New Finds Along Stream Banks and Wetlands
Droughts are not uncommon on the Western slope of the Rockies and, after several years of fairly average rainfall, this summer has been dry and hot. Last winter’s snowpack melted off by late July on all but the highest ridge lines and sheltered cirques. And less than two inches of rain has wetted the Crystal River Valley since the beginning of May.
A fellow wildflower enthusiast who has hiked the backcountry for over 20 years told me that she had never seen the upper Yule Creek basin so dry. There have been Stage 2 fire restrictions (no campfires anywhere) for weeks and the air is acrid from blazes to our west. In the August issue of the Crystal Valley Echo, Gentrye Houghton writes that “[w]e are walking through the ghosts of trees, breathing in the last beautiful sigh of a dying landscape.”
Most plants thrive on water and wildflowers are no exception. Wilted leaves, parched brown meadows and absent blooms have been all too evident along forest trails and montane vistas alike. My local patch of rare white Campanula parryi has been one casualty. (See below.) But I also searched in vain on familiar ground for Adoxa, Skullcaps, Blue- eyed Grass and Shooting Stars.
Will the soil harbor sufficient rootstock and seed to replenish these blooms if there is more moisture next year? It will bear a close watch. As will tracking the competitive balance between a number of other native species (e.g. Coneflowers, Paintbrush, Northern Bedstraw, various goldenrods) vis-a-vis what may be more drought resistant non-natives (e.g. Oxeye Daisy, Scentless Chamomile, Houndstongue, Canada and Musk Thistles).
Resigned to the facts, when it came to counting new species I concentrated my search on the valley’s wetlands and stream banks. That proved to be fruitful while affording more than one refreshing dip along the way. By mid-August, I was able to photograph over a dozen additional finds. A selection appears below.
Per the photos, most of these flowers have a green or brown inflorescence and hence are often overlooked or ignored (as non-flowers) for want of buzzy pollinators, showy petals or any eye-catching hue. But don’t be misled. While often camouflaged among willow breaks, once sited the iconic reeds, rushes and sedges that mark our local wetlands and stream banks can be as enchanting as any delicate alpine bloom. Moreover, they play an invaluable ecological role in anchoring local watercourses and providing food and forage for wildlife.
What’s the difference between reeds, rushes and sedges? Sedges have edges with triangular or three-sided stems and leaves in three vertical rows; the stems of reeds and rushes are round. That’s one of the main physical differences. Rushes are also in a separate botanical family (Juncaceae) from reeds which are part of the grass family (Poaceae); the round stems in Juncaceae are jointed, another distinguishing characteristic.
Plants in both families are wind pollinated as are sedges (Cyperaceae). And, yes, the flowers of sedges, reeds and rushes are hard to parse because the main reproductive parts (pistils and stamens) are usually tiny. A hand lens can help. For further research, try Wild at Heart by Janis Huggins which has detailed diagrams of the flower parts found in these three families.
The Crystal River valley’s wetlands are also home to a several members of the Ranunculus (Buttercup) family that may rarely be seen trailside. I have included two new finds at the end of the photo section.
