Just in time for Tuesday's free guided Harrier Meadow walk, 20 students from the Ecology Club of St. Joseph Regional Prep in Montvale spent the better part of a day last week cleaning up the 70-acre site.

They picked  up several contractor bags' worth of trash and found was weird flotsam that came in with the tides (12 feet of nautical rope — still looped — a McDonalds Happy Meal toy, shotgun shells, a bowling pin, a doll leg, a Doll's head, a 10- foot piece of rebar, and light bulbs.

The work crew also cut back some of the runaway groundsel to restore part of the Harrier Meadow meadow. (Thanks, St. Joe!)

Seen at Harrier Meadow on Friday: More than 200 Greater Yellowleg, 8 Dunlin, a Spotted Sandpiper and a Wilson's Snipe.

Details of the walk follow.
