I am a conservation biologist with over 40 years of experience in ecological research and management, retired after 15 years as a senior scientist with SWCA Environmental Consultants (swca.com). My work has included invertebrate, mammal, bird, amphibian, fish, reptile, and plant surveys of many areas in the Southwestern U.S. and Hawaii.  I have worked in a variety of natural and human-influenced habitats including wilderness, subterranean, aquatic, wetland, desert, riparian, agricultural, and urban habitats. My background combines highly developed field skills, experience exploring challenging environments, natural history interpretation, technical writing skills, and critical analysis abilities.

Most of my work with pollinators has been in the broad field of the study and conservation of rare invertebrates that live in areas that are difficult to study, such as  montane meadows, desert sand dunes, transitory and isolated bodies of water, and caves. Examples of projects I have conducted include: an assessment of potential butterfly habitat along a proposed new trail system in the Spring Mountains National Recreation area; surveys for rare butterflies in the Spring Mountains; a three-year study of the ecology of invertebrates of Organ Pipe Cactus National Monument; development of integrated pest management programs for mosquitoes in wildlife, industrial, and agricultural areas; and field surveys for special-status wildlife and plants in Arizona, California, Hawaii, Nevada, New Mexico, Utah, and Texas.  I have  conducted aquatic macroinvertbrate bioassessments; surveys of food resources for endangered birds; a four-year survey of biota of minor tributaries of the Colorado River in the Grand Canyon, including a range of aquatic resources from small ephemeral rock pools to perennial streams. I have participated in developing conservation plans for threatened and endangered species, including: Multi-species Habitat Conservation Plans for Pima County (Arizona), Clark County  (Nevada), and Washington County (Utah) and the Lower Colorado River (Arizona, Nevada, and California), the Delhi Sands Flower-loving Fly in California, and cave invertebrates in Texas.  I received a Forgotten Pollinators award for my work on the Delhi Sands Flower-loving Fly, which may be the most unpopular endangered species.

I am currently semi-retired, living in Zion National Park in Utah and working as a volunteer for the National Park Service. I am especially interested in and available for projects that involve some measure of adventure and that will lead to greater understanding and conservation of pollinators and other natural resources.
