Montana Tubifex Summary by River System

river systems affected by Tubifex tubifex

This section will provide a simple summary of my Tubifex sampling effort and results that are organized by drainage. These will be interpreted results including comments on sample quality, adjustments for sampling season, notes on the condition of the invertebrate community, general observations and comparisons with other sites. Sample code numbers are included to make it easier to double-check and update the results in the future. The most updated raw data are available by clicking on the sample locations of the Tubifex Sites and Status Maps.

I will include some conservative interpolation and extrapolation of the data based on my experience. I will try to identify some research and management opportunities. I will also identify gaps in the sampling effort to date and to fill them as soon as possible.
