Why does my yard matter to a<br />
Red Drum?<br />
www.dnr.sc.gov
Why does DNR care about<br />
development?<br />
• Increased pressure on natural resources:<br />
200 acres <strong>of</strong> natural landscape are lost<br />
every day to development<br />
– Habitats are necessary for healthy water<br />
• Changes to environmental conditions:<br />
South Carolina is 40 th in size in the nation,<br />
but 10 th in the rate <strong>of</strong> land development<br />
– Land development changes environmental<br />
conditions<br />

Impervious Cover<br />
• Roads, ro<strong>of</strong>tops, parking lots, hard<br />
surfaces<br />
• Impede natural pollutant processing<br />
• Alters the rate, volume, and quality<br />
<strong>of</strong> freshwater and sediment inflows
Pervious Cover
What happens when water<br />
quantity and quality changes?<br />
Storm Event – 24 hr, 4.5 in. rainfall<br />
Urban – New Market (~50% impervious cover)<br />
Suburban – James Island (~21% impervious cover)<br />
Forested – North Inlet (~0%)<br />

On average, Charleston receives 50 inches <strong>of</strong><br />
rain each year.<br />
Your ro<strong>of</strong> size can be estimated by taking the<br />
square footage <strong>of</strong> one story <strong>of</strong> your home and<br />
garage.<br />
1 inch <strong>of</strong> rainfall on a 1,000 square foot ro<strong>of</strong> =<br />
620 gallons <strong>of</strong> water<br />
50 inches <strong>of</strong> rain per year on a 1,000 square<br />
foot ro<strong>of</strong> =<br />
About 31,000 gallons <strong>of</strong> water coming <strong>of</strong>f<br />
your ro<strong>of</strong> each year.

What happens when water<br />
quantity and quality changes?
So what can we do?<br />
– Install a rain barrel or cistern<br />
– Build a rain garden<br />
– Plant native landscaping<br />
– Increase tree canopy/protect trees<br />
– Install pervious surfaces<br />
– Scoop your pet’s poop<br />
– Pick up litter<br />
– Minimize fertilizer use<br />
– Compost your yard waste
Capture the Water Instead!
Rain Barrel Installation
Build your own Rain Garden<br />
• Allows collection <strong>of</strong> stormwater and infiltration<br />
• Plants and microbes do the work <strong>of</strong> pollutant removal<br />
• Can be attractor for birds and butterflies
Location, Location, Location<br />
• Intercept the water before it reaches storm drains<br />
• Gutters and downspouts help direct ro<strong>of</strong>top run<strong>of</strong>f flow<br />
• Driveway and sidewalk edges can also make good spots<br />
• Watch how water flows during a storm event
W<strong>here</strong> do we put the rain garden?<br />
• > 10 ft. from building foundation<br />
• > 25 ft. from septic system drainfield<br />
• In full to partial sun, if possible<br />
• Make sure to test the soil for<br />
its ability to drain<br />
1. Dig a hole about 6 inches<br />
deep and wide<br />
2. Fill the hole to the top with<br />
water<br />
3. Check if the water is gone 24<br />
hours later
What size should our rain garden be?<br />
1. Determine the area <strong>of</strong> impervious run<strong>of</strong>f source<br />
(ro<strong>of</strong>tops + sidewalks + driveway areas)<br />
2. Estimate the size <strong>of</strong> your rain garden by making<br />
it 20-40% <strong>of</strong> the impervious area (more for<br />
poorly drained sites)<br />
3. The excavated area should be 6-8” deep<br />
4. The area should be 8-10 ft wide – usually in a<br />
kidney bean shape
Now, what do I put in it?<br />
• Consider the existing soil for<br />
drainage and organic content<br />
• Rain garden soil mix:<br />
- Sand: 50-60%<br />
- Compost: 20-30%<br />
- Top soil: 20-30%<br />
• Plant with native species<br />
• Mulch cover at least 1 in. deep<br />
• Be sure to use pine bark or<br />
similar “non-floating” mulch!!

Land Use Change<br />
• Land use change<br />
– Population increase and<br />
sprawl →<br />
– Dramatic alteration <strong>of</strong><br />
landscape →<br />
– Impact on biodiversity and<br />
ecological processes<br />
• Human influence is<br />
inevitable<br />
• Can society and<br />
ecological integrity be<br />
compatible?<br />

• Native: One that originated in the area which it<br />
grows (Porcher and Rayner 2001)<br />
• <strong>Natural</strong>ized: Plants that are thoroughly<br />
established; yet are not native. Have not caused<br />
extensive damage or spread. Are more or less<br />
accepted as native (Porcher and Rayner 2001)<br />
• Exotic: Plants that have been introduced by<br />
human intervention to an area outside their<br />
native habitat (<strong>SC</strong>NPS)<br />
• Invasive: Introduced to an area, established<br />
breeding population, and spread to extent that<br />
damages agriculture or natural species. (<strong>SC</strong>NPS)
How are Invasive Plant Species<br />
Introduced?<br />
• Intentional Function<br />
• Accidental Transport<br />
• Gardening Efforts<br />
www.mdinvasivesp.org
Characteristics <strong>of</strong> Invasive Plants<br />
Species<br />
• Efficient dispersal <strong>of</strong><br />
seeds<br />
• Quick growth that enables<br />
to “crowd out” slower<br />
growing plants<br />
• Early sexual maturity<br />
• Similar climate as native<br />
range; however lack <strong>of</strong><br />
restricting agents<br />

Why Problematic?<br />
• 2 nd largest threat to native flora<br />
• Crowd out native species<br />
• Reduce biological diversity (and plants that wildlife<br />
depend on)<br />
• Interfere with natural succession<br />
• $35 billion in economic costs
