Sediment Pollution

Excessive Amounts of Sediment:

1. Damage stream channels, flood roads and property,clogs infrastructure, and pollutes drinking water

2. Smothers and pollutes insect larvae, fish eggs, andother aquatic life at the bottom of the food chain.

3. Reduce sunlight needed by underwater grasses, fish,crabs, and oysters.

Background and Purpose

• Rising water levels from storms and tides• Exacerbated by Hampton’s broad network of waterways

• Both fresh and salt water issues

• Trees process huge quantities of water daily• Moving from roots to transpiration via leaves

• Some trees are well suited to sites with extra water• Careful selection can mean beauty as well as water absorption

• Not to mention other tree benefits (cleaner air, shade and privacy, e.g.)

• Will also work toward functioning habitat rather than bland yard

• We will consider site functions and some appropriate trees• With a short review of planting principles

Site Characteristics to Think About

• Question 1: Standing water at any point during the year• How often? How long does it last? Is any of it brackish?

• Question 2: How much space is there for woody plants?• Above and below ground

• Also consider ornamental grasses (fibrous roots) for smaller spots

• Question 3: What is the sun/shade profile?• Full: 6+ hrs daily; Part 2-6 hrs daily; Shade less than 2 hrs daily

• Question 4: Any other homeowner desired tree functions? • Flowers, fruits, habitat friendly for birds, insects etc?

• Evergreen or deciduous?

Understand Tree Roots• Root Spread: 2-3 times canopy width, 3-6 ft deep usually

And Then There Is Salt

• Salt Tolerance: • Most plant descriptions assume fresh water only, have to do research

• Winter road salting can be a problem if allowed to contact most plantings • Salt tolerant plant buffers or hardscape can protect other plantings

• Some plants can handle salt wind but not soil salt

• Occasional saline soils from storms limits plant selection somewhat• But there are some good choices for our wet sites

• Regular salt intrusion from seaside location means specialized plants only• A separate topic from today

Some Tree Suggestions

Water runs off to Street Standing Water Sometimes Standing Water Often

Native Small Trees(to 35’)

American Fringe Tree *Chionanthus virginicus

Yaupon Holly *Ilex vomitorium

Eastern Redcedar *Juniperus virginiana

SassafrasSassafras albidum

Sweetbay Magnolia *Magnolia virginiana

Black WillowSalix nigra

Native Canopy Trees (35 to 70’)

Sycamore Platanus occidentalis

American Persimmon *Diospyros virginiana

Red MapleAcer rubrum

Oaks: Willow, Pin, WaterQuercus phellos, palustris, nigra

Bald Cypress *Taxodium distichum

* = At least some salt tolerance

These native trees are found in bottomlands and along streams in the SE US-- They have adapted to the lower oxygen availability in such soils-- This is just a sample: consult with RAIN folks for other choices

Brief Look at Tall Trees (1)• Bald Cypress, Taxodium distichum, drought-hardy swamp tree

• H 70-100’ W 20-35’, deciduous conifer, full sun

• Has ‘knees’ in wet ground, roots can live submerged in fresh water

• Will tolerate salt in soil and spray

• Major habitat for many birds and other wildlife

Brief Look at Tall Trees (2)

• Sycamore, Platanus occidentalis, known for its beautiful bark

• H 70+’, W 30-40’, habitat for birds, insects and other wildlife

• A superior urban street tree, tolerates many tough situations

• Found in nature along stream banks and river bottoms

Brief Look at Smaller Trees (1)• Sweetbay Magnolia, Magnolia virginiana, a very versatile native

• H 10-40’ W 10-20’, semi-evergreen here, sun to part-shade

• Clay/loam/sand ok, also tolerates some soil salt

• Leaves, flowers, fruit as Southern Magnolia but all smaller

• Food source for tiger swallowtail butterfly larvae

Brief Look at Smaller Trees (2)• American Fringe Tree, Chionanthus virginicus, sturdy specimen tree

• Delicate flowers create a stunning spring display

• Supports hummingbirds, other birds and butterflies

• HxW 20’, minimal maintenance, naturally rounded shape

• Full sun to part shade, normal to moist soils, some salt ok

Planting Guidelines• Find the root flare (where trunk transitions to roots) and check roots

• If soil is compacted in pot, water the plant thoroughly the day before

• Cut off outside matted roots and feel for large circling ones (cut at bend)

• Dig hole same depth as root ball, 2-3 times the width• Root flare needs to be at ground level

• If ground is actually wet, plant up to 1/3 higher and create broad mound

• Refill hole with same soil as that removed• Water in, then mulch up to 2” depth

• Shredded bark mulch is ok, bark nuggets or pine needles are better

• Be sure trunk is not covered by mulch

• Water daily first week. If spring planted, water weekly until fall.
