My standard creek-crawling kit - waterproof camera bag, black coffee, good gloves, and crackers.
I went down to the creek this afternoon and put in a little sweat-equity pulling ivy and archangel. In the process I took the time to remember the legacy of Sandy Diedrich, an environmental advocate who lead the charge against vast stands of English ivy that were enveloping large areas of her beloved SW neighborhoods in Portland, Oregon. I never knew her personally; she passed away a year or so before I got involved with the advocacy side of Fanno Creek issues. But she made a huge difference by recruiting, training, and inspiring a generation of wetland warriors. Her work goes on today and her legacy is celebrated annually in the form of Portland’s Environmental Stewardship awards. She – and all the other Watershed Folk back in Portland were much on my mind as I teased out stems and runners from the roots of ferns and the general detritus covering the banks of Beatty Creek.
Below, before and after photos of a small area (roughly 35 sq. ft.) covered with young English ivy. I suspect it washed down here from higher elevations just a couple months ago – the main part of its root system was mired in a mix of silt and gravel right at the edge of the embankment.
Next, a bit further downstream, before and after shots of one of the ubiquitous stands of archangel that crop up every 300 feet or so along the bulk of the stream. I know for a fact that it can be found as far upstream as the 500’ level about 1.5 miles from this site, which lies at 180’.
I haven’t completely finished work on this patch – still have a dozen square feet to work through. Archangel is way more time consuming to pull than English ivy; but like the ivy, it can propagate from mere pieces of stem or leaves.
I re-photographed the hogweed stand. It is thick on both sides of the stream in this area, and also well established a scant 100 feet further down the bank. If and when it is possible to round up some protective gear, I will try my hand at cutting it down and hauling out the remains. That will at least slow it down until a professional crew can come in and do a number on it.
Except for the hogweed infestation, the other two I worked on today were quite "minor," in the sense that the vegetation involved was both relatively sparse, and not yet deeply rooted - precisely the kind you most want to tackle. It's slow going because the goal is to tease out as many segments of root material as possible - have to work a strand at a time. If you try your hand at this sort of thing, make sure to pack along a couple hand warmers.
Below, one of the reasons why fighting back against invaders like ivy and archangel and hogweed and all the rest is so important. I don’t know just how these little stream violas figure in the overall scheme of things –what benefits they bring to the ecosystem and all that; but for now I’ll just work to preserve their place at the table. Maybe a little further downstream enlightenment will come….
