Do pine trees produce cones every year?
Pine trees may actually vary their pine cone production year to year as a way of throwing off predators and to increase the rate of successful reproduction. Different environmental conditions can also influence when cones are produced. These factors include water levels, nutrient availability, temperature, and sunlight conditions.

Examples of their use includes seasonal wreaths and decorations, fire starters, bird feeders, toys, etc. An intriguing derivation of the impossible bottle mechanical puzzle takes advantage of the fact that pine cones open and close based on their level of dryness. In constructing the pine cone in the bottle display, a closed, damp cone of suitable size is inserted into a narrow-mouthed bottle and allowed to open upon drying.
Why do pine cones open when dry?
A pine cone will go through many cycles of opening and closing during its life span, even after seed dispersal is complete. This process occurs with older cones while attached to branches and even after the older cones have fallen to the forest floor. The condition of fallen pine cones is a crude indication of the forest floor's moisture content, which is an important indication of wildfire risk. Closed cones indicate damp conditions while open cones indicate the forest floor is dry.
