They appear to be dying. Many people think that trees live to be very old. In some cases this is true.
Some trees live to be over a thousand years old.
However, some trees do not live as long as many people. The poplar and cottonwood trees common in New Mexico rarely live to be as old as people think. These trees grow rapidly so that a 10 to 20 year old tree seems old, just because of its size. In the bosque, some of the native cottonwoods do become old, but when transplanted from the valley, their life span is measured in only a few decades. Many of the poplars and cottonwoods in the heights and on the mesa live to be only 30 years old, or less.
