Sallandsche Golf Club
Executive summary (English & local language)
Sallandsche Golf Club De Hoek is a golf club and course in Diepenveen, a small village part of the municipality of Deventer. The landscape in this region is formed by the river IJssel. Setllements arose in the middle ages on the higher grounds alongside the river. These settlements grew into cities, such as Deventer. The small village of Diepenveen was founded around a monestry near Deventer. The rural village grew in the 19th and 20th century with the realisation of roads and railroads and the appearance of industry. Around Diepenveen exclusive houses were built and estates were founded by rich inhabitants of Deventer.
The golf course is situated on the east side of Diepenveen. On the northeastern side the course is adjacent to meadows from dairyfarms. On the southern side there are woodlands owned by the organisation IJssellandschap, a local nature organisation.
The course is managed by De Enk, a landscaping company that manages over 20 golf courses in the Netherlands. The interview and course visit took place with two members of the GEO committee and the head greenkeeper from De Enk.
The golf course is situated on sandy soils with loam. These soils are part of a larger complex of sandy soils in the eastern part of the Netherlands. The soil is relatively dry and there is not much open water on the course.
The course is divided into two parts. The older part is a 9 hole course established in 1933 and here there are mixed woodlands with indigenous species and conifer species. Parts of these woodlands are part of the national network of nature reservers (Natuur Netwerk Nederland). There are small patches of heather in the older part of the course. The club is trying to improve and expand these patches. For 2019 the club has reserved money for the cooperation with a local sheppard. The sheep will eat the grass and young trees in favour of the heather plants.
In 1987 the course was expanded with 9 extra holes. This new part is more open with grasslands, solitary trees and a larger pond with natural shores. The roughs are botanically rich and the club is trying to increase the variation in species in these roughs.
The nature values on the course are high. Ecological surveys from the period 2013 - 2017 show a large variety in birds, plants, amphibians and mammals. The presence of the orchid Epipactis helleborine (Broad-leaved Helleborine) deserves a special mentioning. This plant was protected in the Nederlands until 2017. The survey for mammals will be expanded and a local volunteer from a youth nature organisation will conduct a survey for dragonflies and butterflies. All together these surveys will give a good overview of the ecological values.
The club is working on a turf grass mixture that matches the soil better. The amount of Poa annua on the greens is being reduced in favour of Agrostis species.
The course is realised on the grounds of an old estate. There are still elements present of this old estate, such as tree lanes, a hill with a tea house and an big, old solitary oak. In the recent years lanes have been restored. The old oak is depicted on the emblem of the club
For the irrigation of the course ground water is being used. Greens are kept green, but fairways are allowed to colour in dry periods. Groundwater is also used for the washing of the machines. There is no surface water available for this. In order to use less ground water and improve the strength of the grasses on the greens the club wants to decrease the use of water for irrigation.
The use of drinking water in the clubhouse has declined a little bit in the recent years. The club house has been renovated in 2013 and there are several water saving measures, such as stop flush toilets and low use shower heads.
A water audit has not been conducted yet, but the club wonders if a water audit will lead to new insights an measures for water saving.
The club has a green tariff for electricity since 2016. With the renovation of the clubhouse the building is also insulated. There is an energy report from 2013 with possible measures to save on energy in and around the clubhouse. Most of these suggested measures have been executed, but it is not clear what the exact status of all these measures is. An evaluation of the old energy report together with a new energy audit might lead to further measures to save on energy.
The club has looked into the possibilities of solar panels, but the purchase of panels appeared to be economically not interesting yet. This research is from a couple of years ago and it is worthwhile to do a research on this again. This can be part of a new energy audit.
De Enk is already using two hybrid mowers on the course and in the future they will use more hybrid or electric machines. This company has the goal to replace all its machinery by electric versions as part of their Corporate Social Responsibility policy (CSR).
The restaurant is run by an independent entrepreneur. There are no criteria for the purchase of sustainable products for the restaurant and the club has not yet discussed this with the entrepreneur. There could be an opportunity here to collaborate for the benefit of both the club and restaurant, including more sustainable supply chains and a multiplier effect within the local community.
For the fertilisation mostly inorganic fertilisers are used. On the greens some organic fertilisers are used and the head greenkeeper is willing to experiment more with organic fertilisers. The year of 2017 shows a clear decline in the use of chemicals compared to the years before. According to the head greenkeeper in 2018 only some organic pesticides have been used so far. Because of the dry summer he expects to use some fungicides later in the year. The goal of the head greenkeeper is to use as little chemicals as possible and to be ready for the new legislation in 2020.
All waste material is being re-used or is collected for recycling. In order to reduce costs and the use of fuels, the club will ask for a special winter arrangement for the collection of certain types of wast. Untill recently pruning wood was being was being shredded and the wood chips were spread out in the woodlands. But this lead to a high use of fuel and to vegetation encroachment in the woodlands. The club will no lay the branches in special rows of branches. This will also improve wildlife.
The club has filled in the NGF environmental checklist, which includes hazardous materials infrastructure and handling, among many other things, and no actions were required. The greenkeepers facility on the course is a modern complex. De Enk is responsible for the storage of hazardous materials, the maintenance of machines and the washing of the machines. This company is certified for the construction and management of golf courses.
Rainwater from the roof flows into the sewer system. The club will explore the possibilities to use rainwater from the roof for irrigation of the course.
The golf club cooperates with several volunteers and organisations. Members with the necessary expertise are voluntarily conducting ecological surveys in cooperation with local volunteers from outside the golf club. For advice on forest management the club consults the local department of the Bosgroepen (an association of forest owners). And the club is in good contact with neigbours from IJssellandschap, the organisation that owns the estate next to the golf course.
There is country lane that crosses the golf course on the borders of the old and the new part of the course. This road is used by the people from Diepenveen for walking, running, etc.
The club organises open days once a year and golf clinics for schools. Members are informed about sustainability and GEO through newsletters and the website. The information about these issues on the website is scarce, which could be an area of improvement. There is a list with short term and long term actions to perform in the coming years by the GEO committee. The current members of the committee will have to make sure that their successors will continue with the performance of these actions.
The course of Sallandsche golf club De Hoek has a great diversity in landscape and nature because of its history. The club is actively working to further strengthen the local biodiversity. Together with the landscaping company De Enk the club strives to reduce the use of chemicals and reduce the use of water and energy. The club is also active in involving local volunteers in the management of the course. I recommend that Sallandsche golf club De Hoek can be awarded for their GEO certificate.
Diversity in landscape and natural habitats between the two parts of the course.
Decline in use of chemicals and so far no chemicals used in 2018.
