Golf club De Koepel manages a compact 18-hole course stretching over an area of approximately 50 hectares. The course can be found in the Salland region, between the towns of Wierden and Rijssen, and it lies between a railway line and a provincial road. The club does not own the land. The surrounding area is dominated by agrarian operations. There are no nature reserves or National Ecological Network areas nearby, nor does the golf course lie within the Natura 2000 influence sphere.

The first nine holes were constructed by the English golf a…

Nature

The terrain of De Koepel consists of structured woodlands and heath. The majority of the terrain is filled with grasslands like tees, fairways and rough. In between these, woodlands can be found. In 2012, the majority of the bunkers has been renovated and new bunkers have been consructed. The eastern part of the golf course is in use since March 2003. This part of the course has rather young trees forming young woods and clumps. Remarkable is the presence of the small heathfield (between holes 1, 11, 14 and 15). It consists mostly of Calluna vulgaris, but also Erica tetralix can be found. This species is bound to more moist heathlands. The underground of the golf course is built up of oligotrophic sands. The terrain shows several land dunes with accompanying flats and valleys. The biodiversity is characterised by plants of oligotrophic soils, the viviparous lizard and birds of shrubs and meadows.

For the next few years 2017, 2018 and 2019 there is many saw work on the program. It is intended to saw large air tunnels between the holes so there is more air movement. Leading up on when it is no longer allowed useing fungicides in 2020 it seems a good idea to bring more air on te course.

Het golfterrein De Koepel bestaat uit een gevarieerd bos-en heidegebied. Het merendeel van het terrein bestaat uit graslanden in de vorm van tees, fairways en roughs. Daartussen liggen opgaande boselementen. In 2012 zijn een groot deel van de bunkers gerenoveerd en zijn er nieuwe bunkers aangelegd. Het oostelijke deel van de golfbaan is in maart 2003 in gebruik genomen. De beplanting hier is dus nog niet zo oud en bestaat voornamelijk uit vakken met inheems bosplantsoen en jonge boomgroepen. Vrij bijzonder is de aanwezigheid van een heideterreintje binnen het golfterrein (tussen holes 1, 11, 14 en 15). Het gaat om droge (struik)heide, maar plaatselijk komt ook dopheide voor. Dit is een kenmerkende soort voor natte en vochtige heidegebieden. De bodem van het golfterrein bestaat uit voedselarme dekzanden (veldpodzolen en haarpodzolen). In het terrein zijn diverse landduinen aanwezig met bijbehorende vlakten en laagten. De biodiversiteit wordt gekenmerkt door plantensoorten van schralere bodems, reptielen als de levendbarende hagedis en struweel- en weidevogels. This is a positive incentive against fungus.

Voor de komende jaren 2017, 2018 en 2019 staat er veel zaagwerk op het programma. Het is de bedoeling om tussen de holes grote lucht doorgangen te zagen zodat er meer wind verplaatsing in de baan is. In de aanloop op 2020 wanneer er geen fungiciden meer mogen worden gebruikt lijkt het ons een goed idee om op deze manier meer lucht op de baan te brengen. Dit is een positieve stimulans om schimmels tegen te gaan.

These turfgrasses are optimal for the circumstances at this club because:
The of origin poor soil requires a good understanding and use of the right grass species. Chosen species are drought loving grasses which require a small amount off fertilizer and irrigation.

De van oorsprong schrale bodem vraagt om een goede afstemming van de soort op zijn omgeving. Er is daarom gekozen voor het gebruik van schrale, droogteminnende grassoorten die geen overvloedige bemesting en irrigatie vereisen.

This golf facility assesses mowing patterns every: 6 months

This golf facility consults the following individuals / organizations regarding its grassing plan:

  • Klaus Schmitt en partners
  • STRI mr. Conor Nolan
  • Fa. ProGrass

This golf facility is making the following efforts to manage the playing quality expectations of customers:

Activity Description
Establishing clear internal policies for irrigation, fertilization, colour, cutting heights, overseeding etc We have a quality plan which tells the frequency of management.
Promoting the playing quality values of more naturalized turf, particularly fairways and semi-rough yes, by writing in the clubmagazine.
Promoting the financial benefits of presenting sustainable surfaces yes, by clear extension to board and members by the greenkeeping and we communicate this through the quality plan
Improving customer understanding around greens maintenance yes, by communication about activities on website and information signs and we communicate this through the quality plan
Demonstrating the direct relationship between environmental best practice and year round high quality playing surfaces yes, by clear extension to board and members by the greenkeeping. The quality of the golf course has been improved greatly over the years.

Conservation & Enhancement

This golf facility is undertaking the following activities to conserve landscape character:

Activity Description
Allowing seasonal variation of course coloration and texture Discolouration resulting from drought (to a certain extent) and other factors are seen as an addition to the natural quality of the landscape and the quality of the game.
We only irrigate when necessary, so coloration during the summer is accepted
Appropriately matching mowing lines to contours The mowing lines of the fairways and semi-rough are well tuned in to the undulations and different elements of the terrain.
Protection and restoration of historic features Yes, an old sheep pen and an old oak lane are well maintained. Old heather relicts are restored.
Discreet on-course signage and furniture The terrain furniture has been selected with care and is maintained accordingly.
Conservation of specimen trees We preserve historical elements like old trees and tree lines and heath

This golf facility is undertaking the following activities to improve the landscape ecology of the golf course:

Activity Description
Minimizing the amount of amenity grass We have increased the size of natural elements
Increasing the size of habitat patches The surface intensively mowed grass is kept to a minimum. By determining which elements fall outside the game and which are of importance to the character of the natural landscape, only some elements need to be extensively mowed.
We have increased the size of the heathfields and shrub vegetation.

in 2014 we have placed two storks poles. This is done in order to promote the population of White stork(Ciconia ciconia)
Connection of internal habitat patches Where possible, management is expanded or natural elements are constructed. Especially heatherpatches are (re)connected.
We have sowed special herbs in the rough so these are more connected
Connection of patches with external habitats Yes, by connecting shrubs and bushes to the vegetation along the railway, animals can travel to the both sides of the golf course
Creation of habitat corridors yes, along the railway there is a nice stripe of extensive maintained scrub and rough vegetation and by the increased size of natural elements
Avoidance of habitat fragmentation By the increased size of natural elements, new shrubs and botanical rough
Improving and diversifying habitat edges Edges of plant squares contain borders and casings. The borders of habitats are managed according to the management plan

This golf facility is undertaking the following activities to improve the quality of habitats on the golf course:

Activity Description
Creation of botanically rich rough grassland The natural diversity of vegetation is increased by mowing and removal of clippings.
Additionaly we have sowed special herbs in the rough to create a more diverse rough.
Ecologically informed management of scrub vegetation There is multiannual management plan in place carried out on the basis of a cycle. Woodslands now have more shrubs as aditional structure
Promoting species and structurally diverse woodlands yes, for example by creating grooves of branches. The present woodlands have been thinned in order to create more vitality for the remaining trees
Establishment of littoral shelves and marginal vegetation in wetland areas Natural and gentle banks have been realised in different locations in order to stimulate the flora and fauna in water and its banks. The several shallow banks are present that are managed extensively
Maintenance of an appropriate balance of open water and aquatic vegetation The management of the banks and the cleaning of the ditches and water elements are carried out in phases. This allows for continuity of both thin and thick vegetation.
Naturalization of linear habitats A division has been made of intensive and extensive green in order to create a good balance between nature and the game of golf.
Dead trees We allow dead trees to remain in extensively used parts of the woodlands. This increases the value of the woodlands for insects, bats and birds.

This golf facility is undertaking the following activities to conserve and enhance biodiversity on the golf course:

Activity Description
Provision of nesting and nectar for pollinators New plant species have spontaneously appeared, providing a colorful view of the golf course and more nectar for insects
Installation of nest boxes Birdboxes have been placed at different locations on the course for different types of birds, such as falcons, owls and humming birds. In total, we have installed 150 nextboxes.
In 2016 we placed 30 extra nestboxes. This is done in order to promote the population of Turdus merula.
Control / management of alien species During the winter, Prunus serotina has been removed to prevent it from spreading to fast. We also are planning removal of Pinus nigra and replace it for Quercus robur or Pinus sylvestris.
Provision of hibernation areas In the woodlands there have been placed several piles of wood and bundled branches. This allows mammals and amphibians to forage and hibernate.
Creation of micro-habitats (eg log and stone piles) Microhabitats have been created at various locations on the course, such as breeding ground, grooves of branches and woodpiles.

Water

Surface water from a pond located at hole 9 is used for the irrigation of the golf course. The level of the pond water is kept even by means of pumping-up groundwater. The water level, however, is often too low as a result of the demand for drinking water by the surrounding community and the demand to keep the water level artificially low due to local agricultural needs. The water level decreases dramatically during dry spells as a result of a porous soil structure and the absence of a hard, impenetrable layer of ground. The rusty colour of the water, resulting from the oxidation of iron when groundwater is pumped-up, is a matter of concern. Action is being taken to minimise water usage. There are two reasons for this: It optimises the rooting of the grass and it creates savings by only using the absolute necessary amount of water. Water usage is accounted for by the kitchen, toilet usage, shower facilities and in the cleaning of the accommodations, equipment and machines. On the golf course itself, water is used as drinking water. Since there is no separate water meter, we can not split the used amounts of water between the clubhuis and greenkeeper shed.

Voor de beregening van de golfbaan wordt oppervlaktewater vanuit de vijver van hole 9 gebruikt. Deze vijver wordt op niveau gehouden door middel van opgepompt grondwater. Door het intensief onttrekken van water in de omgeving van de golfbaan ten behoeve van drinkwater en het kunstmatig laag houden van het waterpeil voor akkerbouw, is het waterniveau vaak ongewenst laag. Door de poreuze bodemstructuur en het ontbreken van een harde, ondoorlatende laag dalen de waterstanden in droge periodes hard. Verder wordt de roestkleur in het water door oxiderend ijzer dat meekomt met het oppompen van het grondwater als storend ervaren. Er wordt sterk ingezet op het minimaliseren van de watergift. Reden hiervoor is zowel de overtuiging dat dit de beworteling van het gras optimaliseert, als de besparingsgedachte van waaruit alleen het noodzakelijke wordt ingezet. Het waterverbruik heeft betrekking op het gebruik van water ten behoeve van consumptie, gebruik in de keuken, toiletgebruik, douchen en het schoonhouden van de accommodatie, apparatuur en machines. In de baan wordt water gebruikt als drinkwater. Er is geen tussenmeter aanwezig om het verbruik van het clubhuis en de werkplaats verder onder te verdelen.

Activity Description
Selection of grass species An external specialist on golf course turf advises on the correct composition of grasses for the different parts of the course. The used grass species can withstand drought quite well
Soil decompaction and thatch management Yearly actions are taken to prevent soil compation through aerating and slitting and by working according to the managementplan.
Timing and dose of water application The modern irrigation system is computer-driven and arranges the water level. We choose the most optimal moment to irrigate
Analysis of soil moisture We keep an eye on the soil moisture. In a dry periods daily control of moisture.
We make use of a digital moisture meter. The percentage of moisture on greens is kept between 18 to 20 percent. On fairways it is a little higher. About 22 percent. This is because we have a lot of trouble with grubs. Because we keep the top layer more moister we need no pesticides.

Wij houden het vocht percentage goed in de gaten. In droge periodes vinden er dagelijks controles plaats. We maken gebruik van een digitale vocht meter. Het vocht percentage op de greens wordt tussen de 18 en 20 procent gehouden.
Incorporation of evapotranspiration rates and weather data A weather station is situated on the course which is closely watched.
Use of wetting agents Wetting agents are used various times during the summer months to minimise water usage and to prevent dryness.
Overall reduction in irrigated area We keep the irrigated area as small as possible by targeting the sprinklerheads.
Targeting of sprinkler heads The irrigation system is comprised of sector sprinklers. By yearly callibrating the system and targeting sprinkler heads, we have optimized the reach of the sprinklerheads
Optimizing system pressure The irrigation system contains an automatic pressure regulator that optimises the mains pressure.

Kwaliteit beregeningswater In 2014 we build a Helofyten filter to improve the quality of the irrigation water. This we made to de-ironing the ground water.

Energy

Golf Club de Koepel aims to minimise the use of energy and fuel through the use of automatic light sensory switches and energy-saving lighting. An expert-conducted survey in 2009 confirmed that the golf club was taking the necessary steps to enhance their energy-saving measures, although future savings can be made in limited ways.
Environment- and cost savings measures predetermine that supplies are kept to a minimum at Golf Club de Koepel. Pesticides are only used in a very limited manner due to their damaging effects. Green-keeping keeps a pesticide plan and in their daily decisions aims to attain the best results for the future. Over the past three years, the golf club has reached a stable use of energy, which is less than the three years before the first audit.

Golfclub de Koepel probeert binnen het redelijke het verbruik te minimaliseren van energie en brandstof. Door gebruikmaking van automatische lichtschakelaars en energiezuinige verlichting wordt hier gekeken naar een besparing. In 2009 heeft er een onderzoek plaatsgevonden. Door een deskundige is dit onderzoek uitgevoerd. Uit de rapportage blijkt dat de Koepel waar dat mogelijk is belangrijke energiebesparingsmaatregelen heeft getroffen. Mogelijkheden tot verdergaande besparing zijn nog wel in beperkte mate aanwezig. Gedurende de afgelopen 3 jaar heeft de golfclub een stabiel energieverbruik gehad dat lager ligt dan de drie jaar voor de eerste audit.

Energy Efficiency

This golf facility is undertaking the following activities to diversify energy and fuel supply:

Activity Description
Adoption of green tariff grid supply In 2016 golfclub de Koepel has found a new supplier for supplying energy. This supplier only delivers green energy.

In 2016 is Golfclub de Koepel over gestapt naar een nieuwe stroom leverancier. Deze leverancier levert uitsluitend groene stroom.
Use of biodiesel and /or ethanol yes, we purchase 'Aspen' as fuel for our smaller machines. This type of fuel is more environmentaly friendly
Use of electric hybrid vehicles We use electric golfcarts

This golf facility is undertaking the following activities to reduce energy consumption:

Activity Description
Investment in low-energy heating and air conditioning systems A high-yield heating system has been installed instead of an electric boiler.
Optimizing thermostat levels for heating and refrigeration Levels of heating and cooling are arranged centrally, but can also be regulated in separate areas in order to prevent unnecessary heating or cooling.
Enhancement of natural ventilation opportunities Optimising ventilation was a matter of concern in designing and constructing the clubhouse.
Installation of low-energy lighting Energy-saving lighting is attained through the use of as many energy-saving lamps and led-lamps as possible. Other old bulbs will be replaced by CFL during the next renovation.

In 2016 the whole greenkeepers building are posted LED lights.
Use of motion sensor lighting Movement sensors are used for the lighting in the locker rooms and in the toilets.
Transition to energy efficient appliances Energy labels are highly considered in the purchasing of new equipment.
Use of timers with appliances, heating and lighting Outdoor lighting is regulated via a timer that is often adjusted to sunrises and sunsets.
Educating staff and customers The staff is made aware of the effects of activities with regard to energy usage.

Ride-on Mowers Walking Mowers Utility Vehicles
Petrol 100% 100%
Diesel 100%

Additional vehicles operated by this golf facility use the following fuel sources:

Golf Carts Cars Buses
Grid Electric 100%

This golf facility has established the following schemes to encourage reductions in staff and customer transport emissions:

Activity Description
Secure cycle parking A cycle parking gives members the possibility to use a bike instead of car.
Increasing equipment storage (e.g. lockers) The locker room has been expanded to allow for the storage of not only the bags but also of the trolleys.
Staff showers Showers are available in the green-keepers shed.

Supply Chain

Environment- and cost savings measures predetermine that supplies are kept to a minimum at Golf Club de Koepel. Pesticides are only used in a very limited manner due to their damaging effects. Green-keeping keeps a pesticide plan and in their daily decisions aims to attain the best results for the future. Since the use of pesticides is low, we will only sum up the total amount of what is used, and not split the amounts further down to the separate parts of the golf course. In general, the greens are treated relatively the most with pesticdes, compared to the other parts of the golf course.

Milieu- en kostenbesparing zijn voor de Koepel genoeg redenen om leveranties tot het minimum te beperken. Gewasbeschermingsmiddelen zijn door de schadelijkheid voor de omgeving middelen die zeer beperkt worden ingezet. De greenkeeping hanteert hiervoor een gewasbeschermingsplan en maakt natuurlijk dagelijks de keuzes die voor de lange termijn het beste resultaat opleveren. Gezien de geringe hoeveelheid gewasbeschermingsmiddel dat jaarlijks wordt gebruikt, wordt alleen het totaal benoemd en het verbruik niet verder uitgesplitst. In de regel wordt op de greens verhoudingsgewijs de meeste gewasbescherming gebruikt.

Purchasing Policies

This golf facility undertakes the following ethical / environmental purchasing activities:

Activity Description
Measures to avoid waste at source We choose the purchased products on their environmental impact
Use of local suppliers Local suppliers are used for the purchasing of various products. Since the central location within Twente, all suppliers are located within 40 km
Use of local products Different regional products are offered on the restaurant menu whenever possible.

This golf facility undertakes the following actions to optimize pesticide use:

Activity Description
Selection on the least toxic and lest persistent products We only use products that are the least toxic to the environment
Selection of appropriate products for specific pests and diseases The correct substances are chosen as a result of the expertise present on diseases and plagues, and the use of pesticides.
Spot-treatment with handheld sprayers and wipers All diseases and plagues are treated locally, besides the greens and foregreens.
Calibration and testing of sprayers The ideal measurement is chosen depending on the substances used and the type of weather, thereby realising usage- and dispersion optimisation. Sprayers are callibrated on a regular base
Use of shrouded sprayer and anti-drip nozzles Spraying is done with anti-drip nozzles.
Non-chemical weed control In first instance, weeds are treated mechanically and biologically. Chemical treatment will only be considered in extreme situations.

Pollution Control

Green-keeping is sharply focussed on carrying out a responsible environmental management plan. This not only entails minimising the use of harmful substances, but also carrying out a responsible policy concerning, for instance, the use of pesticides. For example: If spraying against fungi occurs, this is done under the best climate circumstances and use is made of drifting-resistant spray nozzles (or, non-misting nozzles). The head of green-keeping is keenly focussed on the layout of the workshop and keeps unnecessary damage or wastage at a minimum through its orderly organisation. The drinking water will be controlled 2 times per year on quality. This is done by a laboratory on a chemical way.

De greenkeeping is sterk gericht op een verantwoord milieubeleid. Hierbij hoort niet alleen minimaal gebruik van belastende stoffen, maar ook verantwoord gebruik van bijvoorbeeld gewasbeschermingsmiddelen. bijvoorbeeld: Als er gespoten wordt tegen schimmels wordt dit gedaan met de juiste klimatologische omstandigheden en wordt er gebruik gemaakt van driftloze nozzles. Verder is de hoofdgreenkeeper allert op de inrichting van de werkplaats. Door ordelijk te werken is de kans op overbodige schade of verspilling minimaal. Het drinkwater wordt 2 keer per jaar op kwaliteit gecontroleerd. Dit gebeurt in een laboratorium en wel chemisch.

The ambition to manage the golf course in a responsible manner expresses itself in various ways. Communication among the members of the golf course commission and towards management is considered important. This communication forms the basis of the general meetings. Communication through the club newsletter addresses those issues and developments concerning nature and environment on the course. Golf Club de Koepel uses its website to timely inform its members of any measures taken concerning the course. This timeliness further enhances member understanding for the need to take policy-driven measures. Separate reserves for nature projects are created in the yearly budget further giving root to the club’s nature and environmental care policies.
