Posted Sign with Poison Ivy

Why is it SO common to see poison ivy growing on the No Trespassing signs along country roads? Because roadsides are perfect poison ivy habitat. Poison ivy grows in the deep woods, but it prefers places with more light; roadsides have tons of light.

log and thick poison ivy vine

This large tree fell across a trail and was chain sawed off by a helpful person.

But I wonder if they knew that the thick vine attached was poison ivy?

A chain saw will spew sap and wet sawdust right at the logger and could cause a great deal of grief for both logger and family!

Here is an interesting story sent in by a viewer. We are looking for input from veterinarians or from anybody who has anything to offer about the possible affect of poison ivy smoke on animals. It is widely reported by all the books on poison ivy that it doesn't affect animals, only people.

If you make your living by climbing on others, when they fall, you go down to.

These poison ivy vines were happily climbing this little tree, but when it fell it took them down too.

winter poison ivy shrub

Here is a small poison ivy shrub that is mostly covered by snow.

In a situation like this, it is VERY hard to spot that this poison ivy during the winter. Poison ivy shrubs don't have the reddish hairy roots that the climbing vine has. So there is nothing that screams out POISON IVY.

poison ivy vine climbing dilemma

Here is an unusual situation: a poison ivy vine was climbing up a tree, a totally normal thing.

But when the tree split into two trunks, the vine found itself right between the two, reaching out frantically with its red root hairs, to grab the tree.

hairy poison ivy vine

All climbing vines have some way to hold onto the surface they climb on. But no other vine in its territory has the distinct hairy vines that poison ivy has.

poison ivy wall

Drove past this garage and noticed a massive growth of poison ivy on the outside wall.

I stopped in to inform the owner that they had a potential problem out there. He was friendly and said he know about it. 

But see those thick, hairy vines? Nothing else has quite that look.
