Houston Wilderness volunteers and staff plant 120 native “super trees” at the Bayport Terminal Berm, concluding the planting of 1,500 trees there, on Friday in Seabrook. “Super trees” are trees with high rates of carbon absorption, flood mitigation and greenhouse gas absorption. The effort is part of the local nonprofit’s Gulf Houston Regional Conservation Plan, which calls for a 4 percent increase in organic carbon absorption every year to benefit air quality and help reduce urban heat spikes in the region.
