ANIMAL ADVISORY COMMITTEE MEETING THURSDAY AUGUST 2ND AT 6:30PM AT CITY HALL: PIPING PLOVERS ON THE AGENDA.

Dogs romping within the clearly posted and cordoned off nesting area in April, forcing the Piping Plovers off the beach and to nest in the parking lot. 

This past spring and summer we had a tremendously difficult time with our nesting bird symbolic fencing. The posted and roped off area is referred to as “symbolic” because it is not an actual physical barrier, but a visual warning to let people know to keep themselves and their pets out of the cordoned off area. People often ask, why can’t more permanent fencing be placed around the nesting area? After nearly thirty plus years of working with Piping Plovers, biologists have established that physical fences placed on the shoreline and in the wrack area are all too easily washed away with high tides, create safety issues and, too, you wouldn’t want to trap dogs and predators within a nesting area.

The difficulty with our metal posts is that they were knocked about and pushed down with nearly every high tide, dragging the roping into the sand as well. The rope and posts needed almost daily righting.

The Massachusetts Department of Conservation and Recreation (DCR), which successfully protects Piping Plovers and other endangered birds at dozens of Massachusetts beaches have come up with what appears to be a good fencing solution for areas within tidal zones. DCR uses long, narrow fiberglass rods which can be pushed easily into the sand. The poles are strung with two rungs of roping, and in some places three rungs. I measured the distances between the poles at Revere Beach; they are placed about every twenty to twenty four feet.

In early spring, before the Piping Plovers and Least Terns have nested, historic nesting areas are roped off. After a nesting pair establishes a territory, a second row of poles and roping are added around the perimeter of the nesting area. The fiberglass poles can be adjusted without too much difficulty.

Wooden poles are used to post the nondescript, but informative endangered species signs. According to DCR staff, the only time they have complications with the fencing is when the wooden posts are tied into the fiberglass poles and the tide takes both down.

I don’t understand why the fiberglass poles are less likely to shift in the tide, but they don’t shift and appear to work very well in the tidal zone–perhaps because they are flexible and less rigid. If anyone knows the answer to that, please write.

PIPING PLOVER VOLUNTEER MONITOR GOOD HARBOR BEACH NESTING AREA FENCING RECOMMENDATION:

1. Symbolic fencing of the two historic Piping Plover nesting areas roped off between March 15th and April 1st (boardwalk #3 and boardwalk #1).
2. Fiberglass poles placed every twenty feet to twenty four feet.
3. One to two rungs of roping.
4. Wooden posts with endangered species signs installed at the same time and in place by April 1st, but not attached to the fiberglass poles.
5. When active nest scrapes are identified, adjust exisiting fencing, and add a second row of fencing around the perimeter.
6. To the outer perimeter of fiberglass poles, use three rungs of orange roping attached to the poles, extending all around the perimeter. One rung at 12 inches above ground, one rung at about 24-30 inches above ground level, and the top rung at four feet above ground level.
7. Piping Plover volunteers monitor fencing and adjust as needed.

This photo, taken at Good Harbor Beach in early April, shows why it is so important to have the signs and roping in place by April 1st. People and dogs were playing in the nesting area while the PiPl were trying to nest. The top photo shows that a second, and even a third rung of roping, placed at dog height, may help to keep dogs out of the roped off area.

Examples of symbolic fencing areas at Revere Beach and Nahant Beach. Notice the double row of fencing and the double and triple rungs.
