The Pine Barrens: How Trees Protect Our Water

Save The Great South Bay warmly welcomes guest blogger, Katie Muether Brown, Deputy Director of the Long Island Pine Barrens Society on how our Pine Barren trees help protect our waters.

Colloquially, the piece of legislation that protected over 100,000 acres of Pine Barrens land, is referred to as the “Long Island Pine Barrens Protection Act.” But, that’s not its formal title! It actually has two formal titles – the “Long Island Pine Barrens Maritime Reserve Act” and the “Peconic Bay Region Watershed Protection Act.” It’s Article 57 of New York State Environmental Conservation Law.

The Act, which passed the NY Legislature in 1993, declares:

“The legislature hereby declares it to be in the public interest to protect and manage the Pine Barrens-Peconic Bay system, in the county of Suffolk, by establishing a Long Island Pine Barrens maritime reserve.”

Well then, what does the preservation of acres of trees have to do with water? The Act’s formal name reflects the Pine Barrens’ important role in protecting our ground and surface waters.

This led the federal Environmental Protection Agency to designate our aquifer system as the nation’s first Sole Source Aquifer, requiring special protection. The quality of our drinking water depends, therefore, on how Long Island’s land is used. The more land is used for homes, lawns, agriculture, business and industry, the greater the contamination of our aquifers.

Long Island’s aquifer system is not static – they slowly flow from high ground to low, are recharged by rainfall, and they supply the majority of fresh water entering our streams, lakes and bays. The Pine Barrens contain portions of the watersheds of two major rivers – the Carmans and the Peconic. The region also interfaces with the Peconic Estuary and the South Shore Estuary Reserve.

Outside the Pine Barrens, water pollution is rampant. Nitrogen pollution from wastewater and fertilizer use on lawns and farms is entering our aquifers and eventually, flows into our bays, rivers, lakes and streams. There, the nitrogen pollution fuels the growth of harmful algae blooms, which are devastating our marine ecosystems and our economy.

As scientists survey the levels of nitrogen across Long Island, one fact is abundantly clear: while groundwater beneath the densest developments on Long Island have the highest nitrogen level, the Pine Barrens Core Preservation Area has the lowest levels of nitrogen on Long Island. Preserving the Pine Barrens protected the largest quantity of the purest drinking water on Long Island.

Saving the Long Island Pine Barrens protected the habitat of thousands of plant and animal species, many of which are rare and endangered. It also gave us humans an untouched natural place to enjoy and explore. However, perhaps the most important feature of all, protecting the Pine Barrens was vital to protecting our water quality. It’s also why we must work to save what open space is left!
