However, due to the way that the toxin alters and destroys red blood cells, longer term but lower magnitude exposure may lead to clinical disease. So it is best to take steps reduce the risk of any exposure to the leaves.

As a horse owner, I didn't know this about Red Maples and I appreciate your info so much. If my calculations are correct - it means that eating 2 pounds of wilted or dead red maple leaves could kill my 1,000 pound horse. I'm guessing that she'd need to eat that within a short time period, days rather than over several weeks or months- is that correct? Or do the toxins accumulate? Either way, I'm going to check around my property and see if I can identify this particular tree here in the NW Arkansas Ozarks. Some of our trees are turning red right now in late October though most seem to turn yellow or orange. Thank you again!Unknownhttps://www.blogger.com/profile/14410459547024725849noreply@blogger.com
