Progressive methodological approach of forming of protected areas was
realized in practical nature protection conception: Pan European
Ecological Network with special task on forming of marine ecological
network of Europe (European Coastal Marina Ecological Network) in
1999.
 There are 142 terrestrial, 53 freshwater, and 43 marine
ecoregions in the World. The Black Sea is part of the
Mediterranean ecoregion.
Example of marine corridor of the Pan European ecological network in south-east Europe
The total protected area of the Black Sea amounts to 68 263 км2, but it differs
in area in each country. The largest number of MPAs of different status is
concentrated in Ukraine which has a maximum length of coastline – 1 628 km
or 37% and 55 750 km2 or 57% of the total Black Sea shelf area.
Review of ecological networks and corridors is one of the technical
guidance manual for protected area systems
Bennett G. & Mulongoy K.J. Review of experience
with ecological networks, corridors and buffer zones.Secretariat of the Convention on Biological Diversity.Montreal, 2006.- Technical Series No. 23.- 100pp.
Guiding principles for the Establishment
of Marine Protected Areas in the Black
Sea (approve CBD AG in 2008)
The aim of this study is to work out the methodology of
a quantitative approach determining the biological
value of marine aquatic areas (lagoons, bays etc.) for
forming ecological corridors and determination of order of
creation of new or expansions of existent МPАs (on
example of marine waterbodies of Ukraine).
Peculiarities of aquatic ecosystems:
1. Concentration of life in coastal and shelf area to the depth of solar
penetration.
2.
Definite advantage in selection of the protected areas according to
benthic biocenoses, as those bound with the landscape (in contrast to
pelagic one).
There were singled out 34 different aquatic objects in
Ukrainian part of the Black Sea coast:
Title
13 – Bays,
13 – limans (estuaries),
2 – lagoons,
2 – lakes,
1 – Delta (Danube),
1 – Island (Zmeiny),
1 – open shelf area,
1 – strait (Kerch).
Key characteristics of aquatic objects:
KRDB – total number of Red Data Book species,
KEAM – ecological activity of macrophytes,
KBB – total number of benthic biocoenoses,
KMZB – total number of macrozoobentic species,
KP/B – ratio between plankton and benthos biomass,
KPP – primary production of phytoplankton,
KAI – integrated estimation of anthropogenic impact.
Кƒ = (Ki min a)0,5 · ( K1a1 · K2a2 · … · Knan)1/2n
Кƒ - integrated index of biological significance of aquatic object;
К1, К2, Кn – measure of key characteristics in each aquatic object;
а1, а2, аn – weight coefficient of each key characteristics;
n – number of key characteristics.

Strategy
Framework
Directive
(Annex III,
Table 1)
•Physical and chemical features (distribution of nutrient):
•Biological features (phytoplankton and zooplankton
communities; macro-algae and invertebrate bottom
fauna; status of species).
•Other features (chemicals, sediments contamination,
hotspots, health issues etc.).
•Habitat types (structure and substrata composition of the
seabed): 5 ecotones - separate analyses.
KBB – total number of benthic biocoenoses,
KAI – integrated estimation of anthropogenic
impact
KRDB – total number of Red Data Book species,
KMZB – total number of macrozoobentic species,
KP/B – ratio between plankton and benthos biomass,
KPP – primary production of phytoplankton,
KEAM – ecological activity of macrophytes.
KAI – integrated estimation of anthropogenic impact

Identification of quantities characteristics of aquatic water bodies
Values of КРР (primary productions) was determined by oxygen and radiocarbon methods, or
chlorophyll «а» content were estimated in the same units (mg О2·l-1·d-1) according to the formula:
КРР= 1 - lg[8,5 / (8,5 - Kaverage)]
where Kaverage - the value of the characteristic of a given water body.
Index of ecological activity of macrophytes (КEAМ) was determining as average of specific
surface of the first three dominant species (Minicheva, 1998, Minicheva et al., 2003) on a formula:
КEAМ= 10 · S/Waverage
where - S/Waverage - arithmetical mean to the specific surface (S is area of surface and W is
biomass of aquatic plants) of three dominant species of macrophytobenthos in each water body.
Numeral value КP/B was determined for water column by above square meter of bottom surface,
taking into account the middle depth of water body on a formula: КP/B = 1 - lg (1000 · Kaverage) / 5
where Kaverage - the value of the characteristic of a given water body.
All characteristics of biological diversity of the investigated water bodies (KMZB, KBB and KRDB
were determined on formula: Кi = Kaverage / Kmax
where Kaverage - the value of the characteristic of a given water body, Kmax - the maximum possible
value in a given ecotone.
