Targeted grazing: a natural approach to vegetation management and landscape enhancement SUSAN SCHOENIAN (Shāy-nē-ŭn) Extension Sheep & Goat Specialist Western Maryland Research & Education Centersschoen@umd.edu - www.sheepandgoat.com
GrazingTo feed on herbage in a field  Grazing by wild and domestic animals is natural. Along with fire, grazing is the oldest vegetative management tool. Grazing changes plant communities.
Two “general” kinds of grazing Uncontrolled No management Animals eat what they want; leave what they don’t want. Animals graze for as long as they want. They go where they want. Controlled Land is usually sub-divided into smaller paddocks for grazing. The type and number of animals that are allowed to graze is controlled. The length of the grazing period is managed. Pastures are rested before animals are allowed to graze re-growth. Fragile areas are fenced off.
Impacts of uncontrolled grazing Can result in overgrazing if stocking densities are too high, grazing duration is too long, and/or grazing frequency is too often. Favors undesirable plant species (e.g. invasives, noxious weeds, toxic plants). Can be destructive to the environment: erosion, deforestation, desertification, etc.
Benefits of controlled grazing Eliminates potential negative impacts of grazing on the environment.Negative -> positive Impact Improves efficiency of forage utilization. Usually returns more dollars to the producer’s pocket.
Environmental benefitsWell-managed pasture + good grazing practices  Reduce soil erosion Nutrient recycling Improve soil quality Reduce run-off Improve air and water quality. Better plant diversity, vigor, and production. Improved fish and wildlife habitat
Weeds - unwanted plants Grass Conifer Browse Forb There are many unwanted plants in our landscapes. How do we get rid of them?

Targeted grazing Also called prescribed grazing “The application of a specific kind of livestock at a determined season, duration, and intensity, to accomplish defined vegetation or landscape goals.”(Launchbaugh and Walker 2006) Goat grazing bog turtle habitat in Maryland.
Pros and cons of targeted grazing PROS Cost More environmentally-friendly. Eliminate risks of other methods: dust, safety, chemicals. Livestock do not cut grass and weeds down to ground level. Socially-acceptable Natural Green image CONS Cost Rules against livestock Predator risk Animal health risk Droppings in urban areas
Challenge Demand exceeds supply. There seems to be more of a demand for grazing services than there is service providers. www.eco-goats.com www.livestockforlandscapes.com
Knowledge of animals and plants is essential for targeted grazing plants animals

Understanding grazing behavior Goats ,[object Object]
Most selective grazer.
Most tolerant of secondary plant compounds.Cattle Prefer grasses. Less selective. Graze more uniformly. Least tolerant of secondary plant compounds. Sheep Prefer forbs, then grasses. Selective grazer. Tolerant of secondary plant compounds.
Small ruminants vs. cattle Sheep and goats ,[object Object]
Prefer to graze and bed on upland areas and away from wet lowlands.
Can graze steep, rocky areas.
Their smaller hooves have less of an impact.
Require better fencing
Predator riskCattle  Consume a more homogenous diet. Prefer lowlands for grazing Their bigger hooves have more of an impact (e.g. soil compaction).
Sheep vs. goats Sheep goats Grass and forb-dominated landscapes Orchards Vineyards Young tree plantations Christmas tree farms Around solar panels Heavy brush Woody plants Shrubs Trees Select most diverse diet High browse line Before and after shot at the 2009 Western Maryland  Pasture-Based Meat Goat Performance Test.
What kind of sheep or goat? Breed (size) Bigger breeds can graze or browse higher. Some breeds are hardier (more disease-resistant). Age Older animals are more likely to eat different plants. Young animals have to “learn” what to eat. Sex Females and wethers are easier to manage than intact males. Physiological condition Young, growing animals and pregnant or lactating females have higher nutritional requirements that may not be met on the job site.
