The contemporary morphofunctional state, distribution and biomass of phytobenthic communities of the Large Phyllophora Field (LPF) or Zernov`s Phyllophora Field and the Small Phyllophora Field (SPF) have been clarified on the basis of material received in international cruises on the research vessels Akademik (2004, 2006), and Poseidon (2008) in the central part of the north-western Black Sea shelf and on Sprut in Karkinitsky Bay (2008). The state of the Phyllophora communities has been used as the most sensitive indicator of the ecological state and trophic level of ecosystem. Of all of the Black Sea macrophytes Phyllophora shows minimum specific surface coefficients. It has been shown that during the existing fluctuations and prevalence of small filamentous algae on the shelf, a positive tendency has been noted for the LPF in restoring phytobenthic communities which is curbed in the process of secondary eutrophication as a result of leaching of nutrients from the bottom sediments. Due to improvement of the nutrient runoff the restoration process of coastal Phyllophora communities in the SPF occurs at a higher stage in contrast to the shelf communities of the LPF. At present the biomass of Phyllophora phytocoenoses of the SPF has been restored to the level of the 1970s. The ecological activity of the morphofunctional pattern of phyllophora communities in the LPF are 5 fold greater than in the SPF which illustrates the more active production processes causing the secondary eutrophication of the shelf. The restoration stage of Phyllophora communities of the SPF is 20-25 years ahead of that in the LPF.
