Pollination and seed development

The pine nut (seed) species will take a time that depends on the exact species (e.g., 36 months for a stone pine seed) to complete its maturity; to reach full maturity, the environmental conditions must be favorable for the tree and its cone. For some American species, development begins in early spring with pollination. A tiny cone, about the size of a small marble, will form from mid-spring to the end of summer; the premature cone will then become and remain dormant (with a cessation of growth) until the following spring. The cone will then commence growth until it reaches maturity near the end of summer. 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 the drying process. 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 most common and practical extraction method used is the repeated striking of the burlap bag containing the cone(s) against a rough surface to cause the cone(s) to shatter, leaving just the job of separating by hand the seed from the residue within the bag. Another option for harvesting is to wait until the cone opens on the tree (as it naturally will) and harvest the cone from the piñon pine, followed by the extracting process mentioned above. Fallen seed can also be gathered beneath the trees.


Ecology and status

of pine nuts threatens local ecosystems, an effect occurring during the early 21st century with increased culinary uses for pine nuts. In the United States, millions of hectares of productive pinyon pine woods have been destroyed due to conversion of lands, and in China and Russia, destructive harvesting techniques (such as breaking off whole branches to harvest the cones) and removal of trees for timber have led to losses in production capacity.


Elevation and pinecone production

The elevation of the pinyon pine is an important determinant of the quantity of pine cone production, and therefore, will largely determine the number of pine nuts the tree will yield. American pinyon pine cone production is most commonly found at an elevation between , and ideally at . This is due to higher temperatures at elevations lower than during the spring, which dry up humidity and moisture content (particularly snow packs) that provide for the tree throughout the spring and summer, causing little nourishment for pine cone maturity. Although there are several other environmental factors that determine the conditions of the ecosystem (such as clouds and rain), without sufficient water, the trees tend to abort cones. High humidity encourages cone development. There are certain topographical areas found in lower elevations, such as shaded canyons, where the humidity remains constant throughout the spring and summer, allowing pine cones to fully mature and produce seed. At elevations above , the temperature substantially drops, drastically affecting the state of the dormant cone. During the winter, frequent dramatic changes in temperature, along with drying, gusty winds, make the cones susceptible to

Unshelled pine nuts have a long shelf life if kept dry and refrigerated (); shelled nuts (and unshelled nuts in warm conditions) deteriorate rapidly, becoming rancid within a few weeks or even days in warm humid conditions. Pine nuts are commercially available in shelled form, but due to poor storage, can have poor flavor and may be already rancid at the time of purchase. Consequently, pine nuts are often frozen to preserve their flavor. European pine nuts may be distinguished from Asian ones by their greater length in comparison to girth; Asian pine nuts are stubbier, shaped somewhat like long kernels of corn. The American piñon nuts are known for their large size and ease of shelling. In the United States, ''P. edulis'', the hard shell of New Mexico and Colorado, became a sought-after species due to the
