| Gold Hill Invasive Weeds: Questions
Why are we talking about this? Ecosystem concerns and federal/county mandate. Invasive weeds that are federally mandated for control by each state are called noxious weeds. They are the ones that have a tendency to take over at a large scale in receptive environments and create stable monocultures that detrimentally affect agriculture, along with other types of land. They can also take over whole areas on forest floors, but appear to be less invasive at higher altitudes. |
Is there a Weed ID and management guide for Gold Hill?
Boulder County Mountains Weed Management Guide
There’s not one for Gold Hill specifically; this is for the BoCo mountains in general.
Please note: this guide does not replace the Colorado site below.
good photos and information.
Why the state list?
There could be weeds up here that are not on the county list, but on the state list.
The state list gives you the life cycle of the weed. Mitigating the weed during its most vulnerable stage in the life cycle–and always before going to seed or at least seed dispersal–is necessary for control.
What about herbicides: Many of us here don’t want to use herbicides out of concern for pollinators on our own and neighbors’ properties as well as soil and water contamination–and we don’t have to. Mowing and hand pulling and re-seeding where possible are exercise-friendly options. When and how to do it is different for each plant. See the ID on life-cycle and talk with the Weeds Committee if you’d like to discuss a range of practices best for you and the land you care for.

Which of these noxious weeds plants are edible or medicinal?
Or have been used for other purposes–fodder, fiber, crafts by other cultures?
Dr. Duke’s Phytochemical and Ethnobotanical Databases
Dr. Duke was a well-known, respected, and loved ethnobotanical researcher
And author of many books on the ethnobotany of crops and weeds such as Handbook of Edible Weeds. Look your plant up in this database.
Plants For A Future (PFAF) Database
This is also a respected website, which uses Dr. Duke’s work among others. Many websites with plant profiles copy from each other (the language is the same) and many copy from PFAF. So start with PFAF.
Native American Ethnobotany Database
This is based on the 927-page book of the same name by Prof. Daniel E. Moerman
It’s a compilation of anthropological information given by indigenous informants to
researchers over the years.
This is the National Library of Medicine of the National Institute of Health,
where professional herbalists and research geeks go to find out what cool research
has been done on your plant over the years, all over the world.
