Earth Calendar for April 22nd and April 23rd

  

Friday, April 26th is National Arbor Day, a holiday in which individuals and groups are encouraged to plant and care for trees.

The first Arbor Day was held on April 10, 1872 and an estimated one million trees were planted on that day. Trees not only add beauty and value to our landscape, they also provide many environmental benefits. In one year, a single healthy tree has the same cooling effect as ten room-sized air conditioners running continually, absorbs 750 gallons of storm water and filters 60 pounds of pollutants from the air. Trees absorb odors and pollutant gases and filter particulates out of the air by trapping them on their leaves and bark.Shade from trees slows water evaporation from thirsty lawns. Most newly planted trees need only fifteen gallons of water a week. As trees transpire, they increase atmospheric moisture.Trees also help prevent water pollution by reducing runoff by breaking rainfall, allowing the water to flow down the trunk and into the earth below the tree. This prevents stormwater from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.Citizens are encouraged to celebrate Arbor Day by planting a tree at home. Adding deciduous trees on the south and west sides of your home provides shade during the summer, reducing cooling costs. Planting evergreen trees along the north and west sides of your home will block chilly winds. The Arbor Day Foundation provides more information on their website.
