Beginning as soon as the week of April 15, WSDOT will perform geotechnical investigations in the Union Bay Natural Area (UBNA). Crews will be taking soil samples and installing monitoring well equipment in and around the parking area to study soil and groundwater conditions. The information gathered helps us better understand the composition and characteristics of the ground in this area to prepare for future wetland mitigation work.

According to Cliff Mass, UW meteorologist, our past winter of 2012-2013 was the most “boring” on record. There were no major weather events such as wind storms, artic blasts, snowfalls in the lowlands or major flooding. This was indeed good news for the UWBG horticulture staff.

The Red or Swamp Maple, Acer rubrum, is always noticed for its intense flame color in the fall, but I love these trees best right now – when they are covered in flowers prior to foliation.
From a distance the light gray bark of the tree sets off the pink & maroon flowers creating a stunning effect – it’s as if the tree is full of red fuzz.

Fine-textured foliage, long thin flower clusters and drought tolerance make these evergreen shrubs very popular.

If you have walked around Shoveler’s Pond in the Union Bau Natural Area this month you have seen the area undergoing a flurry of activity from plowing to bulldozers moving dirt.

The January 2013 edition of BGjournal features an article on the restoration work UW students have accomplished as part of the Restoration Ecology Capstone course sequence. The capstone works with community partners to accomplish restoration projects in and around Seattle. Capstone projects have helped to restore 15 acres of the Union Bay Natural Area, a former landfill.
