Table 13.1 Overview of specific overriding objectives and standards for the landscape func-
tions, quality objectives (for local scale) and indicators for assessing the effects of environmental
measures
Overriding objectives (legally
binding)
Environmental quality
objectives for the district scale
derived from overriding
objectives and planning targets
Generally applicable indicators
for assessing environmental
quality and the effects of
environmental measures
Safeguarding biodiversity
CBD: conservation of
biological diversity,
sustainable use of its
components, fair and
equitable sharing of the
benefits;
Natura 2000/Habitats
directive: conservation
status of natural habitats
and species of community
interest;
Federal Nature Conservation
Act: three primary
objectives include
safeguarding biodiversity,
protection and
improvement of landscape
functions, preserving and
development of aesthetic
landscape functions
Biotope concept of the
landscape master plan;
explanation: the landscape
master plan concretizes
overriding objectives
within a spatially explicit
development concept by
allocating targeted biotope
types
Furthermore, the landscape
master plan provides
information about areas of
importance for preserving
diversity of species and
biotopes that can be used to
establish priorities for
implementation. Especially
the improvement of areas
with international, national
and state wide importance
(e.g. areas for species
protection, Natura 2000
network, Nature protection
areas) is of high priority
Habitate value points;
Difference in value of the
biotope types—status quo
and targeted status after
implementation of the
measure (in reference to
official list of biotope types
in Lower Saxony (NLWKN
2012 )), multiplied by size
of area (similar to
procedures for assessing
the need for compensation
measures within German
impact mitigation
regulation)
Additionally, specific effects
for species protection are
assessed on an ordinal scale
and assigned to biotopes
classified as having special
importance for species
protection
Natural yield
Soil protection directive, soil
thematic strategy,
German Federal Soil
Protection Act, German
Federal Nature
Conservation Act:
maintain natural yields
capacity and soil fertility
by avoiding soil erosion,
requirements for good
agricultural practice
Erosion prevention on all
erosion prone sites;
explanation: Erosion of soil
caused by wind, water and
floods is considered a main
factor for damage to the
natural yields function. The
landscape master plan
points out areas of high
erosion risk (priority areas
to implement measures for
protection against erosion)
Area with measures for
protection against erosion
within sensitive areas
(three level ordinal scale:
little, periodical effects in
lowering/reduction of soil
erosion (+), medium effects
(++), high, continuous
effects in total prevention
of erosion (+++)
