Closed cones indicate damp conditions while open cones indicate the forest floor is dry. As a result of this, pine cones have often been used by people in temperate climates to predict dry and wet weather, usually hanging a harvested pine cone from some string outside to measure the humidity of the air.
Overstory species include coulter pine, monterey pine, bishop pine, shore pine, and several endemic cypresses, species which generally rely on fire to open their cones and release seeds. Closed-cone forests often grow in low nutrient and/or stressed soils, which can lead to slow growth. [1]
The cones thus grow over a two-year (26-month) cycle, so that newer green and older, seed-bearing or open brown cones are on the tree at the same time. Open cone with empty pine nuts. The seed cones open to 6–9 cm (2 + 1 ⁄ 4 – 3 + 1 ⁄ 2 in) broad when mature, holding the seeds on the scales after opening.
The mature piñon pine cone is ready to harvest ten days before the green cone begins to open. A cone is harvested by placing it in a burlap bag and exposing it to a heat source such as the sun to begin drying. It takes about 20 days until the cone fully opens. Once it is fully open and dry, the seed can be easily extracted in various ways.
The leaves snap cleanly when bent; this character, stated as diagnostic for red pine in some texts, is however shared by several other pine species. The cones are symmetrical ovoid, 4–6 cm (1 + 1 ⁄ 2 – 2 + 1 ⁄ 4 in) long by 2.5 cm (1 in) broad, and purple before maturity, ripening to nut-blue and opening to 4–5 cm (1 + 1 ⁄ 2 –2 in ...
Coulter pine (Pinus coulteri), or big-cone pine, is a conifer in the genus Pinus of the family Pinaceae.Coulter pine is an evergreen conifer that lives up to 100 years. [2] It is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico, occurring in mediterranean climates, where winter rains are infrequent and summers are dry with ...
Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.
The cones are globose, 4–5.5 cm (1 + 5 ⁄ 8 – 2 + 1 ⁄ 8 in) long and broad when closed, green at first, ripening yellow to orange-buff when 18–20 months old, with only a small number of thick scales, with typically 5–10 fertile scales. The cones open to 5 to 7 cm (2 to 2 + 3 ⁄ 4 in) broad when mature, holding the seeds on the ...
