Priorities of the Quad County/Colville Reservation

The following non-indigenous
weed species have been identified as priority targets for biological
control within Okanogan, Stevens, Ferry, and Pend Oreille Counties.
Currently, there are biological agents certified for release in the
United States that will attack Dalmatian Toadflax. The most effective
agent is not abundantly available yet, but representatives of the
Quad County Bioagent Project are actively pursuing its introduction
into this area. There are no approved agents for use against Houndstongue,
Yellow Hawkweed, or Orange Hawkweed in the United States at this time,
but they are being studied. There are, however, biological agents
presently used in Canada to fight Houndstongue. |
