We moved into the last unit on this project today - one more move and we'll be through. We've learned that we need to push the envelope a bit to get the sheep and goats to consume the poison oak this time of year. Since everything else is still green, the poison oak becomes one of their last choices. To get good consumption of the poison oak, we take the chance of having sheep go through the fences in search of more palatable feed. So far this hasn't happened yet, but we're not getting uniform impact on the poison oak.
We'll have the animals back on the site in July. At that point, the only green vegetation will be poison oak, and suspect we'll have much better consumption. We'll see!
