Annex 1
Preparation of a single integrated management plan for the Wadden Sea World
Heritage Site
1. Introduction
As reflected in the decisions of the World Heritage Committee (WHC) in 2009, 2011, and
2014, the Wadden Sea Plan 2010 is the overall framework and structure for integrated
conservation and management of the property as a whole and coordination between all three
States Parties. The WHC also concluded that comprehensive protection measures are in place
within each State party.
The World Heritage Committee 2014, requested the States parties “to develop a single
integrated management plan for the entire transboundary property … and to consider the
options to strengthen the effectiveness of implementation of coordinated management within
the property”.
Since the inscription of the Wadden Sea World Heritage site in 2009 and the extension in
2014, much has been achieved to intensify the cooperation to protect and maintain the
Outstanding Universal Value (OUV) of the property. As a result of the World Heritage site
designation, the agenda of the Trilateral Wadden Sea Cooperation (TWSC) has been
broadened and there are now many new opportunities to strengthen nature conservation - the
fundamental purpose of the cooperation – and to increase civic pride, raise awareness,
increase support and practical involvement, and achieve socio-economic benefits.
In close cooperation with and support of many stakeholders, a wide variety of strategies and
plans have been developed including, amongst others, the Wadden Sea World Heritage
Strategy and the roadmap to involve strategic partners, the Wadden Sea World Heritage
Brand Paper, the Sustainable Tourism Strategy and Action Plan, the Wadden Sea World
Heritage Education Strategy , the Flyway Vision, the Framework for Sustainable Fisheries,
the Alien Species Management and Action Plan (in development), the Climate Change
Adaptation Strategy, the Particularly Sensitive Sea Area Wadden Sea Operational Plan, the
Trilateral Monitoring and Assessment Programme, the Seal Management Plan, and the
Trilateral Communication Strategy,
The development of a single integrated management plan, as requested by the World
Heritage Committee, will help to further strengthen the ongoing efforts in harmonizing
management of the Wadden Sea as one property in an integrated approach. The management
plan shall provide a clear overarching framework that can be easily read and understood by
stakeholders and the general public. This concerns especially the definition of roles and
responsibilities of the TWSC, site managers and key stakeholders in implementation of plans
and strategies.
Thus, the single integrated management plan strengthens the Trilateral Wadden Sea
Cooperation, enhances understanding of joint management, and creates ownership and
commitment among stakeholders to protect and maintain the OUV.

13th Trilateral Governmental Conference 2018

Leeuwarden Declaration

2. Objectives
The single integrated management plan for the Wadden Sea World Heritage Site provides an
umbrella to integrate existing trilateral strategies and plans without losing their commonly
agreed content, while taking into account existing regional and national management systems,
which can be easily read and understood by stakeholders. It also provides a clearer picture of
resources needs and transparency how the management system functions. In this respect, it is
of added value for the Trilateral Cooperation.
The overarching objective of the single integrated management plan is to demonstrate how
the effectiveness of coordinated management can be strengthened with the aim to maintain
and preserve the Outstanding Universal Value of the property and protect its natural values
and its integrity on the basis of the Guiding Principle.
The specific objectives are
1. Providing a coherent overview on how trilateral management is done jointly, also
taking into account the local level, to strengthen the protection of OUV and integrity
as shared responsibility.
2. Enhancing ownership and commitment of stakeholders on all levels in management
of the property as one entity and supporting the countries in implementation of
trilateral strategies and plans on the ground.
3. Striving towards a further harmonization of management on the ground and
strengthen the effectiveness of implementation of coordinated management while
taking into account the regional management systems and regional differences.

3. Content
The single integrated management plan for the Wadden Sea World Heritage property will
focus on overarching issues to be managed with priority and in a consistent way across the
property to maintain the OUV and protect the area’s natural values and integrity.
The single integrated management plan is a rolling plan and will be evaluated regularly by the
Wadden Sea Board. Therefore, the contents will be adapted to management requirements of
the TWSC with the support and participation of all key parties involved in implementing the
plan.
Criteria for the selection of the issues to be addressed
1. Main and prior management issues at trilateral level (identified in particular from the
Wadden Sea Plan, recent Ministerial Conference Declarations, and existing strategies
and action plans),
2. Urgency to enhance management effectiveness trilaterally,
3. Management and protection requirements with regard to maintain and protect the
OUV (as reflected in the Statement of OUV, relevant Committee Decisions and in the
Periodic Reporting).

13th Trilateral Governmental Conference 2018

14

Leeuwarden Declaration

The starting point for the further development of the single integrated management plan will
be a preliminary structure agreed by the Wadden Sea Board. The content will reflect the
current priorities of the TWSC, but contents and priorities may be adapted during the process.
A flexible approach is envisaged.
The single integrated management plan will be a concise and short document (maximum of
40 pages) and contribute to make the complexity of World Heritage management operational.
It should be easy to read in order to better connect to the people on the ground. It should in
general follow WHC and the International Union for Conservation of Nature (IUCN) advice
on World Heritage management plans.

4. Timeline
The development is a trilateral process with involvement of site managers and stakeholders
from all Wadden Sea regions and the IUCN. The function of the single integrated
management plan as a rolling plan reflecting the main priorities of the trilateral management
has to be considered in its preparation.
The aim is to develop the single integrated management plan in the period 2018 – 2020 with a
finalization and implementation in 2021 to deliver a proposal for final adoption at the 14 th
Trilateral Governmental Council Meeting in 2022.

Wadden Sea Strategy on Education for Sustainable Development and World Heritage
Interpretation (Summary)
Introduction
Building upon a network of people and activities evolved over decades, the “Wadden Sea
Strategy on Education for Sustainable Development and World Heritage Interpretation” aims
to provide a trans-boundary framework for environmental education and interpretation in the
entire Wadden Sea. It stands for ONE Wadden Sea and builds on the numerous local, regional
and national activities in this field. It is supposed to provide an umbrella to promote the
Wadden Sea’s Outstanding Universal Value (OUV) in an international and interdisciplinary
approach. Filling the strategy with life – from the local to the trilateral level – is a common
responsibility.
The strategy has been developed as part of the work of the International Wadden Sea School
(IWSS). Much has been contributed by the Trilateral Network Group Education, the members
of which represent Wadden Sea education and interpretation at national and regional levels,
and by the Common Wadden Sea Secretariat. The work was supported by the Trilateral
Wadden Sea Cooperation and its Wadden Sea Board.
The strategy links and contributes to implementing other important strategies for the Wadden
Sea, namely the overall World Heritage Strategy and the strategy for sustainable tourism. It
also contributes to the UNESCO Programmes for “World Heritage Education” and
“Education for Sustainable Development”
Our Vision for the Future
It is our joint vision that in the future…
People who live, visit or work in any part of the Wadden Sea World Heritage region
are aware of and appreciate the OUV and the unique landscape. They are committed
to preserving these globally important assets for the benefit of present and future
generations and for all humankind.
Environmental education and interpretation provide access to the understanding and
appreciation of the Wadden Sea World Heritage Site and its global importance. Highquality information and nature, landscape and culture experiences ensure outstanding
opportunities for all age groups to learn about, experience, enjoy, and support the
protection of the Wadden Sea.
Local, regional, and trans-boundary, as well as governmental and non-governmental
offers complement each other, and committed partners actively cooperate at a
national, trilateral and international level. All education and interpretation activities
support the integral protection of the Wadden Sea as an ecological entity and the
ecological requirements of its common World Heritage status.

Leeuwarden Declaration

Our Objectives and Measures – How the Vision becomes Reality
Three joint objectives set out how we want to achieve the vision:
Competent multipliers: All stakeholders of Wadden Sea education have a
transnational understanding and appreciation of the Wadden Sea World Heritage Site,
its OUV and its protection in a trilateral and global context.
High-quality information: Comprehensive holistic information and education offers
provide consistent communication of the OUV throughout the Wadden Sea Region
and beyond.
Outstanding person-to-person communication: Guided nature interpretation offers
provide authentic experiences of the diversity, dynamics and beauty of the Wadden
Sea World Heritage Site for everyone.
Thirteen measures at the national as well as at the trilateral level are expected to achieve the
objectives and to realise the vision in the long term. At the trilateral level, three measures
comprise networking and service activities targeted at multipliers of Wadden Sea education as
well as providing multilingual education resources focussing on the World Heritage Site. Ten
measures at the national level range from training programs for various audiences, to
operating visitor centres and other information systems, numerous guided tours e.g. for the
public and for classes, to online and offline information and education material.
Audiences
Our approach to Wadden Sea education and interpretation from the local to the trilateral level
addresses various target groups in the framework of formal, non-formal and informal
learning.
Schools of all kinds: The audience for “formal learning” includes school classes,
schools and other formal learning groups, including schools of applied sciences and
universities;
Stakeholders: The main audience for “non-formal learning” are multipliers of
Wadden Sea World Heritage education and interpretation, such as visitor centres,
NGOs, nature guides and youth groups engaged in extracurricular learning activities,
such as junior rangers;
General public: The main audience for “informal learning” is the general public – i.e.
local inhabitants and guests (tourists on holidays, including day-trips).
Implementation
The implementation of Wadden Sea World Heritage education and interpretation is a shared
responsibility and common task of the signatories of the strategy. They include public
authorities, NGOs, and other stakeholders at the national and trilateral level, while also being
open to welcoming more supporters.
The implementation at the trilateral level – according to a trilateral work programme further

Leeuwarden Declaration

specified in annual work plans – is a core task of the Trilateral Wadden Sea Cooperation and
realized by the IWSS together with its network of education centres with guidance provided
by regional representatives, the Wadden Sea Board and the Task Group World Heritage.
Implementation at the national level follows national work programmes – existing or future
measures of the three Wadden Sea countries and their different regions – by public as well as
private partners, such as municipalities, provinces, National Park administrations, NGOs,
visitor centres, schools, etc. The regional networks identify representatives to support and
advise the trilateral work programme.

Trilateral Wadden Sea Swimway Vision

PROPOSAL FOR A TRILATERAL WADDEN SEA SWIMWAY VISION 2018-2024
Introduction
The Wadden Sea is one of the world’s largest coherent intertidal wetlands. With more than
150 fish species recorded to date, including 13 freshwater species, the fish community of the
Wadden Sea is exceptionally diverse. The populations of many fish species in the Wadden
Sea have steeply declined in recent decades, and causes of these declines are only partly
known or understood.
Basic understanding of essential processes and functional pathways is in many cases still
missing, hampering effective and efficient fish conservation. For this reason, Danish, Dutch
and German fish experts developed conservation objectives for fish –the so— called Trilateral
Fish Targets, which were adopted as part of the Wadden Sea Plan at the Trilateral
Governmental Conference in 2010:
1. Viable stocks of populations and a natural reproduction of typical Wadden Sea fish
species;
2. Occurrence and abundance of fish species according to the natural dynamics in
(a)biotic conditions;
3. Favourable living conditions for endangered fish species;
4. Maintenance of the diversity of natural habitats to provide substratum for spawning
and nursery functions for juvenile fish;
5. Maintaining and restoring the possibilities for the passage of migrating fish between
the Wadden Sea and inland waters.
Based on the agreement at the Trilateral Governmental Conference in 2014 Denmark,
Germany and the Netherlands decided to work on the further implementation of these
Trilateral Fish Targets. It was decided to advance these targets by developing a Trilateral
Wadden Sea Swimway Vision. The Vision was developed in 2017 by a trilateral coordination
group with contributions of research institutes, nature management organizations and
authorities with a view to obtaining a signed commitment of governments and stakeholders at
the Trilateral Governmental Conference in Leeuwarden, Netherlands, in 2018.

The Trilateral Wadden Sea Swimway Vision 2018 - 2024
Implementing the Trilateral Fish Targets is the main goal of the Vision, and the aim is to
provide an overarching Swimway approach –an umbrella- for all kind of initiatives related to
achieving the targets. The Vision is based on four pillars: research and monitoring; policy;
measures; stakeholder involvement, communication and education.
Research and monitoring
Present knowledge of the factors driving fish population dynamics in the Wadden Sea is in
many cases largely insufficient to establish measures for improvement. A Swimway research
approach, covering issues such as connectivity, predator-prey relations, ecophysiology and
habitat-species relations is currently under development. The Vision will link to the Trilateral
Research Agenda also currently under development, as well as to the findings of the Trilateral
Task Group on Climate Change, the relevant part of the TWSC Quality Status Report 2017,
and should fit in and be complementary to national research agendas. This research approach
will provide important information that helps to develop meaningful and robust indicators to
assess progress towards the Trilateral Fish Targets.
Policy
Policy objectives for fish in the Wadden Sea are formulated at the European, trilateral,
national and regional levels. Within the Vision it is aimed for making an inventory of existing
policies and regulations relevant to the Trilateral Fish Targets at the European, trilateral,
national and regional level and to analyse their contribution to the realisation of the these
targets. Following the analysis the need for additional actions could be identified.
Measures
At various locations conservation measures have already been carried out or are planned with
a view to improving living conditions for and to mitigate threats to fish. It is important to
create a comprehensive overview of these measures to evaluate their effectiveness and to
identify how they may contribute to the Trilateral Fish Targets. This information will be
combined with the analysis of the bottlenecks along the migratory routes to gain insight into
where measures might be effectively developed while taking into account relevant EU
legislation and adhering to the principle of careful decision-making.
The implemented Vision will add value in sharing data and information between the three
countries, defining best practices and applying research outcomes to develop measures and
improve fish conservation. The information will be provided clearly and coherently and
discussed with stakeholders.

Stakeholder involvement, communication and education
To gain commitment from all stakeholders, raising awareness, activating practitioners and
facilitating knowledge exchange are important goals of the Swimway vision. Four successful
national case studies/initiatives, already in progress, are used as showcase to help to illustrate
the importance and success of the Vision. Four best practice activities have been selected:

Leeuwarden Declaration



Global: Swimways of the World;



Denmark: use of citizen science in fisheries, with focus on recreational fisheries, the
“Key Fishermen’s Project”;



Germany: Masterplan Ems 2050;



The Netherlands: working together with commercial fisherman to tag migratory
species using the Wadden Sea.

The vision focuses on involvement of stakeholders who have direct or indirect impacts on fish
through their activities, such as researchers, commercial and recreational fishermen, water
authorities, relevant governmental agencies and non-governmental organizations (NGOs). A
communication plan as part of the overall trilateral communication will be developed.
Project organisation
The Wadden Sea Board will be responsible for the coordination of the vision. The three
countries will work together and convey expertise, capacity and resources on a project based
approach for the implementation. A trilateral steering group may carry out the overall
management of the programme and consist of representatives from Denmark, Germany and
the Netherlands. For coordination, facilitating collaboration, fundraising and project
development, a project leader may be appointed. The Common Wadden Sea Secretariat
(CWSS) may serve as a base for a project leader. The Vision may be implemented after the
conference and is envisaged to run for 6 years.

Annex 4
Trilateral Management and Action Plan Alien Species (MAPAS)
Trilateral alien species activities in the UNESCO Wadden Sea Property
The worldwide increase of alien species, boosted by human activities, has the potential to
negatively impact on the Wadden Sea UNESCO World Heritage property. The Road Map
Wadden Sea World Heritage Strategy 2014-2020 foresees the development of a trilateral
management and action plan on alien species for increased insight, awareness, control and
management of invasive alien species2 in the Wadden Sea Area.
As agreed upon at the 12th Trilateral Governmental Conference on the protection of the
Wadden Sea in Tønder (2014) (§ 35, Tønder Declaration; CWSS, 2014), the trilateral
strategic framework for dealing with alien species in the Wadden Sea should be further
developed towards a trilateral management and action plan on alien species (MAPAS), taking
into account existing and upcoming legislation and projects by the trilateral Working Group
on Alien Species (WG-AS). The overall objective of the MAPAS should be to prevent threats
from alien species to Wadden Sea´s marine and terrestrial ecosystems and to sustain its
Outstanding Universal Value (OUV) and integrity by preventing, managing or controlling
alien species through a coordinated effort in the trilateral area.
The MAPAS may contain seven strategic elements (Fig.
1). National activities, in line with existing
political and legal frameworks for alien species
treatment, can be integrated into a harmonised
management with a common approach to protect
and conserve the UNESCO World Heritage
property. These national and trilateral activities
should be continued as detailed in the MAPAS.
In addition, several new activities are
recommended in the MAPAS and should be
implemented, where national legislations will

(1-3) Proposed prevention, monitoring and risk assessment measures
Prevention of marine and terrestrial alien species introduction is the first and most effective
strategy to protect the Wadden Sea ecosystem. To increase the effectiveness of measures and
to assist the implementation of regulatory obligations, several additional management actions
should be taken, e.g., a combined pathway analysis for the introduction of alien species to the
Wadden Sea Area, an integration of alien species parameters to the Trilateral Monitoring and
Assessment Programme (TMAP), as well as trilateral sharing of knowledge and data. The risk
analyses should be trilaterally shared.

Alien species means any live specimen of a species […] introduced outside its natural range [...]. Invasive alien
species means an alien species whose introduction or spread has been found to threaten or adversely impact upon
biodiversity and related ecosystem services (EU Regulation No 1143/2014).

(4) Trilateral coordination (Decision making)
The national authorities should remain responsible for alien species management, on a
trilateral level supported by the CWSS. It is proposed to set up a coordination group with
representatives from three countries, similar to the already existing WG-AS, to advise
appropriate common conclusions and measures. Timely communication and information
about (new) detections, spreading and measures would be crucial. To optimize the
effectiveness of decisions made, the coordination group could support, where possible,
national decisions and risk-assessments. Tasks may encompass coordinating information and
citizens science programs.
Proposed main tasks for trilateral coordination
1

Organising and sharing data on alien species records throughout the Wadden Sea Area. Primary actions will
be the harmonization of data arising from national alien species monitoring programmes and their
continuous accessibility e.g., for the Trilateral Monitoring and Assessment Programme (TMAP).

2

Sharing experiences on the development and effectiveness of monitoring, prevention, control and
eradication methods.

3

Streamlining methods and actions (where possible) focused on “alien species in the Wadden Sea” related
trilateral communication, awareness and education, e.g., the introduction of an information (alert) approach
and an agreement on standardized information channels to disseminate timely information.

4

Providing a regularly updated list of alien species in the Wadden Sea based on national data (TMAP), and
making it accessible via the CWSS website.

5

Providing a focal point on the CWSS website to share examples about the effectiveness of prevention,
control and eradication actions that have been done by either of the States in the Wadden Sea.

(5-7) Management measures and evaluation of mitigation measures
More effort should be set to assess the possibilities of trilateral management, eradication and
control measures for application in the Wadden Sea Area. This includes timely sharing of
information on new alien species occurrences, mitigation measures and their effectiveness.
Regular evaluation of the effectiveness of measures is necessary to assess the success of
relevant management actions.
Proposed actions for communication, awareness and education
Communication, awareness and education about alien species in the Wadden Sea should be
streamlined in a cooperative way. The coordination group should foster sharing information
on the effectiveness of national awareness campaigns, but also facilitate e a number of actions
to promote alien species in the Wadden Sea, e.g., by following trilateral communication
examples for target groups of major pathways of aliens.
Conclusion
Cooperation and clear communication channels between the trilateral cooperation partners
enable synergies would make the management of alien species in the entire Wadden Sea Area
much more efficient. Furthermore, the MAPAS could enhance early warning possibilities
within the trilateral Wadden Sea, which would be extremely important for preparedness and
hence reduce vulnerability towards newly arriving species. Finally, raising awareness on the
basis of a common communication strategy would increase the involvement of the general

public and would have the potential to increase the identification of inhabitants and visitors
with the UNESCO World Heritage site.
