# Cervid Pasture Rotation and Stocking Density: Species-Specific Guidelines ## Key Takeaways - **Species-Specific Rotational Grazing is Paramount:** Deer, elk, and bison exhibit distinct grazing behaviors, nutritional needs, and social structures, necessitating tailored paddock sizes (deer: 0.5-2.0 ha; elk: 1.0-4.0 ha; bison: 2.0-10.0 ha), rest periods (deer: 21-30 days; elk: 25-35 days; bison: 30-45 days), and stocking densities (deer: 10-25/ha; elk: 5-15/ha; bison: 2-8/ha) to optimize pasture health and animal performance. - **Fencing and Infrastructure Must Match Species:** Robust fencing is critical, with deer requiring 2.0-2.5m high fences, elk needing 2.0m tall and strong barriers, and bison demanding very strong 2.0-2.5m fences with heavy-gauge wire or pipe to prevent escape and injury. Water access in each paddock or a central lane system is essential. - **Monitoring and Adjustment Drive Success:** Continuous monitoring of grass height (grazing between 15-25 cm down to 5-10 cm) and animal body condition scores is crucial for adjusting grazing periods (1-3 days typical) and rest periods based on seasonal growth rates, climate variations (e.g., extending rest by 50-100% during drought), and observed pasture recovery. - **Common Failure Patterns Require Proactive Management:** Overgrazing due to insufficient rest, selective grazing leading to patchy pasture use, soil compaction and wallow damage (especially with bison), and parasite build-up necessitate extended rest periods (30-45 days), higher stocking densities for shorter durations, and careful management of wet conditions. - **Nutritional Deficiencies and Biosecurity Demand Attention:** Pasture alone may not meet specific mineral requirements (e.g., copper deficiency in red deer causing skeletal abnormalities), requiring supplementation and soil testing; robust biosecurity protocols, including quarantine and disinfection, are vital to prevent disease transmission through shared infrastructure. --- Rotational grazing design, paddock size, rest periods, and stocking density must be tailored to the specific cervid species under management. Deer, elk, and bison differ in grazing behavior, nutritional requirements, social structure, and impact on pasture plants and soil. This article provides species-specific guidelines for cervid pasture rotation and stocking density, drawing on official sources and peer-reviewed research to support practical farm management decisions. ## At a Glance: Cervid Pasture Rotation and Stocking Density The table below summarizes key rotational grazing parameters for farmed deer, elk, and bison. These values are starting points that must be adjusted based on local climate, pasture condition, animal class, and observed performance. | Species | Typical Paddock Size (hectares per group) | Minimum Rest Period (days) | Stocking Density (animals per hectare) | Key Grazing Behavior | |---------|-------------------------------------------|----------------------------|----------------------------------------|----------------------| | Deer (red deer, fallow deer) | 0.5 to 2.0 | 21 to 30 | 10 to 25 (adult hinds) | Selective grazers, prefer forbs and legumes, avoid rank grass | | Elk (wapiti) | 1.0 to 4.0 | 25 to 35 | 5 to 15 (adult cows) | Bulk grazers, consume large volumes of grass, trample more than deer | | Bison | 2.0 to 10.0 | 30 to 45 | 2 to 8 (adult cows) | Heavy grazers, use wallows and rub trees, create patchy disturbance | These parameters are derived from general principles of cervid management and must be validated with on-farm records. The USDA Animal and Plant Health Inspection Service provides resources on cervid health and management at [www.aphis.usda.gov/livestock-poultry-disease/cervid](https://www.aphis.usda.gov/livestock-poultry-disease/cervid). The Food and Agriculture Organization of the United Nations offers guidance on animal genetic resources and production systems at [www.fao.org/dad-is](https://www.fao.org/dad-is) and [www.fao.org/animal-production/en](https://www.fao.org/animal-production/en). ## Rotational Grazing Design Principles for Cervids Rotational grazing involves moving animals between paddocks to allow forage recovery, control parasite burdens, and maintain pasture quality. For cervids, the design must account for species-specific grazing behavior, social dynamics, and environmental impact. ### Paddock Size and Layout Paddock size should match the group size and the desired grazing period. For deer, smaller paddocks (0.5 to 2.0 hectares) work well because deer are selective grazers that move frequently. Elk require larger paddocks (1.0 to 4.0 hectares) to accommodate their bulk grazing habit and social structure. Bison need the largest paddocks (2.0 to 10.0 hectares) to allow for their natural movement patterns and to distribute grazing pressure. Paddock shape influences grazing uniformity. Long, narrow paddocks encourage animals to graze the entire area. Square or irregular paddocks may lead to patchy use, especially in corners where animals congregate. Water access should be available in each paddock or in a central lane system. ### Fencing Considerations Fencing must be species-appropriate. Deer require high fences (2.0 to 2.5 meters) to prevent jumping. Elk need fences at least 2.0 meters tall with sufficient strength to resist leaning. Bison require very strong fences (2.0 to 2.5 meters) with heavy-gauge wire or pipe to contain their strength and tendency to push against barriers. The USDA National Agricultural Library provides resources on animal health and welfare that include fencing considerations at [www.nal.usda.gov/animal-health-and-welfare](https://www.nal.usda.gov/animal-health-and-welfare). ### Grazing Period The grazing period in each paddock should be short enough to prevent regrazing of new shoots. For cervids, a grazing period of 1 to 3 days is typical during active growth. During slower growth, the period may extend to 5 to 7 days. The goal is to remove animals before they graze regrowth, which stresses plants and reduces future yield. ## Rest Period Requirements for Cervid Pastures Rest period is the time between grazing events that allows forage to recover. The required rest period depends on plant growth rate, which is influenced by species, season, soil moisture, and temperature. ### Rest Period by Species Deer pastures generally require 21 to 30 days of rest during the growing season. Deer are selective grazers that leave patches of ungrazed forage, which can become rank and unpalatable if rest is too long. Shorter rest periods (21 days) work well in high-fertility pastures with fast-growing species. Elk pastures need 25 to 35 days of rest. Elk consume more grass per animal and trample more forage than deer. Longer rest allows grass to recover from both grazing and physical damage. In dry conditions, rest may need to extend to 40 days. Bison pastures require the longest rest periods, 30 to 45 days. Bison graze heavily and create wallows and rub areas that disturb soil and vegetation. Extended rest allows plants to recover from this disturbance. Research on large herbivore management in the Northern Great Plains, published in Natural Areas Journal, discusses how grazing strategies affect rangeland health metrics [https://doi.org/10.3375/043.040.0324](https://doi.org/10.3375/043.040.0324). ### Adjusting Rest Periods Rest periods must be adjusted based on pasture condition. Measure grass height before and after grazing. A good rule is to graze when grass reaches 15 to 25 centimeters and remove animals when it is grazed to 5 to 10 centimeters. Rest until grass regrows to the pre-grazing height. During drought, extend rest periods by 50 to 100 percent. During rapid spring growth, shorten rest periods to prevent grass from becoming too mature and losing quality. The USDA Agricultural Research Service provides information on animal production and protection that includes pasture management research at [www.ars.usda.gov/animal-production-and-protection](https://www.ars.usda.gov/animal-production-and-protection). ## Stocking Density Guidelines for Deer, Elk, and Bison Stocking density is the number of animals per unit area at a given time. It differs from stocking rate, which is the number of animals per unit area over the entire grazing season. High stocking density in rotational grazing concentrates animals for short periods, which can improve grazing uniformity and manure distribution. ### Deer Stocking Density For adult red deer hinds, a typical stocking density is 10 to 25 animals per hectare during the grazing period. Lower densities (10 to 15 per hectare) work well on lower-quality pasture or during dry conditions. Higher densities (20 to 25 per hectare) are possible on high-quality, irrigated pasture. Fallow deer can be stocked at slightly higher densities, 15 to 30 animals per hectare, because they are smaller and have lower per-animal forage demand. Stags and young stock may require different densities based on their growth stage and social behavior. ### Elk Stocking Density Elk cows can be stocked at 5 to 15 animals per hectare. Lower densities (5 to 8 per hectare) are appropriate for large cows on moderate-quality pasture. Higher densities (10 to 15 per hectare) work on high-quality pasture with fast regrowth. Elk bulls require lower densities, 3 to 8 animals per hectare, because they are larger and more aggressive during the rut. Overcrowding bulls can lead to injury and stress. ### Bison Stocking Density Bison cows can be stocked at 2 to 8 animals per hectare. Lower densities (2 to 4 per hectare) are needed on native rangeland or low-productivity pasture. Higher densities (5 to 8 per hectare) are possible on improved pasture with irrigation. Bison bulls require the lowest densities, 1 to 4 animals per hectare, due to their large size and social dynamics. Research on pasture-finishing of bison, published in Journal of Animal Science and Biotechnology, indicates that grazing management affects animal metabolic health and meat quality [https://doi.org/10.1186/s40104-023-00843-2](https://doi.org/10.1186/s40104-023-00843-2). ## Practical Implementation Steps for Cervid Rotational Grazing Implementing a rotational grazing system for cervids requires planning, infrastructure, and monitoring. Follow these steps to establish or improve your system. ### Step 1: Assess Your Land and Herd Map your pasture area and divide it into paddocks based on the species-specific guidelines above. Consider soil type, slope, water availability, and existing fences. Count your animals by class (adult females, males, young stock) and calculate total forage demand. ### Step 2: Design Paddock Layout Create paddocks that are accessible from a central lane or gate system. Ensure each paddock has a water source. For deer, include shelter belts or brush piles for hiding. For elk and bison, provide shade structures or natural cover. ### Step 3: Set Initial Grazing and Rest Periods Start with the recommended grazing period (1 to 3 days) and rest period (21 to 45 days depending on species). Adjust based on grass height measurements. Keep records of grazing dates, grass height, and animal condition. ### Step 4: Monitor Forage and Animal Performance Measure grass height before and after grazing. Assess body condition score of animals monthly. Watch for signs of overgrazing, such as bare soil, weed invasion, or reduced regrowth. Watch for undergrazing, such as rank grass or selective grazing patches. ### Step 5: Adjust Based on Season and Conditions Extend rest periods during drought or slow growth. Shorten rest periods during rapid spring growth. Reduce stocking density if animals lose condition or pasture recovery slows. Increase stocking density if pasture is underutilized. ## Records and Measurements for [Cervid Pasture Management](/knowledge/animal-farming/alternative-livestock/cervid-pasture-forage-management-grazing-systems-species-selection) Keeping accurate records allows you to track pasture performance, animal health, and economic outcomes. The following measurements are essential for cervid rotational grazing. ### Forage Measurements Measure grass height at 10 to 20 locations per paddock before and after grazing. Record the average height and the range. Estimate forage mass using a rising plate meter or by clipping and weighing samples. Record the date, paddock number, and animal group. ### Animal Performance Records Record body condition score for a sample of animals each month. Use a 1 to 5 scale for deer and elk, and a 1 to 9 scale for bison. Record live weight if scales are available. Track pregnancy rates, calf survival, and weaning weights. These records help you adjust stocking density and grazing periods. ### Pasture Condition Records Record the percentage of bare soil, weed cover, and desirable forage species in each paddock. Take photos from fixed points each season. Note any erosion, compaction, or wallow damage. These records help you identify paddocks that need longer rest or lower stocking density. ### Grazing Schedule Records Maintain a calendar or spreadsheet showing which paddock each group grazes on each date. Record the number of animals, grazing period, rest period, and any observations. This schedule helps you plan rotations and avoid overgrazing. ## Common Failure Patterns in Cervid Rotational Grazing Several common problems reduce the effectiveness of rotational grazing for cervids. Recognizing these patterns early allows you to make corrections. ### Overgrazing and Under-Resting The most common failure is grazing paddocks too frequently or for too long. Signs include grass grazed below 5 centimeters, bare soil patches, weed invasion, and reduced regrowth. Solution: extend rest periods by 7 to 14 days and reduce grazing period to 1 to 2 days. ### Selective Grazing and Patch Use Cervids, especially deer, are selective grazers that may avoid certain areas or plant species. This leads to patches of rank, ungrazed grass and patches of overgrazed, preferred plants. Solution: use higher stocking density for shorter periods to force more uniform grazing. Mow or harrow paddocks after grazing to distribute manure and reduce patchiness. ### Soil Compaction and Wallow Damage Bison and, to a lesser extent, elk can cause soil compaction and wallow damage, especially in wet conditions. Signs include pugging, bare soil, and reduced infiltration. Solution: avoid grazing when soil is wet. Use sacrifice paddocks or feeding areas during wet periods. Rest damaged paddocks for 60 to 90 days. ### Parasite Build-Up Rotational grazing can reduce parasite burdens, but if rest periods are too short or paddocks are too small, parasites may accumulate. Research on parasite transmission in red deer under pastoral farming conditions, published in Preventive [Veterinary Medicine](/blog/careers/veterinary-medicine-careers-from-clinical-practice-to-public-health), models how grazing management affects paratuberculosis dynamics [https://pubmed.ncbi.nlm.nih.gov/22480407](https://pubmed.ncbi.nlm.nih.gov/22480407). Signs of parasite problems include weight loss, diarrhea, and poor coat condition. Solution: extend rest periods to 30 to 45 days. Use fecal egg counts to monitor parasite levels. ### Nutritional Deficiencies Cervids have specific mineral requirements that may not be met by pasture alone. Research on copper deficiency in farmed red deer, published in New Zealand Veterinary Journal, describes skeletal abnormalities and ataxia associated with low copper levels [https://pubmed.ncbi.nlm.nih.gov/16031812](https://pubmed.ncbi.nlm.nih.gov/16031812). Signs of deficiency include poor growth, bone deformities, and neurological problems. Solution: provide mineral supplements and test pasture and soil mineral levels. ## Welfare and Safety Context for Cervid Grazing Management Rotational grazing affects animal welfare and worker safety. Proper design and management reduce stress and injury. ### Welfare Considerations Cervids are prey animals that require secure, low-stress environments. Paddocks should provide cover for hiding and escape. Avoid sudden changes in group composition or paddock location. Provide clean water and shade in each paddock. Monitor body condition regularly. Animals that lose condition may need lower stocking density, longer rest, or supplemental feed. Animals that become too fat may need higher stocking density or shorter rest. ### Worker Safety Cervids can be dangerous, especially during the rut or when handling. Design paddocks with safe handling facilities, including raceways, crowding pens, and loading ramps. Use escape routes and solid barriers. Train workers in cervid behavior and safe handling techniques. The U.S. Food and Drug Administration provides resources on animal and veterinary topics, including safe handling and drug use, at [www.fda.gov/animal-veterinary](https://www.fda.gov/animal-veterinary). ### Biosecurity Rotational grazing can reduce disease transmission by moving animals away from contaminated areas. However, shared fences, water sources, and handling facilities can spread disease. Implement biosecurity protocols, including cleaning and disinfection of equipment, quarantine of new animals, and separation of different species or age groups. The USDA Animal and Plant Health Inspection Service provides information on cervid health and disease management at [www.aphis.usda.gov/livestock-poultry-disease/cervid](https://www.aphis.usda.gov/livestock-poultry-disease/cervid). ## Limitations and Professional Escalation Criteria Rotational grazing is not suitable for all situations. Recognize the limitations of this system and know when to seek professional advice. ### Limitations Rotational grazing requires more fencing, water infrastructure, and labor than continuous grazing. It may not be cost-effective for small herds or low-value pasture. It may not work well on steep, rocky, or wet terrain where paddock division is difficult. Rotational grazing does not eliminate the need for supplemental feed during drought, winter, or periods of low pasture quality. It does not prevent all parasite problems or nutritional deficiencies. ### Professional Escalation Criteria Consult a veterinarian, animal nutritionist, or pasture specialist if you observe any of the following: - Animals losing condition despite adequate pasture - High parasite burdens that do not respond to grazing management - Nutritional deficiencies confirmed by blood or tissue tests - Soil fertility problems that limit pasture growth - Disease outbreaks that may be linked to grazing management - Structural problems with fences or handling facilities The USDA Agricultural Research Service conducts research on animal production and protection that can inform grazing management decisions [www.ars.usda.gov/animal-production-and-protection](https://www.ars.usda.gov/animal-production-and-protection). The Food and Agriculture Organization of the United Nations provides resources on animal production systems at [www.fao.org/animal-production/en](https://www.fao.org/animal-production/en). ## Decision Framework for Matching Grazing Intensity to Forage Supply A systematic decision framework helps cervid managers match grazing intensity to available forage supply across seasons and pasture conditions. This framework integrates forage measurement, animal demand calculation, and adjustment rules that prevent overgrazing while maintaining animal performance. The approach draws on principles from the FAO Animal Production and Health division, which provides guidance on sustainable grazing systems at [www.fao.org/animal-production/en](https://www.fao.org/animal-production/en). ### Forage Supply Assessment Protocol Begin each grazing cycle by measuring available forage mass in the target paddock. Use a rising plate meter or a calibrated pasture stick to take 20 to 30 measurements in a W-shaped transect across the paddock. Record the average compressed height and convert to kilograms of dry matter per hectare using a species-specific calibration equation. For mixed-species cervid pastures, a general conversion factor of 250 to 300 kilograms of dry matter per centimeter of compressed height is a reasonable starting point, but local calibration improves accuracy. Calculate the total available forage by multiplying the forage mass per hectare by the paddock area. Subtract a residual of 800 to 1200 kilograms of dry matter per hectare to account for unrecoverable stubble and to maintain plant regrowth potential. The remaining value is the usable forage supply for the grazing period. ### Animal Demand Calculation Determine the daily forage demand for each animal class. Adult red deer hinds consume 2.5 to 3.5 percent of their body weight in dry matter per day. Elk cows consume 2.0 to 3.0 percent. Bison cows consume 1.8 to 2.5 percent. Use the higher end of these ranges for lactating females and the lower end for dry animals or those on low-quality pasture. Multiply the per-animal daily demand by the number of animals in the group and the planned grazing period in days. This gives the total forage demand for the grazing event. Compare this value to the usable forage supply calculated above. ### Grazing Intensity Adjustment Rules Apply the following rules to adjust grazing period or animal numbers based on the forage supply-to-demand ratio: - If usable forage supply exceeds demand by more than 30 percent, reduce the grazing period by one day or increase animal numbers by 10 to 15 percent to improve grazing uniformity. - If usable forage supply is within 10 percent of demand, proceed with the planned grazing period and animal numbers. - If usable forage supply is 10 to 30 percent below demand, reduce the grazing period by one day or remove 10 to 20 percent of animals to a sacrifice paddock. - If usable forage supply is more than 30 percent below demand, do not graze the paddock. Move animals to a paddock with adequate forage or provide supplemental feed. These rules prevent the common failure of grazing paddocks too short, which stresses plants and reduces regrowth. Research on long-term grazing effects on soil chemical properties and plant communities, published in Journal of Environmental Management, indicates that consistent overgrazing degrades soil fertility and alters plant species composition [https://pubmed.ncbi.nlm.nih.gov/37832291](https://pubmed.ncbi.nlm.nih.gov/37832291). ### Seasonal Adjustment Factors Adjust the forage supply assessment and demand calculations for seasonal conditions. During rapid spring growth, forage quality is high but dry matter yield per hectare may be lower than later in the season. Use a 10 to 20 percent safety margin in the supply calculation to account for the lower bulk density of lush spring growth. During summer drought, reduce the usable forage supply estimate by 20 to 30 percent because plants are stressed and regrowth is slow. Extend rest periods by 50 to 100 percent as described in the rest period section above. During autumn, increase the residual stubble height to 1200 to 1500 kilograms of dry matter per hectare to protect root reserves for winter survival. ### Record System for Grazing Intensity Decisions Maintain a grazing intensity record for each paddock that includes the following fields: - Paddock identification number and area in hectares - Date of forage measurement - Average compressed height in centimeters - Estimated forage mass in kilograms of dry matter per hectare - Usable forage supply after subtracting residual - Animal group identification and number of animals - Per-animal daily demand in kilograms of dry matter - Total forage demand for the planned grazing period - Supply-to-demand ratio - Actual grazing period used in days - Post-grazing residual height in centimeters - Observations on grazing uniformity and animal behavior Review these records at the end of each grazing season to identify paddocks that consistently have supply deficits or surpluses. Adjust paddock size, rest period, or stocking density for the following season based on these patterns. ### Troubleshooting Common Supply-Demand Mismatches Three common mismatch patterns occur in cervid rotational grazing systems. The first is chronic supply deficit, where forage supply is consistently below demand. This pattern indicates that stocking density is too high, rest periods are too short, or pasture productivity is declining. Solution: reduce animal numbers by 10 to 20 percent, extend rest periods by 7 to 14 days, and test soil fertility. The second pattern is chronic supply surplus, where forage supply consistently exceeds demand. This leads to rank, overmature grass that animals avoid, reducing grazing uniformity. Solution: increase animal numbers by 10 to 15 percent, shorten rest periods by 5 to 10 days, or use mechanical topping to remove excess growth. The third pattern is high variability between paddocks, where some paddocks have surplus forage while others have deficits. This indicates uneven soil fertility, species composition, or previous grazing history. Solution: regroup paddocks by productivity class and adjust grazing periods accordingly. Apply fertilizer or lime to low-productivity paddocks based on soil test results. ### Professional Escalation Criteria for Forage Supply Issues Consult a pasture specialist or agricultural extension agent if you observe any of the following: - Forage supply estimates consistently differ from actual grazing outcomes by more than 20 percent - Soil test results indicate severe nutrient deficiencies or pH imbalances that limit pasture growth - Weed species dominate more than 30 percent of paddock area despite proper grazing management - Erosion or bare soil patches exceed 10 percent of paddock area - Forage quality analyses show crude protein below 8 percent or neutral detergent fiber above 65 percent for more than one season The USDA Agricultural Research Service conducts research on pasture management and forage quality that can inform these decisions at [www.ars.usda.gov/animal-production-and-protection](https://www.ars.usda.gov/animal-production-and-protection). The FAO Domestic Animal Diversity Information System provides resources on breed-specific forage requirements at [www.fao.org/dad-is](https://www.fao.org/dad-is). ## Frequently Asked Questions ### What is the ideal paddock size for farmed deer? For adult red deer hinds, paddocks of 0.5 to 2.0 hectares work well. Smaller paddocks (0.5 to 1.0 hectares) are suitable for groups of 10 to 20 animals. Larger paddocks (1.0 to 2.0 hectares) work for groups of 20 to 40 animals. Fallow deer can use similar paddock sizes but at higher stocking densities. ### How long should elk pastures rest between grazing events? Elk pastures need 25 to 35 days of rest during the growing season. In dry conditions or on low-fertility soil, extend rest to 40 days. In rapid spring growth, rest can be shortened to 20 days. Measure grass height to confirm recovery before regrazing. ### What is the recommended stocking density for bison on pasture? Bison cows can be stocked at 2 to 8 animals per hectare during the grazing period. Lower densities (2 to 4 per hectare) are appropriate for native rangeland or low-productivity pasture. Higher densities (5 to 8 per hectare) work on improved pasture with irrigation. Bison bulls require lower densities, 1 to 4 animals per hectare. ### Can rotational grazing reduce parasite problems in cervids? Rotational grazing can reduce parasite burdens by moving animals away from contaminated pasture before parasite larvae complete their development. Rest periods of 30 to 45 days allow many parasite larvae to die before animals return. However, some parasites, such as [Haemonchus contortus](/knowledge/parasites/livestock-parasites/haemonchus-contortus), can survive longer and may require additional control measures. Research on benzimidazole-resistant Haemonchus contortus in a wildlife park, published in Schweizer Archiv Fur Tierheilkunde, highlights the importance of integrated parasite management [https://doi.org/10.17236/sat00336](https://doi.org/10.17236/sat00336). ### How do I adjust grazing periods for different seasons? During rapid spring growth, use short grazing periods (1 to 2 days) and short rest periods (21 to 25 days) to keep grass in a vegetative state. During summer, extend grazing periods to 2 to 3 days and rest periods to 30 to 35 days. During autumn, use longer grazing periods (3 to 5 days) and rest periods of 35 to 45 days to build root reserves. During winter, use stockpiled forage or supplemental feed. ### What records should I keep for cervid pasture management? Keep records of grazing dates, paddock numbers, animal groups, grass height before and after grazing, body condition scores, and any observations of animal health or pasture condition. Also record weather data, soil test results, and forage quality analyses. These records help you make informed decisions and track trends over time. ### How do I prevent soil compaction from bison on pasture? Avoid grazing bison on wet soil. Use sacrifice paddocks or feeding areas during wet periods. Rest damaged paddocks for 60 to 90 days. Aerate compacted soil with a pasture aerator or by using shallow tillage. Maintain good ground cover to protect soil structure. ### When should I consult a professional about cervid grazing management? Consult a veterinarian if animals lose condition, show signs of disease, or have high parasite burdens. Consult a nutritionist if you suspect mineral deficiencies or need help formulating supplements. Consult a pasture specialist if soil fertility is poor, weed invasion is severe, or pasture recovery is slow.
