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.

Note: No cement, only compacted dirt and rocks or use of a rock basket as shown in Picture #1.

H-braces can be made with two posts rather than three. If two post design is used then the h-brace needs to be place perpendicular to the fence line. As shown in Picture #2.

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.

Picture #7 Picture #8

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).

Picture #9

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.
