Tansley Team, Inc.

Tansley Team, Inc. was named in honor of Sir Arthur George Tansley – an English botanist and a pioneer in the science of ecology who introduced the concept of the ecosystem into biology.  Like Sir Tansley, Dr. Helm regards ecosystems as the basic units of nature in which a community of living organisms (e.g., plants, animals and microbes) in conjunction with the nonliving components of their environment (e.g., air, water and mineral soil), interact as a system. 

“Though the organisms may claim our prime interest, when we are trying to think fundamentally, we cannot separate them from their special environments, with which they form one physical system”

­Arthur George Tansley

Depending on the job (biological consulting or wetland construction) Tansley Team, Inc. does business as (dba) as Helm Biological Consulting (HBC) or  Wetland Establishment Team (WET), respectively.

Firm Founder and History
Dr. Brent Helm is a wildlife biologist, botanist, and ecologist specializing in wetlands. He received a BS at Humboldt State University in Wildlife Management, emphasizing Botany, with a minor in Fisheries in 1988. His first consulting job occurred in the spring/summer of 1989 conducting rare plant surveys for EIP Associates on the Highway 65-Lincoln Bypass Project. The work intrigued Mr. Helm such that he sought and accepted employment at Jones and Stokes Associates (JSA – now known as ICF) in the fall of 1989. Always having a penchant for biological knowledge, Mr. Helm resumed his college studies at the University of California, Davis (UCD), while working nearly full time at JSA as the botanical and wetland functional group manager. Perhaps Mr. Helm’s most notable contribution to the JSA firm was his pioneering work with federal-listed large branchiopod (e.g., vernal pool tadpole shrimp and vernal pool fairy shrimp) life history, ecology, and occurrence mapping. Mr. Helm graduated UCD with a MS in Ecology in 1996. Mr. Helm left JSA in 1997 to pursue the challenges of a small startup biological consulting company (May Consulting Services [MCS] - now known as May & Associates, Inc.). During his time with MCS, Mr. Helm expanded the company’s qualifications and employees and completed a doctorate in Ecology in 1999 from UCD.
Shortly after his departure from MCS, Dr. Helm founded HBC in 2001. The firm prides itself on technical expertise and efficiency. It is not uncommon for HBC to inherit projects that other consultants were unable to complete. In response to the growing need to implement wetland restoration, enhancement and construction work, Dr. Helm received his State of California General Engineering Contractor A license in 2009 and founded his second company - Wetland Establishment Team (WET) the construction division, specializing in the development of wetlands.

In 2009, Dr. Helm incorporated the two companies HBC and WET, under the name Tansley Team, Inc. The firm was named in honor of Sir Arthur George Tansley – an English botanist and a pioneer in the science of ecology who introduced the concept of the “ecosystem” to biology. 

Depending on the project (biological consulting or wetland construction) Tansley Team, Inc. does business as (dba) Helm Biological Consulting (HBC) or Wetland Establishment Team (WET), respectively.
