Florida faces a critical challenge in wetland management as invasive species threaten ecosystem integrity across the state. The South Florida Water Management District identifies approximately 200 introduced plant and animal species established in the region, with 66 non-native plant species designated as priorities for control. Current management strategies rely heavily on mechanical removal, prescribed burns, and herbicide applications—methods that are expensive, labor-intensive, and may have unintended ecological consequences.
Simultaneously, livestock grazing in wetland environments remains controversial and understudied, particularly in subtropical climates. While extensive research documents livestock impacts on wetlands, the vast majority focuses on cattle in temperate regions. Research on sheep grazing in subtropical wetlands, specifically using parasite-resistant hair sheep breeds, remains critically limited.

Katahdin sheep represent a unique opportunity for Florida wetland management due to their specific biological adaptations:
Parasite Resistance: Research demonstrates that Katahdin sheep possess significantly higher parasite resistance than conventional wool breeds. Studies conducted at Virginia Tech and Arkansas showed Katahdin sheep had fecal egg counts 45% lower than Dorper crosses and required substantially less anthelmintic treatment than wool breeds. Their Caribbean hair sheep ancestry provides genetic resistance evolved in hot, humid, high-parasite environments—precisely the conditions present in Florida wetlands.
Climate Adaptation: Katahdin sheep demonstrate well-developed heat tolerance in tropical and subtropical regions. Their hair coat (rather than wool) allows superior thermoregulation in humid conditions where wool breeds experience heat stress. University of Florida research identifies Katahdin as one of six meat breeds demonstrating ability to naturally minimize parasite burdens in Florida conditions.
Selective Grazing Behavior: Sheep exhibit different grazing patterns than cattle. Research indicates sheep nibble grass close to the ground and selectively consume flowers and certain vegetation types. This selective grazing could target specific invasive plant species while minimizing impact on desired native vegetation.
Reduced Wetland Impact: Sheep are lighter and more agile than cattle, causing less soil compaction and trampling damage. Studies in New Zealand and British Columbia specifically noted that sheep grazing can be preferable to cattle in fragile wetland environments vulnerable to poaching (soil damage from hoofprints in wet conditions).
Vegetation Management Without Chemicals: Multiple studies demonstrate that moderate grazing intensity can increase plant species diversity and control dominant invasive species that exclude less competitive native plants. Research in California vernal pools showed that reintroduced grazing at moderate stocking rates significantly increased both diversity and native cover after just two years. European wetland studies found that patchy, occasionally intense grazing increased protected plant species and habitat heterogeneity while benefiting both conservation and agricultural goals.
Cost-Effective Management: The solar grazing industry demonstrates that sheep can provide effective, economical vegetation management. While mechanical mowing requires expensive equipment, fuel, and risks panel/infrastructure damage, sheep provide continuous low-cost maintenance while generating potential revenue through meat production.
Ecosystem Services: Properly managed grazing can create habitat heterogeneity that benefits wildlife. Research in Hungarian marshes showed increases in wetland bird populations, protected plant species, and patches of open vegetation with grazing intensity gradients. The key is avoiding continuous heavy grazing while allowing patchy, varied grazing pressure.
Carbon Footprint Reduction: Replacing mechanical vegetation management eliminates fossil fuel consumption for mowers while integrating livestock production into ecosystem restoration.
Hypothesis: Katahdin sheep grazing at moderate stocking densities (2-4 sheep/acre for 2-4 week periods) will significantly reduce biomass of target invasive species compared to ungrazed control areas, while maintaining or increasing native plant species diversity.
Hypothesis: Moderate-intensity sheep grazing will maintain water quality parameters (turbidity, nitrogen, phosphorus, fecal coliform bacteria) within acceptable ranges for wetland ecosystem health, with impacts significantly lower than documented cattle grazing effects.
Hypothesis: Katahdin sheep grazing on Florida wetland vegetation will maintain adequate body condition scores and parasite resistance within acceptable management thresholds, requiring no more than 15% of animals to need anthelmintic treatment during the grazing period.
Hypothesis: Sheep grazing vegetation management costs will be ≤50% of equivalent mechanical mowing and herbicide application costs over a 12-month period, while producing marketable lamb weight gain.

There's a moment — and if you've ever watched a child meet a lamb for the very first time, you know exactly what I'm talking about — where learning stops being something that happens to a kid and starts being something that happens in them.
That moment doesn't usually happen in a classroom. It happens outside, in the open air, with muddy boots and wide eyes and a question they didn't even know they had until the animal was right in front of them.
This March 14th, Black Hammock Farm is hosting exactly that kind of moment — and every family in Central Florida should know about it.
Functional Farm Science: The Lifecycle of the Lamb isn't a passive field trip. It's a structured, hands-on farm lab experience co-created by Tyler Lacertosa, OTD, and Dr. Melissa Mesman (EdD candidate) through CommunOT Farm & Programming — a pediatric occupational therapy organization rooted in Seminole County, FL.
The premise is simple but powerful: real science education happens best in real environments. And right now, during lambing season on a working heritage livestock farm, there is no better classroom on earth than Black Hammock Farm in Oviedo, Florida.
This is hands-on farm science education in Florida at its finest — built for children ages 2–18, including learners with sensory processing needs.
When students arrive at Black Hammock Farm, they won't be handed a worksheet and told to observe. They'll be participants — guided through the same assessment practices that professional shepherds and veterinary staff use every day.
Here's what the farm lab includes:
Students use their hands to evaluate the health and nutritional status of sheep through a standardized palpation technique — no scales, no equipment, just trained observation. This is nature-based occupational therapy farm experience in action: sensory engagement that builds both scientific understanding and real-world skill.
Participants explore the CDT vaccination schedule — what it protects against, why timing matters, and why a lamb's first hours of life are critical for immunity. Age-differentiated materials ensure every learner, from toddler to teen, connects with the content meaningfully.
Students interact directly with Katahdin sheep and their lambs in an open pasture setting, then use printed field guides to record and document their observations — building the habits of scientific inquiry through structured discovery.
This is the kind of outdoor science lab for kids in Seminole County, FL that turns a Saturday morning into a memory that shapes how a child thinks about the natural world for years to come.
Not every farm can host an experience like this. Black Hammock Farm isn't just a venue — it's a working heritage livestock operation raising Katahdin sheep and free-range poultry with a deep commitment to ethical, educational animal husbandry.
Katahdin sheep are a hair breed known for their gentle temperament and ease of management — which makes them especially well-suited to educational interaction with children. And March, right in the heart of lambing season, is the most powerful time of year to explore the livestock lifecycle firsthand.
The open-air farm environment also does something a classroom simply can't: it provides the sensory regulation inputs — natural textures, gentle animal sounds, fresh air, unstructured outdoor movement — that help children with sensory processing needs regulate and focus.

One of the things that makes this hands-on livestock science field trip in Central Florida so special is that it was designed with every learner in mind — not just neurotypical students, not just older kids, not just homeschoolers.
CommunOT has developed age-differentiated take-home materials for this event:
Younger participants receive warmly illustrated content with accessible vocabulary
Teen participants receive rigorous packets with scientific terminology, scenario analysis, and OT-connected reflection prompts
Parents receive their own guidance on how to support their child's engagement and extend the learning at home
Whether your child is two or eighteen, there's a meaningful entry point waiting for them at Black Hammock Farm.
The March 14th event is the first of two planned CommunOT farm programming sessions for 2026. The fall event, Harvest & Thrive, will build on the themes introduced this spring. Families who participate in both gain a longitudinal view of the farm calendar — and a richer understanding of the seasonal rhythms that shape agricultural life.
Farm science education in Florida doesn't have to end when the field trip bus pulls away. At Black Hammock Farm, it's a living, growing curriculum — one that follows the seasons, the animals, and the curiosity of the children who show up ready to learn.
Space is limited. This is a small-group, hands-on experience — not a large open event — which means once it fills up, it fills up.
