[PCA] Question about Gymnocladus dioicus

[Snyder, Eric (MNRF)]

Hi,

I have two questions for anyone who has experience either monitoring or cultivating Kentucky Coffee-Tree (Gymnocladus dioicus):


1.       At approximately what age, or within what age range, do trees become sexually mature?

2.       How far from competing vegetation must a tree be planted in order for it to be considered "free to grow," i.e. free from competition?

Gymnocladus dioicus is listed as threatened in Ontario, Canada.  The answers provided to the above questions will be used to inform "overall benefit" conditions in an authorization under Ontario's Endangered Species Act.

Thank you for any insights you can offer.  Kind regards ...

Eric

 "If it had been expended solely upon the plants which are grown to please the eye, or which invite us by their nutrimental properties, this laborious research on the part of the ancients would not have been so surprising; but in addition to this, we find them climbing by devious tracts to the very summit of mountains, penetrating to the very heart of wilds and deserts, and searching into every vein and fibre of the earth-and all this, to discover the hidden virtues of every root, the properties of the leaf of every plant, and the various purposes to which they might be applied." - Gaius Plinius Secundus, c. 77A.D.
