Published as: Early successional patterns of invertebrates in artificial reefs established at clear and silty areas in Bolinao, Pangasinan, Northern Philippines | Technique: Substrate Addition - Artificial reef | Disturbance addressed: General degradation | Genera: n/a | Method: Colonization and recruitment of invertebrates were studied in 32 tent-like concrete blocks used as artificial reefs in silty and in clear reef areas in Pangasinan, northern Philippines. Abundance, species richness and composition were compared between differently oriented surfaces on the blocks. | Post-restoration monitoring: 7 months | Authors' conclusion: Around 13 taxa of invertebrates were observed as early recruits on the patch reefs in the Clear site, and 11 taxa for the Silty site. In the Clear site, the total number of taxa of sessile and mobile organisms present on the AR blocks exhibited a generally increasing trend 4 months after deployment. Colonial ascidians were particularly dominant during the first 4 months. Cirripeds and anthozoans were observed only after 7 months. Benthic communities showed a distinct pattern with regards to their position within the blocks (whether inside, outside and/or sides). | Lessons reported: Block orientation and water clarity influence the development of benthic communities on artificial reefs | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work. No contribution to the condition index is recorded: the source reports survival of transplanted material, which is not a measure of ecosystem condition.

Recorded result

No result recorded yet. A result is recorded when the project moves to Paused, Completed or Discontinued.

A variable shows "pending" instead of a contribution when no domain area has been set for it yet — the share of the world a project touched cannot be computed without one. The health percentages are accurate regardless.
