As of tomorrow, the livestock will have been at Walden Woods for a week! We moved them to their third paddock today - my Dad helped me with the move, as did Taff (our oldest border collie). They did a great job on the annual grasses and cleaned up most of the poison oak, too. I forgot my camera today, so I don't have photos of their efforts.
Based on what we have left, I estimate that the job will take about two weeks. When we come back for our second pass through the common area in July, I'll bring older ewes and more goats, which should have a greater impact on the poison oak.
