As I have mentioned last time, one of the measures I have gone to for predator deterrence is electrified netting. The netting is very easy to set up and move around and generally works well. It does have some limitations, however. One is that it's relatively fragile.
Several times I have found a section of netting down on the ground. Cameras have never been positioned the right way to show me what happened, but I have assumed it was a deer that got caught on the top of the fence coming in or going out, and in its effort to free itself, it pulled up some of the posts. A coyote might be another possibility, or a bobcat--all of them are present to some degree. I haven't seen hogs or bears, although a bear wouldn't be completely out of the question.
The most recent time this happened, it was very obviously a deer:
The hoof marks in the dirt show where it flailed around a bit trying to get out. Another first for this time around is that the netting was actually damaged. A couple of non-conductive vertical strands were broken, and two horizontal conductive ones were, as well.
Premier1 includes a little repair kit with each roll of netting; it has small rolls of each type of cord in the net, along with a few brass crimpers to put around the repair knots to help ensure a conductive bond. The number were too limited for serious repairs, so I got a package of fifty 14-8 copper crimp sleeves. They have a flared end that enabled them to slide over the square knots I tied to join the replacement pieces to the broken ends of the existing netting.
Then a quick squeeze with a pair of pliers and the repair was done:
The end result isn't particularly pretty--it's obvious there was damage--but it is again fully functional. That's all that matters.
