How might the number of oak trees in a park affect the number of squirrels that can live there?
444715
Squirrels eat acorns when they can't get picnic food, and make their homes in trees.  They are somewhat territorial, so the more trees there are, the more squirrel families the park can support.\n\nNot that you want more squirrels.  Rats with bushy tails.

Read:\n\nhttp://en.wikipedia.org/wiki/National_parks\nhttp://www.nationalgeographic.com/refuges/\nhttp://www.nps.gov/\n\nI'm not going to do your homework for you, but I will give you something to think about: one issue that faces national parks is access vs. preservation.  While the park service wants as many people as possible to see the parks, people tend to cause erosion, pollution, littering and other forms of damage.  How should we balance these conflicting goals?

increased owl population would cause a decrease in mice population which in turn would cause an increase in plant population - this ones right

Squirrels mate in the Winter, and you can often see males chasing females up, down, and around trees. Once mated, both the male and female build the nest.\n\nEastern Gray Squirrels usually live in forests, but they are also seen in yards, gardens, and city parks. Basically, they live anywhere there are large, deciduous  trees (trees whose leaves die in the Fall).\n\nThese squirrels live in trees year-round, either in cavities or nests they build out of leaves. Cavities are often old woodpecker holes. Nests are usually high up in tree crotches. Nests are hard to see in the Summer, because they are made with green leaves, and are hidden by foliage (leaves on the trees). They are easy to see in the Winter, when the nest leaves have turned brown and tree leaves fall to the ground.\n\nThe trees most commonly used by Eastern Gray Squirrels to live in are White Oak, American Beech, American Elm, Red Maple, and Sweetgum, though they will use others also.

I won't answer your question directly, since it's YOUR homework.  However, one thing that I will tell you is that wildlife needs food in its habitat.  So, if you can think of a forest management practice that increases the availability of food for an animal, you have found a way to improve the habitat for that animal.  I hope that helps you.

Yes, I live right in the middle of Denver and there are several wild foxes that I see regularly. They use the sewers to get around - I've seen them go down into them. I can't imagine that they live in there, but then, I can't imagine where else they're living, either. In someones small back yard? Because there's no open space or wooded area and the park is really busy.  There are also raccoons in the area - there was a big commotion at my house a couple of weeks ago and I woke to find two HUGE raccoons in the house - they had come in through the cat door, but I have no idea how. It would be like me climbing through the bathroom window - I suppose I could do it, but it wouldn't be easy and it wouldn't be pretty.

They can kill off plants or animals that other animals compete with causing an overpopulation of that species. Or they can introduce a new species into a previously stable ecosystem. The new species may have no competition in the new environment and may overpopulate or it may eat another species and wipe it out.

As Bay Area suburbs spread into the surrounding oak woodlands, homeowners are forgoing traditional lawns in favor of designs that showcase and preserve their heritage oak trees. \n\nAnd, while doing so, they're learning how to landscape in ways that protect the oaks and provide low-maintenance, attractive, water-saving gardens to go with them. "Clients are increasingly aware of the value of their oaks and are asking for native plants. There's been a significant shift in even just the last three to five years," said East Bay landscape architect Michael Thilgen. "In addition, the native-plant-nursery industry has expanded greatly. We're moving well beyond the handful of species that were available a decade ago." \n\nThilgen said water conservation, habitat loss, and the high costs of pesticide and herbicide use associated with some traditional styles of landscape design are also pushing people in the direction of using native plants. \n\nLush, irrigated landscapes can spell eventual death for stately oak trees, according to Thilgen. Lawns and plants that require regular watering, such as rhododendrons and hydrangeas, should be planted far from oaks. While some landscapes are large enough to accommodate both drought-tolerant features and irrigated areas, small lots can have their plant choices dictated by a single large oak. \n\nWatering can cause oaks to succumb to several diseases that rarely kill forest trees. Oak root rot and crown rot, which thrive in warm, moist soils, are a particular problem in ornamental landscapes, although easily mitigated by minimizing irrigation and other stresses on trees. A healthy tree is more likely to resist disease. \n\n"As you modify the environment, you increase the risk to oaks," said Ron Lutsko, a San Francisco landscape architect whose designs frequently include oaks. "We consider a lot of factors in our designs: irrigation, grading, trenching, soil preparation and species selection." \n\n"Oaks are much more offended by grade changes than by irrigation," Thilgen said. "I look closely at the bases of the trunks when I suspect that soil has been filled in the past. The trunk should flare where it goes into the ground." \n\nAnother threat to native oaks has come in the form of sudden oak death, a virulent forest pathogen that has spread throughout the Bay Area, and concern is growing over how to protect landscape trees, especially on the borders between urban and wildland areas, where the disease is most prevalent. \n\nDozens of other plant species may spread the disease. California bay laurel is the worst offender. In the wild, spores that carry sudden oak death are spread by windblown rain and can be carried down streams, but humans may also spread spores while they are hiking, bicycling, moving firewood or by planting infected nursery stock. Some mulches and compost may also carry the spores. \n\nKatie Palmieri, a public information officer for the California Oak Mortality Task Force, suggests that homeowners concerned about sudden oak death begin by visiting the task force Web site. \n\n"The ... site includes maps of infested areas, affected plants, disease symptoms, suggestions for the care of oak trees, the prevention and treatment of (the disease), and lists of trained arborists and other helpful contacts." \n\nAlthough research hasn't yet produced a cure, specimen oaks in vulnerable situations can be treated with Agri-Fos, a fungicide that may prevent the disease or slow its progress if caught early. "Although alternative treatments have been promoted, they have not been scientifically proven to be effective, nor have they been approved by the Department of Pesticide Regulation for use against this disease," Palmieri said. \n\nNurseries in California are subject to inspections, but movement of plants and landscape materials is not restricted within the quarantined counties.

They can hunker down in deep grasses. The snow and grass act as insulation keeping them warm.\n\nWhat's cooler (pun intended) than this is to look at tree squirrels, who have nests high in trees open to the blowing wind. Even they stay warm while being that exposed. The nests help trap body heat while breaking the wind.\n\nNature has some remarkable methods to keep animals warm.

I get deer in my back yard from time to time. They eat the bark off whatever trees I try to plant.\n\n I have a hedgehog and a family of ringneck doves.  A magpie, two voles have a nest under my patio, a wren has a nest under the eave of my front porch.\n\n An owl did live in my back yard but the tree was 300 years old and fell down a few years ago. The owl moved to the woods behind my house. I still hear him hunting at night.\n\nLast spring, I saw a wild boar at dawn but that was only once.\n\nFunny thing is, I live about 20 minutes from the middle of downtown (city of 500,000). Wild, huh?

It depends on the species. Some will travel very far to follow, or find, food. Some will travel during different seasons.

I dont agree with the first two answers, just because the plants dont get pollinated it doesnt mean they will die, they just will not be able to reproduce. \nIf all animals die, there will be a major disruption in 2 main cycles that could affect the ecology. The Nitrogen cycle, and the CO2 cycle. \n\nPlants use Carbondioxide for photosynthesis and give off oxygen.. where animals use oxygen and give off carbondioxide. any instability in this cycle would have detrimental effects.\n\nNitrogen cycle.. ammonia based compounds in the soil mostly from animal waste are converted into nitrites and nitrates by specific bacteria  so that they are absorbed by the plants...without animals, there would be a major imbalance.

Not necessarily true.  It depends on if this park is in the city or not, and whether or not it is a state or national park.  Call the township park & recreation dept for the township it is in and they can answer all your questions.  If this park is a national park, you simply won't be allowed to have it at all.

We let a forest fire free burn and we learned how fast a ecosystem can regrow itself.\nRe-populated it with wolves. Now wolf hunting is allowed to control the population.\nHighly studied area. (Super Volcanoes, geysers, wildlife)\nThe park service tries to limit the impact of humans.

The squirrels in my yard bury nuts at random and apparently forget where they buried them. The buried nuts are open game for all the squirrels. Anywhere they find soft dirt (like around my bedding plants) they will dig, just in case that's a spot where some other squirrel buried a nut.  In the spring, they dig all over they place looking for something to eat.  They like to munch on green stuff, such as dandelion leaves and will raid trash cans if they aren't well secured.  We call them tree-rats around our house.  One thing they do, though, that is cute is when they bury a nut, they scrape the dirt back into the hole and then tamp it down with their front paws.\n\nHere in Washington, they don't hibernate, they are active all winter.

The answer is none.\nSee, boy squirrels CAN chase tails, they don't do it though as they're all too obsessed with burying their nuts in places they then forget about.
