VCA Proposal Green Circle Bee-landscape A. Executive Summary

A sustainable economy with a climate and natural resource-neutral Heineken brewery as its icon, and a pleasant living environment in the region of Zoetenryoude in The - these are the ambitions to which "Green Circles" is dedicating its efforts. lt does so by building on the cradle-to-cradle principle, but taking this principle a crucial step further by creating co-operation between nature and people. "Green Circles" is seeking to make solutions for a circular economy more sustainable by taking advantage of services provided by the ecosystems in the landscape. Such solutions not only make the use of energy, water, raw materials and transport less dependent on natural resources, but also create added value to the environment of the people in the region. "Green Circles" is an umbrella programme under which dedicated social networks, the Green Circles, are established such as for Water (Security), Sustainable Transport, Sustainable Agriculture, Energy, and the Green Circle for establishing a Bee-landscape. "Green Circles" is an inítiative of multinatíonal Heineken, the Provincial Government of Zuid-, and research institute Alterra Wageningen UR. lt is keen to attract and gain the commitment of other societal actors necessary for achieving these ambitions and setting a world-class example.

Pollinators are a key component of global biodiversity, providing vital ecosystem services to crops (apples (Heineken is a big cider producer)) and wild flowers. There is clear evidence for recent declines in both wild and domesticated pollinators, and parallel declines Ín the plants that rely upon them. Habitat loss and fragmentation, agrochemicals, climate change and the interactions between them have been identifíed as potential causes of pollinator loss. Pollinator declines can result in loss of pollination services, which have important negative ecological and economic impacts that could significantly affect the maintenance of wild plant diversity, wider ecosystem stability, crop production, food security and human welfare.

The Green Circle Bee-landscape aims at the return of bees, bumblebees, other pollinators and butterflies to the landscape through the creation of a regional, cohesive network of ecologically diverse grassland areas. We do this by developing a social network of dedicated actors, helping them to create a common vision and supply them with information how to design in cooperation an ecologically sustainable networks for pollinators. This resulted ín the adaptation of the management of business sites, municipal parks, private gardens, field margins and road verges. 'Biodiversity at the Brewery' is among the first projects contributing to this Bee-landscape , in which we transformed the brewery terrain of Heineken to increase biodiversity, without disrupting the industrial character of the site.

VCA Proposal Green Circle Bee-landscape 2 This pollinator network called the Bee-landscape is unique and innovative by its size, the involvement of so many different stakeholders including business and citizens, and the high degree of self-governance, based on the interaction between the social and ecological networks. ln this governance modelthere is an important role of information about the ecology of bees and other pollinators, the importance of a high level of species diversity to provide a reliable pollination service, and the need to create sites large enough for sustainable pollinator communities and interconnected ín a network to create a resilient ecological network for pollinators. This information connects people in a common aim and shared responsibilities to adapt their environment for better ecological quality. This resulted in a social network encompassing actors from science, government, businesses, societal organisations and area managers working side by side with farmers, entrepreneurs, beekeepers and citizens. This broad societal cooperation is unique in The Netherlands.

Together they aim to enhance the number of honeybees that survive the winter, push back the decline of the bumblebee and wild bees to below 10o/o by providing enough food and nesting opportunities, at the same time increasing the attractiveness of the landscape by adding colour, and reducing the use of chemical pesticides. This should secure the future-proof pollination of agricultural crops and wild plants.

The Green Círcle Bee-landscape lies in the municipalities of Zoeterwoude Leiderdorp, Zoetermeer, Leiden, Alphen, and .

Zuid-Holland is a province in the midwestern of the Netherlands. lt has a population of just over 3.6 million and a population density of about 1,300/km2, making it the country's most populous province and one of the world's most densely populated areas.

The Green Circle Bee-landscape is situated in a strongly urbanized area in between the larger cities of Leiden, Alphen a/d Rijn and Zoetermeer, with small villages, industrial sites, recreational areas, and a Natura 2000 reserve'De Wilck' in between, Alphen a/d Rijn and Leiden are situated along a former main branch of the River , called Oude Rijn, in a typical Dutch fen landscape: low-l$ng marshy land that has been converted into a mosaic of pastures and arable fields. The western part of Leiden city finds itself on the "Old Dunes", a former dune area that originates from the Holocene.

82 Area Management

We work at establishing a new format for cooperative governance by stimulating a social network in which local and provincial authorities, companies, societal organizations, scientists, individual citizens and area managers develop a shared responsibility for creating a common ambition and designing a sustainable ecological network for pollinators, self-monitor the achievements and if necessary adjust the work in progress to better meet the goals of the bee-landscape. The main drivers of this process are information on what is needed in the landscape to create sustainable conditions and the shared motívation and trust developed by the network partners. This combination of self-governance of a social-ecological network and the large extent makes the Bee-Landscape new for The Netherlands and possibly unique in the world.

VCA Proposal Green Circle Bee-landscape 4 Critical to this cooperation is the shared feeling of urgency for action to halt the loss of honeybees and wild pollinators, and that it is through only large scale and long term cooperation that this can be achieved.

Already entered into the Green Circle Bee-landscape social network are: . The municipalities in the region, i.e. Alphen a/d Rijn, Zoetermeer, Leiden, Leiderdorp and Zoetenruoude, . The province of Zuid-Holland, . The regional water management body ('hoogheemraadschap') Rijnland, . Natíonal water and infra management authority Rijkswaterstaat . Heineken Nederland B.V. and AkzoNobel B.V. representing business in the region . Alterra, the national biodiversity centre Naturalis, the Vlinderstichting and the Stichting EIS representing science . The beekeepers society Leiden en omstreken, . The non-governmental organizations lVN, ANV de Groene Klaver, Zuid-Hollands Landschap, . Societal organization Fonds 1818.

Mrs. Laila Driessen, mayor of Leiderdorp is chairwoman of the Green Circle. The Stichting Wijk en Wouden provides the secretariat services, co-financed by the Province of Zuid-Holland and Fonds 1818.

Buildino two different networks The basis of the self-governance is the building of two interacting networks o The physical network of inter-connected bee-friendlv areas which offer sustainable conditions for pollinators even under climate change regimes, where honey can be sustainably harvested, and which are perceived by citizens as a pleasent envíronment for living and working; o The social network of oeoole. bus s and reoional oroanisations that together takes responsibility for the realization of the physical network of bee- friendly areas. This network is driven by the shared feeling of urgency and the cooperation within the network is by information on sustainable conditions for pollinators (size of core areas and connectivity), including feed-back information on progress.

These two networks are closely interlinked and mutually depend upon each other: without a social network no regional network and vice versa. On the one hand, initiators for bee-friendly areas will work together to create 'bed and breakfast' areas for pollinators or to connect such 'areas and thereby realize the regional network. On the other hand, the required size of bee-friendly areas and the maximum distances

VCA Proposal Green Circle Beelandscape 5 between them will stimulate visitors and neighbouring actors to join the social network and work together to reach the collective goal.

The social network: regional initiatives To realize a regional network for pollinators the current social-ecological network needs further extension. A number of local councils and governments, businesses and other societal organisations are already adopting a bee-friendly management for their terrain. Other actors are in the process of finding partners to realize a 'bed & breakfast' area or securing finances. The locations of initiatives undertaken by the members of the social network at the end of 2014 are visualized in Figure 2 showing the present contours of the regional network for pollinators. This map will be used to pinpoint suitable locations for further initiatives, where desirable or most effective to strengthen and extend the regional network.

The regional network for pollinating insects A regional network which is sustainable for pollinating insects like wild bees, bumble bees, honey bees and hoverflies consists of two elements: a) larger'bed & breakfast'

VCA Proposal Green Circle Bee-landscape 6 areas and b) smaller landscape elements (or green infrastructure) that connect the 'bed & breakfast' areas.

a A 'Bed & breakfast' or B&B is an area where sufficient food is available year- round and which has enough nest sites to sustain populations of pollinators. Relatively large areas are needed 1) to accommodate variations in climatic and local weather conditions, and 2) to harbour a varied community of different species of pollinators; a Green infrastructure: the landscape elements between B&B areas that provide food, shelter and sometimes also nesting sites. These elements are too small to function as B&B as they cannot maintain viable populations. However they connect B&B areas making these more robust to external negative impacts: pollinating insects can migrate to new areas or re-colonize former B&B area that became unsuitable due to e.g. extreme weather or diseases. Also they help insect populations to move over to new areas following climate change. Road sides, ditches and small left-over areas are examples of components of this green infrastructure.

A large number of actívities, programmes and projects have started or are due to start, see Annex L

C. Rapid Biodiversity Assessment and SWOT Analys¡s

C1 General biodiversity overuiew

The central part "Land van Wijk en Wouden" carì be characterized as a typical Dutch meadow landscape, used for dairy farming, and laid out in a pattern of long strips due to former peat harvest. Land van Wijk en Wouden is surrounded by lakes (Kagerplassen) and a dense urban area: Leiden, Leiderdorp, , Zoetermeer and -Voorburg.

Low-lying grassland areas on peaty soils traditionally harbour globally unique meadow bird communities, with internationally important populations of species like Black-tailed Godwit, Lapwing and Common Redshank. Wijk en Wouden is one of the core areas in The Netherlands for these meadow birds. ln the centre of Wijk and Wouden lies the Natura 2000 area "De Wilck". Here more than 100 breeding pairs of Black-tailed Godwit (Limosa Limosa) can be found. Despite much research and many policy measures at the local scale, meadow bird populations still decline in the area.

Figure 4: Kochjespolder with flowering Marsh marigold (Caltha Palustris)

VCA Proposal Green Circle BeeJandscape 7 ln Wijk en Wouden most of the flower-rich meadows have disappeared. A recent study based on a 25-year long database shows that wild bees and the flowers that they pollinate are declining rapidly (80% loss) in the Netherlands and United Kingdom (Biesmeijer et al. 2006). Only a small number (but very important) of small flower-rich, herbaceous meadows survived in Wijk en Wouden.

Figure 5: Lakerpolder with pink Ragged Robin (Silene flos-cuculi)

lntensification of dairy farming in these areas, involving widespread land consolidation, drainage, fertilisation and mechanisation has increased stocking densities and changed the area into structurally uniform, monoculture grasslands which are mowed earlier in the year, more frequent and faster. This development has caused severe declines of biodiversity in the formerly herb- and flower-rich meadows. Worldwide, conversion of land cover has been extensive, typically to support agriculture. These shifts, along with trends in using synthetic fertilizers rather than rotations of nitrogen-fixing cover types (e.9., clover, alfalfa) that are beneficial to bees, challenge bees to find sufficíent floral source. Understanding how land-use change affects honeybees and other pollinators is one element needed to inform decisions affecting development of sustainable management paradigms for delivering ecosystem services to society.

In the eastern part of Wijk en Wouden lies Bentwoud. Bentwoud is a forest in the making, at the clay of a reclaimed section of land between Zoetermeer and Alphen a/d Rijn. The new (nature and recreational) location will number around 3 million trees on approximately 1000 hectares. lt will be a varied area with woods, water features, marshes and grassy meadows, intersected by bicycle and hiking paths.

C2 Focus on Bees and Hoverflies

ln 2014-15 a survey was carried out at. 14localities to assess the insect diversity in the region. lt revealed the occurrence of 71 species of bees and 83 species of hoverflies (Reemer 201 5):

Several species have been found that are rare in this part of the Netherlands or even on the Red List for lnsects, such as Andrena grav¡da, Andrena cineraria, Megachile ligneseca, Hylaeus pictipes and Sfe/rs breviuscula.

The location with the highest diversity of bee species was found to be 'Het Bentwoud': 38 species. The Bentwoud is a forest in the making. Here the bee species Andrena gravida was found, which had become extinct in the western part of the Netherlands.

Numbers 2 and 3 on the list of most bee species-rich locations are the business site of Heineken Nederland BV (in Zoetenrvoude Rijndijk), and the Archeon (in Alphen a/d Rijn). This is remarkable, as both areas do not have the function of nature reserye. Since two years the business site of Heineken Nederland BV and Archeon area have been planted with semi-natural, flower-rich vegetation and consciously managed for biodiversity. Apparently with success as the bee species Sfe/is breviuscula was found at Archeon, the second discovery in the province of Zuid- Holland.

With respect to hoverflies other locations core high, in particular Elfenbaan (47 species), Oostvlietpolder (45 species) en de roadsides of the N1 1 (44 species). All

VCA Proposal Green Circle BeeJandscape o these areas are relatively wet. Where bees are found predominantly in open and dry areas, hoverflies prefer more forested and wet terrain.

This survey will serve as the baseline assessment for comparison with the outcomes of future surveys. The first one is scheduled for 2018.

ln addition there are data on winter mortality of honeybees. Annual mortality varies strongly between years: after a few years of nearly 30% it decreased significantly but since 2014 it rises again to nearly 20o/o of the population.

C3 SWOT analysis a) Strenoths

Broad coalition (social network) supporting the quality stimulus of this open Iandscape : o Land van Wijk and Wouden is an ínitíative of farmers and other residents that started in 1999, asking for more attention to be paid to the developments in their area. An area committee(gebiedscommissie) was established , which seeks to promote and protect the entire area as one unit. The area committee is a platform including 7 municipalities, the district water board and a number of NGOs (agri- environmental associations, the LTO farmers' organization). This composition ensures intensive interaction between cities and rural interests. o The Green Circle Bee-landscape brings together a wide range of different actors from science, government, business, societal organisations and area managers who will work side by side with farmers, entrepreneurs, beekeepers and citizens and the 'Gebiedscommissie'of Wijk en Wouden. The chairwoman of the Gebiedscommissie Wijk en Wouden (also Mayor of the municipality of Leiderdorp) is also the chairwoman of the Green Circle Bee- Landscape. This broad societal cooperation will be unique in The Netherlands. o A program (bottom up) based on a shared vision and with many stakeholders has a high political feasibility.

b) Weakness . Several municipalities have decreased there funding of the Wijk en Wouden organization due to the economic crisis. o Further intensification of dairy farming o There are no clear bounderies of the "bee-landscape".

c) Opportunities (l A lot of investments are made in the realisation of recreational areas (Bentwoud, Noorder AA). Habitat management for bees can easily be incorporated.

VCA Proposal Green Circle Bee-landscape 10 o The cooperation of the citíes of Leiden, Zoetermeer and Alphen in this Green Circle gives good opportunities for crowd-funding in the neighbouring rural areas. o New forms of funding are possible (and currently being prepared) in this new social network. o Science (Wageningen University and Naturalis, the National Biodiversity Centre) and almost allthe landowners work together in the implementation of new concepts for habitat management for bees.

d) Threats o Risk of further urbanization of the area Wijk en Wouden. The main threat to the area comes from the towns of Leiden, Alphen and Zoetermeer, which may try to nibble at the edges of the open area by building into it. o Risk of further intensification of dairy farming by reforms of European Union (EU) Common Agricultural Policy (CAP) and EU milk quota abolition.

C4 Approach for 2016 and thereafter

The action plan for 2016 contains the following components

Eco-profiles (see Annex ll) defined for each location, helpdesk established for area managers, and training courses for managers and gardeners.

a Start of a public campaign focusing on gardens(citizens) and politicians ; funds from Fonds 181 and the province of Zuid-Holland are available to finance the planting of bee-friendly plants and bee-hotels in citizen gardens; garden centres will supply interested persons with plant material.

o Start of a crowd-funding action to establish green ribbons in the agricultural landscape where the decrease of wild bees and bumblebees is largest.

a Development of a 4th eco-profile for green ribbons in cities and urban areas

D. Expected Conservat¡on lmpact and Stakeholders

D1 Biodiversity - lmpacts

At three locations a bee-friendly management regime (B&B) was adopted since 2014 based on scientifically developed eco-profiles (Annex ll) and advice received from the Bee Helpdesk. The results of the baseline assessment in 2015 for these three locations demonstrate that potentially a significant increase in the number of bee species and hoverflies can be expected over the years to come throughout the ecological network. Such an expectation can also be based on the considerably improved conditions for pollinator population persístence and recovery based on the increase of area and connectivity of the suitable sites, considering the large amount of literature supporting the relationship between species diversity and size and connectivity of ecological networks. There is recent scientific literature suggesting

VCA Proposal Green Circle BeeJandscape 11 that an increase in species diversity at sites brings along an increase in the pollination efficiency and reliability.

Because there does not exist a systematic monitoring of wild bees and hoverflies linked to management regimes so far in the Netherlands, there is no evidence base for predicting the impact of the creation of the Bee Landscape on the species list for the whole region. However, the finding of a number of rare species is encouraging.

Expectations regarding honeybee mortality fully depend on whether agreements can be made with allterrain and site managers in the region on the use of neo- nícotinoids and provision of year-round feeding opportunities. ln view of the planned actions (public campaign, bee-friendly gardens, flowerstrips in the rural area, new management plans in favour of bees, new bee-habitats, agreement about the use of pesticides) starting in 2016 and assumption that all terrain-owníng organizations (ranging from municipalities and province to citizens and farmers) are joining the initiative, it is expected that the annual bee mortality will decrease significantly in the cities and rural areas.

D2 Stakeholder management and communication ln 2016

o We start a public campaign and discussion for two years focusing on citizens and schools (bee-friendly gardens), municipal politicians (to finance bee-friendly municipal habitat management plans) financed by Fonds 1818 and the Province of South Holland. o ANV Groene Klaver (farmer-environmental organisation) and Green Circle start crowd-funding for colourful ribbons in the rural landscape (together with the farmers). o Naturalis/Stichting EIS and Wageningen University/Alterra prepare a fourth Eco-Profile regional green infrastructure for bees and butterflies in the city. o Naturalis and IVN make an inventory card "bee identification for children" and an education program for schools. o Alterra prepares and provide workshops and courses to gardeners, land managers and politicians. o We continue with our Helpdesk for land managers. o We will organise an exhibition in Naturalis): A2bout Bees. o We will launch a Facebook page and continue two websites: httos ://www. face boo k. co m/bltent ndebuu rt www.fondsl 8 I 8. nl/biienindebuurt. www.qroenecirkels.nl/nl/qroenecirkels/.../Proiect-Biienlandschap.htm o We make every month a news letter: https://www.odwh. nl/dsresource?obiectid=a8557e32-976 1 ...

VCA Proposal Green Circle Bee-landscape 15 Annex ll

Looking through the lens of Eco-profiles

Every bee and hoverfly species requires specific conditions to its environment in order to exist, grow and reproduce. However, species that have comparable demands with respect to habitat, food and nesting sites, can be classified into groups, so-called eco-profíles. The hundreds of pollinating insects that potentially could occur in the region of the Green Circle Bee-landscape have been grouped into three different eco-profiles:

a Eco-profile 'Bumblebee': comprises species that require the presence of trees and bushes interspersed with grassy lawns that have some patches of bare soil o Eco-profile'Hoverfly': comprises species that require both dry and wet grasslands with open spots Eco-profile 'Pioneer': comprises species that prefer open areas with a vegetation of rising herbs alternating with patches of bare soil.
