Pinus Spp.

Introduction

Pine trees were planted for erosion control in New Zealand and South Africa (“GISD”)
Most of the exotic forestry is found in the southern hemisphere (“GISD”), but are typically distributed in the northern hemisphere (Fraley)
Pines have a genetic recombination and genetic variation mating system (“GISD”)
There are about 19 species of Pinus that are considered invasive (“GISD”)

Background

There is roughly 111 species of Pine trees to exist (“GISD”)
The largest specie of pine tree. P lambertiana, can grow to about 75 meters in height and be 5 meters in width (“GISD”)
The needles are organized by a bundle there are typically around 2 to 5 and they can grow as long as 45 cm, which is common for the P. palustris (“GISD”)
Pine trees that are usually found in tropical environments keep their needles for roughly 2-3 years and other species that are found in more colder parts keep them for 4-6 years (“GISD”)
Are able to survive for 5000 years (“GISD”)

Figure 4: Relative abundance and richness of plants in the understory of native forests and pine plantations with different origin and number of rotations. (Moomaw et al.)

The general abundance and cumulative number of native forests and pine plantations from different places and the quality of rotations (Moomaw et al.)
A is the plethora of trees in wet environments
B is the number of plants is wet environment
C plethora of exotic trees
D number of exotic trees
E plethora of native herbs
F plethora of exotic herbs
Used two different approaches for conducting they used the Benjamini and Hochberg to test for the Native Forest and the plantations of origin and rotation number (Moomaw et al.)
In the second approach they excluded the native sites and to able to just see the changes in pine plantations. (Moomaw et al.)

Conclusion

The amount of deforestation that goes on in this world is tremendously harming the forests where these types of trees grow, the change from a natural ecosystem to an artificial one. (Moomaw et al.)
The environmental factors that also play a role in the living conditions for some other wildlife can be suitable for certain pinus species. (Moomaw et al.)
The quality and quantity of the plants found in damp conditions were lower in the pine plantations, but there was no huge difference with the plantations from different origins and and quantity of rotations. (Moomaw et al.)
