Nonpoint Source Pollution Control 
Assistance is provided to agricultural producers
for pest and nutrient management techniques
which reduce the potential leaching of agricultural
chemicals into the groundwater.
Assistance is also provided to municipalities for
reducing pollutant loading into surface water
bodies from stormwater runoff.

NYSDEC Erosion & Sediment Control
Training
Under the NYS Department of Environmental
Conservation’s Stormwater Permit GP-0-10-001,
all developers, contractors, and subcontractors
must identify at least one trained individual from
their company that will be responsible for
implementation of the SWPPP, and have at least
one trained individual on site on a daily basis when
soil disturbance activities are being performed. 
In addition, developers must have a qualified
inspector conduct regular site inspections in accord-
ance with GP-0-10-001.
*Qualified inspectors and trained individuals must
have 4 hours of training in the principles and practices
of erosion and sediment control endorsed by NYS DEC,
\SWCD, or CPESC Inc.  (Training is valid for 3 years.) 
\Training is not required for CPESC, LA, and PE
certified persons.

LINPI
The Long Island Native Plant Initiative (LINPI) is a
progressive all-volunteer cooperative effort of over
30 non-profit organizations, governmental agencies,
nursery professionals, and citizens and spearheaded
by Suffolk County Soil and Water Conservation District.  
The mission is to preserve the genetic heritage of
Long Island’s native plant populations by conducting
\wildland seed collections, establishing commercial
sources of ecotypic (i.e., genetically native) seed and
plants for native plant production,  contributing seed to
a regional seed bank, fostering a demand for native
plants and serving as a propagation resource for the
nursery industry.  For more information or to become
a LINPI volunteer, please contact our office or visit.

Invasive Species
Invasive species are non-native (to the ecosystem in
which they are introduced) plant, animal, insect, or
microbe which causes or are likely to cause economic
or environmental harm or harm human health.  These
species are responsible highest declines in biodiversity
next to development and in 1998, it was estimated that
damages and subsequent control activities totaled over
$138 billion.   In an effort to help reduce the impacts of
invasive species on agriculture and biodiversity, the
District provides technical assistance on invasive species
identification and management to growers, agencies,
non-profit organizations and the general public.   Further
information on invasive species including the Suffolk County
“Do Not Sell List” can be found at the Suffolk County Invasive
Species Advisory Board link

Native Plants
Native plants are critical structure of natural habitats
providing food and shelter for pollinators, mammals,
and insects while protecting soil, water, and air
resources from erosion, pollution and degradation. 
The District provides native plant technical assist-
ance on selecting appropriate species reflective
of site conditions, plant requirements/tolerances,
and management goals for agricultural and habitat
restoration practices.
