The so called ‘Oude Dame’ (the “Old Lady”) was founded in 1893 and is the oldest golf club in the Netherlands. It started with a golf course in Waalsdorp, near The Hague. In 1938, a golf course was constructed behind villa De Wildhoeve in the village of Wassenaar, which was acquired by the club in 1947. The course as designed by the architectural firm of Colt, Alison & Morrison Ltd. The new constructions maintained the waving rhythm of the course plots, allowing the golf course to naturally transition into the surrounding dune landscape. Th…

The present golf course of the Royal Hague Golf & Country Club was built in 1938. It is a links-course located in the dunes of Wassenaar, near The Hague, and is known in Europe as a ‘Championship Course’. This unique course is located in a valuable dune area approximately three to four kilometres from the North Sea. The course is part of the Meijendel dune area. The “Haagsche” has made it their responsibility to not only conserve or restore the nature found on its terrain, but also to improve and optimise it without making concessions to the game of golf.
The Meijendel dune area consists mainly of parabolic dunes with various slacks. The high, steep inner wall of the dunes borders the landside of the golf course. The dune area has an open character marked by local forest, thicket, and dune grasslands.
Approximately half of the total surface area owned by the club constitutes the golf terrain. Located between the various holes are valuable open dune grasslands, high and low thicket, and woodland.

De huidige golfbaan van de Koninklijke Haagsche Golf & Country Club (KHG&CC) werd gebouwd in 1938 en staat in Europa bekend als een "Championship Course" van uitzonderlijke klasse. Het terrein ligt in een prachtig waardevol duingebied op ongeveer drie tot vier kilometer van de zee. Landschappelijk gezien maakt het deel uit van het duingebied "Meijendel”. De KHG&CC ziet het als haar plicht de natuur op haar terrein niet alleen in stand te houden en waar mogelijk te herstellen, maar ook gericht te verbeteren en te optimaliseren zonder dat afbreuk wordt gedaan aan de golfsport.

Het duingebied Meijendel bestaat voornamelijk uit hoog paraboolduin met verschillende uitblazingcomplexen en wordt aan de landzijde begrensd door de hoge steile binnenduinrand.
Het gebied heeft een open karakter met lokaal bos, struweel en duingraslanden.
Ongeveer de helft van de oppervlakte van het terrein van de “Haagsche” is golfterrein. Tussen de verschillende holes liggen potentieel waardevolle open duingraslanden, laag en hoog struweel en bos.

The terrain of The Royal Haagsche Golf & Country Club is located in the water-collection area of the Dune Water Company South Holland (DUNEA). It is situated between the deep and the shallow collection areas of the Kijfhoek and Bierlap, and the deep collection area of ‘de Kaswetering.’ There are no infiltration pools in the direct vicinity of the golf course. The water collection from the shallow groundwater area has only a small impact on the terrain. Hydrologic monitoring by the DUNEA shows that groundwater in the shallow parts is located at approximately 2.5 metres below NAP. For this reason, there are no actual or potential moist dune valleys on the terrain. In 1938, the course was built with an underground network of water pipes meant for irrigation. Around 1970, the ‘Haagsche’ was the first Dutch golf club to install an automatic irrigation system. From 2004 the system was replaced in stages by a fully modernised system, which allows for selective irrigation, thereby, enabling separate parts of the course to be watered and to be monitored. The last stage (fairways) was finished in 2012.
Evaporation is minimised by irrigating mostly during the evenings and nights. Irrigation is normally limited to the greens and tees, and never more than necessary for the desired quality of turf. In extreme dry conditions irrigation of fairways might be necessary. Limited irrigation, in general, leads to improved quality of the sward. Sector sprinklers are used as much as possible in order to prevent irrigation of the rough and the dune landscape.
This leads to increased water efficiency and meets the policy of the club in minimising water usage.

Het terrein van de KHG&CC ligt in het waterwingebied van het Duinwaterbedrijf DUNEA tussen de diepe en ondiepe winningen van de Kijfhoek en Bierlap en de diepe winning "de Kaswetering". In de directe omgeving van de golfbaan zijn geen infiltratieplassen. De waterwinning in het ondiepe grondwaterpakket heeft slechts een zeer beperkte invloed op het terrein. Uit de hydrologische monitoring van DUNEA blijkt dat het grondwater in het ondiepe deel gemiddeld op 2,5 meter onder NAP ligt. Om die reden zijn er geen actuele of potentiële vochtige duinvalleien in het terrein. Reeds bij aanleg in 1938 van de Golfclub de Wildhoeve werd een ondergronds leidingnet aangelegd zodat de baan kon worden besproeid. Dit was uniek in Nederland. Rond 1970 legde de "Haagsche" als eerste golfclub in Nederland een automatische beregeningsinstallatie aan, die vanaf 2004 in fasen werd vervangen door een geheel nieuw automatisch systeem. De laatste fase werd in 2012 voltooid. De hoeveelheid opgepompt water wordt voor beide pompen afzonderlijk geregistreerd.
Het beleid van de club is gericht op minimaal gebruik van water.
Er wordt hoofdzakelijk in de avond en 's nachts beregend, voornamelijk op greens en tees en nooit meer dan noodzakelijk voor de gewenste kwaliteit van de grasmat. Bij grote droogte worden ook de fairways beregend. Beperkte beregening leidt in het algemeen tot een betere kwaliteit van de grasmat. Er wordt zoveel mogelijk gebruik gemaakt van sectorsproeiers zodat zo min mogelijk water in de rough of het aangrenzende duinlandschap terecht komt.

Supply Chain

Purchasing of new products focuses on environment-friendly products, especially for the machinery. Will certain machines be replaced by less polluting and more silent ones, driven by electric motors? An earlier bought hybrid machine turned out not to be successful and was exchanged after a year.
However, replacement of machines by hybrids or machines fully driven by electric motors will certainly be considered in the future. They are more economical and less sensitive to leakage and breakdowns.

Bij de keuze van nieuwe aankopen wordt tegenwoordig, met name voor machines, gezocht naar milieuvriendelijke oplossingen. Kunnen bepaalde machines inderdaad worden vervangen door minder vervuilende en stillere, elektrische machines? Een eerdere aanschaf van een hybride machine bleek nog geen succes en de machine werd snel weer ingeruild. Vervanging door hybride of geheel elektrisch aangedreven machines wordt in de toekomst wel degelijk overwogen. Zij zijn zuiniger en bovendien minder gevoelig voor lekkage.
