This week’s WoW is theÌýShort-Fruited WillowÌý(³§²¹±ô¾±³æÌý²ú°ù²¹³¦³ó²â³¦²¹°ù±è²¹)—Ìýa medium-sized shrub that grows in Å·ÃÀ¿Ú±¬ÊÓƵ’s moist meadows and wetlands of the subalpine and alpine zones (10,000-14,000 feet elevation).ÌýIt is widely distributed in the northern latitudes of NorthÌýAmerica and southward along the western mountains.ÌýWetlands dominated by willows are a rich habitat for songbirds, such as white-crowned, fox,Ìýand song sparrows, as well as Wilson’s, yellow, and orange-crowned warblers. Deer and elk like to browse the spring twigs.ÌýÌý
Willow habitat gives a new word for the week—carr. AÌýcarrÌýis a waterlogged wooded terrain that is dominated by shrubs rather than trees. It is part of a temporal ecosystem progression from wetland to forest.ÌýCarrsÌýtypically occur at the uppermost headwaters of our watersheds, serving as natural purifiersÌýof the water we drink.ÌýThe largest willowÌýcarrÌýin the Front Range is located in Boulder County along the North St.ÌýVrainÌýCreek1.ÌýÌýÌý
Over thirty species ofÌý³§²¹±ô¾±³æÌýare found in Å·ÃÀ¿Ú±¬ÊÓƵ—they are in the same family as cottonwoods (Family=Salicacaea; Genus=Populus). Both groups usually occur in moist habitats, with cottonwoods often being restricted to stream channels, and willows more widely distributed in wetlands, near springs,Ìýas well asÌýalong streams. Another difference between the two genera is Salix is pollinated by bees, while Populus is wind pollinated.ÌýÌý
The use of the willowÌýfor pain relief goes back thousands of years—it is the source of our modern aspirin. The effective ingredient fromÌýSalix isÌýsalicin, from which salicylic (sa·luh·si·lik)Ìý
acid was synthesized in the 19thÌýcentury. Traces ofÌýsaliciylinÌýwere found on 1,300-year-old pottery unearthed in eastern Å·ÃÀ¿Ú±¬ÊÓƵ2.ÌýOne might wonder if browsing animals also find some relaxing pleasure in their spring twigs.Ìý
Finally,Ìýyou might notice a small, folded envelope in the corner of this botanical specimen. It holdsÌýparts of the plant that are not easily taped or glued to the paper—most often seeds.Ìý
