APT Invasive Plant Removal Work Party

Help keep the refuge clear of invasive plants! On Saturday, April 22nd, APT (Assabet Pulling Together) will be working from 9AM to Noon. Meet at the Visitor Center parking lot.

Garlic mustard, one of our early spring invasive plants, is growing well and some plants are close to flowering so time to work on it. This year we will be doing our normal hand pulling and trying other techniques on some areas such as black plastic and horticultural vinegar. We will be working on other invasives as well.

Wear long pants and bring insect repellent, sunscreen and water. APT will provide disposable gloves for working on the garlic mustard. A weed remover is useful for removing the larger garlic mustard plants.

Note that volunteers need to complete a Volunteer Service Agreement yearly. Special APT forms with the government part completed will be available at the work session and can be completed at that time but if the volunteer is 18 or younger a parental signature is required before the volunteer can work.

Please email Dave Lange if you can help, but last minute drop-ins are also welcome! Thanks to our hardworking volunteers. Let's keep making room for natives!

Sustainable Sudbury Movie Night featuring Bag It

Americans use 60,000 plastic bags every five minutes that are then thrown away. But where is “away”? Where do the bags and other plastics end up, and at what cost to our environment, marine life, and human health? BAG IT follows everyman Jeb Berrier as he navigates our plastic world, discovering that virtually everything in modern society is made with plastic or contains potentially harmful chemical additives used in the plastic-making process. The recipient of numerous film festival awards, BAG IT is an eye-opening documentary.

Sustainable Sudbury is an environmentally focused nonprofit organization based in Sudbury, Mass. It is a chapter of the Massachusetts Climate Action Network (MCAN) and is dedicated to raising environmental awareness and sponsoring sustainable, earth-friendly activities in our community and beyond.
