first three institutions (RZGW, WZMiUW and BNP) belongs the implementation of
WFD, communes are mostly responsible for the maintenance of ditches and minor
rivers and streams and WFD, although should, is not directly considered.
4.3 Climate Change, Water Management and Ecosystems
'
Response
Climatic change impacts to the ecosystems of the Biebrza Valley, although already
de
ned as a challenge for valuable wetlands in NE Poland (Grygoruk et al. 2014a ;
Ignar et al. 2011 ), has hardly been anticipated so far neither in the environmental
conservation management in the basin of the river Biebrza nor in the Water
Framework Directive implementation in this area. First steps towards the design
and application of climate-adapted management of protected areas of wetlands in
this region were done in the Biebrza National Park, by implementing the HABIT-
CHANGE project (Rannow and Neubert 2014 ) and by preparation of the draft
document
Climate Adapted Management Plan for the Biebrza National Park
(Grygoruk et al. 2013b ). Main
findings of the project pointed out that the majority
of climate-related threats for valuable wetlands result from the quantitative altera-
tions of water cycle, either as a direct result of naturally evolving hydrological
processes (increasing frequency of summer
flooding, ongoing decrease in summer
sums of precipitation, increasing frequencies of extremely high summer rainfalls) or
indirectly, as the reaction of stakeholders on these processes (Grygoruk et al.
2014a ).
In order to attempt the assessment of whether the actions implemented re

WFD are capable to deal with the prospective de
ned climate change stressors, the
DPSIR matrix of general feedback loops was developed. Such an approach was
proven to be a suitable tool in detecting WFD-implementation-related risk assess-
ment (Borja et al. 2006 ). It anticipates climate-related pressures to habitats (after
Grygoruk et al. 2014a ) that induce the state of ecosystems, to which the negative
impact to be considered in the water management was de
