Giant German Oaks

Our German speaking members will be interested to learn that a new book on giant oaks in Germany was published in September 2017: Riesige Eichen — Baumpersönlichkeiten und ihre Geschichten (Giant Oaks — Tree Personalities and Their Stories). The work of Dutch tree photographer Jeroen Pater, the book includes detailed portraits of 150 of the most impressive oaks in Germany, some of which have not yet been listed in catalogs. Beautiful photographs capture the majesty and dignity of these silent witnesses of the past, while historical illustrations of selected trees allow interesting comparisons. This magnificent picture book featuring Germany’s largest tree personalities includes a map showing the location of each tree.
