A funny story
My first Arab bumped into the tree, some nuts fell off, he took them, spit out the green soft shell and ate the walnuts.

I guess it depends on what else your horse has to eat.

My horses have been exposed to Walnut trees their entire lives - two of them are in their mid-20's, the other two in their late teens. They were on very large acreage, so lots of forage to choose from.

If your horse is on tiny acreage or drylotted and there happens to be any sort of tree in the lot, then I would worry. I would worry about the tree, as well, because horses WILL eat bark out of boredom

The danger from walnuts isnt from eating. The danger is from the toxins getting into their feet. Yeh sounds funny but that is what it is, the roots also give off a toxin, sorta an "Keep away" natural weed killer around the tree. But blue grasses and probably some others are immune to the toxin. The danger from black walnuts is usually only if you are making wood chips or sawdust shavings from them. A live tree standing there, wont do much.

Have to clarify....my walnut tree wasn't the infamous black walnut.
Questionable trees need fenced out.
I also found trees in pasture are rarely a problem as long as there is good grass. Trees in drylots have a very short life expectancy.

Great!!!! My horse is like a girraff on crack when she is not being watched, and sometimes when she is being watched. I just got rid of the weeds. Now I have to trim the darn trees? I have no idea what kind of trees they are, but guess that's my next project.

Sorry didn't mean to rant on your thread.

The following trees have no place in horsekeeping areas because of their toxicity or potential for causing digestive distress. They are listed in order of the risk they pose to horses, starting with the most hazardous:
Yew (taxus sp.)
Oleander (nerium oleander)
Red Maple (Acer rubrum)
Cherry trees and relatives (prunus sp.)
Red Maple (Acer rubrum)
Cherry trees and relatives (prunus sp.)
Black Walnut (juglans nigra)
Black Locust (robinia pseudoacacia)
Horse Chestnut, Buckeyes (aesculus hippocastanum)
Oak trees, acorns(quercus sp.)
Russian olive, also known as oleaster (elaegnus angustifolia)
For more information on toxic trees, including detailed descriptions and photographs, visit the Colorado State University website

I'll add that you need to read up on the details, e.g. There are many kinds of oak trees and our mares have never had a problem munching on some acorns at our place in the fall every year.

I think what I may have is white walnuts, but how do I be absolutely sure? Is it just the concern of the horse eating the black walnuts that fall on the ground? And colicing?

The majority of the trees are a foot or two away from the fence line, but I so have two very small trees just babies that are in my pasture and I would like to be sure before I take them down
