How do you build a portfolio of conservation sites for the Hawaiian Ecoregion?
The TNC Ecoregional Assessment Process
Building an Ecoregional Portfolio
Ecoregional assessments conducted by The
Nature Conservancy run through a standard set of steps that culminate
in an "ecoregional portfolio," a set of sites designed to
collectively conserve the biodiversity of an ecoregion. This
ecoregional assessment website is structured to follow that process:
- Identify conservation targets at a variety of scales, that represent the overall biodiversity of the ecoregion.
- Assess viability of conservation targets by analyzing their size, condition and landscape context.

- Establish conservation goals
explicitly in terms of numbers, area, or percentage of viable
conservation targets sufficient to effectively conserve the
- Establish a portfolio of sites comprised of conservation areas that
express the accumulated goals across the ecoregion, ensuring representation and redundancy of viable
- Define action sites -- a subset of the portfolio, at which highest priority efforts will be focused.
- Assess critical threats to portfolio conservation targets, particularly those effecting action sites.
- Develop strategies to
abate critical threats and maintain or improve viability of
conservation targets, through conservation actions such as acquisition,
adaptive management, and establishment or change in policy. Ensure a
system of monitoring of conservation progress.
