The drier the air and lower humidity, the faster the diffusion and transpiration. 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,ft, 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.
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. As discussed above, humidity impacts on plant growth through its effects on transpiration. At higher altitudes the air is often drier naturally, especially the higher you go. Unless a low-cloud is passing over which is essentially the highest humidity air you can get. This is because of the high water content draining in the soil from the moors above down to us, the location of our hill range and amount of rainfall we receive.
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. In our garden I can confirm that it indeed does rain a lot!
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. All of these factors will have varying degrees of influence on plant growth that differs through the seasons and with different weather conditions. Your email address will not be published.

The sub-alpine extends downward from about 11, feet to 9, 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.
Although altitude is always at work, other factors contribute to its effect on plant life. Latitude, too, plays a part. The tree line does not occur at the same altitude in all parts of the world. Coffee crops grow at altitudes of up to 7, feet in the Bolivian Andes, where peaks soar to 17, feet.
Coffee grown at high altitudes is well known for excellent flavor. In the mid to high temperate zones in the northern hemisphere, tree line occurs at 12, feet or less. According to the Colorado State University Extension, grapes grown at elevations of 4, feet receive more direct sunlight and are of better quality than ones grown at lower elevations.
Indirectly, altitude plays a part in pollination. If the altitude is inhospitable to the bees or other insects that pollinate the blossoms of fruit trees and plants, crops can suffer. The long-tongued bee fly common to elevations between 4, and 5, feet has a profound effect on the pollination of nectar-producing flowers, but the bee fly cannot survive outside its habitat, so again, altitude is in control.
Wind, though, plays a part with altitude in the limits set for successful pollination. What do you mean by vegetation? Use the word vegetation to refer to all plants and trees collectively, typically those in a specific region. Vegetation, as well as meaning all plant growth, can refer to the growth process of a plant.
The lettuce you planted a couple weeks ago is at an early stage of vegetation. At what altitude does vegetation stop growing? In Mexico, for example, treeline occurs somewhere around 13, feet, whereas farther north, in the Tetons, for instance, it occurs lower, at approximately 10, feet.
Again, it's a ragged line that may vary by hundreds of feet on any mountain, depending largely on shelter and exposure.
How does vegetation change on a mountain? Alpine vegetation had a trend to increase and expand to higher altitudes with the climate change in the past 40 years. The variation appears to be associated with an increase in mean temperature of 0. What plants grow at high altitudes? Perennials that are native to high-elevation areas in Western states include columbine Aquilegia spp , yarrow Achillea millefolium , Butterfly flower Ascelpias incarnata , coreopsis Coreopsis grandiflora , Echinacea Echinacea purpurea and gaillardia Gaillardia aristata.
What is the special features of mountain vegetation? What environmental factors might affect a plant growing on a mountain top? Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition.
Why does the natural vegetation in the Himalayan mountain change with altitude? In the Himalaya mountains, the vegetation changes according to the altitude because the temperature and rainfall decrease with height. Can you farm above feet?
The highest-grown coffees in Costa Rica might come from farms that are 4, feet above sea level, while Ethiopia has farms that sit at 6, feet. Generally speaking, though, an altitude above 4, feet is considered high enough to produce the growing conditions that create dense, desirable beans.
