Schoolchildren and other volunteers are scattering more than 3 million loblolly pine seeds across South Carolina in an effort to help mitigate the effects of disastrous flooding statewide. The Earth Day event announced Thursday by Gov. Henry McMaster and South Carolina Floodwater Commission Chairman Tom Mullikin is the first tree planting effort of its scale statewide. The officials said the trees are one of a number of solutions that emerged from a 2019 by the commission addressing flood risks. The seeds were originally packaged to be planted last year but the pandemic put a pause on the event. The loblolly pine was chosen for its prevalence across the state.
