On 16 July I carried out a re-audit of the Rijswijkse Golfclub. The audit consisted of examining documents which were made available, a meeting with those responsible for GEO and an inspection of the premises. In order to embed the sustainable use of the golf course, the Rijswijkse Golfclub has, in the last three years, made progress in each of the six areas identified by the GEO organisation. In general, the GEO committee made a good impression on me. The Rijswijkse Golfclub has put a lot of effort with considerable enthusiasm into sustainabil…

The course of the Rijswijkse Golf Club was constructed in 1988 in the south-eastern part of the Municipality of Rijswijk. In the Middle Ages, a knight’s homestead, Craayennest, was situated here and around 1736 the estate ‘Craayenburgh. The golf course consists largely of water, grasslands and planted areas. The connection with a large recreational area and ecological zone offers a substantial potential for various sorts of animals. The soil, which primarily consists of clay, has less potential for very rare plants, but can house a large variety of sorts.
The location of the Rijswijkse Golfclub is special and of great natural value. The enormous urban pressure on the environment means that the golf course, together with nearby parks, becomes a green buffer zone that can guarantee natural quality.
The golf course has reed beds, plant areas on a bank with a well-developed shrub layer and a number of small pools. Various stock takes have been carried out on the course to chart the flora and fauna. Special sightings include the caterpillar of the Chamomile Shark Moth, the Eurasian Woodcock, the Kingfisher, the Cuckoo and the Southern Marsh Orchid.

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

  • IPC Groene Ruimte
  • Lawn Care - Jan van Monfrans

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 The head greenkeeper monitors daily whether additional irrigation or fertilisation is required. He is also responsible for the cutting heights and mowing frequency.

Conservation & Enhancement

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

Activity Description
Appropriately matching mowing lines to contours The grass cutting lines run parallel to the shape of the holes which allows for visibility of raised areas in the terrain.
Protection and restoration of historic features The concrete bunker is maintained to make it accessible for bats.
Discreet on-course signage and furniture Signs, benches, shelters are maintained. The hole signs have been placed in such a way that they are not in the line of sight.
Conservation of specimen trees Ornamental and notable trees are conserved and, where necessary, planted around the clubhouse.
Screening and softening unsightly man-made features The greenkeepers hut is located behind a bank covered with trees and shrubs. Fences designated to catch golf balls have a black or green colour and have been constructed, where possible, out of sight.

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 The area of mowed grass is kept at a minimum. Because of the nutriënt rich soil, it is not always possible to mow more extensive.
Increasing the size of habitat patches Locations where the rough can be extended are being identified and more natural banks are being created.
Connection of internal habitat patches The whole terrain is surrounded by a border of plants and shrubs. A large area of the rough borders a natural bank and/or planted area.
Connection of patches with external habitats Despite the urban location, the golf course is, through a line of trees along the Delftweg and the canal connected to the environment. To the south west there are two parks which are reasonably accessible to various groups of animals.
Avoidance of habitat fragmentation The shrubs around the course are maintained, also as protection from the motorway.

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 More locations to create rough and extensively controlled grass land are being sought. The past years, we had sheeps grazing in the roughs. This resulted in a more diversified vegetation.
Ecologically informed management of scrub vegetation struikvormers krijgen voorrang bij het beheer van de geluidswal. Shrubbery is given priority in the maintenance of the dividing bank/sound barrier.
Promoting species and structurally diverse woodlands In a part of the planted areas there is some variation, in the degree of density as in the transition from playing elements to plant elements.
The major part of the tree varieties is indigenous by thining the woodlands selective and planting species indigenous to the area. This also provides for a spreading of different age groups.
Establishment of littoral shelves and marginal vegetation in wetland areas vijver hole 7 heeft glooiende oevers gekregen, vijvers bij hole 14 en 18 zijn voorzien van natuurlijke oevers. The pond of hole 7 now has sloping banks, the ponds of holes 14 and 18 now have natural banks.
Maintenance of an appropriate balance of open water and aquatic vegetation Nearly half of the banks of the water areas consists of natural banks. These banks are extensively managed.
Increasing sort diversity The possibilities to improve the diversity of tree sorts are being investigated. In the long term, the current planted areas will be changed for a large part by introducing different varieties of indigenous deciduous trees.

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 The presence of herbaceous vegetation, in particular in the surrounding plant areas is an important feeding source for insects.
Control / management of alien species Bij beheer aan de plantvakken krijgen inheemse boom en struiksoorten voorrang. In management of planted areas, indigenous trees and shrubs are given priority.
Provision of hibernation areas The concrete bunker is suitable for bats as a hibernation/resting place. Moisture levels of the bunker will be regulated to make it a more suitable place for bats to stay.


In the clubhouse, tap water is used for the catering, changing rooms with showers, toilets and other water points. During the building of the new clubhouse of the Rijswijkse Golf Club, equipment to reduce water consumption was installed as much as possible.
A computer-controlled system is used for irrigation, as well as application in a location-oriented manner. Surface water is used for irrigation of the golf course. The necessary licenses have been obtained. The sprinklers have partly been substituted by sector sprinklers, in order to be able to better control the irrigation. The water storages are controlled by an irrigation computer. This system was recently replaced. The amount of water is determined by the measuring of the precipitation and from the experience of the head greenkeeper. The elements which are irrigated are: greens, foregreens and tees. If necessary, fairways may be irrigated manually by the use of reels.
Wetting agents are used in the summer months to reduce the application of water. In the short term, the cost of installing a meter to measure the use of irrigation water is being investigated.
