TREES & THE ENVIRONMENT

THE SCIENCE OF TREES

Without these plants, called trees, were are doomed, but also without "CO2" (carbon dioxide) we are doomed. CO2 is a greenhouse gas ,without which "no"  life on earth is possible. Trees regulate CO2, by taking it in and giving off O2 (oxgen) so animals, aquatic life and humands can exist. If no carbon dioxide is available to plants, there is no life on earth. If you confront scienctists, politicans, environmentalists and the media you might get different answers. One of these groups has even listed CO2 as a hazardous gas?

COUNTING TREE RINGS AS A KID WAS FUN

Today places like Cornell University have data banks of tree rings (dendrochronology) from the Eastern Mediterranean region that date back to 7500BC. They have verified Roman ship discoveries, wooded bowls and crosses as to where the wood was from plus time period.


Bark-outer dead portion of the phleom. A use, cork for your best wine.

Cambium- is a trees growth generator.

Phloem- the outer part of the cambium that moves carbohydrates pruduced in the leaves down throughout the tree for use & storage in the roots.

Xylem-moves water & minerals from roots throughout the tree for defense against disease/decay, insect infestation and growth. Dead xylem cells form the tree rings.

Sapwood- live cells that conduct water.

Heartwood-non living cells that now give trees their structure, whether in trunk, limbs or twigs.

TREES DO FUNNY THINGS

DPD gave me an old Pennsylvania Dept. of Forestry Bullentin #11, printed in 1923. A study on about 100 trees, which included about twenty different species, testing growth patterns. Tree limbs were checked and measured at 7:30 AM every morning & 7:30 PM every evening for amount of growth they put on. The study confirmed that trees grow  67% during the night and only 33% during the day.


Generally a trees feeder root system, that supplies the plant with water and nutrients, are in the top 10 inches of soil. These feeder roots can be out beyond the drip line up to twice the height of the tree. Anchor roots generally within the drip line. Root systems amount to 20% to 30% of a trees volumn.

WATER * SUNLIGHT * GOOD SOIL = TREES

POLITICS OF TREES

If people don't come to the defense of trees, trees won't exist. Politics, to our chagrin, must be engaged to help care for our urban and natural forests. Trees can't move from their site. Therefore they must reach with roots for water, fight off disease, insects attacks and do what a tree can to survive fires. Trees can run from their enemies. Not just about "tree hugging", but common sense. Trees can pose hazards also.

TREES NEED NUTRIENTS

Trees produce  energy to grow, reproduce, develope flowers & fruit production from the power of the sun. Sunlight triggers the photosynthesis process using the water and minerials the roots deliver to trees. Trees are Earth's oldest and largest plant. Humans try  to simulate the same energy production with the development of solar cells, our form of enery production, coping  photosynthesis done in tree leaves. Humans just aren't as good at it as nature.

TREE LIFE A DIRTY HOME

The dirt that trees exist in, well, it's complicated. So we better call it soil. Not only must soils have the correct structure, different size particals, but the right mineral composition. All the essential  minerals are soilds, except one which is a gas, nitrogen. With out the right soil structure ,minerals can be lost by leaching and trees won't anchor themselves very well in the wrong soils.

LIKE A FAMILY MEMBER WITH SPECIAL NEEDS

Trees and all plants need quality sunlight, soil and water. But water is sometimes the cause of decline in trees. Too much, not enough and contamination. Beside the correct amount of water, many times trying to keep plants wet , we find the delivery method the problem. Fungal build-up in hoses and irigation systems end-up harming trees.

Phenology - Pulse of the Planet

We humans keep track of our life events on calendars and by clocks. Plants and animals, most of the time, by seasons which are tuned to tempature/weather. The Science of Phenology is how we tract natures events; When fish spawn, deer mate, insects generate eggs cycles and birds migrate, and various disease cycles in those plants & animals. Computers keep track of these projected events using a temperature recording program called - Growing Degree Days. Just a recent window into this so far (July) - 2018 IS A COOLER YEAR THAN 2017.
