• What percentage of BLM’s
streams and rivers are in
good, fair or poor biological
condition?
• What is the risk posed by
the observed stressors to
biological condition?
• Public Land Statistics
reporting
• Regional mngt. priorities
NAMF: National scale example - WRSA

WRSA: How were sites selected?
Survey design:
1. Target population = NHD streams and rivers on
BLM lands (lower 48; wadeable + non-wadeable)

WRSA: How were sites selected?
Survey design:
1. Target population = NHD streams and rivers on
BLM lands (lower 48; wadeable + non-wadeable)
2. Probability-based
design (GRTS):
~350 sites
a. Intensification of
EPA NRSA (50+
BLM sites)
3. Stratified by hybrid

EIFO: How were sites selected?
Survey design specifics:
1. Probability-based design
2. Target population
• Wadeable perennial
streams and rivers
3. Stratified by mngt. Unit (x3)
• Provide sufficient
accuracy and precision
at mngt. level
• Goal: 65 sites sampled
between 2014 – 2016
4. Targeted sampling of
reclaimed sites
• N = 15+
