All clovers respond to rotational grazing
the taller, the better the response.
Most perennials are short lived in Texas.

Forage: Forage Leaves age reducing quality and photosynthetic efficiency
Bottom leaves are the oldest
Nutrients transferred to seed and carbohydrate reserve
best to maintain an LAI of 4-6
When to defoliate: When to defoliate When conditions are favorable
When target plants can afford to loss the protection
When target seeds need to germinate
Before target wildlife needs the food
After target wildlife doesn’t need the shelter
Defoliation Methods: Defoliation Methods Grazing/feeding: requires adequate numbers controllable vectors
Mowing: leaves a residue
Disking: disturbs the soil
improved seed germination
erosion
Fire: complete residue removal
Carbohydrate Management: Carbohydrate Management Carbohydrates (TNC’s) are the products of photosynthesis
Plant part removal and regrowth requires utilization of TNC’s.
Depletion of TNC’s=Plant death
Reproductive organs are sites of TNC’s
Consumption and defoliation deplete Plant TNC
Carbohydrate Management: Carbohydrate Management Consequently vegetation management is Carbohydrate Management
Minimize TNC depletion of target plants
Maximize TNC depletion of weeds
Utilize growth curve knowledge for timing
Keep forage vegetative for browsers/grazers
Keep plant reproductive for seed
Ecology: Ecology Balancing act
What helps one hurts another
Maximize niches
Shelter areas
Water areas
Food areas
Examples: Examples Long strips of Shelter belts surrounded by foraging strips
Checkerboard: alternating squares of forage and shrub/ trees
Islands of shrubs/trees circled by forage
Mixtures of tall and short grass
Mixtures of adjacent mown and unmown plots
Summary: Summary Maximize plant numbers and diversity over time and space by carbohydrate management of the plant
Maximize animal numbers and diversity over time and space by vegetation management
Start with a small number of target plants and animal, increase over time
