World Wood Day
"World Wood Day is a cultural event celebrated annually on March 21st, same day as the International Day of Forests, to highlight wood as an eco-friendly and renewable biomaterial and to raise awareness on the key role wood plays in a sustainable world through biodiversity and forest conservation. This unique celebration reminds us all the importance and true value of wood and its responsible uses.
World Wood Day falls on the vernal equinox, March 21st, to symbolize the start of spring. World Wood Day was proposed by International Wood Culture Society (IWCS) and first celebrated in 2013 in Tanzania."
