They have male cones which produce pollen thatis wind dispersed, and woody cones where seeds are born.

Two Ways to Observe Conifers
The phases you monitor for Conifers will depend upon whether you are observing your plant using Single Reports or Regular Reports.
Regular Reports: Using Regular Report forms, you track your plant (or plants) throughout a season, recording the dates when key leafing, flowering and fruiting events occur (event-based reporting). The Regular Report phenophases for Conifers are: First Needles, First Pollen, Full Pollen, First Ripe Fruit, Full Fruiting.
Single Reports: Using Single Report forms, you select a phase that best describes the leafing, flowering, or fruiting phase that your plant is currently in (ie. Flowers-middle or Flowers-early) on the day you happen to see it (status-based reporting). The Single Report phenophases for Conifers are: First Needles (None), First Needles, Pollen (None), Pollen (Early), Pollen (Middle), Fruit (None), Fruit (Early), Fruit (Middle), Fruit (Late).
