OPM & Ash Dieback in the Dutch Urban Jungle

Eindhoven – Wednesday July 8th and Thursday July 9th, 2020

Holland Safari Bus

The Association is arranging a two-day study tour in the Netherlands. The goal is to facilitate the opportunity to experience first-hand the consequences of oak processionary moth (OPM) presence in the eastern Netherlands and to witness the results of ash dieback (ADB) in the West.

Excursions will be shaped using field trips taking participants to infestation ‘hot spots’, providing numerous examples. The aim is to provide practical information, show the effects on the trees, but also to include management and policy insight regarding these major diseases.

Thursday July 9th

  • Pick-up at hotel in the morning with Safari Bus
  • Introduction and transport to ash dieback area in the western part of the Netherlands
  • See the effects of ash dieback in urban area
  • Management of ash dieback at Amelisweerd Estate, Utrecht

The excursion will be led and prepared by Henry Kuppen. He is CEO of Terra Nostra and has a practical background consisting of 36 years of experience in Arboriculture and is one of the key composers of the Ash Dieback National Survey Standard in the Netherlands. Henry is also board member of the National Oak Processionary Moth National Knowledge Centre and is considered to be a leading expert on OPM. Henry has been involved with OPM management in the UK as of 2009. Mrs. Wendy Batenburg, Arboricultural consultant and scientist will provide an insight in relevant OPM management issues. Her main area of expertise includes in-depth analysis of OPM data such as pheromone trap results which can be considered the foundations of effective and realistic disease management and policy. Mr. Roel Geerts, Arboricultural consultant, has been leading ADB surveys in the field of ADB as of 2014; working with data analysis to identify disease development through the years, identifying specific outcomes in the numerous ash species and varieties that are used in the Netherlands. These outcomes are used to aid and direct ADB management decisions.

The cost for the 2-day tour will be £275 per person – this will include all land transportation, all host and speaker fees as well as coffee/tea, soft drinks and lunch on both days.

Note – Attendees will be required to make and pay for their own travel and hotel arrangements (The Association will provide details of recommended local hotels and rates to all delegates).

Numbers will be strictly limited to a maximum of 35 participants – and the Association will reserve places on a first come first served basis.
