Ropes shall be worn on the left side of scout belt secured with an appropriate Knot Master knot. 2. When a Scout or Scouter proves he is ready for advancement by tying all the knots of the next rank as witnessed by a Scout or Scouter of that rank or higher, he shall trade in his old rope for a rope of the color of the next rank.

It can be difficult to untie when wet. 2. Loop Knot The loop knot is simply the overhand knot tied on a bight. It has many uses, including isolation of an unreliable portion of rope. 3. Square Knot The square or reef knot is the most common knot for joining two ropes. It is easily tied and untied, and is secure and reliable except when joining ropes of different sizes. 4. Two Half Hitches Two half hitches are often used to join a rope end to a post, spar or ring. 5. Clove Hitch The clove hitch is a simple, convenient and secure method of fastening ropes to an object. 6.

  • Orientation to Rope Management
    Chapter 10 – Orientation to Rope Management Upon completion of this chapter, you will be able to: • Describe the circumstances where the use of ropes and knots is appropriate for GSAR. • Compare and contrast the types of rope that are encountered in SAR and the relative advantages and disadvantages of each. • Describe and demonstrate proper rope care, handling, and management. • Define the following: dynamic rope, static rope, tubular webbing, flat webbing, accessory cord. • Recognize and demonstrate tying the following knots: Figure Eight on a Bight, Figure Eight Follow Through, Figure Eight Follow Through Bend, Ring Bend (Water Knot, Tape Knot, Overhand Bend), and Italian Hitch (Munter Hitch). • Define carabiners and describe their use. • Describe proper handling of carabiners. • Demonstrate a single point anchor. • Demonstrate the use of a rope for a hand line. • Demonstrate a belay for an assisted raise or lower using an Italian Hitch. • Use the appropriate belay signals during an assisted raise or lower. ORIENTATION TO ROPE MANAGEMENT Introduction The responsibilities of a GSAR member include the ability to perform basic rope management functions. This includes tying of rescue knots involved in a ground-based evacuation and, maintaining and managing a rope(s). This course qualifies the GSAR member to aid or assist in stretcher carries through uneven terrain under the supervision of a certified Ground Search Team Leader. It does not qualify the GSAR member to participate in technical rescues The occasions for which ropes and knots are required in GSAR are limited. The most likely circumstances necessitating their use include: • As a safety line for a stretcher carry on low angle slopes • As a hand line on a slope • As a tool in shelter construction It is recognized that some groups utilize more advanced rope management techniques such as rappelling or embankment rescue techniques in ground search applications.

  • Wildlife: Regional Forester Sensitive Species (Rfss)-Plants
    WILDLIFE: REGIONAL FORESTER SENSITIVE SPECIES (RFSS)-PLANTS (1) Overview Several sensitive plant projects involving monitoring were planned in 2005. These projects were all either habitat improvement projects or monitoring of a mitigation that was required for another project. However, due either to lack of a sufficient burn window or to litigation, only one of these projects was implemented: Kawishiwi Admin Site Botrychium Transplant. Lack of a burn window prevented treatments from being implemented for a Virginia EIS moonwort project and a Trygstad Sale barren strawberry project, and litigation of the Tomahawk EA prevented implementation of a Botrychium habitat improvement project. Baseline monitoring has been conducted at all of these project sites, and follow – up monitoring would be conducted after treatments occur. For the Kawishiwi Admin Site Botrychium Transplant, a large population of the rare matricary grapefern (Botrychium matricariifolium) was growing where the parking lot was planned for the new Admin Site. To mitigate impacts from the project, we attempted to transplant individuals to 2 nearby sites using a tree spade as well as by hand using a shovel. Transplanting occurred in Fall 2004, and monitoring occurred in Summer 2005. Survival of individuals was measured in plots. 65% of transplanted individuals survived across all plots. Monitoring will be repeated in 2006. 1) Matricary grapefern population that will 2) Tree spade in process of transplanting 3) Completed transplant plug be impacted by parking lot construction WL.
