Moths come in a variety of shapes, as this plume moth demonstrates. It’s National Moth Week. Find your own moth!  Here’s a guide  to attracting and identifying moths…and having a “mothing” event.


Wednesday’s Moth: National Moth Week 2017

Our National Moth Week species of the day is shown here in its caterpillar form. Meet the Goldenrod Hooded Owlet (Cucullia asteroides)!

The closest public event during National Moth Week to our city is at the South Shore Nature Center, this afternoon (Wed. July 27th). But check out this guide to finding moths.

All of our moth images this week are photographs shot in Cambridge. The image here was photographed at Fresh Pond Reservation by Tom Murray, author of Insects of New England and New York.

When you’re out looking for moths this week, include caterpillars. You can post a photo of it on or and ask for identification help.

A Victory for Clean Water: Citizen Science Data Leads to Change

The following news is reprinted with permission from the Mystic River Watershed Association:

For years, the Mystic River Watershed Association (MyRWA) and its volunteers have helped to document water pollution problems in the Town of Belmont. This week, that hard work paid off.

The U.S. Environmental Protection Agency (EPA) has issued an Administrative Order on Consent with the Town of Belmont over years of water quality damages. Over the next five years the town has agreed to make a significant investment in repairs to its storm water system, which is discharging pollutants, including human sewage, into waters of the Mystic River watershed. We congratulate Belmont on their commitment to improve water quality to tributaries to Alewife Brook.


This is a success story for citizen science and for non-profit environmental collaboration with government agencies. Data acquired by MyRWA volunteers and shared with EPA was key to making progress. This has been a group effort—from the dozens of volunteer monitors who go out each month to collect samples, to the tireless work of others like Roger Frymire, who spent countless hours finding sources of pollution in the Alewife Brook area.

Since 2000, volunteers through the MyRWA’s Baseline Monitoring Program have generated water quality data that is shared with state and federal agencies. Each year the EPA in conjunction with MyRWA issues a water quality report card for the Mystic River watershed.
The 2015 water quality report card for the Belmont area tells the story: Alewife Brook earned a D grade with 50% compliance with boating and swimming standards for bacteria; Little River a D- grade at 44% compliance; and Winn’s Brook an F grade at 33% compliance.

One powerful aspect of the Baseline Monitoring Program is that it is poised to document success as well as problems. As infrastructure repairs are made in Belmont, we fully expect these grades to improve. We look forward to documenting and celebrating water quality improvements to Alewife Brook, Little River, Winn’s Brook, Wellington Brook—and the Mystic River itself—over the next five years!

Congratulations and thanks to everyone who continues to work with us for protecting clean water.

Locals Offset Carbon Footprint to April 29 Climate March

If you’re traveling to Washington, D.C., for the April 29th People’s Climate March from Greater Boston, you can now offset the carbon footprint of your travel through a GreenCambridge program that will provide  education and support local urban trees, plants and climate through the purchase of biochar.soil for climate.jpg

About Biochar (from the International Biochar Initiative)

The 2,000 year-old practice of making biochar converts agricultural waste into a soil enhancer that can hold carbon, boost food security, and increase soil biodiversity, and discourage deforestation. The process creates a fine-grained, highly porous charcoal that helps soils retain nutrients and water.

Five Questions for Magazine Beach Advocates

On the fifteen-acre section of parkland between the banks of the Charles River and Memorial Drive, between the BU Bridge and the Riverside Boat Club, bird-watchers have identified no less than 94 species. This area, called Magazine Beach, also attracts a regular stream of walkers, joggers, bikers, boaters, and families using the state-run outdoor swimming pool. A powder magazine–built as a gunpowder storage facility in 1818 and converted to a bath-house in 1899—is slated for occupancy about two years from now. New landscape plans include a 10-foot multi-use path along Memorial Drive, a dock, two overlooks, stormwater-related improvements, and a splash deck and natural play features.

Cambridge Outdoors talked with Brian Conway and Cathie Zusy, members of the Magazine Beach Committee of the Cambridgeport Neighborhood Association (CNA), who have worked in recent years to champion the park’s revitalization.

1. What is the history of the parkland at Magazine Beach?

“It was originally an island surrounded by marshes but was turned into one continuous piece of land. It was a park created by the city. The Olmsted Brothers created a plan for the park inspired by Charlesgate Park, where the Esplanade is now. The Cambridge “city fathers” wanted something just like that—a water park and a “play ground for the young.” It was inspired by envy. But a financial panic in 1893 got in the way. 

All the parklands along the river were turned over to the Metropolitan District Commission in the 1920s for the purpose of consistent parkland management.

There’s a long history of people trying to make Magazine Beach better. There have been many different plans for the park over the years, most of which never were implemented. The last real improvements happened in the 70s, other than the 2009 city investment in new playing fields.”

2 What role has this (adjacent) neighborhood had in the history of Cambridge, and what is it like today?

“From the late 1800s to the mid-1900s, many immigrants lived in this part of Cambridge. There were many factories here and close by. Magazine Beach was created to provide a place where factory workers could cool off on hot summer days. Today, instead of soap, biscuit, candy, lantern and telescope factories, we have biotech and high tech companies. But the need remains: we all need “breathing spaces” to relax and revitalize along the river.”

3. Why is Magazine Beach an important place in your own mind?

“At 15 acres, it is Cambridge’s second largest park. It offers access to the river, old shade trees, cool breezes, the sky and the sunset. And it is the location of the oldest building on the Charles River Basin. As a community park, it represents the ideals of democracy—it is everyone’s green open space.  It is a mixing ground.”

4. Are there animals at Magazine Beach? What can people do there?

“In addition to the 94+ bird species, there are rabbits and squirrels. It’s a favorite dog walking spot. Single and double shells launch from there at the Head of the Charles Regatta. It’s used by pick-up soccer players, Cambridge Youth Soccer, Cambridge Central Youth Baseball, Youth Lacrosse, the Boston University Academy Quidditch team, swimmers, and rowers (at Riverside Boat Club).” [Note: Click here for wildlife sightings at Magazine Beach]

5. What’s the more recent history of the revitalization effort?

“The CNA has been working on the project since November 2010. For the past three summers, we’ve had a full roster of outdoor events at Magazine Beach.The CNA has been working with Massachusetts Department of Conservation and Recreation to revitalize the park and to restore it as a place of beauty. We’re committed not only to the revitalization of the park—we want to make sure its maintained. If there isn’t a “guardian” group, it may be forgotten.

With the help of Cambridge and private contributors, DCR has stabilized the exterior of the Powder Magazine. Cambridge just allotted another $100,000 to renovate the interior by adding public bathrooms and lighting, etc. (DCR will match this.)

The landscape is in design now. We hope to have “shovel-ready” plans by the end of the year. Then we need to find the money for park improvements.”
