Underneath the scotch broom, Douglas fir seedlings, and poison oak, somewhere there was an oak savanna. The first thing the Conservation District did was to bring in a machine called a skid steer shear. Which pretty much does what it says. This versatile piece of equipment mowed between the trees, then cut them at ground level and stacked them into slash piles.
After the radical surgery, one more pass with the mower, and the first phase was done. Immediately after mowing it looks pretty raw, but shortly will recover with grass and wildflowers released from the overstory. The work pictured here was done in 2007.
Scotch broom is a non native invasive plant, originally thought to be a good plant for erosion control. It only belongs where it is native, and that’s not here! Introductions by well-meaning people often turn out to be really bad ideas, and this one was a major ecosystem destroyer – altering soil nitrogen and competing aggressively, with a seed bank that lasts for many decades. After the mowing, constant weed control of the resprouts and seedlings will continue for years and years.
