The Pine Tree is a very common species in the
in the upper midwestern part of the United States. Pine trees are conifers (evergreen trees) and reproduce using cones.
The pine trees have both male and female cones.
The male cones are smaller than the female cones. The seeds mature in about two
years. The mature seeds have winged parts that twirl and float in the wind. This
allows the seeds to travel away to new locations where they try to grow. Although

seeds fall on areas where they cannot grow and others become food sources for a
wide variety of birds and mammals.
