Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Limit, cease or prohibit the dumping of untreated sewage We found no studies that evaluated the effects of limiting, ceasing or prohibiting the dumping of untreated sewage on subtidal benthic invertebrate populations. ‘We found no studies’ means that we have not yet found any studies that have directly evaluated this intervention during our systematic journal and report searches. Therefore, we have no evidence to indicate whether or not the intervention has any desirable or harmful effects.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2178https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2178Tue, 22 Oct 2019 12:29:28 +0100Collected Evidence: Collected Evidence: Limit, cease or prohibit the dumping of sewage sludge Two studies examined the effects of ceasing or prohibiting the dumping of sewage sludge on subtidal benthic invertebrate populations. One study was in the New York Bight (USA), one in the North Sea (UK). COMMUNITY RESPONSE (2 STUDIES) Overall community composition (2 studies): One before-and-after, site comparison study in the New York Bight found that after ceasing sewage sludge dumping, overall invertebrate community composition became more similar to less disturbed sites. One replicated, site comparison study in the North Sea found that overall invertebrate community composition changed but remained different to that of natural sites. POPULATION RESPONSE (2 STUDIES) Overall abundance (1 study): One replicated, site comparison study in the North Sea found that after ceasing sewage sludge dumping, overall invertebrate abundance became similar to that of natural sites. Worm abundance (1 study): One before-and-after, site comparison study in the New York Bight found that after ceasing sewage sludge dumping, abundance of pollution-indicator polychaete worms decreased and became similar to that of natural sites.

The study was in the Bay of Biscay (Spain). COMMUNITY RESPONSE (1 STUDY) Overall community composition (1 study): One before-and-after, site comparison study in the Bay of Biscay found that after introducing a secondary treatment of sewage wastewaters, invertebrate community composition at an impacted site did not significantly change compared to unimpacted sites. Overall richness/diversity (1 study): One before-and-after, site comparison study in the Bay of Biscay found that after introducing a secondary treatment of sewage wastewaters, invertebrate richness and diversity at an impacted site did not significantly change compared to unimpacted sites. POPULATION RESPONSE (1 STUDY) Overall abundance (1 study): One before-and-after, site comparison study in the Bay of Biscay found that after introducing a secondary treatment of sewage wastewaters, total cover of invertebrates significantly increased at an impacted site at 8 m but not 3 m depth, compared to unimpacted sites.
