Driving through town I saw a NJ license plate devoted to conserving the Meadowlands, below is a photo from the NJ DMV, proceeds from the sale of the plate will be used to fund the Meadowlands Conservation Trust.

From the Trust: " The unique design of the plate combines human and natural elements to show our constant interaction in this urban wetland complex. This plate will help establish incentive programs to encourage land donations and protect open space to improve accessibility and recreational opportunities for the Hackensack Meadowlands and River Watershed."

Meadowlands..... you've come a long way baby.

Summer, this wonderful season of swimming, picnics, BBQ, mosquitos, posion ivy, and...Giant Hogweed? Seemingly straight out of the Jurassic age, the Giant Hogweed (Heracleum mantegazzianum) is not lightly named, living up to 25 years, with stalks reaching 15 feet tall and leaves up to 5 feet long. The plant is reminiscent of the familiar Queens Anne's lace (Daucus carota), which also falls into the carrot family (!) and whose sap has similar irritative properties. Giant Hogweed is considered a facilitative wetland plant, occurring both in wetlands and non-wetlands, generally along river beds, forest edges and other disturbed or border areas.

Beyond its impressive size, Giant Hogweed is notorious for its sap effects on skin - worse and longer lasting than than poison ivy. The sap sensitizes skin to the suns UV rays within 15 minutes, causing blisters to form within 24-72 hours, which can leave scars behind lasting months to years. The affected areas often remain sensitive to UV light, potentially leading to a recurrence of blisters years later. Even worse, if the sap if gotten in the eye, it can cause blindness.

The N.Y. Department of Health recommends that if the sap contacts skin, it be washed off with cold water immediately and either apply sunscreen or cover up the affected areas since this can prevent further reactions. The toxic reaction can begin as soon as 15 minutes after contact. If Hogweed sap gets into the eye, rinse with cold water immediately and put on sunglasses.

Giant Hogweed also is considered invasive, and quickly crowds out native species in areas it colonizes. In a dominant stand, up to 80% of incoming light is absorbed by its large leaves and flowers, shading out any species which fall under its canopy.

According to the NY DEC, the plant grows in New York, Pennsylvania, Connecticut, Ohio, Maryland, Oregon, Washington, Michigan, Virginia, Vermont, New Hampshire and Maine.

Hogweed control is difficult; it produces a prodigal amount of seeds, between 20,000 to 100,000 per year, which can remain viable for upto 7 years in the soil. Additionally, its large root can survive multiple cuttings. Control using multiple applications of herbicide over a few growing seasons is most successful. Additional info here:
