Bryce Maxell, Program Coordinator
Joined MTNHP in January 2005

Bryce Maxell grew up surrounded by a variety of farm animals and spent many hours dogsledding in the mountains of Utah.  He completed a B.S. in Biology and a B.A. in Economics at the University of Puget Sound in 1994 where he studied the demography of kelp species in the Puget Sound and was an NAIA All-American swimmer.  After his undergraduate degree, he received a Thomas J. Watson Fellowship for a yearlong independent study of the natural history of Australia and New Zealand in 1994 and 1995.  Bryce completed his Ph.D. in Fish and Wildlife Biology in the Wildlife Biology Program at the University of Montana in 2009 where he completed a state-wide status assessment of, and constructed predicted habitat suitability models for, Montana's amphibian and reptile species and examined the population demographics of Columbia Spotted Frogs.  Between 1996 and 2015, Bryce conducted field inventories for a variety of animal species in Montana.  During his time in Montana he has authored or coauthored three books, a dozen peer reviewed publications, and 35-plus professional reports on amphibians, reptiles, bats, small terrestrial mammals, birds, terrestrial mollusks, and fish.  Bryce is passionate about making biological information available to resource managers and the general public so that Montana's plants, animals, and terrestrial and aquatic communities can be appreciated by current and future generations and is excited to lead Heritage Program staff in this endeavor.

Information Systems and Services

Dave Ratz, Web Projects Manager
Joined MTNHP in July 2007
Dave Ratz ("Ratz") was an Air Force Brat, born in Okinawa, raised everywhere, finally settling down in the Rocky Mountains.  He's worked in computers for 33+ years but has tried his hand at everything.  At age 25, Ratz suffered a quarter-life crisis: sold everything, bought a backpack and lived in the woods for eight months.  If it weren't for Loma Linda University dragging him back into the workforce, he might still be there.  Alas, for every time there is a season, and now he can't get by without his six monitors, cell phone, and golf clubs.

Ratz is the proud papa of various web "children": You can find his office by looking for the most decorated 'cube' nestled among the other talented data geeks.

Scott Blum, Biologist/Information Specialist
Joined MTNHP in November 2004
Scott Blum's current focus is reviewing Heritage database records for animal observations: if you've submitted an animal observation to NHP, there's a better than good chance that Scott has given it the once over.  Scott was born and aged in Oswego, New York on the shore of Lake Ontario (Official Town Motto: "Oswego, where the water never ends." Unofficial Town Motto: "At least we're not Fulton.").  In fits and starts, he completed a B.S. in Zoology (SUNY Oswego) and an A.S. in Zoo Animal Technology (SFCC Gainesville, Florida); subsequently launching and crashing a brief career as a zookeeper at the Racine Zoo in Wisconsin and the Brookfield Zoo in Illinois.  After a nine year sabbatical at Pet Pals pet store (Liverpool, NY), he returned to school to chase mountain lions for his M.S. in Ecology from Idaho State University, Pocatello.  During and after graduate school he spent time as a technician on various research projects including tracking lynx and coyote around Seeley Lake and collecting bear hair in the Swan Valley.  Scott spends his time in and around Helena hiking with his dog, Bug, and honing his bread baking skills.

Braden Burkholder, Data Systems and Sciences Lead
Joined MTNHP in June 2013

Braden Burkholder specializes in bridging the divide between on-the-ground biological knowledge and technical data solutions, while claiming expertise in neither.  He has over 16 years' experience in wildlife ecology and data management, anchored by a B.A. in Biology from Whitman College and an M.S. in Fish and Wildlife Management from Montana State University.  Braden has found his niche as NHP's Data Systems and Sciences Lead, which can be boiled down to: solving problems to improve the data resources available for native species conservation, invasive species management, and habitat stewardship in Montana.  Despite more familiarity with vertebrate taxa, he has been able to contribute to a diversity of projects involving Zoology, Botany, and Ecology Program staff at NHP.  His current responsibilities include: administering NHP's internal databases, integrating large observation and survey datasets into NHP databases, producing habitat suitability models for Montana's Species of Concern, managing and analyzing mountains of bat acoustic data, writing scripts for task automation, and creating tools to simplify data submission.  He has been accused of wizardry in the realms of GIS, Python and geospatial data manipulation, but insists these rumors are unfounded.  A Helena native, Braden frequents the renowned trails of the South Hills on foot and bike when not at his desk.

Andrea Pipp, Botany Program Manager
Joined MTNHP in October 2014

Andrea Pipp serves as the Program Botanist for the MTNHP.  She earned a BA in Zoology (1989) and a MS in Wildlife Biology (1998) from the University of Montana.  Every wildlife job required studying habitat and Andrea became more and more interested in vascular plants, then intrigued by mosses, dabbled with fungi, and really took a liken to the lichen communities.  Her master's study evaluated if canopy lichen biomass, species diversity, and community composition was more influenced by the age of a forest or by the structure of that forest.  She has been certified as a Lichenologist for Macrolichens of the Pacific Northwest since 2001.

Andrea has 29 years of botany and wildlife experience working in 12 states for the federal, state, and private sectors.  Her past project work was focused on issues relative to forestry, stream and wetland restoration, transportation, residential development, and oil/gas development.  Her specialties are in vascular plant (native/exotic), lichen, and bryophyte identification, surveying, and monitoring, wetland delineation, resource impact assessment, and technical writing.  She serves on the Board of the Northwest Scientific Association and is a member of the Montana Native Plant Society, Friends of the UM Herbarium, Northwest Lichenologists, and American Bryological / Lichenological Society.

Kenda Herman, Botany Data Assistant
Joined MTNHP in August 2020
Kenda Herman is a biologist with a background in environmental science and plant ecology.  She earned a B.S. in Environmental Science from the University of Montana-Western in 2012.  Kenda has spent most of the last 15 years working in support of land management, research, and conservation, including operating a small business designing functional landscapes for restoration, habitat enhancement, and water conservation projects using ecological concepts.  Many years of inventory and monitoring of natural resources, from alpine plants to amphibians, fueled Kenda's interest in ecology research.  Eventually, she found herself in Florida conducting research in a globally imperiled habitat on plant population viability and plant response to conservation management strategies.  Kenda is thrilled to be part of the team at the Montana Natural Heritage Program to help supply good science to anyone with an interest.  In her off time, she can be found enjoying public lands and waters, checking the Restore for treasure, or fussing with her community garden.


Dan Bachen, Senior Zoologist
Joined MTNHP in May 2016

Originally from rural Alaska, Dan Bachen grew up surrounded by mountains with abundant outdoor recreation opportunities and a diverse community of fish and wildlife species.  Dan eventually moved south to Montana and received his B.S. in Wildlife Biology from the University of Montana, and his M.S. in Fish and Wildlife Management from Montana State University.  Over his career he's had the opportunity to work on a wide variety of taxa from charismatic megafauna like elk and grizzly bears to charismatic microfauna such as bats and terrestrial small mammals, birds, reptiles, amphibians, and other nongame species.  His previous work included establishing baseline surveys for nongame species across the northern Rocky Mountains and Great Plains, exploring how invasive brome grasses impact small mammals in sagebrush-steppe habitats, modeling disease ecology of large mammals in the Greater Yellowstone Ecosystem, and other projects.  Outside of work Dan enjoys rock climbing, skiing, backpacking, hunting, and hiking.
