For this Casuarina experiment a ridge crest (at about 600 mts high) with good sunlight exposure was chosen.
We have 5 trees, planted 2 years ago at the same time. The tallest is about 2 mtrs.
They were seeded at the same time, but have different growth pattern and shapes.
This site receives the strongest autumn winds we get around.
They are also exposed to the north freezing winds, and tip damage accurs in such events.
They will function has a south side windbreak edge along with Rosemary planted under their canopy.
In the future they will be pruned so as to cut limit their growth vertically and expand their growth horizontly.
They are the south edge of a agro-forestry flood irrigated tiny system that includes other trees like olives, pomegranate, peach, plums, apples, cherry, and kaki, plus perenials like palm cabbage, jerusalem artichoke, raspberry and mint.
Annual crops this spring include potatoe, lettuce, beet, palm cabbage, onions.
This tree performs the functions:
- capture wind energy and transform it into (very useful) wood, protecting other trees from wind damage
- capture sunlight relieving sunlight stress from other (deciduos) trees
- nitrogen fixing into the soil
- production of mulch, litter/leaves to use in the vegetable garden nearby
- produce seeds with new "local" genetics
