} An intensive short term (1-2 day) survey effort to collect
and identify species
} This effort used several different sampling techniques:
- diver collection
- plankton tows
- fouling surveys
- crab traps

} assess marine biodiversity and detect
introduced species
} plates suspended underwater from
docks and serve as passive collectors for colonization by marine invertebrates
SLIDE 6
} Results:
- No new NIS were detected in any of our surveys
- Species composition of the fouling community similar to
previous studies
- only cryptogenic species the bryozoan, Fenestrulina
delicia, found in previous fouling surveys

engage the public in marine invasion science
} provide training to citizen scientists } presentations } experiential learning in:
basic taxonomy, target species, field work protocols, and data recording
SLIDE 8
} Results:
- Provided a broad overview of invasion science and
specific training for identification and detection methods for target NIS relevant to PWS
- training to help RCAC implement a zooplankton
sampling program, which aims to detect target NIS in PWS using genetic tools

} Monitoring and sampling training } Rapid survey of fouling communities of Valdez Marina } Surveys included
settlement plates crab traps rapid assessment of dock structures
SLIDE 10
} Results:
- The bioblitz rapid surveys in the marina
yielded no NIS
SLIDE 11
} The European green crab introduced to the west coast of
California in the 1990’s
} steadily moving northward along the coast } most recently detected <100 miles from the Alaskan border } Six traps, 3 minnow (juveniles) and 3 collapsible (adults)
deployed in the subtidal at the Valdez Marina
SLIDE 12
} Results:
- Crab trapping yielded native crab species only, in both
minnow and collapsible traps
SLIDE 13
} dive surveys examined man-made maritime infrastructure in
high transit areas and
} Expanded the survey area assessed with settlement plates } Dive locations included:
- Valdez Ferry dock
- Valdez Container
- Terminal pilings
- Tatitlek Ferry dock
SLIDE 14
} Results:
- Only one NIS
the non-native bryozoan Schizoporella japonica
SLIDE 15
The bioblitz and training activities served multiple purposes
} Rapid surveys to detect target NIS } overview and training on NIS detection for a diverse
audience
} initiate a zooplankton sampling program } fouling community plate surveys in Valdez
