AG-9AC7-S-14-0155 Technical Specifications, Maps and Diagrams - Page 4 of 36 option is to park at 26N35A which is a dead end/ water drafting area and walk in about the same distance to reach the meadow area.
The current electric fence (FESC2) at LT Creek may be energized at times during the grazing season. This electric fence is also planned to be realigned (rFESC2). Fence construction in this area will be coordinated with the permittee and other ongoing activities as needed.
Location D: Horseshoe Fen (pFESC6): T. 26 N., R. 6 E., Section 20
From the LT Creek area, travel along 26N35 about ½ mile east to the Horseshoe fen area
(item 8). The meadow is located along the north side of road 26N35 and the fen can be reached by walking in a short distance.
Maps and Site Specific Locations: The maps are intended to show only the general size, shape, and location of the fence areas. If the maps conflict with the field marking, the field markings shall govern. Approximate fence locations in Items 1-8 will be flagged with yellow or white flagging. Should boundaries of the work units be unclear to the Contractor, the Contractor shall notify the COR or Inspector. The Contractor may elect to make slight changes in the location of the fences; however, these changes must be approved by the Forest Service prior to erecting the fence. See attached maps.
TECHNICAL REQUIREMENTS
Work Schedule /Operations: The Contractor will notify the COR two days in advance of where and when work will start. Forest Service personnel will be available to answer questions or check areas Monday - Friday, 8:00 am to 5:00 pm. Contractor may work other than these hours and on weekends. Contractor may accompany the Forest Service inspector when conducting final inspections for acceptance and payment. The Forest Service may set the order in which the fences are constructed depending on permittee coordination needs. Camping is allowed as per forest policy.
Fence Materials/ Locations: Materials can be stored and picked up by the Contractor at the
Almanor Ranger District Office, or the Contractor and the COR will agree upon the location of the delivery point or accessible point for any storage of fence materials at the pre-work conference.
Vehicle Operations: Forest roads are generally accessible by two-wheel drive vehicle during the normal operating season but four wheel drive may be recommended for some areas or time periods. For dispensing of fence material, most sites are accessible by truck and ATV/OHV.
However, other equipment for fence construction may include a skid steer and/or a four wheel drive tractor.
No vehicles will be permitted to operate off system roads without approval of the COR. Where allowed, vehicles may approach the area cleared for the fence but vehicles may not cross interior areas of fence.
AG-9AC7-S-14-0155 Technical Specifications, Maps and Diagrams - Page 5 of 36
Fence Clearing: The Contractor will clear a path of brush, forest debris, or other obstructions less than six feet wide. This path, which will lie outside the fence, serves as the access corridor for erecting the fence, and serves as an access for maintenance of the fence.
It may not however be necessary to disturb the ground around the entire perimeter. In meadow areas and in cases where the ground is generally level and free of brush or debris, ground disturbance will not take place.
All clearing will be done by the contractor using a power saw or other hand tools. Material so removed shall be scattered outside the clearing limits. If trees greater than 8 inches dbh need to be removed contact the COR for approval prior to removing. The Contractor shall not use tractor or dozer for clearing. Grading along fence line is not allowable.
Fence Construction – For the Soda Creek project fences, split rails that will be used are western red cedar, ten feet long. Split members will be at least 18 -20” girth (super jumbo size) up to a cross-sectional area at the small end of eight to ten inches. The ten foot length will allow for one foot of overhang on each end. A minimum of four rails per section will be used for a fence height of 4.6 to five feet. The distance between the zig zags will be approximately 16.5 feet and the angle of zigzag will be approximately 130 degrees.
To keep the bottom rails off the ground some of the ten foot rails will be cut into five two foot length “chocks”. One chock will be put under each joint in fence at every zig zag to keep the bottom rails twelve inches off the ground. The chocks are laid out about eight feet apart.
Nails, spikes (80d), or lag screws (5/8 - 7") or 1/2" rebar may be used to secure the rails together.
Drills may be used for rebar to provide 5/8" holes in the center of the rails at each end and in the center of the chocks. A sledge hammer may be used to hit down spikes or rebar.
Tie posts are not necessary if the fence is well zig-zagged. Rails larger than super jumbo size (or greater than ten inches across) may be notched as well as secured with spike or rebar. Notches would be approximately three inches deep.

Fence Construction (Buck and Pole): For the Swain Meadow/Robbers Creek Allotment addition fence, buck and pole fence material will be of well-seasoned pine material or other sound wood free of knots and has the bark stripped from at least one side for quick seasoning. A panel section of buck and pole fence will consist of two A-frame bucks, spaced an average of eight feet apart, with one brace and four rider poles rails attached perpendicular to the standing A-frames.
Bucks - The A-frame buck posts (also called buck sticks) will be a minimum three to six inches in diameter and six feet long. Bucks may be constructed from standard commercially pressure treated wooden posts 6.5 feet long with a 3.5 inch-minimum-top diameter.
Rider Poles - The fence will have four rider poles which will be a minimum three to five inches in diameter and eight to ten feet long, allowing for a maximum one foot of overhang on each end. One rider pole will go on the top, two on the front and one (also called rub pole) on the back.
Cross Braces - The cross brace poles for the bottom of the A-frame bucks will be at least two to three inches in diameter and six feet long. They can be cut from rider poles or other wood pieces (2” x 4”). For wet meadow areas, two cross pieces may be placed on each side at the base of the buck for stability (also called mud stilts).
The A-frames will be set at a 60-degree angle with the notches locked together. Notching Posts may be done with a chainsaw or axe and should be approximately three inches deep. A miter box with a 30° or 40° angle, constructed out of two- by ten-inch lumber may be used to cut the correct angle to join the buck members. The height of the top rider pole will be at least 42 inches or 4.6 feet in height. The bottom rider pole will be attached to the bottom of the A-frame, about eight inches from the bottom of each post. The crosspiece should extend beyond the posts, on the outside of the frame so that the lowest pole can be placed on top of the crosspiece. The lowest rider pole should be no higher than 8-10 to 14 inches above the ground.
To nail posts for A-frame bucks together, 60D-80D nails may be used depending on the size. A single six or eight inch spike may be driven through the center of the intersecting buck posts.
70D spikes may also be used and for nailing rider poles to the bucks. To nail the bottom cross pieces to the bucks, depending on the size 60D common nails may be used. Nails should extend a minimum of two inches into rider poles or cross pieces.

3) FLONE ASPEN STAND FENCING
The identified aspen stands shall have deer proof fence constructed around them to prevent deer from browsing the new growth.
SCOPE
The fence shall be constructed between 25 and 50 ft away from the aspen stems and shall surround the stand completely. The fence may incorporate natural physical barriers such as rivers, cliffs or boulders as long as the fence is constructed in such a way that deer cannot enter the stand. Rocks or logs shall be used to block gaps in the bottom of the fence where deer might be able to get under. The fence shall be constructed of 8 ft t-posts spaced 20 feet apart and inserted into the ground approximately 1-2 feet. The fence shall be a letdown fence so that it can withstand heavy snow loads in the winter. The deer mesh and wire shall be easily laid down in the winter months and easily put up in the spring. The deer mesh shall be attached around smooth wire that spans the top and bottom of the fence. The wire shall be secured to the t-posts with letdown fence clips and a nail. The mesh shall not be attached to the t-posts. Zip-ties or hog rings shall secure the deer mesh around the wire. Corners may be constructed using existing live trees (6 in dbh and larger), rock cribs or h-braces (See project specifications for details).
Corner trees shall be protected with wood braces so that the wire does not cut into and damage the tree.
PROJECT LOCATIONS
The project is located in two general areas on the Lassen National Forest, Almanor Ranger
District. Area 1 ( is in Plumas County located North of Chester CA and Hwy 36 along Plumas
County road 311 (or Warner Valley Road) in Township 29N Range 6E section 21 and T29, R5E sections 15,22,23.
Area 2 is located in Butte County. From Chester CA, South of Hwy 36 to Hwy 32 and the
Skyway in proximity to Philbrook Lake. Township 25N, Range 4E, sections 10 and 11.
TECHNICAL REQUIREMENTS
Support T-posts shall be in the ground about 2 feet and spaced every 20 feet. Smooth wire shall be used to support the deer fence and secure the fence to the t-posts (see pictures #6 and 8). The deer mesh shall be wrapped over the top smooth wire about 6 inches and secured to itself with hog clips or zip ties. The bottom smooth wire secures the fence to the bottom fence clip. Deer mesh shall be wrapped in the same way as the top with 6 in overlap and secured with hog clips or zip ties (see pictures #7 and 8). Two fence clips (see picture #9) per t-post, tree or wooden post is enough to secure the fence. Wire shall be held in the clip. The deer fence is not strong enough to hold the weight of the fence. When the fence turns a corner the appropriate support shall be
AG-9AC7-S-14-0155 Technical Specifications, Maps and Diagrams - Page 22 of 36 installed. Live conifer trees are the preferred support but h-braces or rock cribs may also be installed where suitable trees don’t exist. Trees selected as corners shall be live conifers (snags and aspen trees are not suitable) and at least 10 inches or greater diameter at breast height. The tree shall only support the corner t-post. To protect the tree from damage use pieces of 2X4s or suitable found logs, cut to 6-12 inches, (logs shall be approximately 3-4 in dbh) between the wire wrap and the tree (see pictures 3, 4 and 5). Then use wire to secure the top of the corner t-post
(see picture #1). If no tree is available install a rock crib or an h-brace or suitable wood post (see figure 1 and pictures #1, 2 and 6). If there is a straight away longer than 300 ft (about 15 t-posts) then use a wooden fence post or tree to add extra support. The fence is a letdown fence so use a chain link brace band placed over the corner t-post. The top smooth wire shall be secured to the brace band allowing for the entire mesh/wire fence to be laid down on the ground. This brace band should easily slide up and down the corner t-post for easy let down and put up. The deer mesh may then be loosely attached, via large zip ties at the corner posts or wrapped around the corner t-post and secured to itself. The wire and deer mesh shall move easily to the up position or the down position and the mesh should not be attached to the support t-post put held up with the fence clips.

Deer Fence Construction
Support T-posts should be in the ground about 2 ft and spaced every 20 ft. Smooth wire will be used to support the deer fence and secure the fence to the t-posts (see pictures #6 and 8 ).The deer mesh should be wrapped over the top smooth wire about 6 inches and secured to itself with hog clips or zip ties. The bottom smooth wire secures the fence to the bottom fence clip. Deer mesh should be wrapped in the same way as the top with 6 in overlap and secured with hog clips or zip ties (see pictures #7 and 8). Two fence clips (see picture #9) per t-post, tree or wooden post is enough to secure the fence. Make sure the wire is held in the clip the deer fence is not strong enough to hold the weight of the fence.
When the fence turns a corner the appropriate support should be installed. Live conifer trees are the preferred support but h-braces or rock cribs may also be installed where suitable trees don’t exist. Trees selected as corners would be live conifers (snags and aspen trees are not suitable) and at least 10 inches or greater diameter at breast height. The tree should only support the corner t-post. To protect the tree from damage use pieces of 2X4s or suitable found logs, cut to 6-
12 inches, (logs should be approximately 3-4 in dbh) between the wire wrap and the tree (see pictures 3, 4 and 5). Then use wire to secure the top of the corner t-post (see picture #1). If no tree is available install a rock crib or an h-brace or suitable wood post (see figure 1 and pictures #1, 2 and 6. If there is a straight away longer than 300 ft (about 15 t-posts) exists then use a wooden fence post or tree to add extra support. The fence is a let down fence so use a chain link brace band placed over the corner t-post. The top smooth wire is then secured to the brace band allowing for the entire mesh/wire fence to be laid down on the ground. This brace band should easily slide up and down the corner t-post for easy let down and put up. The deer mesh can then be loosely attached, via large zip ties at the corner posts or wrapped around the corner t-post and secured to itself. The wire and deer mesh should move easily to the up position or the down position and the mesh should not be attached to the support t-post put held up with the fence clips.

Picture #3 #1. Chain link brace band allows for the fence to easily slide down the t post. T-post installed at the corners need to be positioned so that the smooth side faces the tree.
Deer mesh should be loosely secured to the t-post with zip ties (#2) or by overlapping the mesh around the t-post and securing the mesh to itself with zip ties.

Picture #4 Picture #5 Corner trees should be alive and large enough to support the weight of the fence. 8 ft t-posts are installed adjacent to the tree to support the mesh fence. The top of the t-post needs to be supported by the tree. Wire should be wrapped around the tree with either 6-12 in log supports or cut 2X4 supports to not damage the tree. The wood supports are not attached to the tree. They are held in place by the wire. The wire may be attached to the top of the t-post only (as shown in Picture #5) or at the top and the bottom (as shown in Picture #4).

Picture #6:
Rock Cribs can be constructed where live trees are not available where a corner is needed. Note 5.6 ft tall t-posts are installed to support the rock basket but 8 ft t-posts are installed to support the mesh fence. Where possible deer mesh should be stretched to close any gaps created by the rock crib.

Smooth wire stretches along the top and bottom of the fence and will be attached to the t-posts via steel fence clips (picture 9). T-posts are spaced every 20
ft. Mesh should not be attached to the t-posts. The smooth wire needs to be able to be dropped during winter months to help protect the fence from snow loads. The mesh will overlap the top wire and will be secured to itself with either zip ties (picture 7) or hog rings (picture 8).

Topography created gaps between the ground and deer mesh greater than 6 inches should be filled in with rock or logs to prevent deer from entering exclosure underneath the wire.
