Phragmites australis - a poster child of invasives in the Peconics.

Help Us Stop the Spread of Alien Invasives!

We humans are often responsible for the introduction of new or spread of existing invasive species.  Fortunately, with a little care, we can prevent - and even reverse - the negative impacts of alien invasives.  Remember - please protect and restore the Peconics - Do Your Part!

If you're a gardener...

Never buy or plant non-native invasive plants that spread aggressively, such as purple loosestrife or bamboo. Instead, plant similar plants that are native and non-invasive and that thrive in the Peconics, such as the species included in the table below. Replace existing invasive plants with these same alternatives.

The following table of native landscape plant alternatives is taken from a publication of the Long Island Weed Management Area.
