Standard orchards are no longer common. They can still be admired on the Bredius Estate. There are two large orchards and several smaller ones with old apple varieties, such as the Goudrenet and the Notarisapple, and old pear varieties, such as the Saint-Rémy and the Legipont. The oldest fruit trees are over 100 years old. Originally, there were over four hundred fruit trees on the estate, spread across sixteen orchards. The estate now has 370 fruit trees.

Raised benches have been installed in some places in the Groene Jonker to enjoy a good view. I can imagine that it is busy here in the spring with many bird watchers who would like a high bench.
