1 PASTURE AND RANGE Revised 2/27/2018 PURPOSE To assist the Agriculture Education teacher in stimulating interest in the study of range management and natural resources. OBJECTIVES - Develop ability to identify range plants. - Develop ability to classify range plants by: life cycle, growth season, origin, and forage value. - Evaluate range site for condition and habitat. - Recommend range site management practices. COMMON CORE REFERENCES 7-8th Grade CCSS.ELA-Literacy.RST Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks. 9-10th Grade HS-ESS3-2. Evaluate competing design solutions for developing, managing, and utilizing energy and mineral resources based on cost-benefit ratios.* 11-12th Grade HS-ESS2-5. Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes. EVENT RULES 1 Plant Identification At least 20, but no more than 25 plants will be staked and numbered for identification. Live plants from the State Master Plant List will be used. Transplanted specimens may be used if they are not wilted. Prohibited Noxious weeds can only be used as mounts 2 Scoring A scorecard will be used for the identification portion of the Career Development Event. Participants must write in the common name of the plant and check its growth characteristics. Characteristics are: A. life span - annual or perennial B. growth season - cold season or warm season C. origin - native or introduced D. resource rating - desirable or undesirable Ten points per plant will be allowed for this part of the event. Six points for the correct name and one point for each correctly checked plant characteristic. If the plant name is missed, no credit will be given for the characteristics. 3 Time Limit Participants will be allowed one minute per plant for the identification portion of the Career Development Event. Participants will move to the next plant, in sequence, when time is called. 1 of 16

2 4 Range Practices, Sites, Condition and Habitat This part of the Pasture & Range Evaluation Career Development Event is comprised of four sections: A. Stage of plant succession B. Kind of ecological site C. Recommended range management practices D. Beef cattle habitat evaluation Participants will make decisions from evaluating a small area of range (usually 50 ft square). Participants will be advised by the event official what conditions are to be considered. This will be done with a written problem or scenario given to the participants. Total point breakdown is as follows: Stage of plant succession 25 points Kind of ecological site 25 points Range management practice 25 points Beef cattle habitat score 25 points TOTAL Recommended Management Practices See Guide to Management Practices for Beef Cattle 6 Forage Utilization Utilization plant will always be utilized first to determine stocking rate A B C If the forage utilization is heavey severe: If the forage utilization is moderate: If the forage utilization is light or none: Decrease Stock Rate Contiune Present Stock Rate Increase Stock Rate EXAMPLE: Stated objective is a 25 and the plant is heavily grazed, students will always Decrease Stocking Rate EVENT FORMAT 1 Site Card Forage objective, distance to water, depth of soil, and any special factors to be included in the management scenario. 2 Soil Texture Soil samples will be provided at site card. 2 of 16

6 GUIDE TO MANAGEMENT PRACTICES FOR BEEF CATTLE 1. CONTINUE PRESENT MANAGEMENT Use when the current management objective is met by the present condition of the site. 2. BEGIN A PLANNED GRAZING SYSTEM Use when forage production and /or forage diversity is the limiting factor. 3. CHANGE THE KIND OF GRAZING/BROWSING ANIMAL Use when grazing accessibilty combined with Light/None Utilization and grazing restraint is the limiting factor because of terrain >15% or woody cover. *Do not change the type of animal if the Utilzation Plant shows Moderate, Heavy, or Severe Use by the current species of livestock and the slope is >15%. 4. APPLY WOODY PLANT CONTROL Use when grazing restraint is the limiting factor because of woody plants. 5. DECREASE STOCKING RATE FOR BEEF CATTLE Use when forage utilization is Heavy or Severe. 6. INCREASE STOCKING RATE FOR BEEF CATTLE Use when forage utilization is Light or None. 7. CONTINUE PRESENT STOCKING RATE - Use when forage utilization is Moderate. 8. DEVELOP WATER FOR BEEF CATTLE Use when water is the limiting factor because of distance to water. 9. PLANT ADAPTED FORAGE SPECIES Use when the Similarity Index is 10% or less. This usually occurs on land that has been farmed and not reseeded. Defer grazing until the Desired Plant Community is established. Control competitive plants and invasive species with fire, grazing, or herbicide. 10. USE PRESCRIBED FIRE Can be used for plant control or to enhance palatability of forage.
