In 2008 the company became incorporated as BIO-Logic, Inc. Since founding BIO-Logic Mr. Boyle has led biological field surveys and written impact analysis reports for more than 50 projects involving electric transmission line siting and reauthorization, oil and gas development, buried utility siting, land transfers, and terrestrial and aquatic habitat restoration projects. For these projects he has performed agency consultations, designed and led biological field studies, and prepared Biological Assessments, Biological Evaluations, and NEPA document sections. Mr. Boyle has prepared regional conservation assessments for the U.S. Forest Service including Management Indicator Species assessments for the San Juan National Forest and species assessments for Region 2, and prepared a Sagebrush Conservation Assessment & Strategy and Gunnison Sage-grouse conservation agreement documentation for the Colorado Division of Wildlife.
As former Senior Wildlife Biologist for AGEISS Environmental, Inc., Mr. Boyle was Principal Investigator for research projects on pronghorn, feral horses, bats, and bird communities at U.S. Army Dugway Proving Ground, Utah . Mr. Boyle authored a Training Area Management Plan at DPG and provided expert consultation on vegetation community changes and associated effects on wildlife. Mr. Boyle also has extensive research experience investigating spotted owls, kit fox, mule deer, elk, bighorn sheep, wild turkey, and desert tortoises. He was an invited reviewer of the Colorado and Southwest Regional Gap Analysis Projects, critically reviewing theoretical models linking vertebrate species distributions to habitat characteristics. He performed extensive fieldwork for and co-authored the Colorado Breeding Bird Atlas. Mr. Boyle was certified in Denver Federal Circuit Court in 1999 as an expert witness for wildlife biology, wildlife habitat, and hunting safety. Prior to consulting work, Mr. Boyle was District Wildlife Manager for the Colorado Division of Wildlife, Research Technician for the U.S. Fish and Wildlife Service in Fort Collins , Colo. , and Research Associate of the Department of Fishery and Wildlife Biology, Colorado State University.

Alison also conducted wetland delineations and wrote permit applications for compliance with the federal Clean Water Act and the state Fish and Game Code. She is certified in wetland delineation from the Wetland Training Institute. While at the DOT, Alison also developed mitigation projects involving land acquisition and the purchase of conservation easements and wrote mitigation and monitoring plans. Alison also worked as a private consultant for nine years, overseeing a diversity of projects for government agencies, non-governmental organizations, and private clients, with a focus on listed plant conservation and recovery. Projects included experimental field research on a variety of federally listed plant species, the development of a long-term monitoring program for a federally endangered orchid, and analysis and review of long-term community monitoring data from Santa Cruz Island. She taught plant systematics at the University of California in Santa Cruz and worked as a scientific writer and editor.
