We tend to think that we can deal with the challenge of carbon dioxide in the atmosphere by planting more vegetation,
the local climate, vegetation, patterns of rain and snowfall, and mountain topography are deemed all natural assets that create a new perspective
 Rather than relying on assumptions about the role of urban vegetation in improving the environment and health,
the design team Koetter Kim suggested cooling towers could be replaced by recirculating water through green space such as wetlands, walls of vegetation, agriculture and fountains.
There are no more infertile stretches of asphalt sprawled over our urban rooftops but an expanse of vegetation
archaeologists Arlen and Diane Chase slogged through the thick undergrowth in the west of Belize in search of an ancient city
and study forests and other vegetation. He suggested they give it a go. So, in 2009, the pair packed away their machetes
particularly those covered in dense vegetation. The technology has been used in a variety of ways over the last two decades,
Crucially, some of the laser light is also able to penetrate vegetation. So, in the case of areas covered in a forest canopy
as we convert vast tracts of wild vegetation to agricultural or grazing areas, for example. Fishing on an industrial scale to provide for billions has altered dramatically marine diversity.
however, inappropriate flooding of vegetation can cause greenhouse gas emissions and poison the water for fish.
The rotting vegetation recycles nutrients and attracts microorganisms, worms and insects, which help maintain soil fertility
You can see the effects of global warming in a new high-resolution map that shows carbon locked up in tropical forest vegetation
Ultra high tech farms of the future will generate exotic half-plant, half-animal vegetation as well as crystalline plants, air plants,
and optimize their operating capacities to produce energy and water and by proxy vegetation. This sense of collaboration is echoed in the team of people behind the proposal:
The prevailing opinion is that forest fires can be sparked by intense sunlight focused by water drops on dried-out vegetation.
if water droplets are caught on dried-out vegetation, Horvath and colleagues added a note of caution:
The Dutch researchers say they plan to build a commercial-sized building in The netherlands of 1, 300 square meters (14,000 sq. feet), with four separate levels of vegetation by the end of this year.
#said Mark Underwood, a Michigan lawn care specialist. Weve never experienced anything like this.##The herbicide is suspected of killing Norway spruce and white pine trees en mass all over the country.
but the steady precipitation results in lush vegetation, earning Seattle the nickname the Emerald City#and serving up plenty of locally grown goodness.
back yard and indoor vegetation has become a new experience. The health benefits go beyond just small amounts of food, to improving air quality, the natural environment and providing healthy exercise.
The 50 species (of bumblebees) in the United states are associated traditionally with prairies and with high alpine vegetations#
If planted on the ground the total vegetation would cover an area of 10,000 square meters.
#Researchers calculated projected levels of surface ozone concentration, a powerful air pollutant that is not only harmful to human health (particularly to the respiratory system) but also damages vegetation by damaging plant cells and inhibiting
Designers have come up with ideas that cover the walls with vegetation and give them an all new life.
you will see that the area around that watering point looks as brown and devoid of vegetation as the top of this table,
you can encompass a soil type, a vegetation situation, a poisonous plant, or whatever, much better than you can
For us, just the thought of looking out the window to see the shrubbery sneaking across the lawn on robotic legs is enough to have us scrambling for our wallets.
and chomping on vegetation hunter-gatherers are thought to have walked 9 or more kilometers (5. 6 miles) every day Lieberman said.
The team plans to return to the Mendenhall Glacier to dig through sediment in search of pine needles associated with the trees along with other vegetation.
#Arctic Going Green from Warming, Study Finds Large swaths of the Arctic tundra will be warm enough to support lush vegetation
About half the areas will see vegetation change and areas currently populated by shrubs may find woody trees taking their place.
To find out exactly how much greening Arctic warming would bring the team used a model that projected how temperature changes would affect snow cover vegetation and the increased evaporation and transpiration from plants in the Arctic.
and track down other food sources from vegetation and grasses. The study reveals something interesting about the way scientists might operate.
and dries out before native vegetation does a continuous carpet of fuel for fires. An NSF-funded study conducted by Balch
In addition cheatgrass burned twice as frequently as any other vegetation. The Heat is On Another factor promoting increased wildfires in the western U s. is climate change
In fact fires that people intentionally start to clear land of vegetation currently contribute up to one-fifth of human-caused increases in carbon dioxide emissions according to a study conducted by Balch and other scientists.

or decaying vegetation do the work for them. The chicks when they finally hatch are quite mature;
and vegetation zones begin to shift northward within this century as predicated by climate scientists vineyards may face more erratic crop qualities;
since overgrazing strips the Earth of vegetation. And in Africa where he was working to set up national parks in the 1950s Savory thought elephants were also to blame for the land's deterioration.
and vegetation developed alongside very large numbers of grazing animals which traveled in packs were constantly moving sometimes quite frantically
and intentionally set fires that altered the vegetation and created a parklike landscape he said.
because a century of fire suppression and replanting has left forests overgrown with thick underbrush
Many areas are too steep to reach with bulldozers to rip out trees said Scott Conway a vegetation management officer with the U s. Forest Service in the Tahoe National Forest who is also involved with the project.
Thanks to work by Keeley and his colleagues researchers now know techniques that work for firefighters in the Colorado mountains won't help Californians battling wind-driven wildfires in the chaparral.
Southwestern Wildfires Seen from Space Don't burn chaparral In California as the population sprawls the fires grow.
To protect homes local fire managers frequently set California's chaparral-covered hills ablaze. But the decades spent earnestly masticating (mechanically removing potential fire fuel) devil-red manzanitas with trunks as thick as thighs
and the repeated prescribed burns replaced native chaparral with incendiary invasive species like cheatgrass according to the USGS. The decades of effort were for naught finds a series of recent studies from the USGS and colleagues at the Conservation
But chaparral isn't forest. It's a dense carpet of woody shrubs: chamise ceonothus and other plants that cling to steep canyons and ridges.
Unlike Western forests coastal chaparral and sage scrub may burn only once every 100 years and the inland ridges every 30 years.
When chaparral erupts in flames every few years native species burn through their energy stores
and seed stock trying to recover said Rick Halsey director of the nonprofit California Chaparral Institute which advocates for preserving chaparral.
and said the natural fire regime in chaparral is anywhere from 50 to 150 years not 10 to 15 years.
Fighting fires with fuel Clearing chaparral for firebreaks a gap meant to slow spreading flames also does little to help fire fighters battle the chaotic infernos driven by California's Santa ana winds Fotheringham told Ouramazingplanet.
and in cleared chaparral act as kindling for flying embers said Fotheringham. The whirling winds carry embers as far as a mile in front of the actual wildfire.
when houses burn blown embers are at fault not trees or chaparral. The primary spread of fire where we lose houses under wind-driven conditions is from embers Fotheringham said.
With green vegetation you have to drive off the moisture before it will ignite. I got to looking around my yard and
A lot of what we have for urban vegetation is deciduous so in the fall the Santa ana wind-driven fires coincide with leaf drop.
and landscaping with fire-resistant vegetation will go a long way toward reducing future fire damage he said. We see the potential for improvements that can have as much impact as
(because there is less vegetation to suck up precipitation) as well as released additional carbon and nitrogen from dead decaying trees.
Burrowers Funnel spiders pick moist and sheltered places to build their burrows like under rocks or logs or in shrubbery.
Prescribed burns remove the undergrowth and dead matter on the forest floor that can fuel a ground fire.
which meant there was less underbrush and fewer small trees to fuel the fire once it reached Yosemite so the blaze slowed.
and 24 percent happened in areas of thick vegetation cover. Although trees and shrubs may offer cheetahs better means to stalk prey the researchers did not find significant differences in the speed
but one male cheetah who frequently hunted in areas with thicker vegetation occasionally hunted warthogs Wilson said.
Understanding the vegetation in the area during that time helped the scientists piece together more clues about the precipitation and climate.
Those tortoises kept Madagascar's unique ecosystem in check by munching on low-lying foliage trampling vegetation and dispersing large seeds from native trees like the baobab.
With their demise the composition of Madagascar's ecosystems changed shrubs and vegetation clogged the forest floor
The chemicals are sprayed also directly on locusts instead of on vegetation or the ground are used only in small quantities
If people become convinced that a gold-laden city is hiding in the Honduran rain forest it could encourage looting he said damaging the real archaeological sites that no doubt lurk among the tropical vegetation.
Even so dense vegetation now veils much of the complex impenetrable to conventional remote-sensing techniques the researchers noted.
Lidar provides an unparalleled ability to penetrate dense vegetation cover and map archaeological remains on the forest floor the researchers wrote in an accepted manuscript submitted to the journal Proceedings of the National Academy of Sciences.
When the Lidar data revealed the elevation beneath Phnom Kulen's dense vegetation the researchers knew they had found something big.
The vegetation gap expands as the competition ensues and the grass-free zone becomes a reservoir for nutrients and water.
Scientists have proposed also previously that fairy circles are an example of a self-organizing vegetation pattern
In 2008 researchers developed a mathematical model showing the vegetation patterning of fairy circles could depend on water availability.
and fertilizing the circles should cause them to close up with vegetation Tschinkel said. Follow Joseph Castro on Twitter.
since in India where peacocks are typically found thick vegetation could obscure everything except the top part of the males'display of feathers.
As for vegetation it was limited fairly in many areas. There were some scattered conifers including pines cypress and yews along with some broadleaf trees such as beeches and oaks.
Even around the tropics where vegetation is plentiful humans have been cooking as long as humans have been human at least 200000 years and likely longer in our hominid form.
'Nuked'California's enormous Rim Fire had a devastating effect on soils and vegetation according to Forest Service ecologists.
A full 60 square miles (155 square kilometers) burned so severely that all vegetation died a senior wildland ecologist told the Associated press. In other words it's nuked ecologist Jay Miller said.
Scrubs and grasses were mapped also extensively so well in fact that researchers today know how dense the vegetation on the forest floor used to be.
Despite the thinning process the research site still contains a fair amount of ground shrubbery that would aid in fueling the Rim fire
Different types of vegetation reflect different wavelengths of light often in ways that the naked eye can't detect.
wildfires and desertification release carbon stored in vegetation; and melting permafrost allows for the decomposition of peat bogs and the melting of methane hydrates releasing methane into the atmosphere.
and store carbon in the soil or vegetation at higher amounts than do buildings or roads.
To shed light on this mystery a team of investigators have reconstructed past changes in vegetation by looking at ancient sediment from the Murray Canyons Group region offshore southern Australia.
This molecule is generated exclusively during the burning of land vegetation so its presence would bolster the idea that humans changed the landscape with fire.
much as they do today making up 60 to 70 percent of the vegetation there. However by 43000 years ago C4 plants made up only 40 percent of the vegetation there.
There was a matching rise in C3 plants that lasted for about 5000 years. Which came first?
This in turn led more fire-prone vegetation to build up in the Australian landscape the researchers said.
In 150000 years of climate change in southeastern Australia lots of changes in the vegetation took place
In some regions the climate will become more arid resulting in less vegetation in forests with the end result being less fuel.
Changing temperatures might also influence what vegetation returns after a fire some forests may never come back.
although it may have to do with changes in forest management that have allowed dense underbrush to grow as well as increased urban development.
Living and dead vegetation make up the fuel that burns in a wildland fire. Warmer and drier conditions make present-day fuels such as forests more likely to burn
Also the total amount of vegetation isn't the only important factor because many species will shift ranges.
Feedbacks between disturbances such as fire and the uncertainty of what vegetation will come in afterwards compound the difficulty of predicting future patterns.
Researchers attempting the difficult task of linking models of climate vegetation and fire at global scales an exercise called pyrogeography are finding not only high variability between models but sometimes not even agreement on overall trends.
Third when wildland managers compare alternative management options they should routinely apply models linking climate vegetation and fire.
they eat both meat and vegetation. Typical meals for a wolverine include large game like caribou moose and mountain goats;
new life into riverbank vegetation. Because the floods rejuvenated these riverbank zones conservationists were hopeful that the wetlands could be restored.
and to enhance the delta's natural vegetation and wildlife Flessa told Livescience. Research teams from agencies universities
For instance researchers on the ground will track where the water flows on the surface examine how it infiltrates the groundwater and monitor vegetation and bird life.
In addition to field work we will be using satellite images to study the response of vegetation in the following four years Flessa said.
If you're a hiker know what type of vegetation plants and trees are found in the areas you'll be heading into.
And far from living in a monotonous grassland the mega-beasts inhabited a colorful Arctic landscape filled with flowering plants and diverse vegetation the study researchers found.
It makes us rethink how the vegetation looked and how those animals thrived on the landscape.
But recreations of the ancient Arctic vegetation relied on fossilized pollen found in permafrost or frozen soil.
The DNA analysis showed that the Arctic at the time had varied a landscape filled with wildflowers grasses and other vegetation.
but they are actually omnivores they eat meat and vegetation. They eat small game such as rodents rabbits fish and frogs and larger game like deer.
Stunning Photos of the Amazon According to MODIS algorithms an area is covered likely in green vegetation
That makes it appear very green according to satellite vegetation algorithms though in reality the forest canopy hasn't actually greened the study found.
In fact the peat soils in Southeast asia store as much carbon as all aboveground vegetation in the Amazon.
The Native americans who once hunted this region lit fires to burn off dead vegetation encouraging new growth that attracted bison and other large game.
About 80 percent of prairie vegetation is grass (40 to 60 species) with the remainder made up of more than 300 species of wildflowers plus trees scrubs and lichens according to Live Science's Our Amazing Planet.

just as strong as climate in controlling where vegetation does and doesn't appear in the Sierra nevada said Jesse Hahm a geologist at the University of Wyoming
To determine that tree-ring data was an accurate representation of grassland productivity the researchers compared their tree-rings to satellite data of vegetation covering Mongolia between 1980 and 2010.
The technique can only be applied to open flammable vegetation. In dense eucalypt forests (such as wet sclerophyll forests) fuel-reduction burning is impractical because of the risk of uncontrollable fires sustained by heavy fuel loads that only become flammable in dry conditions.
and thinning vegetation including burning the debris in specially designed portable furnaces that have low smoke emissions.

There are early hints that a vegetation threshold may exist Varner said meaning that pikas need a certain number of plants to maintain a population.
Amazing'Fairy circles'of the Namib desert Fairy circles are barren patches typically surrounded by a ring of thriving vegetation.
But over the years vegetation thins in a self-regulating process so that mature trees have enough space
This means they only eat vegetation typically grasses leaves and shoots of plants. According to Endangered Wildlife and Plants of the World Volume 5 (Marshall Cavendish Corp. 2001) some gazelles can live their entire lives
Vegetation is gone in many places leaving bare soil #which contributes to dust storms he said. In Texas 240 counties were designated primary natural disaster areas#by the U s. Department of agriculture in April along with several counties in Oklahoma.
they only eat vegetation such as shrubs bushes and grasses. Grazing accounts for a significant part of their eating habits.
This type of pervasive vegetation dominates forests and makes up 90 percent of all plant life on land.
which means that they can eat both meat and vegetation. Most parrots eat a diet that contains nuts flowers fruit buds seeds and insects.
and kakapos chew on vegetation and drink the juices. Parrots are like most other birds
Our findings however indicate a history of disturbances to vegetation. Earth's Plant life from Space in Photos Hunt added that these changes in vegetation do not coincide with any known period of climate change
but rather have been brought about by the actions of people. Ancient people of Southeast asia didn't exactly replace their tropical forests with rows of cereal crops
This indicates that the people who inhabited the land intentionally cleared it of forest vegetation and planted sources of food in its place.
and bare and deserted no vegetation I have to constantly buy hay and grain to keep the sheep fed#Dixon said looking at the land around her trailer.
Sand dunes are stabilized normally by vegetation but much of that vegetation has died amid the drought allowing the dunes to spread jeopardizing the rangeland and even homes.
Some people in the southwest quadrant of the Navajo Nation may be forced to relocate because of encroaching sand dunes according to Redsteer s research.

and so eat only vegetation. Their favorite foods are grass and herbs but water buffalo will also eat aquatic plants.
which grow farther apart than rainforest vegetation. As a result, streamflow has dropped and wells have dried up in many villages in Xishuangbanna.
The vegetation in the region, dominated by bushes and tall eucalyptus trees, burns extremely well when dry.
Most trees and tall vegetation can survive normal bushfires, and smaller, more frequent fires reduce the risk of a catastrophic blaze.
Increased fire frequency could lead to vegetation changes that would reduce plant growth, decreasing the amount of carbon that plants remove from the atmosphere further exacerbating greenhouse warming by carbon dioxide.
The idea is to deliberately set the vegetation on fire from time to time, without letting fires get too large.
Ecologists are still assessing the best time of year for setting different types of vegetation on fire, to find the best strategy that causes the least damage to plants.
There have been hints of vegetation changes all along, but this is the first time all these techniques have come ogether for southern Peru.
as vegetation creeps northward, it will accelerate warming trends already in place. Higher surface temperatures in recent decades are already making it easier for trees to grow farther north.
But when the vegetation moves in, there will be an amplification of the warming, says Inez Fung, an atmospheric physicist at the University of California, Berkeley.
Because vegetation is darker than bare land, it has lower albedo or reflectiveness so absorbs more of the Sun's energy

The group used satellite data to identify the start, end and length of the growing season for the meadow and steppe vegetation of the Tibetan Plateau between 1982 and 2006,
The net effect was a shortening of the growing season by about one month for steppe plants and three weeks for meadow vegetation.
vegetation and peat land have burned across the Russian Federation since the fires began in June.
just as humans plant seeds in areas with naturally growing vegetation. But farming has its costs.
Mangroves and salt-marsh vegetation similarly accumulate carbon and when they decompose their carbon is locked away in watery, peaty sediments for millennia.
if carbon from cleared vegetation were released back into the atmosphere. But that study underestimated the amount of carbon-12 taken up by peatlands
