This is a classic example of a French broom monoculture — a wall, a sea of broom, with no room for anything else to grow, and no views of the forest from within these green tunnels. Many of the trails in Redwood Regional Park (just a bowshot over the ridge from here) were similar green tunnels for long, stultifying lengths before the volunteer crews began restoration work there a few short years ago.
Or, green tunnels on the thicket’s surface. For here is what faces any native seed, plant, or critter behind that curtain:
Here is a quick panning view of the trail junction, broom thicket, and vicinity, taken with my camera phone (which is a handy backup for when the battery of one’s regular camera runs low):
And here is what is feels like to actually try to hike along a trail that the broom has commandeered. In the brief time that I was photographing this stretch, several groups of hikers chose to take alternate paths after looking at this one:
This is one of the main reasons people clear broom.
