How do you identify a pine tree? Well, 9 out of 10 would tell the needle-like shape of leaves and the cones. Well, there are some interesting facts about the needles and cones too, apparently. No other kind of plants on earth is ‘blessed’ with such features.

Needle form is actually the final and adult form of the leaves, having it evolve from seed leaves, juvenile leaves, and scale leaves before. All of the previous forms are not photosynthetic, while the needle form is. The needles can stay on the trees for 1.5 to 40 years, depending on the species.

The cones are more interesting part of the tree. Pine trees have no flower or fruit, instead they have woody wedges in the shape of “cone” for their gymo (naked) seed that contains pollen. Thus, basically the cone is a part of their reproductive organ.

There are male and female cones in one pine tree. The male ones are smaller and only present for a short period of time during spring or autumn. The male cones fall immediately right after they have shed their pollen.

The female counterpart last far longer, since for the seed to mature after pollination requires up to 3 years, with another year of delayed pollination. After pollination, the female cones will produce seed that will later will be dispersed by wind. Pine is the only known plant to reproduce like this.

Depends On Forest Fire


Forest fire is not a good thing for other plants except pine trees. In fact, many species of pine trees depend on small forest fire, especially ground fire, to survive and grow well. This is the reason why Australian forests grow well after fire.

The evidences can also be seen from how jack-pine, ponderosa, and longleaf pine trees are able to thrive well in America. With the ability to survive fire, pine trees tend to prosper and stand out in areas with regular fire or areas with such history.

Some pine trees develop thick bark, and this is the reason how they are able to survive mild forest fire. During the mild fire, other competing trees especially hardwoods will not be able to survive and just die or burn. Pine trees with thicker bark will only shed their outer bark and continue to live.

With less competitors around, the pine tree would be able to grow bigger. It can even absorb more nutrients from the soil since burnt forest is full of organic matters. Such nature can be seen from how dried pine leaves are easily burned, in which will help to start and spread fire.

We should also mention some species of pine trees such as jack pines and lodgepole pines which depend on heat from wildfire to open the cones and spread seeds. In short, a burnt forest is necessary for the best growth of the plant.
