Wetlands accounts for one of the world’s most productive ecosystems and plenty of organisms depends on these environments. Wetlands supports not only biological diversity, but also indirectly us humans by its ecosystem services like recreation, mitigate flooding, water purification and as a carbon sink. Together with Hushållningssällskapet in Halland and their project Life-Goodstream we investigated whether there is a connection between the amount of underwater vegetation and the abundance of aquatic invertebrates in constructed wetlands and what impact this might had on biodiversity. Our results showed no significant correlations between underwater vegetation and number of aquatic invertebrates and variation of taxa. However, floating vegetation and the variation of plant species had a greater impact on the invertebrate community. Based on our results we found support that a heterogeneous habitat positively affected the biodiversity of invertebrate communities since we found significant relationships between the number of plant species, number of individuals (without the extreme groups) and number of groups, similar results have shown in other studies which further supports our results. We also investigated whether the invasive plant species. We also investigated whether the presence of the invasive plant species Elodea nuttallii (water plague) significantly affected the invertebrate community but found that the results didn’t differ from the other premises, without E. nuttallii.
