The health and vigor of big game populations are closely correlated to the quality and quantity of forage in key areas. Key areas are defined as those areas where deer or other big game have demonstrated a definite pattern of use during normal climatic conditions over a long period. Current research from this project focuses on improving the quality and quantity of forage on key big game ranges statewide. Research findings will increase the availability of native plant materials used in habitat restoration projects, increase our understanding of their planting requirements, increase the effectiveness of range development equipment, and refine and develop range restoration techniques for range restoration work.
Research started in 1956 to investigate ways and means of improving the productivity of rangelands in Utah.
- In 1956, seed was available for less than 10 species that were adapted to Utah rangeland. There are now, through studies, evaluations and development, over 115 species for which seed is available and that are seeded to improve wildlife habitat and restore rangelands.
- In 1956, there was virtually no equipment or techniques available for site preparation or seedings of rangelands. Research center personnel worked on the development, testing and improvement of rangeland type drills, pipe harrows, disk-chains, seed dribblers, shrub seeders, scalper-seeders, chains and swivels, transplanters, spraying equipment and aerial seeders.
- To find out when, where, and how species establish and grow, more than 10,000 plant accessions have been placed in germination studies, seed and evaluated in test plots and out plantings throughout Utah. Nutrition; drought tolerance; palatability; seedling vigor and establishment; disease and insect resistance; fire tolerance; adaptation; competitiveness; and response to utilization are some of the characteristics evaluated in making plant selections.
- One cannot improve rangelands without seed. Once species were selected, a seed source had to be developed. To have sufficient seed at reasonable prices, wildland and commercial seed production and storage techniques have been investigated developed.
- Pre-treatment and long term post-treatment studies have been established to facilitate a better understanding of how to improve and enhance benefits for the future. To insure improvement in productivity, soil protection, water, and vegetation, each new project is adapted to incorporate the latest and best information on the species being seeded and techniques and management being employed.
Research findings are used in:
- restoration and enhancement of rangelands; enhancing soil stabilization; improving water quality and riparian sites on private ranges and farmlands and on state and federal lands
- reclamation of disturbed sites (mines, highways, petroleum extraction and land fills)
- beautification of parks, recreational areas, summer home and cabin sites, highways, and ski areas
- and in the commercial seed industry.
Project personnel have been involved in the development and release for commercial production of 15 selected and tested plants and in the development, promotion, and use of over 100 other species of rangeland plants. Development, demonstration and promotion of plant materials has resulted in the creation and development of Utah's thriving native seed industry and in the enlargement of Utah's commercial seed production industry.
Project personnel have worked with the Utah Department of Agriculture and Food in developing seed quality testing standards for native species and with the Utah Crop Improvement Association in establishing wildland seed certification.
