The oyster metrics are quantitative evaluation criteria
used to determine the restoration success of an oyster reef and tributary.
Three year and
six year monitoring efforts are used to assess the oyster metrics for each
reef. So far, at three year monitoring (2015-2017) 98% of reefs met the minimum
threshold success criteria for oyster density and biomass in Harris Creek. Oyster
monitoring reports can be found here:

interactive map with the restoration reefs in the Harris Creek sanctuary. The
legend and layers are located in the upper right hand corner. You can click on
a reef to see more information. The information was last updated in 2018.
sites are identified as ‘seed only’ restoration (hatchery-produced
spat-on-shell added to existing remnant reefs) or ‘substrate + seed’ restoration
(adding reef-building substrate to the reef footprint, followed by planting
with hatchery-produced spat-on-shell) or ‘premet’ (sites that already meet the
Oyster Metrics target oyster density (50+ oysters per m2) and oyster
biomass (50+ grams per m2) and did not receive initial restoration).
