Trying out a new tool-
Weed Watchers Guide for the Tualatin River Watershed is a handy tool for identifying EDRR weeds. (It’s presented at a Weed Watchers Workshop, to train local folks how to identify and report invasive plants that have the potential for being eradicated through Early Detection and Rapid Response).
- I’m relieved that none of the Class A weeds are in my yard.
- One is in the guide, in the “Secondary Target” category: Lesser Celandine
The other known invasive plants in my yard are beyond the scope of an “Early Detection and Rapid Response”
- Armenian/ Himalayan Blackberry
- Reed Canarygrass- is so widely spread, I wonder if this announcement by Oregon Invasive Species Council relates to our infestation. I will check with the SWCD*.
“Record of changes to the list 2014- Removed common reed (non-native subspecies) – Lost the battle!
The subspecies is causing serious problems for many other North American wetland plants, including the native Phragmites australis subsp. americanus which is markedly less vigorous. Surveys now indicate that this subspecies is more widespread and in locations that would not be suitable for large-scale control programs.”
*06-30-15 note: Reed Canarygrass scientific name Phalaris arundinacea; different species
THE SOLUTION: encourage other wetland sedges, grasses, rushes, and cat-tails.
ARMENIAN/ HIMALAYAN BLACKBERRY
THE SOLUTION: removal of Himalayan Blackberries!!!
Planting and restoration of native berry populations like this relative of the raspberry- native Thimbleberries.
