Designing a state-wide volunteer monitoring

Paul C West--August, 2003—Citizen Monitoring Conference

The mission of The Nature Conservancy is to protect the

plants, animals and habitats that represent the diversity of life on

earth by protecting the lands and waters that they need to survive.

Measuring Success

• Volunteer monitoring examples

• Use of the monitoring data

• What to monitor

• Recommendations

Outline

Nature Conservancy monitoring programs

• Inform public policy or DNR priorities?

• Guide site-specific management actions?

1. Develop state-wide monitoring objectives based on conceptual models and key driving factors

Recommendations

Example: Between 2005 and 2010, we want to have a 90% probability of detecting a 10% change in [water quality, invasive species] and are willing to accept a 1 in 10 chance that we’ll say that a change occurred when it really didn’t.

Key components: timescale, chance of detecting change, minimum detectable change, what to monitor chance of detecting a false change

2. Monitor both target-based and threat-based monitoring (and possibly management-based, such as voluntary BMPs).

3. Focus on limited data at greatest number of sites

reduce observer bias

use for trend analysis to guide policy and budget decisions

complement detailed monitoring at fewer places, done by DNR and others.

4. Data management structure needs to be developed prior to collecting data.

Recommendations

5. Citizen-based monitoring should complement a comprehensive monitoring program

Recommendations

Landscape metrics: Overall extent; distribution, patch size

GIS-based Public agencies, possibly NGOs

Presence/absence or abundance of species; threat indicators

Field work Citizens, NGOs, public agencies

Community-level monitoring, eg., species inventory

Field work Public agencies; possibly NGOs
