Afforestation near Lake Argyle
The presence of a sufficiently large artificial reservoir capable of maintaining the level of groundwater and ensuring daily maintenance of air humidity. This allows you to abandon the artificial watering of seedlings, which creates a more natural survival rate of young trees.
The volume of the annual flow of all rivers into the world ocean is about forty three thousand cubic kilometers. This, if I may say so, is excess water that has not been evaporated and transported through the air to another place. When the excess liquid water is not enough to fill the rivers, they dry up. In order to keep the rivers dry, regular precipitation in the same amounts as in previous years is necessary. And it is the forests, like gigantic natural pumps, evaporating the water that ensure the delivery of even greater volumes of moisture from the ocean to remote corners of the land.
The desert is always locked to moisture. The wind blows there most of the time towards the sea, due to the fact that evaporation above the ocean is more than above the desert. When it rains over the desert, the water quickly flows into the sea or dries out without lingering on the bare soil. Short-term evaporation is not able to attract additional sea air to create new rain. That is why desertification is an irreversible and ever-increasing process.
The forest, unlike the desert, attracts additional moisture. The water vapor that has evaporated from the leaf surfaces condenses in the upper cold layers of the atmosphere, which causes the air above the forest to be diluted, which creates upward air flows over the forest, sucking in moist air masses from the ocean and bringing them to dry land. After precipitation, dry air returns to the ocean through the upper atmosphere.
This process is extended over time due to the fact that the forest soil is saturated with moisture, not allowing water to drain quickly into the sea or evaporate. And long-term strong evaporation forms new rains.
When it works, most of the precipitation is formed over land itself due to evaporation from its surface, and about one-third, or more precisely, 35 out of 100 centimeters of precipitation per year falls on ocean evaporation.
And if oceanic moisture had not been poured onto land by rain and had not fallen snow — all glaciers and swamps, lakes and rivers would have completely dried out in less than ten years.
The Argyll Lake district is in a good location for creating artificial forest planting for several reasons.
1. The presence of a sufficiently large artificial reservoir that can maintain the level of groundwater and ensure daily maintenance of air humidity. This allows us to abandon the artificial watering of seedlings, which creates a more natural engraftment of young trees.
2. A fairly close location to the ocean and the wind rose in this place provides the very 35 percent of the precipitation, recorded at a relatively short distance from the coast. This phenomenon, together with long-term evaporation from forests, is able to intensify and bring moisture further into the interior of the continent.
Thus, the planting forest around Lake Argyll can become the basis for greening an even larger part of the Australian continent.
