Forestry Environmental Services

WEST brings together a broad group of ecologists and biometricians that have a wealth of experience working with issues pertinent to the forest industry. Our environmental professionals have extensive experience in designing and conducting field surveys for many forest dwelling/dependent species as well as analyzing and interpreting the data associated with such surveys. We offer top level specific scientific expertise; statistical prowess that ensures excellent design and analysis of field surveys; and experience in specialized environmental facilitation and mediation of technically challenging issues. We endeavor to provide high quality data and defensible analyses that are accepted by all parties.

Our staff includes several scientists who work directly with forest species. The WEST team has a working knowledge of numerous listed and/or sensitive forest species and are familiar with the techniques necessary to study rare and uncommon wildlife and plants. Additionally, our staff are recognized nationally for rigorous, objective and transparent scientific syntheses and reviews, including a large-scale analyses on forest dependent threatened and endangered species in Oregon. WEST also has a knowledgeable Geographic Information Systems (GIS) staff that can aid in both the design and analysis of projects that incorporate large sets of spatial data.

Combining Statistics & Ecology


WEST develops and implements studies for forestry projects that result in defensible statistical inferences. Examples include: predicting marbled murrelet occupancy based on habitat use models and field survey data; and analysis of northern spotted owl population trends on managed timberlands.



Representative Staff Experience

  • Field studies of spotted owls in California, Oregon, Washington, Arizona, and New Mexico (occupancy surveys, nest monitoring, banding, telemetry).
  • Demographic analysis of northern spotted owl on managed timberlands in California.
  • Surveys for marbled murrelet (ground based-observation and radar surveys).
  • Modeling of marbled murrelet habitat use (e.g., predicted occupancy by murrelets based on field survey data).
  • Red tree-vole studies (nest surveys, nest monitoring, genetic sample collections).
  • Bat use studies (roost tree characteristics, acoustic surveys, radar surveys, telemetry).
  • Aerial Surveys: extensive use of helicopter and fixed-wing aircraft to conduct surveys for big game, game birds, raptor nests. Design and analysis of aerial survey data.
  • Songbird and raptor capture, banding, telemetry.
  • Big game studies: field studies (capture, telemetry, remote-cameras) and data analysis (resource selection modeling, population modeling, habitat use, migration routes).
  • Fisheries field studies (streams, lakes, reservoirs) and quantitative analysis of fisheries data.
  • Herpetological field studies (aquatic and terrestrial amphibians and reptiles) and analysis of amphibian monitoring datasets.
  • Botanical surveys and reclamation/mitigation monitoring.
  • Biological Assessments (BA), Environmental Impact Statements (EIS), Environmental Assessments (EA), and Habitat Conservation Plans (HCP).
  • Impact Assessments: analysis of predicted impacts based on quantitative analyses.
