Our community has a Agricultural Exemption because we have a Grazing Lease. This grazing lease saves each of us A LOT OF MONEY on property taxes every year. The cows are usually brought up only during the summer. There is not that much pastureland in the community and if cattle are fenced out of too much pasture, then there is not enough fodder for the cows and the grazing lease could be at risk.
Please consider that fencing in pasture areas adversely affects us all.
Consider how much area you really need to fence for you own livestock.
Consider removing fencing that is no longer useful.
Consider taking down sections of your fence to allow cows in to graze.
Consider using more temporary and/or wildlife friendly fence options.
Barbed wire is not recommended for horses.
Downed barbed wire fencing is dangerous and should be removed.
A fence that is friendly to wildlife should:
Allow animals to jump over and crawl under easily without injury
Be highly visible for both ungulates and birds
