The Linear Density Index calculator computes the density of an individual species in a sample length.  The equation takes the total number of individuals of a species collected divided by the total length of all transects sampled.

INSTRUCTIONS: Choose the preferred length units and enter the following:

• (n_i)  This is the total number of individuals of species collected
• (L)  This is the total length of all transects sampled

Linear Density Index: The calculator returns the linear density index in units of individuals per meter.
