1)
Fish
Fish are sampled using minnow traps three times during the summer.
Learn how to identify typical salt marsh fish species that use
wetland sites along the North Shore.
2)
Aquatic Macroinvertebrates
Invertebrate field sampling includes auger samples of the creek
bed, dip net samples of the vegetated creek bank edge, and quad
sampling on the top of the bank. Samples are preserved, sorted
off site and then identified under the microscope to family level.
. The presence/absence of particular family groupsas well as population
size can be used to assess the health of a wetland.
3)
Vegetation
Plants are identified generally in August to assess plant diversity
and overall health of a wetland as well as the presence or absence
of invasive species. Vegetation is sampled using established transects
and quads.
4)
Salinity
Shallow ground water wells are installed along three transects.
Eoverall health of a wetland. Refractometers and/or water quality
meters are used to take salinity measurements. This parameter
is important in explaining the dynamics of wetland water chemistry.
5)
Tidal Influence
Tidal restrictions are measured using staff gauges and tape measures
as well as how the patterns of tidal range and water depth affect
the viability of a wetland
6)
Land Use
Maps and aerial photography along with field techniques to describe
land use and the environmental characteristics of the landscape
are used to gain an overall measure of human disturbance at a
particular wetland site.
7)
Avifauna
Birds are used as bioindicators for the salt marsh habitats. The
presence/absence of certain bird species may provide clues about
the fish and invertebrate populations in the salt marsh. Field
identification is necessary.

tides, and creatures that have adapted to varying conditions. It is
a good source for fun activities to do with kids interested in marine
biology and a good storybook too.
