A parallel effort called the Montreal Process began among the United States and other countries with temperate and boreal forests. The Santiago Declaration of 1995 was an outcome of that working group. The declaration actually lists seven criteria of sustainability and 67 indicators. As mentioned earlier in this conference, criteria are goals or categories. They reflect broad public values and recognize scientific principles.
Indicators are measures that quantify or qualify a specific criterion.
Indicators can be remeasured at intervals to track changes in environmental, economic and social conditions. Finally, the entire suite of indicators is to be taken into consideration when evaluating sustainability. The first five criteria have indicators that are easy to quantify and include measures that we are most familiar with, like area of forestland and numbers of threatened and endangered species. Criteria 6 and 7 generally contain more indicators that are measured qualitatively. Indicators are more than just data.
