Delta has a very rich flora that can be divided in
three major categories:
- plants with floating leaves (white water
lilly, yellow, grass frog, thistles, fennel pondweed),
- riparian plants and plaur (reed, rush, water
fern, sorrel, water mint, water hemlock) and
- Land plants (white willow, poplar, alder, ash,
mixed woods on the banks).
Vegetation is typical for a wetland (reed, bulrush,
sedge, willow blend) and occupies over 70% of the
6% of the area of the a delta is filled with meadows,
which are actually forests of willow, ash, alder,
poplar. These trees grow on fluvial grinds and
they are periodically flooded.
The water ponds are covered by floating and aquatic
avegetation: water lily (Nymphea sp., Nuphar),
thistle (Trapa natans) pond plants (Potamogeton
sp.), Algae (Myriophyllum sp.) Carnivorous plants (Utricularia
sp .) and occupy 2% of the delta area.
Floating islets ( reed
floating layer 1 to 1.6 m thick, composed of intertwining
rhizomes, roots, bound together with humus and
silt brought by the Danube and deposited here)
occupies an area of about 2000 ha. Are often moved
by the wind, plaur can cause difficulties when
crossing or access lakes.i.
There are also forests - Letea (2825
ha) and Caraorman (2250
ha), developed in the lower and more wet areas
between sandbaks know as "hasmace which
made of maple, English oak, ash, aspen, elm, oak,
and so on. The Letea forest is renowned for the
abundance of climbing plants (Periploca graeca-liana,
helix - ivy, Vitis silvestris - vine, Humulus lupulus
- hops, clematis vitalba - forest
is why it is similar to a subtropical forest .
Other rare species are to be found on the sandy
soil: sand bindweed (Convolvulus persicus), sand
crocus (Merendera sobolifera) and tendril (Ephedra
In the southern part of the Caraorman forest impresive
oaks can be seen, with girth between 4.20 to 4.70
