The Wych Elm of Park Middenburg

One of the oldest wych elms in the Netherlands stands on a lawn behind an office building. The office was a manor house first: Middenburg was a country estate by 1657, and the grass the elm stands on was somebody's private view until Voorburg council bought the place in 1952 and opened it as a park. A Dutch tree register puts the planting at 1750. That is a round number with no stated basis, so read it as a band rather than a birthday: somewhere between 250 and 300 years, which still makes this one of the oldest of its species in the country. It has spent the last century in a difficult neighbourhood for an elm. Dutch elm disease was first identified here in the 1920s and went on to take most of the country's elms with it. This one kept going, and was measured at just over 20 metres in the summer of 2017. One open question, which we would rather ask than quietly answer. Some records suggest this is the Exeter Elm, a narrow upright cultivar, rather than the wild wych elm its Dutch name implies. If you know which it is, or have simply stood under it lately and can report it is still in leaf, tell us.
