McCLAIN The Associated Press Natural wildlife habitat is being lost to the constant encroachment of humans. Many wildlife species have adapted to living in proximity to humans but cannot as their needs for food, shelter and nesting are not supplied by the average urban landscape. The urban lot can be landscaped to attract desirable wildlife and consequently appear professionally and tastefully designed and maintained. It is not difficult to landscape for the benefit of wildlife. It takes understanding and planning. Individual plants are selected because of their ability to provide food, cover, nesting, or all three. When planning their placement in the landscape, consider variety, density, and sequence. Greater variety of plant materials will attract greater variety of wildlife species. Density is important to birds and other wildlife in winter. Evergreens offer shelter from cold winter winds when deciduous shrubs have lost their leaves. Many animals need a sequence of small to large plants. Planting a sequence of trees, shrubs, flowers, and grasses with the largest in back descending to the smallest in front gives wildlife the opportunity to reach cover quickly. Below is a list of plant materials preferred by wildlife. These plants are also good ornamental landscape material.

For many Americans, it's time to get out the electric bug zapper. The continuous snap, crackle and pop coming from a zapper on a summer evening has convinced many homeowners the traps are effective in ridding porches and patios of marauding mosquitoes and no-see-ums. But wait, say some scientists who study insects. Too often, they believe, bug zappers not only are ineffective against biting bugs, but do more harm than good. For instance, a study by the University of Delaware at Newark analyzed 13,789 insects zapped by electric traps and found only 31 — less than one-fourth of 1 percent — were biting bugs "seeking blood meals at the expense of homeowners." Nearly half were non-biting aquatic insects such as caddis flies and midges that feed fish, frogs, birds and bats, the study found. And another 14 percent were insects that actually attack pests, such as wasps, ground beetles and ladybugs. "The heavy toll on nontarget insects and the near absence of biting flies in catches suggest that electric insect traps are worthless for biting fly reduction," concluded Douglas W. Tallamy and Timothy B. Frick, who conducted the study. Tallamy, an entomologist, said insects have been described as the glue of the ecosystem. "They are such an important component of the food chain that, if removed, the ecosystem would fall apart," he said in an interview. "If you remove the source of food for birds and fish, you don't have birds and fish anymore. A number of mammals also depend on insects." Sal DeYoreo, president of Flowtron Outdoor Products, a manufacturer of electric traps in Melrose, Mass., disputed the Delaware study. DeYoreo also contended that zappers "are a safe alternative to chemical insecticides, which when sprayed, kill all in their path," including breeding sites. And insecticides have the added danger of affecting the bird food chain by poisoning insects, he said. Electric traps typically use ultraviolet light to lure flying insects to an electrified metal grid, which Tallamy said does not at-, tract mosquitoes and explains why so few were found in the traps. But he said one of the most important reasons tor the traps' failure is that mosquitoes are far more attracted to the carbon dioxide exhaled by people. DeYoreo said newer, state-of-the-art traps, use lures similar to cows' breath that are; more attractive to biting bugs.
