When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Note on Smooth Brome One of the most common non-native species found at nearly every site was smooth brome (Bromopsis (Bromus) inermis). Smooth brome is not on the noxious weed list, yet it appears to be one of the largest threats to ecosystems, besides development, in Jefferson County, particularly in wetlands. Smooth brome is very difficult to treat without causing problems to the surrounding environment. Unfortunately, the spread of smooth brome is being encouraged by weed treatment activities especially in wetlands. Canada thistle is very common in wetlands, and is a B-List noxious weed. It is often treated with herbicides that impact dicots. Smooth brome is a monocot. A recent report by Rondeau (2011) found in a six year monitoring effort for Canada thistle (Cirsium arvense, also Breea arvensis) that although the treatments were successful in removing the Canada thistle it was replaced by smooth brome in wetlands where smooth brome was already in the area. In addition, they found the local native plants including woody species were being impacted as well over the six year study. Overall the result was a less desirable outcome than the situation being remedied from an ecological perspective. This is unfortunate because Canada thistle is a B-Listed plant; people are being required to treat it. If smooth brome is in the vicinity (which is often the case) a state listed noxious weed is being replaced by something that is even more difficult to control and arguably more damaging to the ecosystem. In the State of Colorado, smooth brome is available for use in seed mixes used by ranchers, homeowners and highway departments which is why it is not listed as an invasive species. This plant is considered to be an invasive species in at least ten other states (MN, OH, IN, IL, KY, TN, NB, WI, ND and MS), by Ivasives.org and The Nature Conservancy.
