Developing pollinator-dependent plant materials for use in a growing restoration economy

Projects Posted on: March 08, 2019
Located on the Sierra Ancha Experimental Forest, this project uses a common garden approach to determine which plant species are best suited for supporting pollinator communities and are most appropriate for restoration activities. Findings from the study will be used to 1) improve pollinator habitat, 2) increase seed stocks of native flowering species for use in restoration, 3) inform U.S. seed zone guidelines and 4) help predict plant-pollinator response to climate change. This carries on a long tradition at the Sierra Ancha Experimental Forest of using common gardens in botanical research. As far back as the 1920s and 30s common gardens were used to study evapotranspiration rates of native herbaceous and shrub species as well as evaluate the potential use of certain species for erosion control. Some of these the same gardens are now being restored nearly a century later for use in this study.

Drought and increased CO2 alter floral visual and olfactory traits with context-dependent effects on pollinator visitation

Publications Posted on: April 26, 2018
Climate change can alter species interactions essential for maintaining biodiversity and ecosystem function, such as pollination. Understanding the interactive effects of multiple abiotic conditions on floral traits and pollinator visitation are important to anticipate the implications of climate change on pollinator services.

Assessing “pollinator-friendliness” of native plants available for restoration

Projects Posted on: April 20, 2018
This project will conduct a science-based assessment of the pollinator-friendliness of plant species available for restoration and rehabilitation projects in Region 1.  A guide will be developed for several habitat types to tailor and recommend seed mixes that support the greatest number of species and abundance of pollinators.

Plant Guide: Yellow beeplant (Cleome lutea Hook)

Publications Posted on: October 03, 2012
Yellow beeplant is a valuable native forage species for bees wasps and butterflies. Over 140 species of native bees have been observed foraging for nectar or pollen on yellow beeplant in southern Utah (Cane, 2008). Yellow beeplant is an annual forb which could provide food to insects in the first growing season of a range seeding (Ogle and others, 2011a).

Plant Guide: Blue penstemon (Penstemon cyaneus Pennell)

Publications Posted on: October 03, 2012
Blue penstemon is suited for use in restoration and wildlife enhancement plantings. It is not noted for having value as forage for livestock, and forage use is limited by big game. The fibrous root system and wide canopy cover make it a good plant for low-water use landscaping (i.e. roadsides) and other ornamental plantings.

Predicted fates of ground-nesting bees in soil heated by wildfire: Thermal tolerances of life stages and a survey of nesting depths

Publications Posted on: October 04, 2011
Periodic wildfire defines plant community composition and dynamics in many of the world's semi-arid biomes, whose climates and floras also favor wild bee diversity. Invasive flammable grasses, deforestation, historical fire suppression and human ignition are increasing fire frequency and intensifying its severity, as well as introducing fire to previously fireproof biomes. In many of these habitats, bees are key pollinators.
