| Resource Description
|
| WILLOW, RED TREE ROUND (Western Riparian). A widespread species, found throughout western states and north all the way to Alaska. A key species in moist areas, providing shelter for a wide variety of species. This high quality red willow cross section (disc or tree cookie) is perfect for studying seasonal tree rings to calculate the age of a tree or limb, identify tree anatomy (heartwood, sapwood, cambium and inner/outer bark layers), study different growth patterns (tree ring irregularities, evidence of branching) and variation in growth patterns and climatic variations over time. Each cross section is fine sanded on one side to assist in reading tree rings. Since there is variation among all of the rounds, looking at several specimens of each species provides for an optimal learning experience. Individual disc size ranges from 2” to 4” across by 1/4” to 3/8” thick. #T-18084.
