SILVOPASTURE

• Integrates trees, forage and livestock

• Environmental issues, i.e., biodiversity, watershed and scenic beauty are critical

SILVOPASTURE

•Grazing goats make beneficial use of a vegetation resource

• Tool to manage forest trees and their understory

• Tree are combined

• Improved pasture

• Forming an integrated

• Intensive animal husbandry

In Silvopasture

Why Silvopasture?

• A tool designed to improve income opportunities on farms and ranches

• Timber, pasture and livestock are managed as an integrated system

Planning Considerations

• Explore economic and environmental issues

• Explore local land use, zoning, cost-share and tax regulations

• Other implications

Plant Considerations

• Potential markets

• Explore soil types

• Climatic conditions

• Species compatibility

Plant Considerations

• Select and use trees and planting/harvesting patterns

• Suitable for the site

• Provide desired economic and environmental returns

Livestock Selection

• Cattle, sheep, goats, horses, turkeys, chickens, ostriches, emus, rhea, deer, elk, lamas etc.

• Be careful with browsing animals

• Broadleaf trees are more prone

A silvopasture practice diversifies farm income; can

minimize the need for chemical or

mechanical vegetation control; and can reduce hay and

feeding costs for livestock.

• Trees are managed for high-value sawlogs

• Trees provide shade and shelter and forage

• Based on spacing

BENEFITS

Cattle fertilize these pecan trees with nitrogen and it causes the grass to grow. By grazing, cattle gives extra profit from the beef. Helps where we don't have to mow as much.

• Tree species selected for a silvopastoral practice should be marketable, including

• Wood and other products such as nuts or fruits, offering another source of income in addition to livestock.

In a rotational grazing system, a successful silvopastoral practice

requires understanding forage growth and

managing the timing and duration of grazing to

avoid browsing of young tree seedlings or the elongating shoots.

ROTATIONAL GRAZING

Cattle are rotationally grazed among single, double and triple rows of pitch pine / loblolly pine hybrids and black walnut trees. The pines, planted on either side of the black walnut trees, help train the black walnut trees to grow straight for high-quality lumber production.

• UMC- Center for Agroforestry is working to reduce hay costs and extend the livestock grazing season through silvopasture practices.

• Winter hay costs for feeding one steer can reach $91; the managed grazing practice of silvopasture can reduce this amount significantly.

• Well managed silvopastures can reduce winter feed costs by approximately 20%.

GRAZING COSTS

http://www.centerforagroforestry.org/practices/sp.asp

1. Tree harvesting, thinning and pruning

2. Fertilization

3. Planting legumes for N fixation

4. Rotational Grazing/burning

5. Water resources

6. Fencing and others

MANAGEMENT TOOLS

1. Provide income from Livestock sales

2. Selective sale of trees and timber products

3. Forage enhance livestock growth and production

4. Other secondary products

A BUNDLE OF BENEFITS

1. Wildlife diversity and water quality

2. Enhance soil fertility

3. Enhance park-like setting

4. Less concerns of odors, dust, noise and diseases in contrast to concentrated livestock operations

ENVIRONMENTAL BENEFITS

1. Fencing costs can be very high

2. Crooked high quality hardwoods

3. May involve intensive pruning
