Leave it to NC readers to recognize yesterday’s Mystery Photo! I was impressed with the fat tire track guesses – something I would never ever recognize! With the help of the wind and a gentle slope, a White Pine cone rolled down a hill, leaving the imprint of its spirally-arranged scales in a repetitive pattern. The fall cone crop of many conifers this year was extreme, so your chances of coming across this track are great this winter.
All species of pines produce cones with scales that overlap each other like fish scales. During cold, damp weather, these scales close tight to protect the seeds within them from bad weather and hungry animals. When the weather is conducive to germination (warm and dry) the scales open, allowing seeds to escape. Even after cones fall from the tree, their scales can still open and close.

What is this white foam at the base of this White Pine, and how did it get there? Please submit answers under “Comments” on my blog site, http://www.naturallycuriouswithmaryholland.wordpress.com.
If you’ve noticed yellow clouds near pine trees recently, or a layer of yellow “dust” on your car or pond, you’ve witnessed the annual dispersal of pollen by male pine cones. Light and fluffy so as to be easily distributed by the wind (rather than insects), these minute pollen grains containing sperm cells can be found just about anywhere this time of year, including the nostrils of humans. All pines have separate male and female (seed) cones on the same tree. Male pine cones, which produce pollen, are much smaller, occur in clusters, are more papery, and remain on the tree for a much shorter period of time than most female pine cones. (By July they will litter the ground beneath pines before they quickly disintegrate.) Although it may mean a brief period of sneezing has to be endured by those allergic to it, this “golden smoke” not only creates beautifully intricate patterns for us to enjoy and makes it possible for pine trees to make the next generation of seeds, but it is also touted as an agent of increased testosterone and strong sexual libido, anti-aging, skin rejuvenation and improved immune systems for humans. Haste ye to a natural food store (or the closest pond!). (photo – Red Pine pollen & male cones)
