Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Pay monetary compensation for habitat damage remediation We found no studies that evaluated the effects of paying monetary compensation for habitat damage remediation 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%2F2263https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2263Wed, 23 Oct 2019 10:58:53 +0100Collected Evidence: Collected Evidence: Remove and relocate habitat-forming (biogenic) species before onset of impactful activities One study examined the effects of removing and relocating habitat-forming species before onset of impactful activities on subtidal benthic invertebrates. The study was in the Fal Estuary (UK). COMMUNITY RESPONSE (1 STUDY) Overall community composition (1 study): One replicated, paired, controlled study in the Fal Estuary found that invertebrate community composition was different in plots where maërl bed habitat had been removed and relayed compared to undisturbed maërl after five weeks, but similar after 44 weeks. Overall species richness/diversity (1 study): One replicated, paired, controlled study in the Fal Estuary found that invertebrate species richness was lower in plots where maërl bed habitat had been removed and relayed compared to undisturbed maërl after five weeks, but similar after 44 weeks. POPULATION RESPONSE (1 STUDY) Overall abundance (1 study): One replicated, paired, controlled study in the Fal Estuary found that invertebrate abundance was different in plots where maërl bed habitat had been removed and relayed compared to undisturbed maërl after five weeks, but similar after 44 weeks.

One study was in the Delaware Bay (USA), the other in the Persian Gulf (Kuwait). COMMUNITY RESPONSE (1 STUDY) Overall richness/diversity (1 study): One study in the Persian Gulf found that an area of low ecological value restored to offset habitat lost to land reclamation was colonized by over 198 invertebrate species. POPULATION RESPONSE (0 STUDIES) OTHER (1 STUDY) Biological production (1 study): One study in Delaware Bay found that an artificial reef built to offset lost soft-sediment habitat had higher annual secondary production/unit area from sessile invertebrates, but lower total annual secondary production, compared to habitat similar to that lost.
