Green sweat bee visits a blackberry flower
Fruits of Her Labor: the flower on the left has been pollinated and the fruit is developing, but the flower on the right is still being pollinated, highlighting the importance of bees to humanity's food resources.

Halictus ligatus female on an oxeye daisy (Chrysanthemum leucanthemum)
The center of the composite flower looks like a "landing zone" and has evolved to guide pollinators to its nectar/pollen.

Looking down on camp at Big Pine, Red Canyon.
The photo shows the SCREE Powell 150 expdition camp at Big Pine Campground in Red Canyon of the Green River, Utah. The large green tarp was set up to keep the kitchen area and campers dry. Two very large ponderosa pines are in the center of camp, and surely were witness to the 1869 Powell expedition.

A small tributary adding water and sediment to the Green River, Red Ca
This photo displays the contrast between the clear, sediment-starved waters released from a large dam, and the murky, sediment-rich waters of natural tributaries. The tributary is just one of many that gradually re-supply the river with sediment.

Bat call and insect data collection in Red Canyon.
This photo demonstrates the typical set up of the so-called 'bat-and-bug' citizen science data collection platform used on the SCREE - Powell 150 expedition. The UV light attracts bugs to the pool of ethanol, where they land and are preserved for identification, while the touchpad device has an untrasonic microphone to collect bat calls.

Clump of scarlet desert paintbrush at Flaming gorge dam
Desert paintbrush stands out against the yellows and browns of the desert by way of its bright red and fiery coloring. Desert paintbrush is a hemiparasite, and takes some of its water and nutrients from the roots of nearby plants. However, unlike full parasites, desert paintbrush can still photosynthesize to obtain some of its nutrients if needed.
