  • Largest and heaviest of our native North American deer, moose are rapidly declining in numbers due to a number of factors other than habitat loss. Increasing numbers of white-tail and black-tail deer due to predator decline are introducing new parasitic diseases such as brainworm and liver fluke into already stressed populations of adult breeding moose. This cow was seen foraging in a pond near the Idaho-Wyoming border near Jackson Hole.

  • This natural hybrid (Opuntia engelmannii x phaecantha) of two common and local prickly pear cacti - the Engelmann's Prickly Pear (Opuntia engelmannii) and the brown-spined prickly pear (Opuntia phaecantha),  shows characteristics of both and have resulted in a large, mature beautiful cactus growing at some elevation in the Ajo Mountains in Southern Arizona. Since so many of our native members of the Opuntia genus are so closely related and have overlapping natural ranges, hybridization is common among many species, and is the source of much confusion and frustration for biologist and naturalist alike! This particular plant has the beautiful silvery white spines and flower petal shape of O. engelmannii and the flower coloration and growth pattern of O. phaecantha.

  • Engelmann's prickly pear is one of the most (if not the most) widespread of the prickly pear cacti. It is found in all of the American Southwestern States (except Colorado) and can even be found as far east as Louisiana, Mississippi and Missouri and is widespread throughout much of Mexico. Oddly enough , it has become an invasive species in Kenya! The sweet, juicy fruits are a traditional and still very important food source wildlife an for many tribes and nations of the Native Americans and is commonly used in Latin American cuisine.

    Engelmann's Prickly Pear
  • Common in lower elevations of western/southwestern Texas and much of Mexico's Chihuahuan Desert, this is the only native prickly pear in the region without long spines. Instead, brown hair-like glochids grow in the areoles, which if touched, can be quite painful and difficult to remove. This one was  photographed just north and below the Chisos Mountains in Big Bend National Park in Brewster County, Texas.

    Blind Prickly Pear
  • This non-native European import is now found across most of North America, excluding parts of the South. Used since antiquity for medicinal use, it is toxic to humans and animals. These were found growing on the lower slopes of the North Cascades in Northern Washington.

    West Indian Manatee
  • A small herd of female elk (cows) gracefully sleep or graze in the late autumn afternoon sun in Central Oregon, while less than a mile away - a herd of bulls compete for dominance of this harem, of which there will be only one winner.
    The Harem
  • A very common aquatic wildflower found all across Western North America,  the yellow pond-lily is a type of spatterdock often confused with water lilies. This one was photographed in the sub-alpine elevations of Oregon's Mount Hood. An interesting side note is that the seeds are edible, and will pop just like popcorn!
