Maple Sugar Days return in the Blackstone River Valley National Heritage Corridor on Saturday, February 25 and Sunday, Febrary 26, from 11:00 a.m. to 2:00 p.m. at River Bend Farm, 287 Oak St., Uxbridge. No reservations are required.

■An EnviroScape Training Skills Workshop will be held on Wednesday, March 22nd from 6:30 to 8:00 p.m. at the Corridor’s office, 670 Linwood Ave., Whitinsville. The EnviroScape is an interactive tabletop teaching tool. Educators can demonstrate how pollutants affect a watershed. With food, sprinkles and other pollutants, the EnviroScape illustrates how fertilizers, pet waste, oils and toxins can be introduced into our watershed. Why learn how to use an EnviroScape? The Corridor has many requests for this program, and on World Water Day we want to build a cadre of knowledgeable volunteers so that the EnviroScape can visit elementary schools, public programs and scout troops. No previous experience with science is necessary. VIP Julie Riendeau will serve as trainer. RSVP to https://bit.ly/EnviroScapeSW.

■A Bark, Branches and Buds Winter Tree and Shrub ID Walk will be held on Saturday, March 25 from 10:00 a.m. to noon at Blackstone River State Park, 1075 Lower River Road, Lincoln, Rhode Island. RSVP to https://bit.ly/BarkBranchesBudsWalk.

■Volunteers as the backbone of the Blackstone River Valley National Heritage Corridor has never been more apparent than it was on January 16th when more than fifty worker bees came out for the MLK Day of Service at five different sites. The Asa Waters Mansion and the Grass Hill Schoolhouse in Millbury, Hearthside House in Lincoln, Rhode Island, the Woonsocket Historical Society and the North Smithfield Heritage Association partnered to host a cleanup of the Mammoth Mill Ruins. To learn more about the history of the Asa Waters Mansion and the Grass Hill Schoolhouse, check out VIP Abigail Epplett’s blog at https://abbyeppletthistorian.blogspot.com/2023/01/MLKDayofService-AsaWatersMansion-GrassHillSchool.h.... Another Corridor volunteer, Angelo Mirabile, helped with record keeping of volunteer files at the Corridor’s office.
