Locations of Japanese Knotweed in Son en Breugel

Here is a list of the locations in Son en Breugel where Japanese knotweed (JDK) has been found, as far as we know.

Known JDK locations in Son en Breugel; roughly from south to north

  1. Groensteeg: 4 locations. Viewed from west to east: on the left near the (switch?) box with posts and past the entrance to the shed in the shoulder/ditch; further on, near the paved area (on the left), on the right side; and a little further on, where the small building stands in the field: also on the right in the shoulder and ditch. The municipality cleared these locations in September 2025, but the JDK had already regrown significantly by October; volunteers removed1 m³ of roots on October 25 and another 9 full green trash bags in early November 2025. The southern locations are maintained by local residents, while the northern ones are tended to by our volunteers.
  2. Triangle, between the intersection with Groensteeg and the Water Board's marker post:
  3. Hooijdonk: seen from the canal bridge towards Nederwetten, on the left after the large barn and thus opposite the entrances of house numbers 1 and 1a: in the verge to the edge of the road, in the ditch far (estimated 10 meters) into the woods.
  4. Extended Huizingalaan, left of the bike path leading to the Wilhelmina Canal.
  5. Wilhelminakanaal, west of 't Haventje 2 locations; on the other side of this, the north side: 2 locations and on the south side near the Hooijdonksebrug. These are the responsibility of Rijkswaterstaat, which is aware of them but does nothing about them.
  6. Corner of Mill Street/Wilhelminakanaal: one of the first sites to be covered by volunteers since August 2021. Meanwhile JDK-free.
  7. Around and behind the electricity house in the turn of Molenstraat and garden of van Rooij on east side: one of the first locations volunteers have been working on since August 2021. Meanwhile JDK-free.
  8. Crocus Street 3, in the backyard with offshoots to Crocus Street 5; resident of No. 5 installed a screen deep into the ground and a volunteer has been poking off what sticks outside the fence for several years.
  9. Crocus Street 14 and 16: in the backyards to the Groote Beek; will be removed by residents as much as possible. 
  10. Beek Street, on the shoulder and bank of the Groote Beek across from house numbers 4-16. Since August 2024, volunteers have been trying to eradicate the JDK there.
  11. Beekstraat, on the opposite side of the Groote Beek—that is, the terrace of the former ’t Krut. Volunteers have been working on the riverbank since April 2025.
  12. Zonhove, next to bridge over the Groote Beek on Nieuwstraat, one of the sites volunteers have been taking care of since April 2023. By also removing as much of the roots as possible, this location was JDK-free after just over a year and a half.
  13. Zonhove forest, next to northern path of Gnome Path, off house number 5 in De Bontstraat as well as in the hedge of house number 5: one of the locations that volunteers have been taking care of since August 2022. Meanwhile JDK-free.
  14. Outlying area: 650 meters west of the Stad van Gerwen bridge, in depth along the canal and 50 meters further along path towards Stoerderij in Breugel. Being addressed by volunteers since September 2024.
  15. Larch Avenue 1: in the garden and next to and in the ditch that runs next to the garden. Has been regularly addressed by volunteers since 2024. Ditch is now virtually JDK-free.
  16. Argus butterfly avenue, at the end, between house numbers 9 and 10: a field that extends deeper into the forest. Since April 2024, a second club of volunteers has been working here with fine results.
  17. Spanvlinderlaan 9/10: near/in the ditch that will be dredged in 2026; residents of this street are trying to eliminate the JDK here.
  18. Keizermantellaan: in the park across from house number 27. Is being tackled by a resident on that street; it is now most likely free of JDK.
  19. Larch avenue: north of house number 7, around the thick tree, along the road and also a bit into the forest path as well as behind the garden of no.7; one of the locations that volunteers have been working on since September 2021. The JDK has virtually disappeared there by now. Deeper into the forest a single specimen of JDK is still sometimes found.
  20. Plesman Avenue: at the bend, near the bike path. Large slice as well as among the bushes around it: one of the first locations that volunteers have taken care of since August 2021. Less and less JDK keeps coming up.
  21. Butterfly Avenue, from the traffic circle on the right. Volunteers have been removing the narrow strip of JDK since June 2024; getting fewer and fewer.
  22. Between Potjesberg 5 and Hoogenberg 2 along pathway; Few were involved, addressed by volunteers since 2022. Now JDK-free.
  23. Olen, in roadside/ ditch diagonally across from farm with house number 42. Removed by volunteers since mid-September 2024.
  24. Dommelpas: 2 locations: north side, among the trees, across from the deer enclosure, and west side, at the front, next to the garden at Koekoeklaan 2. Since September 2024, volunteers have been working on the front location, and it is now almost free of JDK. In June 2026, an experiment with Jerusalem artichokes was launched in the enormous field, which may help (partially) control the JDK.
  25. Dommelpas Breugel Field: In the woods near the Dommel River, there is a very large stand of Sakhalin knotweed. It was discovered in the summer of 2025. In July 2026, all the large stems were cut down to prevent the plants from flowering, because it had been found that the pollen can fertilize the flowers of Japanese knotweed. 
  26. Hoogstraat Breugel: along the path to the backyard of house number 1. This is a very small area; it is being treated by a volunteer and is now free of JDK.
  27. Forest between Bremlaan, Hoplaan, Nachtegaallaan and Hendrik Veenemanstraat: Behind the garden of no.6, accessible via the path next to no.4a. To be tackled by volunteers from May 2025.
  28. Poppy Avenue 9, in the front yard. Resident and volunteer fired it regularly. Probably JDK-free by now.
  29. Poppy Avenue 6 (and also 4): in the backyard. Owners fight JDK themselves (after being explained). By now virtually JDK-free.
  30. Kwadestraat, seen from the Lieshoutseweg at the first right-angle bend: on the left, a tall upright field full of JDK estimated at 10 by 20 meters! To the right in the bend, in the ditch, there is also a (still very small) field.
  31. Lieshoutseweg: by the tree east of house number 4 (i.e. opposite house number 3).
  32. Orion Avenue, in the (dry) ditch behind the sheds of house numbers 18-22. Residents remove shoots regularly. By now virtually JDK-free.
  33. Orion Avenue 37, in and behind the garden in the municipal park, residents try to keep the JDK out of their garden, but in the municipal park there is still JDK.
  34. Archer Avenue: left at end of bike path through park towards Orion Avenue. Kept by volunteer from Zuiderkruislaan.
  35. Uranuslaan 5 and 7: in the gardens of private residences. Explanation provided on August 3, 2026.
  36. Van Anrooijlaan/Dresdenlaan: in the forest edge some specimens, removed by volunteers each time since 2022. By now JDK-free.
  37. Gentiaanlaan, next to the entrance to the municipal yard/fire station and on the yard grounds.
  38. Planetenlaan/Vresselseweg, at the corner near the community gardens. The city cleared the area in September 2025, but the Sakhalin knotweed is growing back there.
  39. Rooijseweg, north of the entrance to the municipal yard and on the grounds themselves.
  40. Wolfswinkel, at the bend northeast of house number 4: in 2022, it was a huge patch. The city addressed the issue, and in consultation with local residents, sheep are now grazing there to eat the JDK.
  41. Vlielandlaan, across from Amelandlaan: treated by volunteers starting in late April 2024; now free of JDK.
  42. Weser Avenue next to house number 22. Has been addressed by volunteers since April 2025 and is moving in the right direction.
  43. Honey bee 4: behind the shed, at/in the forest edge several specimens. Storage of JDK was removed by resident and a volunteer. Probably JDK-free by now.
  44. Bee Avenue 2: in back of garden. Will be maintained (after explanation) by owner.
  45. Dommel, right bank near Hertenkamp; left bank near border with Nijnsel; falls under the responsibility of Waterschap de Dommel, which does nothing about it.
