Forest carbon surveys quantify carbon in above-ground trees and in detrital pools of forest floor, woody debris, and soils.  The data can be used to parameterize simulation models to see how much carbon can be stored.

Stream surveys are designed to assess stream conditions such as habitat for fish and aquatic organism or hydrologic function. Our surveys are very useful to help to design restoration projects. We perform surveys using a variety of established protocols or we can design specific protocols to address specific issues. We have experience using Forest Service Level II, ODFW Aquatic Inventories, Rapid Bioassessments, and culvert assessment techniques.

Fish surveys are performed to identify species presence/absence, composition, distributions, and relative numbers. We perform ODF/ODFW Upper Extent Fish Use electrofishing surveys for industrial timber companies as part of the project layout. We also do snorkel surveys for to assess relative numbers, species distributions.

Stream mapping is also performed to locate small stream systems that are not currently mapped on existing hydro layers or on USGS maps.

Other surveys such as fungi, wildlife, or sensitive species surveys are designed to assess presence and abundance.  


Scientific data analyses is one of our strengths. Our reports present the methods and findings and the interpretations of the data. We can provide a variety of quantitative analyses, statistics, graphical presentations, GIS services, and review of literature or existing data sets. We also provide scientific peer review and comment to draft documents.


Written documents can be reviewed or prepared.  CEQA and NEPA, summaries of meeting minutes, data synthesis, and original manuscripts for publication. 

Watershed analyses and assessment are performed for watershed organizations or land managers. These assessments can follow various established protocols such as the OWEB protocols or the Federal versions of watershed analyses.

Models for stream function, habitat, or carbon accumulations have been parameterized and run for a variety of projects.  Models include EDT, HEIwest, ROTHC, CENTURY, and our own forest carbon accumulation simulator.


Stream monitoring projects can be designed for effectiveness of restoration projects or for water quality or fish use.
