Other: The genus name, “Tamarix”, is named for the Tamaris River in Spain and the species name, “chinensis”, means “of China” which refers to its Eurasian distribution.

It was well established by the 1920's along the Colorado River and its tributaries. It spreads so rapidly and so extensively that there is little hope of eradicating it.

Pinyon Pine

Pinyon trees do not produce pine nuts every year. These delicious nuts can only be harvested every three to seven years. This irregular schedule prevents animals from adapting to an abundance of pine nuts and guarantees that at least some nuts will become new trees instead of a quick meal.
