Abstract:
This method develops a local environmental stewardship indicator (LESI), which represents the level of stewardship action of a person at a place. The goal of the indicator is to quantify stewardship activity and allow it to be compared and modelled. LESI requires a brief interview to ascertain an individual's past and current stewardship activities, which are scored on a frequency scale for each of seven action categories. Scores are then combined using the LESI equation to: • Quantify reported stewardship behaviour (as opposed to attitudes or intentions) as a single number. • Enable comparisons of stewardship between individuals and places. • Allow development of models to understand the predictors of stewardship, and • Inform evidence-based strategies for stewardship improvement.

Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks...
