Phenophases
First Needles
Date when new needles emerge from tips of buds, or are visible from the side of the buds on three or more branches.
First Pollen
Date when the plant starts releasing the powdery, yellow pollen from three or more branches (from male cones which are usually small and rounded). When open, the male cones will release yellow pollen dust when touched.
Full Pollen
Date when half or more branches have pollen.
First Ripe Fruit
Date when you notice the first seed cones becoming fully ripe or seeds dropping naturally from the plant on three or more branches. Record when the seed cones turn brown and the scales expand (seeds should start dispersing shortly thereafter).
Full Fruiting
Date when half or more branches have fully ripe cones or most of the seeds are dropping naturally from the tree.
