Thanks to Hubble Ray Smith for the inspiring article about the Hualapai Ka-Voka Jackson and other UNLV ecology students restoring native plants.

It reminded me of a story from the past, a slice of Arizona Indians' history before the white people came. It was a battle between the Hualapai and the Yavapai. Afterward, a monument of two rock piles went up and maybe still exists there somewhere. This piece of history is in the book, "Oral History of the Yavapai," page 214. Every Arizona Indian tribe should have an easy-to-read complete history book like this one. Thank you.

A pink flower bloomed from the cactuses. The small sign of life appeared just one month after UNLV student Ka-Voka Jackson began a project to research the best way to eradicate invasive plants and bring new, but familiar life to her ancestral land in the Glen Canyon National Recreation Area. The cactuses may be one way.

In a remote canyon off the northern reaches of Lake Powell, a fourwing saltbush is growing deep roots as part of Ka-Voka Jackson's experimental plots of native plants. The silvery, sea-green shrub is joining grasses and succulents in Jackson's efforts to remedy ravenna grass infestations that threaten native flora and fauna in the sacred ancestral lands of her tribe and others around the Colorado River.

Itchy, watery eyes, congestion and don't forget the sneezing. Have you seen the yellow dust collecting on your car? The culprit is pollen and it has been floating in the air much earlier than expected this year. Plants pollinated by insects are not the biggest offenders, the highest pollen producers are male trees that spread pollen by the wind. University of Nevada Cooperative Extension Professor M.L. Robinson said this pollen came early this year due to the mild winter and early spring.

If the sneezing, wheezing and nose-running weren’t enough evidence, the monitor on the roof of the Juanita Greer White Life Sciences building at UNLV confirms the worst.

In recent years, conservation and environmental awareness have become sexy topics on college campuses, but two University of Nevada, Las Vegas (UNLV) students have gone beyond words, bumper stickers and fancy slogans.

In dry, disturbed soil throughout the West, a weedy invader from Eurasia has gained a tenacious foothold. Kochia scoparia, also called poor man’s alfalfa, has slender, gray-green leaves that turn an ornamental orange in autumn. Despite control efforts, this weed springs back relentlessly thanks to its bountiful seed bank.

Armed with shovels, the group turned enough dirt to plant 630 trees and grasses along the Las Vegas Wash, an area that was once submerged and served as a docking area for boats. “This area was 50 feet below Lake Mead,” said Dr. Scott Abella, assistant professor in the School of Life Sciences at UNLV.

More than 90 species of U.S. specialty crops require pollination, and various animals, including bees, butterflies, moths, bats, and birds are a critical part of the pollinator-plant ecosystem. Despite the myriad species of pollinators available, American farmers rely on one species of honey bee, Apis mellifera, for most of the pollinator services to pollinate their crops. Wild and managed bees together add $15 billion in crop value each year.

Parasitic bacteria that are entirely dependent on the other bacteria they infect have been discovered for the first time, in human spit. The tiny cells have gone undetected for decades, but appear to be linked to gum disease, cystic fibrosis and antimicrobial resistance.

Imagine a white sand beach with a bar at the dock. Water skiers flash by a small island, where fireworks shoot from twin peaks. Now imagine this water paradise is in the desert of drought-stricken Nevada.
