River
works at Upper Pripiat threaten over 60 %
of
Ukrainian population of the Aquatic Warbler
Upper
Pripait floodplain is one of the key Aquatic Warbler breeding sites in
Europe. According to Aquatic Warbler survey, which is implemented
every year by USPB, the BirdLife partner in the Ukraine, it supports
about 3,5 thousand vocalizing males, or c. 85% of Ukrainian and up to
20 % of European population of the Aquatic Warbler.
Most
of Aquatic Warbler breeding sites throughout Europe are protected,
including key Aquatic Warbler breeding sites in upper Pripiat. A
number of hydrological reserves have been set up here, and
establishment of Pripiat National Park is now in progress. Unfortunately,
approval of Volyn regional programme “Ecology 2010” poses
a real threat to wetlands of upper Pripiat in Volyn region.
Strikingly, the programme is approved by the State Regional Department
on Ecology and Natural Resources of Volyn district.
The
programme has a number of actions which are questionable in terms of
their impact on ecosystems of rivers of Volyn region. But the ones of
highest concern are:
-
“Restoration
of the water regime of Pripiat river at the fragment from Vyzhevy
water scoop to Ljubaz’ lake, river
bed adjustment” (action 2.1.2, total cost of works
8’245’000 UAH) and
-
“Restoration
of water regime of Pripiat river at the fragment from Richitsia
village to Vizhevy water scoop, river bed adjustment”
(action 2.1.6, cost of works 4’986’000 UAH).
Technically,
this will mean deepening more that 80% of the river bed with the use
of excavator from Richitsa village to Lubjaz’ lake within
several years.
The
“restoration” works on the 6 km segment of Pripiat river
from Shchedrogir village to Turia river mouth started, albeit at a
small fragment of the river bed, already in spring of 2004, which is before
the approval of the programme by the Volyn State department for
ecology and natural resources. In the autumn of 2005, after the
official approval, the
deepening of the river bed was implemented on the whole
fragment.
The
wetlands of Upper Pripiat floodplain are monitored by USPB, the
BirdLife partner in the Ukraine, from 1999. The floodplain at
Schedrogir village – Turja mouth section were always very
waterlogged. Sedge mires are stretched along the river and regularly
mown by local people, there are also numerous oxbows.
All this creates very good conditions for nesting of waterfowl.
The sedge mires here are also home for up to 4% of Ukrainian
population of the Aquatic Warbler.
In
May-June 2006, USPB assessed the impact of “restoration of water
regime” at this section of Pripiat. And the results where
horrifying – the whole floodplain was dry, even in depressions
there was no water at the bottom of tussocks.
In the second decade of May 2006, the ground water level at
both upper and lower pools of Schedrogir village – Turja mouth
segment of the Pripiat floodplain was 0,7-0,8 m below the natural
water level of the summer mean water period, which happen here in the
end of July – beginning of August. At the same time, in other
parts of the floodplain of Upper Pripiat, the water level was high, as
it would be expected for this time of year. Deepening of the river bed
resulted in a decrease of the ground water level even at parts of the
floodplain located over 1 km from the river.
The
number of Aquatic Warblers at breeding sites located in affected part
of the floodplain decreased by 5 times in 2006 and there is a
possibility that Aquatic Warblers will not breed here anymore. Other
species of waterbirds, like graylag geese, ducks, coots abandoned the
area, too. The effect observed is very similar to the consequences of
similar works conducted in 2000 at Komarne village – Richitsa
village fragment of Pripiat, an Aquatic Warbler breeding site at that
time. Deepening of the riverbed there led to transformation of
wetlands along the river – wet meadows dried out and vegetation
degraded. This resulted in abandonment of the site by the Aquatic
Warbler as well as made the meadows unsuitable (too poor) for grazing.
Deepening
of the riverbed, is in fact, hidden drainage. And, therefore, goes
against national legislation of the Ukraine, and international
agreements which Ukraine ratified. The floodplain in the fragment
planned for “restoration” works is almost entirely
protected as hydrological reserves of regional significance, part of
the floodplain is also a Ramsar site.
