It depends what you want to use them for. If you are growing them for timber, you need to plant with approximately 4 X 4m spacing, so no more than 750-800 trees per 10,000m2.
If you are growing the trees to be harvested at a young age, for biomass, sticks or similar, you can plant more intensively and closer together.
The key is that larger trees need more space to grow.
The larger the tree needs to grow, the less trees you can plant.
Depending on the timber use, Paulownia can be cut back after anything from one year (for biomass growth) to 20 years (for large timber board). Common practice is to harvest the Paulownia timber from the age of 5-8 for high quality wood. At this age, Paulownia trees can grow to the size equivalent of a 25 year old Teak tree. For optimum timber production efficiency, under good conditions, harvest would be done at year 10.
Any Carbon offset credit project involves a great deal of time, work and expertise. Revenue from Carbon offset credit sales can go towards a Paulownia plantation, but since certification can take 5 years to achieve, some upfront capital is required to start the planting. You will need to conduct a great deal of research before starting the project and have a Carbon expert working with you. One existing Paulownia plantation that is applying for Carbon offset credits is the Princess Project Panama
According to the World Resources Institute, there are 100,000 known species of trees.
Deforestation could not be replaced. We have to plant trees to minimize depletion.
Sort of, You could plant (lets say 100 trees) and cut down 100 trees or cut them down then plant them again
Ozone depletion could be avoided easily. You have to plant more and more trees.
Plant them in a star, with four trees in each line.
Trees are plants!! trees are plants
Most trees which are trees are trees, also when they're not. Sometimes a tree which is actually a tree but a tree afraid to admit he is a tree is called a busheee.
we can but with oxygen tanks. but its because it does not have any water or good soil to plant fruits or vegetables or trees so we could breathe mars however we could live on because it has good soil and known to have water so first astronauts have to plant trees and food so trees produce oxygen so we could breath and food to eat.
you could plant more and don't rip them out of the ground. You can plant more seeds and save trees. Don't abuse the plant cycle and burn plants.
You could plant some flowers or trees, or you could pick up garbage. Anything that helps the envirnment.
