How does altitude affect plant life?
As the altitude increases, climate changes. The air becomes colder and drier, affecting plant life accordingly. Many plants have adapted strategies for surviving at high altitudes, and though other factors are contributors, directly or indirectly, altitude plays a part in the development and survival of all plant life.
How does climate affect vegetation development?
Climate plays a large role in what types of vegetation can grow in a certain area. In higher altitudes, the wind and coldness become a large factor in vegetation development. The United States Department of Agriculture outlines particular zones of high elevation in which plant life can withstand extremely low temperatures.
How does elevation affect climate?
As temperature decreases with elevation, the climate conditions change. In the northern hemisphere’s middle latitudes, the climate tends to get more extreme as elevation increases. As elevation increases, it is more likely that a region will have both ice caps and tundra.
Why don't trees grow well at high altitudes?
Smaller plants that hug the ground don't suffer from the wind as much. Even the evergreen trees at high altitudes are smaller. Deciduous tree leaves would lose too much water to allow them to survive at the highest altitudes.

Does elevation change vegetation?
Slope and elevation had an impact on the VFC; the areas with large vegetation change are mainly distributed in slopes <20° and elevation of 3000–5000 m. For elevation above 3000–4000 m, the response of the VFC to precipitation and temperature was the strongest.
In what ways does altitude affect the distribution of vegetation?
Elevation can influence the form and amount of sunlight that plants obtain, the amount of water that plants can absorb and the nutrients available in the soil. As a result, some plants thrive very well at high elevations, while others may only grow at higher or lower elevations.
How does elevation affect the environment?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.”
How does latitude and altitude change vegetation?
The vegetation generally decreases with the increasing altitude and the sun facing side of a mountain also has better vegetation growth. Thus the Latitude and altitude determine the climatic conditions and insolation of a region which in turn determine the vegetation of a region.
Why do the vegetation cover decreases with increasing altitude?
Plants need carbon dioxide to grow, and lower air density and atmospheric pressure at high altitude produces lower carbon dioxide levels and a slower transpiration rate. Slow transpiration and limited carbon dioxide slow down the rate of photosynthesis and growth.
How does altitude affect vegetation and wildlife in brief?
The higher we go ,the colder it gets. Due to this reason only plants and animals adapted to living in cold areas can survive. This is why altitude affects wildlife and vegetation.
What happens when elevation increases?
As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude.
What is the relationship between elevation and climate?
Usually, as elevation increases, the weather gets colder and the climate becomes harsher (more intense weathering: windier and colder). There is also less air as elevation increases. As elevation decreases on land that most live on, the climate gets warmer as well as more humid.
How do elevation and latitude affect climate?
Temperature usually decreases by 1°C for every 100 metres in altitude. Distance from the sea - Oceans heat up and cool down much more slowly than land. This means that coastal locations tend to be cooler in summer and warmer in winter than places inland at the same latitude and altitude.
How latitude and altitude affect which plants grow in an area?
Altitude and Temperatures Plants are well adapted for where they live. Plants that live at higher altitudes have to adapt to colder temperatures. Because the summer season at higher altitudes is so short, annuals have a big advantage, growing, flowering and setting seed in a few weeks.
How does altitude affect forests?
FORESTS CHANGE WITH ALTITUDE Environmental conditions vary with altitude – temperature, soil type, rainfall, humidity – and this influences what grows there. “When you walk from the lowland to the high altitude, some species disappear, because they are not adapted to those conditions,” Gonmadje says.
How does altitude affect soil formation?
With increasing elevation, pH, base saturation, exchangeable potassium, and fine silt-sized particles decrease significantly, while organic matter, the C/N ratio, soil aggregate stability, water repellency and coarse sand-sized particles increase significantly.
How does altitude affect the distribution of organisms?
Organisms can live at high altitude, either on land, in water, or while flying. Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.
How does altitude affect species distribution?
The researchers found that plant biodiversity initially increases with altitude, until it reaches a diversity peak at around 1 300 to 1 800 m, after which point it decreases with altitude.
How latitude and altitude affect which plants grow in an area?
Altitude and Temperatures Plants are well adapted for where they live. Plants that live at higher altitudes have to adapt to colder temperatures. Because the summer season at higher altitudes is so short, annuals have a big advantage, growing, flowering and setting seed in a few weeks.
What is the impact of latitude and altitude on the distribution of biodiversity?
Biodiversity varies with a change in altitude or latitude. The diversity increases as we move from high to low altitudes (i.e., from poles to equator).

Crop production is concerned with the exploitation of plant morphological (or structural) and plant physiological (or functional) responses with a soil & atmospheric environment to produce a high yield per unit area of land.
How does altitude affect plant life?
From sea level to timberline and beyond, plant life is influenced by altitude. As the altitude increases, climate changes. The air becomes colder and drier, affecting plant life accordingly. Though other factors are contributors, directly or indirectly, altitude plays a part in the development and survival of all plant life.
Why do trees not grow?
Because of the limits set by altitude, trees do not grow beyond the timberline (tree line). At that altitude air pressure is less and carbon dioxide is greatly reduced. Carbon is essential to the survival of all plant life. Near the timberline, trees become smaller, scattered. Growth becomes stunted or distorted.
Why are the leaves of a scrub tree smaller?
Leaves are smaller, with less surface area to absorb the energy-giving carbon dioxide they need. Only scrub, a few hardy wildflowers, lichens and moss will venture beyond the tree line and into the alpine region above. Scrub growth is small. It sprawls close to the ground for protection from the dry, alpine air.
Do horses graze in high meadows?
According to a USDA report, a three-year study shows that forage in the high meadows after pack horses are picketed there to graze is slower to recover after grazing than in meadows at lower elevations. Whether or how this significantly relates to global crop productivity has not been established.
Why do plants grow at higher elevations?
Being higher generally means lower air temperatures, due to wind and air movement of course, but also largely because of air pressure. The molecules in air bump into each other creating some warmth but with thinner air at higher elevations there are fewer molecules. Fewer air molecules means less bumping and friction to create warmth. Temperature impacts plants because they grow best at certain temperatures. Exactly what temperature growth is fastest at will depend on the plant itself, and many are adapted to colder temperatures. When temperatures go too high, this can also slow plant growth as the plant effectively shuts down to conserve moisture. But let’s say, as an example, plant growth is optimum between 10 – 25C, generally the higher the temperature in the range, with good light, nutrients, CO2 levels and water, a plant will grow at its fastest. E.g. a plant at 25C can grow faster than one at 20C if all other factors are the same. So even a slight drop in temperature due to altitude can cause plant growth to be slower than a plant lower down the hill and a few degrees warmer.
How does higher altitude affect light?
Being higher impacts light in a number of ways. The intensity of light will be stronger due to the thinner atmosphere, and light radiation levels slightly higher too. Thanks to the height of our hill, we also have more hours of sunlight than lower down in the valley where the sun sets earlier due to the angles, particularly in winter when the sun is lower in the sky. Higher light levels at our altitude will generally increase photosynthesis resulting in strong plant growth. Go higher and plants will need more protection from the scorching sun. Naturally plants have evolved adaptations to this such as silver or lighter leaves to reflect the light and hairs to protect the leaf.
Why does it rain a lot at high altitude?
The higher your altitude, generally the more precipitation there is because the atmosphere can’t hold as much moisture, releasing it as rainfall. If you’re on a hill or mountain, the side you’re situated on will have an effect too because the side facing the prevailing wind will receive most precipitation. In our garden I can confirm that it indeed does rain a lot! I’ve found it interesting just how much water there is, with high levels of water retained in the ground and water coming from higher up the hill, it means I barely have to water at all. There is also a lot of dew in the mornings because of the water in the ground creating high humidity and because of the plants themselves releasing excess water through the edges of their leaves, a process called guttation. Dew here can be so heavy it’s like there’s been a heavy downpour when it hasn’t rained for weeks.
How does air pressure affect plants?
The higher your garden’s elevation, the lower the air pressure. Air pressure has an effect on plant growth in a number of ways. Lower air pressure has less carbon dioxide, which plants need to grow, and it also means a slower rate of transpiration. Undoubtedly this will slow the rate of photosynthesis and plant growth, something I’ve seen happening in our new garden. Certain plants I’m very familiar with such as Cosmos and Ammi are at least a month or more behind gardens lower down. At the start of spring when tree leaf growth was slower, this could have been put down to temperature but since the start of summer, temperatures haven’t been that different – the biggest difference is air pressure. The plants are growing in a sheltered enclosed area of the garden where wind is less of a factor. You can choose plants that have evolved to life at a higher altitude and even collect seeds from plants like peas and beans to gradually breed plants that show stronger growth in these conditions. Air pressure will ultimately have an effect on the size of the plant in conjunction with other factors below. The higher a plant, the more compact it will grow, though we’re unlikely to notice the difference at 300m, and size is also influenced by factors such as nutrients available, and our soil is extremely fertile.
Why is my garden high up?
Gardening high up usually (but not always) means you’re likely to be on a slope of some kind. This probably means the garden has good drainage as water runs downhill. This can be a problem for some because in summer, the soil can dry out completely very quickly. Less water means slower plant growth. However, this isn’t a problem in our garden because of the high number of natural springs, water drainage from above and retention in soils.
How does wind affect plants?
The air around plants will have varying levels of humidity and this impacts how much water is lost from the plant. Plants absorb water through their roots which is transported up to their leaves via the process of transpiration where water evaporates from the surfaces of their leaves, they do this to transport nutrients through the plant for photosynthesis. Depending on how humid the air is, the plant will speed up or slow down transpiration because of diffusion. Diffusion is the process of molecules moving from an area of high concentration of those molecules to one of low concentration. When you spray perfume at one end of a room, diffusion carries it to the other end. In a plant’s case, water molecules evaporating into the oxygen and carbon dioxide molecules of air. If air has higher humidity with higher concentrations of water, the slower the diffusion from the leaf. The drier the air and lower humidity, the faster the diffusion and transpiration. When it’s windy, humidity decreases and water is drawn from the plant faster – unless of course it’s a high humidity rainy day. Winds can cause transpiration to happen much faster which is noticeable most in pot plants because they can dry out very quickly on windy days. In our new garden at 1,000ft, wind will be having an effect on plants. On warmer days sometimes causing them to close their pores to slow transpiration and growth. In addition to water effects, wind will make plants stockier with increased rocking, causing them to react with shorter, stronger stems. You see this sometimes with trees bonsai’d in exposed spots from wind. Some plants, such as garden alpines, have also evolved to protect from wind, and leaf hairs help keep humidity in around the leaf surface by shielding from wind.
Why are plants at higher altitudes more susceptible to water loss?
For plants that live at higher altitudes, preventing water loss is a big challenge. Higher altitudes have lower humidity levels, meaning that water loss is naturally greater and there is less rainfall meaning there is less water available for replacement. In addition, the wind at higher altitudes is a factor.
How do high altitude plants help with water loss?
Successful high-altitude plants have developed strategies to help them reduce water loss, such as having a waxy coating on the surface of their leaves, called suberin, and having their stomata in small divots of the leaf's surface to reduce wind damage.
Why does the temperature at the equator change?
The change of season causes the temperatures further from the equator to change greatly. In some areas, the temperature can reach 100 degrees Fahrenheit in the summer and minus 20 degrees Fahrenheit in the winter. The temperature at the equator also changes during the year because of rainy seasons that cool the land temperatures but not ...
How do stomata help plants?
Stomata are the pores in the plant's surface that allows it to breathe and transport minerals from the roots to the leaves. Another way to reduce water loss is to stay small. Smaller plants that hug the ground don't suffer from the wind as much. Even the evergreen trees at high altitudes are smaller.
Why can't deciduous trees survive in high altitudes?
Deciduous trees can't survive at high altitudes because the summer is too short to allow them to grow leaves and store enough energy to survive the longer winters.
Why does the Earth have an atmosphere?
In addition, the Earth has an atmosphere that buffers the heat of the sun's rays. Sunlight has to travel further through the atmosphere at the poles than it does at the equator because of the angle of incidence of the curved surface of the earth. Sunlight loses energy bouncing off the molecules in the atmosphere, ...
Why do plants need less water during the day?
With higher temperatures, plants have adapted to using less water during the day or they would wilt in the higher heats. In northern climates, plants have developed strategies to maximize daylight hours for photosynthesis and using nighttime to respire.
How does elevation affect plants?
Elevation plays a large role in the health and growth of plants. Elevation may affect the type and amount of sunlight that plants receive, the amount of water that plants can absorb and the nutrients that are available in the soil. As a result, certain plants grow very well in high elevations, whereas others can only grow in middle ...
What is the difference between higher elevation and lower elevation plants?
Plants in higher elevations typically receive more direct sunlight than plants of lower elevations . In addition, these plants receive a special type of sunlight, which has short-wave radiation. Whereas this poses an advantage for higher elevation plants because they receive more sunlight that they need to grow, it can also damage the plants if the short-wave radiation exceeds a certain amount. Lower elevation plants typically require less sunlight, and they are safer from many short-wave radiation waves, which do not reach farther down into lower elevation regions of Earth's surface.
Why do high elevations get more precipitation?
In broad highlands, this may simply be because the generally cooler air has less capacity to hold moisture, generating clouds and precipitation more readily . But hills and mountains also actively induce precipitation through what’s called the orographic effect : Air shoved upwards by terrain cools to condensation point, resulting in cloud formation and precipitation.
How do plants adapt to UV B?
Studies suggest high-elevation plants have evolved some resistance to their environment’s greater UV-B radiation through adaptations such as thicker, smaller leaves and an increased concentration of ultraviolet-absorbing pigments such as flavonoids in their tissues.
Why is carbon dioxide less available in alpine plants?
There’s inherently less carbon dioxide available to alpine plants due to the lower air density and atmospheric pressure at altitude. Yet evidence suggests that reduced carbon dioxide isn’t an important limiting factor for plants at high elevations. One reason may be that diffusion rates of gases increase with lower atmospheric pressure, allowing for easier uptake by plants and perhaps compensating for carbon dioxide’s lower partial pressure and availability.
Can snowdrifts limit the growing season?
But lingering snowdrifts and snowfields that persist well into late spring or early summer – or longer – can also limit the growing season at a particular site, preventing most plants from gaining a foothold.
Do high elevations have higher wind speeds?
Many high-elevation areas, particularly mountains, experience significantly higher windspeeds than lower elevations. Higher-altitude winds not slowed by the frictional drag of the lower ground surface can hit high hills and mountains rising into their airstream. At upper elevations, furthermore, low-growing vegetation such as stunted tree scrub and tundra doesn’t disrupt blowing wind to the same degree as taller vegetation lower down.
