Bert Lowry, BLM Wildlife Biologist, Biolo-gist, demonstrates at left, erosion to students from the South Elementary school's summer outdoor science class. At right students stu-dents learn by doing. They are shown how the roots from pinon and juniper trees lake away the moisture needed for grasses and other plant species. Each student then dug down to find the roots for himself. BLM participates in outdoor science program District manager, Harold E. Isaacson, reported that the BLM recently participated in the Outdoor Science Program sponsored by the Cedar City South Elementary School. According Ac-cording to the principal and spark plug, Clemont Adams, the program involves about 60 students from Grade 1 through Grade 6 and will last for a period of five weeks during the summer. At the request of Mr. Adams the Cedar City District hosted host-ed two field trips and demonstrated dem-onstrated conservation principles prin-ciples of soil moisture and vegetation relationship-Bert relationship-Bert Lowry, Wildlife Bio-logist Bio-logist presented a program on the North Hills revegeta-tion revegeta-tion project. The students were shown the extreme competition competi-tion for water between pinyon-juniper pinyon-juniper trees and more desirable desir-able vegetation such as grasses. gras-ses. It was also explained how the grasses protect the watershed water-shed as well as provide feed for wildlife and livestock. On the second day, Area Manager, Gordon Staker, led the group into the Escalante Valley. Here it was demonstrated demon-strated that sandy soils absorb ab-sorb rain water faster than clay soils. Also, soils which have plant cover absorb more water and thereby are more stable than barren soils. A comparison was made of pounds of plant growth produced pro-duced per acre from nine inches of rainfall and that produced from one acre of irrigated ir-rigated alfalfa. |
