease in 2016. The increased levels of filamentous algae found in 2015 and 2016 appear to have been at the expense of the vascular plants and stoneworts. Due to this increase in filamentous algae and decrease in the rarer plants, nutrient enrichment may be one possible cause, alongside natural variability in plant species abundances. An

investigation into the water quality data (under the auspices of the Ant DWP plan) is suggested to help determine the significance of external nutrient sources on water plant growth.

Number of adverse condition reasons: 5
