Wildlife: Animal den?, NB1

The section of the Nashoba Brook watershed designated NB1 runs from the downstream end of Ice House Pond, at Concord Rd., to the Concord town line. This section has great potential, and, unfortunately, equally great problems.

NB1 has probably the heaviest commercial development along the brook's banks of any section, yet is still is very useable and clean. There are, however, some particular areas of concern.

1) The construction dump along Wetherbee St. is the biggest problem. A landowner has used the wetlands along the streambed as a site to store his construction equipment, and it now includes a great deal of large, useless machinery, cinderblocks, and other construction debris.

2) The general level of trash along the streamside is high in this area, and needs a good clean-up effort.

3) Because of the heavy commercialization, many sites along the brook experience run-off problems from gravel or tarred driveways.

Because it is at the downstream end of the whole watershed, the brook is widest in NB1, making for the possibility of canoeing much of it. Unfortunately, the streambed has filled in with brush, which, while a natural occurrence, makes much of the length impassable. Clearing out this brush would increase the usability of the brook in this area. The abandoned railroad bed runs along much of this section, and converting it into a hiking and biking trail would improve access to the brook, increase the usability, and reduce the amount of trash and litter discarded along its banks.

In the long run, the Acton Stream Team could probably have its greatest impact along this length of the Nashoba Brook.
