Restoration of a monumental diorama by Rowland Ward containing a sample of the Australian fauna, dated circa 1892. An attack by parasites and poor conservation conditions led to severe degradation of the animals. A multitude of techniques were implemented to restore this diorama to its original condition. Rowland Ward's history completes the narrative.

The techniques developed to stabilize falling out furs and plumages have been published in the Journal of Natural Science Collections : Castelain L. 2024. Conservation of extensively falling out hairs and feathers in a Rowland Ward’s 19th century diorama. JoNCS, 12 : 126-135.
