HSI Calculator

15 Jan 2016

The great crested newt Habitat Suitability Index (HSI) has long been used by ecologists to assess waterbodies in terms of their suitability as aquatic habitat for the UK’s largest and most heavily protected species of newt. In the time since its development by Oldham et al. 2000, and its publication in Herpetological Journal, completing an HSI assessment has required numerous steps including:  gathering of field data, consultation of multiple graphs and the manual running of several calculations in order to obtain a final value and subsequently an appropriate classification of a waterbody’s suitability for the species. This article presents a new tool capable of automatically calculating HSI scores when provided with ten variables currently required of the assessment.
