Alabamas Best Management Practices for Forestry

• are voluntary guidelines to help maintain and
  protect the physical chemical and biological
  integrity of waters of the state.

4
BMPs are Designed to reduce and/or prevent NPS
Pollution.
Sediment (loose soil particles) Organic materials
(tree tops and limbs) Temperature (caused by the
removal of shade) Trash Pesticides and Nutrients
(herbicides fertilizers)
5
Responsibility
all those involved in the authorization,
planning and implementation of forestry
operations.

• Landowners
• Forest resource managers
• Timber purchasers
• Loggers
• Vendors

6
There are 7 Individual BMPs

1. Streamside Management Zones
2. Stream Crossings
3. Forest Roads
4. Timber Harvesting
5. Reforestation /Stand Management
6. Forested Wetland Mgt.
7. Revegetation/Stabilization

7
There are 7 Individual BMPs1. Streamside
Management Zones
8
Other names for Streamside Management Zones
(SMZs)

• Leave Strips
• Buffer Zones
• Wildlife Corridors
• Riparian Zones
• Hardwood Stringers

9
Streamside Management Zones
Things to Consider

• Width should vary (min. 35 feet)
• Protect from destabilization
• Maintain shade and organic recruitment
• Maintain forest floor
• Control logging debris, mech. operations,
  pesticides, fertilizers, trash

10
SMZ Illustration
11
Harvesting in a SMZ should be done so as to
protect the forest floor understory veg. from
damage.

There are 7 Individual BMPs

1. Streamside Management Zones
2. Stream Crossings
3. Forest Roads
4. Timber Harvesting
5. Reforestation /Stand Management
6. Forested Wetland Mgt.
7. Revegetation/Stabilization

13
2. Stream Crossings

• Avoid crossing streams if possible
• Use the fewest number as possible
• Locate and construct with least damage
• Install at right angles to stream
• Remove temporary crossings
• Stabilize and maintain permanent crossings

14
Log Crossings
15
Culverts
Make fill over a culvert the high spot in the
crossing.
Use adequate size
16
Proper Installation Is Critical

• Place culvert on stream bottom do not dig out
• Culvert should have 2-3 pitch downstream
• Compact lower half of fill during installation
• Provide for stream overflow away from culvert
  fill to prevent blowouts

17
Forded Stream Crossings
18
A geoweb ford, when properly installed can be a
good alternative to a culvert in the right
situation.
19
Bridges create the least disruption to stream flow
20
Portable bridges can be used for temporary stream
crossings
21
There are 7 Individual BMPs

1. Streamside Management Zones
2. Stream Crossings
3. Forest Roads
4. Timber Harvesting
5. Reforestation /Stand Management
6. Forested Wetland Mgt.
7. Revegetation/Stabilization

22
3. Forest Roads

• Proper planning and location is key
• Avoid problem areas
• Minimize soil exposure
• Stabilize exposed soil
• Close temporary roads
• Maintain permanent roads
• DRAINAGE, DRAINAGE

Ex Crowned road
23
Turnout ditches should be installed

• 3 slope 235
• 5 slope 180
• 10 slope 140
• 15 slope 125

25
4. Timber Harvesting
Things to Consider

• Develop a harvesting plan
• Location of landings
• Felling direction
• Proper skid trails
• Harvesting system
• Trash disposal

26
Selecting the right harvesting system is critical

5. Reforestation Stand Mgt. includes
recommendations on

• Mech. site prep (subsoiling on contour)
• Chemical site prep (follow label)
• Prescribed burning (stabilize firelines)
• Tree planting (machine planting should be done
  on contour)
