Tree Rounds (Tree Cookies)
Acorn Naturalists offers a wide range of heat-treated tree limb cross sections procured from tree trimmings. These quality rounds range in size from 2" to 5" across by 1/4" to 1/2" thick. The rings on these cross sections vary in size and appearance depending on variations in climatic conditions where they grow and species variations. Oak species always show characteristic radial rays. Tree rounds provide an ideal hands-on resource for introducing students to botany, forestry, dendrology and methods scientists use to determine past climatic conditions. Also available are tree rounds for creative art projects.
