Bahia Grass | Plants

Paspalum Notatum • Also known as: Paspalum, Common Paspalum

Available data highlights its utility in regenerative agriculture, primarily as a component of sod-based rotations and perennial forage systems. It has been evaluated as a cover crop in post-mining soil restoration and as a key element in grazed perennial forage-crop rotations (FCR). In Florida experiments, bahiagrass was used in sod-based rotations as an alternative to conventional tillage, preceding cash crops like vegetables. Studies suggest its integration with other perennial legumes, such as rhizoma peanut, can enhance soil microbial diversity. Bahiagrass's role in sod-based systems and rotations suggests contributions to soil building and potentially carbon sequestration, though specific data on these benefits within the provided excerpts is not detailed. Its incorporation into grazed systems and as a component in tillage alternatives points to its integration with regenerative practices like rotational grazing and reduced tillage. While coverage in our knowledge base is limited, the above represents documented uses in regenerative systems.

Regenerative Trait Ratings

How These Traits Are Calculated

Trait dimensions are ordered clockwise starting from the top of the chart (12 o'clock position):

1. Profit Potential

Economic returns from hay sales, grazing value, and system contributions

WHAT: Synthesizes direct revenue potential (hay sales or grazing service value) with system contributions (nitrogen fixation, reduced supplement needs) into net economic value. Captures both cash income and cost savings.

WHY: Forage profitability comes from two sources—direct sales (hay, haylage) or indirect value (grazing services supporting livestock production). High-value forages provide $300-600/acre in combined revenue and savings versus $100-200/acre for lower-value options. This determines whether forage enterprises are viable versus purchasing feed.

HOW: Scored via LLM synthesis of economics data (hay yields, prices, grazing value), timeline considerations (establishment costs, productive lifespan), and system value (nitrogen contributions, supplement replacement). Exceptional (3.0): High yields with premium pricing or exceptional grazing value plus nitrogen fixation. Typical (2.0): Moderate returns. Limited (1.0): Low yields, commodity pricing, or minimal system contributions.

2. Palatability

Livestock preference and voluntary consumption rates

WHAT: Measures how eagerly livestock consume the forage—preference ranking when choices are available. Highly palatable forages are grazed first and completely; limited palatability means animals avoid unless no alternatives exist.

WHY: Palatability directly determines voluntary intake, which drives animal performance. High-palatability forages support faster weight gain and higher milk production because animals eat more. Low-palatability forages reduce performance and waste productive potential—animals selectively graze preferred species and leave unpalatable plants ungrazed.

HOW: Ratings based on the palatability trait documenting livestock selection preference. Exceptional (3.0): Preferentially selected, high sugar content, tender growth eagerly consumed (orchardgrass, white clover, ryegrass). Typical (2.0): Readily consumed when available. Limited (1.0): Avoided unless no other options (coarse stems, bitter compounds, low digestibility).

3. Nutritional Value

Protein content and forage quality for livestock growth and production

WHAT: Measures protein content as the primary indicator of forage nutritional quality. High-protein forages (>18%) support rapid growth and high milk production; low-protein forages (<12%) require supplementation for production animals.

WHY: Protein is the most expensive supplement in livestock diets ($0.40-0.60/lb). Forages with exceptional protein content eliminate or reduce supplement costs while supporting maximum animal performance. High-quality forage can save $200-400/cow/year in purchased feed versus low-protein options.

HOW: Ratings based on the protein_content trait. Exceptional (3.0): High protein (>18%) supporting rapid weight gain or high milk production (alfalfa, clovers, young grasses). Typical (2.0): Moderate protein (12-18%) for maintenance and moderate production (mature grasses). Limited (1.0): Low protein (<12%) requiring supplementation for production animals (mature warm-season grasses, low-fertility forages).

4. Climate Resilience

Weighted: drought tolerance (60%) + climate adaptability (40%)

WHAT: Combines drought tolerance (primary climate stressor for forages) with overall climate adaptability (temperature range, geographic flexibility). Resilient forages survive extended dry periods and diverse weather patterns.

WHY: Drought is the most common forage crisis—dry years can cut production 50-80% and force costly hay purchases or herd reductions. Drought-tolerant forages maintain productivity through dry spells, reducing feed costs and providing grazing when less-resilient options fail. Geographic adaptability allows forage systems to work across farm regions.

HOW: Weighted formula prioritizes drought tolerance (60% weight) as primary stressor, with climate adaptability (40% weight) for temperature and general flexibility. Exceptional (3.0): Survives extended drought (6+ weeks) with minimal production loss and works across diverse climates. Typical (2.0): Moderate drought and climate tolerance. Limited (1.0): Drought-sensitive or narrow climate requirements.

5. Grazing Durability

Weighted: trampling tolerance (70%) + seasonal availability (30%)

WHAT: Combines grazing tolerance (resistance to trampling and frequent defoliation) with seasonal availability (timing and duration of productive growth). Durable forages handle intensive rotational grazing and provide consistent seasonal production.

WHY: Grazing tolerance determines management system viability. Tolerant forages allow intensive rotational grazing or mob grazing for maximum animal performance and pasture health. Intolerant forages are hay-only or require long rest periods. Seasonal availability indicates production timing—year-round, seasonal gaps, or narrow windows.

HOW: Weighted formula prioritizes grazing tolerance (70% weight) for management system determination, with seasonal availability (30% weight) for production timing. Exceptional (3.0): Handles intensive rotational grazing with consistent seasonal production. Typical (2.0): Moderate tolerance and availability. Limited (1.0): Hay-only species or narrow seasonal production windows.

6. Management Ease

Weighted: establishment ease (50%) + low maintenance needs (50%)

WHAT: Combines establishment difficulty (germination, stand establishment) with ongoing maintenance requirements (fertility, weed control, renovation needs). Easy forages establish reliably and persist without intensive management.

WHY: Pasture establishment is expensive ($150-400/acre) and risky. Easy-to-establish forages reduce stand failure risk and provide quicker returns. Low-maintenance forages reduce annual input costs and labor, improving long-term profitability of grazing systems.

HOW: Weighted formula balances establishment ease (50% weight) for startup success and inverted maintenance intensity (50% weight) for ongoing care. Exceptional (3.0): Fast germination, reliable stand establishment, minimal fertility/weed management needs (white clover, orchardgrass). Typical (2.0): Moderate establishment and care requirements. Limited (1.0): Difficult establishment or intensive maintenance (heavy fertility, frequent renovation, weed competition).

7. Multi-Benefit Value

Ecosystem services beyond forage—nitrogen fixation, pollinator support, wildlife habitat

WHAT: Measures ecosystem services provided beyond livestock nutrition. Multi-benefit forages contribute nitrogen fixation (legumes), pollinator support (flowering species), wildlife habitat, soil building, erosion control, and biodiversity support.

WHY: Forage systems can either extract from farm ecosystems or contribute to them. Nitrogen-fixing legumes (clovers, alfalfa) provide $80-150/acre/year worth of fertility for companion grasses and following crops. Flowering forages support pollinators critical for fruit/vegetable crops. These service-stacking forages deliver total system value beyond livestock production.

HOW: Ratings based on the multi_benefit_value trait documenting service diversity. Exceptional (3.0): Multiple significant benefits (legumes fixing 80-150 lbs N/acre/year + pollinator support + wildlife forage). Typical (2.0): Some ecosystem contributions. Limited (1.0): Single-purpose forage with minimal ecosystem services beyond grazing value.

Ratings are based on documented performance in regenerative systems, not conventional high-input scenarios. All traits assume integrated management practices focused on soil health and ecosystem services.

Climate Suitability Assessment

Will this plant thrive in your climate?

IDEALLY SUITED

Köppen Zone: Af (Tropical Rainforest), Am (Tropical Monsoon), Aw (Tropical Savanna), Cfa (Humid Subtropical), Cwa (Monsoon-Influenced Humid Subtropical)
USDA Zone: 7a, 8a, 9a, 10a, 11a, 12a
Australian Zone: tropical, subtropical

Bahia grass performs optimally in regions with long, hot growing seasons and ample rainfall, typically exceeding 40 inches (100 cm) annually. These conditions are met in Köppen zones Cfa, Cwa, Aw, and Am, and in Australian zones subtropical and tropical, as well as USDA zones 8a through 13a. The species thrives in temperatures ranging from 75-90°F (24-32°C), with minimal frost risk. Its deep root system allows it to tolerate short dry spells, but consistent moisture is preferred for maximum productivity. In these ideal climates, Bahia grass establishes readily, forms a dense sod, provides excellent ground cover, and offers high-quality forage. It is well-suited for multi-year use as a cover crop or pasture, requiring minimal management beyond occasional mowing or grazing. Its aggressive growth habit helps suppress weeds and improve soil structure, contributing significantly to regenerative agriculture practices.

ADEQUATE

Köppen Zone: BSh (Hot Semi-Arid (Steppe)), Cfb (Oceanic (Maritime Temperate)), Csa (Hot-Summer Mediterranean), Csb (Warm-Summer Mediterranean), Cwb (Subtropical Highland)
USDA Zone: 6a
Australian Zone: grassland, temperate
EU Climate Region: atlantic

Bahia grass can be grown successfully in regions with adequate growing seasons and moderate rainfall, typically 30-40 inches (75-100 cm) annually, though supplemental irrigation may be necessary during dry periods. These conditions are found in Köppen zone Cwa (in cooler sub-regions), Australian zones grassland and temperate, and EU Atlantic regions, as well as USDA zones 7a and 7b. While it can establish and provide cover, its productivity and stand persistence may be reduced compared to ideal climates. Summer heat is generally sufficient, but cooler temperatures or shorter growing seasons can lead to dormancy. Management may involve more attention to water availability and potentially fertilization to maintain vigor. It remains a viable option for cover cropping and forage, offering benefits in soil health and weed suppression, but requires careful consideration of local microclimates and potential for drought stress.

NOT RECOMMENDED

Köppen Zone: ET (Tundra), BSk (Cold Semi-Arid (Steppe)), BWh (Hot Desert), BWk (Cold Desert), Dfa (Hot-Summer Continental), Dfb (Warm-Summer Continental), Dfc (Subarctic), Dwa (Monsoon-Influenced Hot-Summer Continental)
USDA Zone: 2a, 3a, 3b, 4a, 5a, 5b
Australian Zone: arid
EU Climate Region: mediterranean

Bahia grass is not recommended for climates with prolonged dry seasons or insufficient rainfall (less than 25-30 inches/65-75 cm annually) and extreme temperature fluctuations. This includes Köppen zones Csa and Csb, Australian arid zones, and EU Mediterranean regions, as well as USDA zones below 7a where winter survival is also a concern. The hot, dry summers characteristic of Mediterranean and semi-arid climates severely limit its growth and survival, necessitating extensive and costly irrigation. In cooler maritime climates (Csb), it may struggle to establish and perform due to insufficient heat and competition from cooler-season grasses. Its aggressive nature is not suited for water conservation in arid areas, and its performance is significantly compromised, making it economically unviable for regenerative agriculture without substantial intervention. Alternative species better adapted to drought or specific temperature regimes are strongly advised.

Better alternatives for these "not recommended" zones: Bermuda Grass (Cynodon dactylon) (highly drought-tolerant and heat-loving grass adapted to dry summers), Buffel Grass (Cenchrus ciliaris) (highly drought-tolerant and adapted to arid/semi-arid conditions), Kikuyu Grass (Pennisetum clandestinum) (vigorous, drought-tolerant grass that can handle Mediterranean conditions), Perennial Ryegrass (Lolium perenne) (cool-season grass that thrives in mild, wet climates)

Note: Zones listed above represent climates where this plant can produce reliably with reasonable management. Climate zones not mentioned would require intensive climate modification (greenhouses, extensive infrastructure) and are not economically viable for regenerative agriculture purposes.

Soil Suitability Assessment

Which soil types work best for this plant?

IDEALLY SUITED

Loam Soil

This plant thrives in these soil types without requiring amendments or remediation. Natural soil conditions support optimal growth and productivity.

ADEQUATE

Acidic Soil, Alkaline Soil, Clay Soil, Rich Soil, Rocky Soil, Sandy Soil

This plant performs acceptably in these soil types with moderate, manageable remediation such as pH adjustment, compost addition, or drainage improvement. The required amendments are practical and cost-effective for regenerative agriculture.

NOT RECOMMENDED

Desert Soil, Saline Soil, Wet Soil

Growing this plant in these soil types would require impractical remediation such as complete soil replacement, extensive amendments, or cost-prohibitive infrastructure. These conditions are not economically viable for regenerative agriculture.

Note: Soil suitability assessments focus on remediation requirements. "Ideally Suited" means the plant generally thrives without the need for substantial amendments, "Adequate" means manageable remediation (lime, compost, mulch), and "Not Recommended" means impractical soil changes would be required. Climate factors like rainfall and temperature also influence success.

Seasonal Considerations

Planting timing, growth duration, and harvest windows

Bahia grass thrives in warm conditions, making establishment ideal in early spring, after the last expected frost, when soil temperatures consistently reach 60°F (15°C). Expect good establishment within 4-6 weeks under optimal moisture. Begin rotational grazing once plants have developed a robust root system and are 6-8 inches tall, typically 2-3 months after seeding. Aim for a residual height of 3-4 inches during grazing to promote quick regrowth.

Summer is bahia grass's peak production period, offering excellent biomass for grazing. Allow 3-4 weeks of rest between grazing cycles during this active growth phase. With adequate fertility and moisture, you can expect 2-3 hay cuttings per season, with the first typically taken in mid-summer. As fall progresses and temperatures cool, growth will slow. Bahia grass exhibits good frost tolerance, allowing for some late-season grazing before winter dormancy sets in. It will remain dormant through the coldest months, with regrowth commencing again in early spring.

System Role & Multi-Benefit Value

Functional roles, integration strategies, and stacked benefits

Functional Role

Total System Value

Bahia grass offers substantial whole-farm resilience by acting as a foundational element in soil health regeneration. As a perennial cover crop and forage, it directly contributes to reducing soil erosion and increasing soil organic matter over time, sequestering carbon in the process. Its role in sod-based and forage-crop rotations, as seen in studies comparing it to conventional tillage, highlights its capacity to enhance soil structure and microbial activity, thereby improving water infiltration and retention. When intercropped with legumes, it synergistically boosts nitrogen availability. While direct harvest value might be limited to forage, its primary contribution lies in ecosystem services: improving soil health, potentially supporting wildlife habitat, and enhancing water quality by reducing runoff. In grazed systems, it provides a consistent, resilient forage base for livestock, diversifying farm income streams and reducing risk associated with annual crop failures or market volatility. This perennial cover enhances the overall stability and productivity of the agricultural landscape.

Management & Care Requirements

Integration guidance, maintenance needs, and care practices

How to Integrate This Plant

Bahia grass (Paspalum notatum) can be integrated into regenerative systems primarily as a component of sod-based rotations and perennial forage systems. Its primary function is soil cover and improvement, contributing to erosion control and soil organic matter. It is particularly effective in grazed perennial forage-crop rotations (FCR) and sod-based rotations where it can be managed through grazing or as a preceding crop phase. Bahigrass establishes relatively quickly, providing ground cover within the first year. Its perennial nature means it builds soil health over time, with significant benefits to soil structure and carbon sequestration becoming more apparent by year 3-5. The system value extends beyond direct harvest (if any) to enhancing soil biology, suppressing weeds, and creating a more resilient farming system by reducing reliance on annual tillage. It can also be intercropped with legumes like rhizoma peanut to boost nitrogen fixation and further enhance soil biodiversity, contributing to a multi-benefit stacking approach in farm design.

Integration Practices & Management

The provided knowledge base offers limited direct insights into the specific methods regenerative farmers use to integrate Paspalum notatum. However, it does indicate its use in sod-based rotations and grazed perennial forage-crop rotations within the Southern Coastal Plain of the United States and southern Brazil. Source mentions its use in three or four-year sod rotations preceding vegetable cash crops, implying a role in building soil health prior to annual crop production. Source discusses bahiagrass in a grazed perennial forage-crop rotation system, alongside cattle grazing, suggesting integration with livestock. While the knowledge base doesn't detail establishment techniques like seeding rates or timing, nor specific grazing management like mob grazing or rest periods, it highlights its function as a long-term perennial component in systems designed to improve soil conditions. Termination strategies and detailed fertility or competition management practices are not elaborated upon within these sources. The primary takeaway is Paspalum notatum's established role as a foundational perennial in established rotation systems, particularly in humid subtropical agricultural regions, serving as a precursor or component in crop and livestock integration.

System Enhancement Value

Beyond cost recovery: soil building, nitrogen, biomass, and weed suppression

Soil Building & Weed Suppression

Bahiagrass, as a perennial forage crop, significantly contributes to soil health improvement when integrated into cropping systems. Knowledge base excerpt highlights its use in sod-based rotations for organic vegetable production, where it precedes cash crops like bush beans, soybeans, and broccoli. This perennial phase effectively builds soil organic matter and improves soil structure over several years of establishment. Excerpt further supports this by evaluating bahiagrass in a grazed perennial forage-crop rotation (FCR) system, where it has the potential to increase Soil Organic Carbon (SOC) storage, particularly when managed with conservation tillage. The study also noted that moderate grazing did not negatively impact SOC storage or soil GHG emissions in FCR systems, suggesting bahiagrass can be a resilient component of integrated livestock-crop operations.

Erosion Control

While bahiagrass is primarily known for its ground cover and forage potential, its dense root system and upright growth habit can contribute to soil stabilization and erosion control, which indirectly supports windbreak functions by preventing soil loss that could otherwise be mobilized by wind. In systems where it's used in rotation, the establishment of a robust sod like bahiagrass prior to cash crops can improve soil structure, leading to better water infiltration and reduced susceptibility to wind erosion in subsequent years. However, it is not typically planted in dedicated windbreak rows or as a primary windbreak species.

Ecosystem Service Contributions

Environmental contributions: carbon, pollinators, wildlife, and water

Carbon Sequestration: Bahiagrass has a dense root system that can contribute to soil organic carbon (SOC) sequestration, especially when managed as part of a perennial forage-crop rotation or sod-based system, as indicated by excerpt and. The extent of sequestration is influenced by management practices and soil conditions.
Pollinator Support: Low. While bahiagrass does flower, its primary role is not as a significant nectar or pollen source for commercially important pollinators. Its dense growth can outcompete many flowering forbs that would otherwise support pollinators.
Wildlife Habitat: Provides ground cover and nesting habitat for small ground-dwelling animals and ground-nesting birds. Its biomass can offer some browse for certain herbivores, though it is generally considered a less palatable forage for livestock compared to other grasses.
Water Quality: Not applicable

Farm Risk Reduction

How this reduces farm risk: lower input costs and better soil resilience

Multiple Revenue Streams: Forage for livestock, soil health improvement (leading to reduced input costs and increased resilience for cash crops), potential for biomass production, and reduced erosion risk.
Temporal Income Spread: Provides ongoing ecosystem services and soil building benefits throughout its perennial stand, while also serving as a foundation for sequenced cash crop harvests. It offers a stable base that buffers the volatility of annual crop markets.
Market Risk Hedge: Diversifies farm revenue by providing a forage option that can be sold or utilized internally. Its role in improving soil health acts as a natural hedge against rising input costs (fertilizers, pesticides) and the impacts of climate variability (drought, heavy rainfall) on cash crop yields. Excerpt notes that sod-based rotations with bahiagrass can lead to lower risk and higher profitability in organic vegetable production.

Why farmers use this plant and additional resources

Why Regenerative Farmers Use This Plant

Paspalum notatum, commonly known as Bahia grass, is a highly resilient and persistent perennial grass that offers significant regenerative benefits in livestock systems. Its robust, dense, and fibrous root system, which can reach depths of 3-6 feet (0.9-1.8 meters), excels at improving soil structure, enhancing water infiltration (rates can be 2-3 times higher than compacted soils), and reducing erosion, particularly in areas prone to heavy rainfall, drought, or on sloped or sandy soils. This deep rooting also contributes to significant carbon sequestration, with established stands capable of building substantial soil organic matter over time and storing carbon in the soil profile.

Bahia grass is well-suited for grazing and can support a respectable carrying capacity, typically ranging from 1.5 to 3 Animal Units per acre (3.7 to 7.4 AU/ha) under well-managed rotational grazing systems, depending on soil fertility and rainfall. Its forage quality is moderate, with crude protein levels generally between 8-14% during the vegetative stage, declining to 7-9% in stockpiled mature growth. It provides good levels of Total Digestible Nutrients (TDN), contributing to steady livestock weight gain and milk production.

Beyond its soil-building capabilities, Paspalum notatum integrates seamlessly into pasture renovation and maintenance. It is exceptionally drought-tolerant once established, making it a valuable forage in regions with unreliable rainfall. Its ability to spread via rhizomes and stolons allows it to effectively cover bare ground, suppressing weeds and providing continuous ground cover throughout the growing season. This persistence means less need for reseeding and reduced soil disturbance compared to annual forages. While not a legume, its dense sod can improve nutrient cycling by holding onto available nutrients and making them accessible to subsequent crops or grazing cycles, and it efficiently scavenges nutrients from lower soil profiles, reducing reliance on external fertilizer inputs.

The ecological contributions of Paspalum notatum extend to supporting biodiversity. Its dense growth provides habitat for beneficial insects and ground-nesting birds. As a warm-season grass, it offers high-quality forage during the summer months, helping to fill seasonal gaps when cool-season grasses may be less productive or dormant. This can extend the grazing season by 30-60 days in suitable climates, reducing reliance on supplemental feed and positively impacting livestock weight gain and milk production during peak growth periods. Its palatability is generally good for cattle and horses, though it can be less preferred by sheep and goats.

Bahia grass has a proven track record in various agricultural landscapes. In the southeastern United States, it is a cornerstone of cattle ranching, providing reliable summer grazing and supporting high stocking rates on marginal lands. In Australia, it is used in pastures across the subtropical regions for cattle grazing and erosion control on sandy soils. In South America, particularly in Brazil and Argentina, it is valued for its drought tolerance and ability to thrive on less fertile and acidic soils, contributing to the sustainability of extensive cattle operations and serving as a cover crop in coffee and citrus plantations to prevent soil erosion and improve soil health. Its adaptability to a range of soil types, from sandy to clay, further enhances its utility in diverse farming systems.

How to Integrate This Plant

Practical guidance for regenerative systems

Establishing Paspalum notatum typically involves seeding. For broadcast seeding, rates vary from 20-40 lbs/acre (22-45 kg/ha) for common types and 10-20 lbs/acre (11-22 kg/ha) for improved varieties. Drilled seed rates can be slightly lower, around 15-30 lbs/acre (17-34 kg/ha). The optimal planting depth is shallow, between 0.25-0.5 inches (0.6-1.3 cm), to ensure good seed-to-soil contact, as the seeds require light for germination. For best results, planting should occur in late spring or early summer when soil temperatures are consistently warm, ideally above 15°C (60°F) or 18°C (65°F). In the Northern Hemisphere, this typically means planting from April to June, while in the Southern Hemisphere, planting occurs from October to December. Seedbed preparation should aim for a firm, weed-free surface. Establishment can take 60-90 days to achieve good ground cover, with full stand development taking up to two growing seasons to reach full productivity and density.

Once established, Paspalum notatum requires moderate management for optimal performance. It generally needs about 1 inch (2.5 cm) of rainfall or irrigation per week during its active growth period. While it can tolerate low fertility and acidic soils, incorporating compost, well-composted manure, or utilizing residue from rotational grazing will significantly enhance its productivity and forage quality. Its growth rate is steady during the warm season, reaching maturity and a height of 2-4 feet (0.6-1.2 meters) within 60-90 days after emergence. Pest and disease pressure is generally low, with its resilience and dense growth habit providing natural resistance. If issues arise, focusing on maintaining plant health through proper grazing and fertility management is the primary regenerative approach.

In terms of grazing management and livestock integration, Paspalum notatum is best managed with rotational grazing to maximize forage utilization and plant health. It can typically support 1.5-3 Animal Units per acre (3.7-7.4 AU/ha) under well-managed rotational systems. Grazing should commence when the grass reaches approximately 8-12 inches (20-30 cm) in height, and animals should be removed when the residual height is around 3-4 inches (8-10 cm). This practice encourages tillering and rapid regrowth. Rest periods of 30-45 days are crucial during the active growing season to allow for adequate recovery. Under adaptive multi-paddock grazing, cattle moved onto the stand at 8-12 inches (20-30 cm) and pulled at 3-4 inch (8-10 cm) residual height can gain 1.0-1.8 lbs/day (0.45-0.8 kg/day) during peak growth. Fall stockpiling of mature growth can provide grazing into the cooler months, extending the season by 30-60 days in suitable climates, with crude protein levels in stockpiled forage typically ranging from 7-9%. This stockpiled growth can maintain crude protein above 10% through early winter in USDA Zones 7-9, reducing hay feeding costs by 20-40%. Bahiagrass is highly palatable to cattle and sheep, though goats may browse it selectively.
