Experience a palm oasis and all the life that exists there

The history and future of Dos Palmas

"When a man decides he can control nature, he's in deep trouble." — Laura Dern "I think we sometimes give ourselves a little too much credit as humans, as being able to control and understand nature, when in fact we do neither." — Richard Preston California was granted statehood in 1850, and the U.S. military...

What Lake Cahuilla Once Was

"When scientists underestimate complexity, they fall prey to the perils of unintended consequences." — Siddhartha Mukherjee About five million years ago, the uplifting Colorado Plateau changed regional drainage patterns and in doing so created the Colorado River. The Colorado River extends into western and southern Colorado where, depending on the year, the annual snowpack can...

People behaving badly in protected spaces

The improbability that life exists in a desert

Why desert plants are the new kids on the block

“If seeds waited for perfect conditions to grow, there would be no plants in the desert.” — Matshona Dhliwayo In 1977, I was in my fourth and final year of earning my Bachelor of Science degree at the University of California Davis.

Ring any bells? How about Professor Dame Georgina Mace, Commander of the British...

The value of having 'new eyes'

“The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.” — Marcel Proust Discovery, and then independent confirmation, is both the essence and the joy of doing science. That second, confirmation step is what sets science apart from other ways of learning. Children are natural scientists, carefully observing their...

Biodiversity, Part Two

“To many people, ‘biodiversity’ is almost synonymous with the word ‘nature,’ and ‘nature’ brings to mind steamy forests and the big creatures that dwell there. Fair enough. But biodiversity is much more than that, for it encompasses not only the diversity of species, but also the diversity within species.” – Cary Fowler Biodiversity can be...

Beetle Mania

“Biodiversity can’t be maintained by protecting a few species in a zoo, or by preserving greenbelts or national parks. To function properly, nature needs more room than that. It can maintain itself, however, without human expense, without zookeepers, park rangers, foresters or gene banks. All it needs is to be left alone.” — Donella Meadows...

On biophilia and what it means for you

“ Biophilia, if it exists, and I believe it exists, is the innately emotional affiliation of human beings with other living organisms.” — E.O. Wilson Edward (E.O.) Wilson is a naturalist. He is also an eminent scientist. His accomplishments include developing the theory of Island Biogeography with Robert McArthur. The theory is as elegant as...

“The study of nature is a limitless field, the most fascinating adventure in the world” – Margaret Morse Nice Understanding why a creature lives here but not there is among the basic pursuits of a naturalist. Sometimes the answers are obvious: frogs need water; no water, no frogs. Sometimes it takes a bit more thought...

Side-blotched lizards still have stories to tell

“Nature is the source of all true knowledge. She has her own logic, her own laws, she has no effect without cause nor invention without necessity” — Leonardo da Vinci There is joy in hiking a trail. Guilt over tasks not yet completed melts away. Double that joy when joined on the trail with a...

What we can learn from side-blotched lizards

“It appears to me, the doing what little one can to increase the general stock of knowledge is as respectable an object of life as one can in any likelihood pursue” — Charles Darwin Peeling back the complexities of nature to uncover underlying patterns and insights is what scientists, including community scientists, do. In that...

Asking why?

“I have steadily endeavoured to keep my mind free, so as to give up any hypothesis, however much beloved (and I cannot resist forming one on every subject), as soon as the facts are shown to oppose it.” — Charles Darwin My basic question when comparing populations between two of more areas or comparing the...

Quantifying the value of community scientists

Back in 2016 I published a paper that quantified the added value of volunteer community scientists contributing to field surveys of lizards in Joshua Tree National Park. The reason for the paper was that there was and, in some cases, still is a cultural bias ingrained in many professional scientists against the quality of the...
