He has conducted threatened and endangered species studies in Montana, Idaho, Washington, Oregon, California, and Hawaii involving a variety of mammals, birds, invertebrates and rare plants. Mr. Hamer has been managing and involved in large research/survey projects for threatened and endangered species since 1977 when he conducted large-scale raptor surveys and raptor ecology studies in southern Idaho and in 1980 when he began the first extensive surveys for the Northern Spotted Owl in the North Cascades. Mr. Hamer is currently a member of the U.S. Fish and Wildlife Service Marbled Murrelet Recovery Team, was a member of the Marbled Murrelet Working Group for the Forest Ecosystem Management Assessment Team and helped assess the viability of all options considered by the President's Plan. Since 1992 Tom has provided environmental consulting services to energy companies, private industries and has worked with state and federal agencies throughout the Pacific Northwest on a variety of environmental issues. He has conducted environmental studies and impact assessments for numerous wind energy projects since 2000, specializing in analyzing potential impacts to resident birds, migrating passerines, waterfowl and bats. Tom obtained his M.S. and B.S. degrees in Biology/Ecology at Western Washington University.
Nathalie Denis, B.S., PMP, Environmental Scientist
Nathalie Denis is a certified Project Management Professional, and has been an environmental scientist for Hamer Environmental since 1999.

Most of these projects involved working with threatened, endangered and rare species of birds, mammals, amphibians and invertebrates. She has managed a large array of studies involving assessing impacts to wildlife from wind energy sites, dam relicensing, fiber optic installations, forestry projects, communication towers, transmission lines and other types of developments. Nathalie has implemented survey methods, conducted extensive data analyses and drafted reports examining population sizes, the risk of collision and potential impacts to several endangered species for several proposed wind energy projects in Hawaii, Washington, Oregon, California and France. Nathalie has managed crews of up to 25 field biologists while ensuring accuracy and quality of surveys, maintaining logistics of survey project and acting as company liaison to contract officers. Since 2007, Nathalie helped create a branch-office in France now called Azimut. She is fully bilingual in French and English. Nathalie received a B.S. in Geography from the University of Montréal.
Erin Colclazier, B.S., Plant Ecologist, Biologist
Erin Colclazier has nine years experience in botanical and wildlife research and project management. For the past five years, she has worked on environmental studies at several wind power projects in Oregon, Washington and Hawaii. She has led a number of large-scale studies involving vegetation cover type mapping, rare plants, noxious weeds, mycological surveys for rare fungi, wetland mapping, and habitat mapping for a variety of wildlife species. In addition to her botanical expertise, Erin has conducted research on birds, small mammals and terrestrial mollusks. Erin has experience designing and implementing large scale restoration projects in the Columbia Basin as well as coastal environments. Her regular duties involved planning, coordinating, and managing multiple projects concurrently, as well as writing, designing and managing projects and budgets. In addition, Erin has many seasons of experience training and leading field crews and working directly with project stakeholders. Erin has significant technical report writing experience including wildlife impact analyses for NEPA documentation, feasibility studies, endangered species evaluations and other planning documents. Erin graduated with a B.S. degree in Environmental Science from Western Washington University.
Joshua Stumpf, M.S., Biologist
Joshua Stumpf has been working as a wildlife ecologist since 1999. Prior to earning his Master of Science in 2009 from Eastern Michigan University, Joshua had the opportunity to work as a wildlife professional for numerous public and private agencies. In that capacity he designed and implemented wildlife and plant studies in a diverse array of habitats, from the southern Cascade Mountains to the Peruvian Amazon. The majority of his work has been with bats, small terrestrial mammals, and carnivores. In addition, he has experience with herptofauna, plants, owls, fish, and aquatic habitats. Most recently, Joshua completed a two-year study on niche partitioning of roosting and foraging habitat of the endangered Indiana bat and its sympatric congeners.
Glenn Johnson, M.S., Avian Biologist
Glenn Johnson has conducted and supervised field research on land-birds and other wildlife since 1995 throughout western North America, including extensive work in Washington, Oregon, northern California, Arizona, Nevada and northwestern Mexico, and recently in Hawaii, Florida, and Minnesota. In addition to private sector experience, Glenn has worked for government agencies including the U.S. Forest Service, U.S. Geological Survey, and the Arizona Department of Game and Fish, as well as conducting research for conservation science organizations such as the Klamath Bird Observatory and Sustainable Ecosystems Institute. He completed an M.S. in Wildlife Science at the University of Arizona in 2011, modeling riparian bird abundance and diversity in relation to ecosystem restoration, beaver reintroduction, and surface water availability in a desert riparian area. Glenn manages projects involving community-level metrics as well as targeted surveys for endangered, threatened, and at-risk birds and other wildlife. Glenn has extensive trapping and marking experience, is certified by the North American Banding Council at the bander and trainer levels, and he has trapping and telemetry experience with small- and medium-sized mammals. While most of GlennŐs field survey and banding work have focused on multi-species sampling, he has also worked specifically with ESA-listed species including Northern Spotted Owl, Marbled Murrelet, Southwestern Willow Flycatcher and Bald Eagle (desert-nesting population).
Delphin Ruché, M.S., Biologist
Delphin Ruché is a wildlife biologist. He has worked for Hamer Environmental on various projects in the states of Washington and Hawaii, using radar technology to assess the impact of aerial structures on wildlife, and assessing habitat quality of threatened species. Delphin Ruché has a M.S. degree from the University of Québec in Montréal, Canada. Delphin's international experience includes wildlife conservation projects in Europe, Africa, Antarctica and Canada. In the USA, he was involved in various projects in research and conservation with the USGS, California State Parks and the University of California Los Angeles, where he taught as a lecturer. Delphin Ruché recently opened a new company in France, Azimut, with the help of Hamer Environmental. Azimut offers radar expertise and other services to wind energy developers and consulting firms.
Dan Varland, Ph.D., Biologist
Dan Varland has sixteen years of experience in wildlife research and management in the Pacific Northwest. He has a Ph.D. in Animal Ecology from Iowa State University and B.S. and M.S. degrees in Zoology from Eastern Illinois University. As a Wildlife Biologist working with the forestry industry for most of his years in the Northwest, Dan worked with state agencies, foresters and land managers to develop habitat management plans for the Marbled Murrelet, Northern Spotted Owl, Bald Eagle and other old growth obligates. Dan has extensive knowledge and expertise in the Sustainable Forestry Initiative (SFI) program and program certification, having served as SFI coordinator for Rayonier lands in Washington from 2005 to 2008. Dan was Co-Principal Investigator for a six year study of Northern Goshawk ecology in managed forests, a project resulting in two peer-reviewed publications that included forest management recommendations for goshawks. Dan was Co-Principal Investigator for an on-going cavity creation study that began in 1996 and is focused on creating wood decay through the inoculation of trees with fungi, the goal which is to provide habitat for cavity-dependent birds and mammals. Dan's doctoral research was on American Kestrels nesting in nest boxes attached to highway signs along an interstate highway in Iowa. Since 1995, Dan has been color marking raptors and conducting line-transect surveys by vehicle along Washington's outer coastal beaches.
