An empty field left undisturbed for long enough will inevitably turn into a forest, given enough time. Nature will fill empty, barren or disturbed ground with plants which quickly stabilise and build the soil, to prepare the ground for progressively larger plants, until the area is filled with trees, and many layers of understory plants beneath them. Remote sensing. Acquisition of information at a significant distance from the subject Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation, especially the Earth.

Remote sensing

Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines (for example, hydrology, ecology, meteorology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications. In current usage, the term "remote sensing" generally refers to the use of satellite or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). Overview[edit] Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas. Sans titre. What’s in dirt anyway?

Temperate Deciduous Forest

Deciduous Forest. Deciduous biomes are located primarily in the eastern half of the United States, Canada, Europe, parts of Russia, China, and Japan.

Climate The average temperature of the forest is about 50 degrees F. Importance of Tree Trimming. Earth Floor: Biomes. Deciduous Forest The mid-latitude deciduous forest biome is located between the polar regions and the tropics.

Earth Floor: Biomes

Because of its location, air masses from both the cold polar region and the warm tropical region contribute to the changes of climate in this biome. Forest certification: a small step towards sustainability. It can be hard to know whether the forest products you buy have been produced sustainably.

Forest certification: a small step towards sustainability

Forestry certifications were established to give a bit more certainty, but what do they really mean? When you buy a certified product, are you necessarily helping the environment? A short history of certification The two international forestry certifications - Forest Stewardship Council (FSC) and Program for the Endorsement of Forest Certifications (PEFC) - have had an interesting history over the past 20 years. There are often clouded interpretations and miss-interpretations of how each came about. According to environmental NGOs, governments failed to agree on how to address rapid deforestation, mostly in the tropics.

Symbiosis: A Surprising Tale of Species Cooperation - David Gonzales. Temperate Coniferous Forest. Temperate evergreen forests are found predominantly in areas with warm summers and cool winters, and vary enormously in their kinds of plant life.

In some, needleleaf trees dominate, while others are home primarily to broadleaf evergreen trees or a mix of both tree types. Temperate evergreen forests are common in the coastal areas of regions that have mild winters and heavy rainfall, or inland in drier climates or montane areas. Global warming. Global warming describes the current rise in the average temperature of Earth’s air and oceans. Global warming is often described as the most recent example of climate change. Earth’s climate has changed many times. Our planet has gone through multiple ice ages, in which ice sheets and glaciers covered large portions of the Earth.

It has also gone through warm periods when temperatures were higher than they are today. Past changes in Earth’s temperature happened very slowly, over hundreds of thousands of years.
