[ENGLISH]
North of
Primorsko, in the zone between the
Stamopolu lagoon and the beach, is
situated one of the best preserved sand dunes regions along the
Black sea coast. The highest dune ridges reach 19m and are
exclusively fascinating view for all visitors of
Primorsko.
Climate:
Summers are usually dry and warm. Temperatures in June vary
(22-23°C) due to the cooling influence of the sea. The closeness of
the relatively warm waters makes the winters the mildest in the
whole country.
The living world of the dunes:
There
is a large number of specific sand
(psammophite) kinds of plants. Eighty
plant kinds have been found among the dunes. Fourteen of them are
included in the Red Book of Bulgaria, which concerns endangered
animal and vegetation species.
Big is the
diversity of invertebrates, rare and endangered amphibian species,
reptiles and mammals.
Geomorphological
background:
The sand beach
strip built of close fine sand is formed to the East of
Stamopolu lagoon. The fraction
0,5-0,25 mm takes 74%. Towards the South
direction, the sand became in component predominates (carbonate
content reaches 60%). The contents of heavy minerals is too limited
- 0,8-1,0%. The coefficient of
sedimentation for the bay and the beach are correspondingly
1,30 and 1,12. The strong North-East
wind has moved the sand towards the inside of the dry land more
than 600 m. The zone between the lagoon and beach strip is
characteristic dune landscape. In some places the dunes are lie on
calciferous sandstones.
The crests of the
highest dunes are 19 m in height above sea-level and in 35° C
directed. They are formed by South- East wind which velocity
sometimes is over 15 m/s in December. The dunes in the region of
Stamopolu
lagoon obviously are not connected
with the Ropotamo river.

teplych vod naopak zpusobuje, ze zimy jsou zde nejmirnejsi v cele
zemi.
Flora v okoli:
V oblasti se nachazi velke mnozstvi piscitych druhu rostlin
(psammophite). Mezi dunami bylo nalezeno na 80 druhu. 14 z nich je
uvedeno v Cervene knize Bulharska na seznamu ohrozenych
druhu.
Velka je tez rozmanitost bezobratlych, vzacnych a ohrozenych druhu
obojzivelniku, plazu a savcu.
