hi guys,

This is my first question, any input will be greatly appreciated.

I have the perfect place to plant three large canopy type trees or
shrubs in our giraffe exhibit. The trees will have time to grow to 10
feet before the animals can reach them. At maturity they will cast
shade in the front of the exhibit for the animals. The keepers say I am
crazy, that the giraffe will mow them down. I say it is worth a try to
give the animals shade and forage. Any suggestions, also any
suggestions about plant material. I am zone 9b with lots of rain.
Black loqust, Robinia pseudoacacia would be exacly the shape and
foliage type but I think I have seen it on a few toxicity list. Any
suggestion? ALL INPUT WELCOME, and if this is a bad idea like the
keepers say, don't hold back.

Thank you in advance,
nancy
