Tools

SimAssem is a tool for investigating the performances of species richness estimators across widely ranging assemblages and survey designs. SimAssem also processes existing encounter data and formats existing and simulated encounter data for other programs. SimAssem, along with the open source code, will hopefully give researchers and managers a tool for assessing the development of new estimators and evaluating potential decisions in a simulated environment.
ERMit is a web application which models erosion on current or proposed forest road. ERMiT allows users to predict the probability of a given amount of sediment delivery from the base of a hillslope following variable burns on forest, rangeland, and chaparral conditions in each of five years following wildfire. The model also predicts the effectiveness of sediment mitigation methods following a wildfire, such as applying mulch or seeding.
Tahoe Basin interface is a customized version of Disturbed WEPP that contains Tahoe-specific soils. It predicts not only runoff and erosion, but also delivery of phosphorus and fine sediment, something of particular concern in the Tahoe Basin.
The Forest Service Peak Flow Calculator predicts peak flood flow rate for a given storm from a small watershed. The model uses Curve Number technology given precipitation and runoff, as from ERMiT, plus other parameters.
The Water Erosion Prediction Project (WEPP) is a computer simulation that predicts soil erosion.  This particular version of the tool predicts soil erosion for the Great Lakes watershed.
VAR stands for Values-at-Risk. The VAR Calculation Tool aids with assessing post-fire values-at-risk, including but not limited to human life and safety, infrastructure damage, and environmental effects.
RMRS Raster Utility is an object oriented coding library that facilitates a wide range of spatial and statistical analysis using our newly developed Function Modeling framework. Our library focuses on significantly reducing processing time and storage space associated with analyzing large datasets and has an easy to use graphical user interface, packaged as an ESRI add-in toolbar.
Disturbed WEPP is a web application which allows users easily to describe numerous disturbed forest and rangeland erosion conditions. The interface presents the probability of a given level of erosion occurring the year following a disturbance. Version 2.0 needs no vegetation calibration.
WEPP:Road predicts the annual average erosion from insloped or outsloped forest roads and predicts the amount of sediment that will leave the buffer.
The Arc Habitat Suitability Index is a geographical information system (GIS) model that estimates the ability of an area to meet the food and cover requirements of an animal species. ArcHSI is a tool intended to inform planners of the probable impacts on wildlife for the alternatives they develop. It is a tool that should augment, not supplant, the expertise of resource specialists with site-specific knowledge.
