GARDENING : OWLS CAN SOLVE GOPHER PROBLEM.Byline: Joshua Siskin
There are hills and canyons in and around Los Angeles Los Angeles (lôs ăn`jələs, lŏs, ăn`jəlēz'), city (1990 pop. 3,485,398), seat of Los Angeles co., S Calif.; inc. 1850. where gophers are such an enormous problem that gardening is virtually impossible. In parts of Santa Clarita Santa Clarita, city (1990 pop. 110,642), Los Angeles co., S Calif., suburb 30 mi (48 km) NW of downtown Los Angeles, on the Santa Clara River; inc. 1987. Situated in the Santa Clara valley and nearby canyons, Santa Clarita includes the former towns of Canyon Country, and the Antelope Valley This article is about the Los Angeles County region. For the census-designated place in Wyoming, see Antelope Valley-Crestview, Wyoming.
The Antelope Valley , the only way to plant is to sink a fine mesh fence to a 2-foot depth around your garden.
Trapping definitely works, but it is accompanied by the never-pleasant task of extracting the dead animal from the trap's skewers that pierce it on both sides. Oats laced with strychnine strychnine (strĭk`nĭn), bitter alkaloid drug derived from the seeds of a tree, Strychnos nux-vomica, native to Sri Lanka, Australia, and India. are the most popular poison bait, except that lots of people don't like handling noxious noxious adj. harmful to health, often referring to nuisances. chemicals, and you can never be sure if the gopher got away.
Household pets, especially cats, have been known to afford some measure of gopher control, and there is anecdotal evidence anecdotal evidence,

As in so many other areas of life, the solution to our gopher problem may, in the end, come from above, in this case in the form of a bird found throughout the world, a bird that consumes not only gophers but moles, voles, mice and rats as well. This bird is none other than the common barn owl barn owl
Any of several species of nocturnal birds of prey (genus Tyto), sometimes called monkey-faced owls because of their heart-shaped facial disk and absence of ear tufts. Barn owls are about 12–16 in. , a bird no bigger than a crow, with an unmistakable heart-shaped, chalky white, ``Phantom of the Opera'' mask.
The fact that barn owls eat gophers is hardly news. In fact, biologists have long been privy to the knowledge that March and April are the peak breeding months of both owls and gophers. What this means is that there will be plenty of prey for the owls just at the moment when they are hungriest and also have fledglings to feed.
This understanding has led to the reasonable assumption that if you could bring a pair of breeding barn owls into a gopher-infested area, the owls happily would take up residence and rid you of your gopher problem. But this assumption is wrong.
The breakthrough in owl-gopher research was reached when it was discovered that although barn owls are found throughout the world (excepting the higher latitudes), they only will come to an area by their own choosing. When you forcibly forc·i·ble

To build an owl house, sink a 4-by-4-inch pole 4 feet into the ground and build a nesting box to be attached at the top of the pole, which should extend to a height of 12 feet above ground level. The nesting box should be 16 to 24 inches on each side, with landing dowels, an entry hole 6 inches in diameter in front, several -5/8-inch drainage holes at the bottom, together with a clean-out panel, and four -3/4-inch air holes on the side. If placed in the sun, as opposed to under a tree, a slanted roof should be provided on the top of the box, extending several inches over the front and back to give the owls shade. Care should be taken not to place the nesting box in an area of intense vehicle or foot traffic, since owls will not visit such noisy sites.

Just a few qualifications of what the article says. The entrance hole is better if smaller than 6". 5" is fine and helps keep out predators. There is no need, especially around Los Angeles not to mention most of the rest of the country, to bury the post 4' in the ground--18" to 24" is plenty. As far as a canopy roof, there is a brand new plastic-molded nest box on the market that is much lighter weight and much easier to install and needs no canopy. The website is www.barnowlbox.com.
