How is population density of tiger measured
  • 1 answers

Gaurav Seth 4 years, 11 months ago

Sometimes, for certain ecological investigations, there is no need to the absolute population densities. Relative densities serve the  purpose equally well. In this case, population size is indirectly estimated without actually counting them. For example, the number of fishes caught per trap is good enough measure of its total population density in the lake. The tiger census in our National park and tiger reserves is often based on pug marks (animal's ft print ) and fecal pellets.
