how do tornadoes affect animals

On another scale, few animals have "personal property" that can be lost in a tornado or flood. All a coon or turtle has to do is survive. Their home is where they choose to be at any particular moment. One group of animals with structural assets are birds with nests, and indeed this spring's natural disasters have eliminated many a family of bird. The food chain can be affected as a result of a tornado. There can be water contamination, and debris can crush animals. They may walk into fires, and there can be gas leaks, which they may think is water. Most areas affected with trees may snap and kill animals below. Farm animals may get injured by falling barns and sheds.

Any natural disaster calls for prolonged introspection, especially facing the loss of life. Eventually curiosity turns us onto other consequencesthe wildlife and surrounding habitats that the storm also left in its path. How do plants, birds, and other wildlife fare after a tornado tears through an area? As weather systems go, the impact of hurricanes is easier to study because tornadkes broad spread and brooding nature makes them easier to predict. Despite the many mysterious surrounding twisters, we do have some knowledge about how they affect nature.

Birds are lucky in that they can detect minute pressure shifts before unusual weather arrives. However, Kenn KaufmanAudubon field editor and author, believes that our feathered friends are worse at predicting tornadoes than we are because the twisters move so fast and are so localized. There is one thing that birds can do more effectively than us, though, he saysescape.

Like hurricaneswhich can actually spawn twisterstornadoes are hugely what does vfx stand for and can flatten things in their paths even more severely. Trees where birds nest are ripped from the ground, and debris from shredded structures and vegetation obscures underground burrows. Any birds caught up in the storm are presumably killedalthough there is no real way of measuring wildlife deaths after a affecr.

Bodies are hard to find amid the debris, and over long distances in the rural areas where tornadoes often strike. Furthermore, to gain a real howw of the mortality, experts would require pre-tornado wildlife census how to hide cables on a wall which to compare the numbers of surviving individuals after the storma rarity. David Kinga research wildlife biologist with the USDA Forest Service in Amherst, Massachusetts, adds that when it comes to the effect that tornadoes have on wildlife, direct mortality is less of a concern to conservationists.

The habitat shifts from forest to shrub, making way for different species to move in to the area. He adds to that list the chestnut-sided and prairie warblers, as well brown thrashers.

As illustrated by birds, as a forest undergoes transitions between destruction, regrowth, and maturity, the species that inhabit it may change, King tornadles. When it comes to birds, the timing of tornadoesstormy late spring and early summeroften coincides with nesting season. After the storm passes, birds are often drawn back to their established territories.

Kaufman offers a purely anecdotal account. He recalls that after a tornado passed through Agfect in the late she noticed a posse of barn swallows repeatedly circling one area. Afterward, he realized a barn had stood there before the tornado struck, and was likely where the birds had built their nests. The birds could not have rebuilt in the area, since everything was gone.

While much remains unknown, King loosely compares the tornado-stricken habitats is to those devastated by fire: Some landscapesespecially forests actually thrive after tornsdoes strikes. Fallen branches provide more cover, nooks, and what is the climate like in alabama where animals can take cover.

Rotting wood also spurs new growth as it fertilizes the soil. The benefits are significant enough that ecologists suggest authorities refrain from clearing forests of damaged vegetation after severe weather events.

Believe it or not the U. For some birds, change is salvation. King offers a hopeful anecdote in the form totnadoes the whip-poor-willa how to wire a relay for electric fan bird that faces habitat loss.

In forests, fallen ajimals give a photosynthetic boost to the lower, shrubby levelan ecosystem that birds like the whip-poor-will need more than deep, shadowy forest.

Once, after a tornado passed through Broomfield, Massachusetts, King recalls that whip-poor-wills populated the area where new shrubland opened up to the sky.

Birds Tell Us to Act on Climate

Tornadoes have various harmful effects to the ecosystem. One is that tornadoes can level entire habitats, which endangers the animals living in those habitats. Also, tornadoes can kill and displace animals, which causes imbalance in feeding relationships. Tornadoes help cause water pollution, which can affect the animals who drink that water. Animals can be affected two ways bec ause sometimes they can help other people after tornadoes by sniffing around and tracking the scent and then barking. But sometimes the animals are also hurt, they can get stuck underneath the pieces of wood and other trash and they get injured. For example in Oklahoma the tornado hurt many animals; some were injured; the animals that got hurt the most were .

The funnel of fury that passed through Tuscaloosa, Alabama, in late April left thousands of people reeling with personal losses of property, pets, and even lives. The terrifying tornado destroyed homes, businesses, and entire communities. A different environmental tragedy struck the Midwest as record-breaking floods breached levees of the country's mightiest rivers. Floods and tornados can be devastating from a human perspective, and people must be our first and foremost concern.

But some have asked, how do such natural disasters affect native wildlife? The answer is simple. The overall impact on natural ecosystems and wildlife communities is minimal in the long run. Although the local impacts of two-story high flooding or mph winds are evident immediately, all species native to an area had ancestors that were able to weather similar extremes of wind and water.

With us today are the species that have persisted because former generations faced similar weather phenomena and survived. Although temporarily gone from wind-ravaged or flooded areas, birds and other animals will soon return. Native trees that have disappeared will soon be replaced by seedlings of the same species. Although of small consolation to a homeless family or the owner of lost or damaged property, no native species of plant or animal will be lost because of tornados or floods.

We do not perceive wildlife as suffering the devastating effects from floods and tornados in the same way as people because we measure impacts differently for wild animals than we do for ourselves.

With people, and even with our pets, we empathize with each individual who suffers. We have all seen photos or videos of someone stranded atop a house in the floodplain of a swollen river, people examining a pile of wood, metal, and paper that was once their home, or police searching for a missing person beneath a collapsed building. Even the rescue of a pet can make national news. And most people relate personally and with empathy to each incident.

In contrast, with wild animals we hear a few stories of the plight of individuals, but for the most part we focus on how a population or the species itself fared. Wrens and robins unquestionably were killed or displaced from many local communities in Alabama by tornados.

But no species of bird was irreparably impaired. Other individuals of each species will eventually return, emigrating from surrounding unaffected areas. On another scale, few animals have "personal property" that can be lost in a tornado or flood.

All a coon or turtle has to do is survive. Their home is where they choose to be at any particular moment. One group of animals with structural assets are birds with nests, and indeed this spring's natural disasters have eliminated many a family of bird.

But birds are resilient. In the long run, more nests will be built and more eggs will be laid, eventually even in what are now destroyed habitats. Among other property losses by wildlife, beavers lose dams and lodges due to powerful flooding. But in the nature of beavers, they simply set about repairing the damage as soon as water levels decline, and their life goes on.

Despite the worst weather-related natural disasters the world can offer--floods and tornados, as well as hurricanes, droughts, and forest fires--the ancestors of all our native wildlife evolved to deal with them.

None of these phenomena ultimately affect healthy populations of wildlife. And of course no wildlife affect the weather. But humans are different. Personal lives can be permanently altered by the vagaries of weather. And we are different in another way in that we influence some natural disasters. Damage from some floods can be attributed to the configuration and structural integrity of levees, dikes. We are responsible for some out-of-control forest fires because we have suppressed natural burning patterns.

Are we also responsible for dramatic climate changes brought about by carbon dioxide emissions emanating from industrial countries like ours? The wildlife doesn't care, but should we?
