Disclaimer for Atlas Trips: These trips are designed to generate complete species lists for specific areas. Target attendees are those with high levels of plant identification skills. They are not recommended for the general public as most of the time will be spent keying plant species and compiling lists. Regular field trips will provide much more enjoyment as they are designed for the general plant enthusiast.

How Did Non-native Plants Get to Oregon - Barb Wilson

Non-native plants have arrived in Oregon in a variety of ways. Written records concentrate on deliberate introductions, and many of our naturalized plants were brought here as crops, ornamentals, medicines, or for soil erosion control. Examples include food crops such as Himalayan blackberry (Rubus discolor); hay crops such as timothy (Phleum pratense) (A single bushel was brought overland in 1825); Fuller's teasel (Dipsacus sativus) cultivated in Clackamas County (the only center of cultivation west of the Mississippi) to raise the nap on wool cloth; medicinal herbs suc as tansy, mint and catnip; gorse for fencing sheep; clovers planted to fix nitrogen; and European beach grass (Ammophila arenaria) for controlling the movement of sand dunes.

Perhaps more intriguing are the species introduced unintentionally. An overlooked apple core initially brought in by mistake in the late 1820's became the progenitor of Oregon's first Orchard.

An interesting variant on the theme of accidental introductions involves an extension agent who sent letters to ranchers in the Intermountain West, asking whether or not certain serious weeds had become established in their areas. To ensure correct identification, he included a sample of each weed. Seeds from those plants helped expand their range.

No doubt a variety of seeds were introduced as contaminants in crops, a process that continues today. Before 1880, cheat (Bromus secalinus) was introduced as a contaminant of rye, but for a time cheat itself was cultivated as a forage crop. Just this year the first Oregon record of the sedge Carex chordorrhiza was reported from a cranberry crop established from Wisconsin stock.

Livestock are effective plant transporters, carrying seeds entangled in wool or hair, stuck in hooves, or in the digestive system. Horses brought overland from the Midwest probably brought some seeds, but probably more important were drives that, beginning in 1841, brought hundreds of cattle, sheep and horses north from California. These animals must have brought seeds of the Mediterranean plants that were already transforming California's grasslands.

Farm equipment can carry plant propagules between farms and occasionally across long distances. About 1872, a thresher that was brought from the East introduced Canada thistle (Cirsium arvense) to Marion County.

Traveling long distances quickly, railroads have been important in the spread of major weeds like downy brome (Bromus tectorum) and minor curiosities like Oregon's only record of wild hair fescue (Festuca filiformis).

Ships are perhaps less important transporters of land plants now than they were when they took on soil or sand as ballast. In 1915, James D. Nelson reported 213 species on ballast at Linnton (now an industrial area of Portland). Over 60 of them, such as iceplant (Mesembryanthemum crystallinum) and sand sedge (Carex arenaria) were new to Oregon.

As you can see, plant species can arrive in Oregon in a wide variety of ways, and they continue to arrive.

Clarkia Seeds Sought

Bill McMillan of Nanaimo, B.C., is conducting research on Clarkia amoena (all varieties), and would like to build a collection from many populations. If you can collect plants that have mature seed capsules (or collect just the capsules), Bill will supply you with a stamped, addressed envelope in which to mail him the seeds. Bill's email is

NPSO World Wide Web Site Launched - Michael McKeag

The Native Plant Society of Oregon now has a site on the World Wide Web at:

We hope the site will become a valuable communications tool for members, and a vehicle for reaching a wider audience, attracting new members, and providing educational content to schools and anyone else interested in native flora.

The "wired" among you are invited to visit the site, and those not yet "on-line" are encouraged to take the plunge (the water's fine). Web sites are dynamic things, always under construction, always changing, and ours is no exception. The basic structure is in place, but there remains much to do in putting flesh on its bones. I'm sure you will discover "bugs" too. Let me know when you do. Offer suggestions for new content or improved form. And better yet, roll up your sleeves and help by producing and submitting your own content. I don't plan on keeping the site alive and dynamic single-handed. The Internet is a powerful medium for collaboration. We can now make it serve our purposes.
