Pine cones are male or female, the reproductive system is called strobilus. The male strobilus grows pollen and releases it into the wind where it lands on the female strobili of neighboring trees to create new pine seeds. Due to the extreme climate changes, the pines have to adapt to survive with less water, higher temps and the soil with different composition.
The structures can be renewed in every couple of years. As the community of Eberswalde, pinecones are also formed by circular layers that protect its seeds.
Classification
Every pinecone is selected and classified in terms of kind, size, condition.
