We monitored at Robertson Millpond Preserve on Friday and managed to avoid tripping on the many cypress knees that populate our monitoring locations. Robertson Millpond Preserve is unique in that it is home to the only bald cypress habitat in Wake County, NC. We didn’t find many salamanders at this site, but we did find a Green Treefrog and Pickerel Frog.
New Volunteers Get Their Feet Wet in First Round of 2023 Volunteer Wetland Monitoring

The first Volunteer Wetlands Monitoring Pilot Program weekend of 2023 provided plenty of opportunities to get our feet wet (both literally and figuratively)! We had lots of new people volunteering this weekend who got to learn our monitoring protocols for amphibian surveys, water quality sampling, and hydrology monitoring for the first time. We are so excited to see the program expanding and meet new, amazing wetland warriors!
On Saturday, we monitored at Mason Farm Biological Reserve in Chapel Hill, NC. Our first monitoring location was wetter than we’ve ever seen it! In some places the standing water was over a foot deep and some of us had to switch to waders to avoid overtopping our boots! Because of all the water, we were able to find lots of larval salamanders who would sneak up to the surface and make themselves visible in the otherwise dark or cloudy water. We don’t usually take a water quality sample at this site and don’t have a permanent staff gauge because it is often completely dry.
This site illustrates how widely wetland hydrology can fluctuate over the course of the year. Luckily, our water level data loggers will help us keep track of the hydrology even when we can’t go out and see for ourselves. These loggers, along with our keen observations of wetland hydrology indicators, such as, drift deposits and crayfish burrows can help us to determine whether our sites are really “wet” enough to be “wetlands.” Sometimes, when we visit a wetland during the dry season, it can be hard to know how wet it is at other times of the year. These indicators and loggers help us to have a clearer picture of wetland hydrology over time.
On Sunday, we had a beautiful monitoring session at Hemlock Bluffs Nature Preserve. We were lucky enough to be joined by an employee of the preserve who says she can “smell where the salamanders are.” We were able to find salamanders in every life stage from egg sacks to adults, although the numbers that we saw may have been impacted by other herpetology surveys in our study area earlier in the week.
It was great to see so many new faces and add to our already wonderful group of wetland warriors. We are looking forward to getting back out in June for another round of water quality, hydrology, and amphibian monitoring. We will also be doing our vegetation surveys, so we’ll be calling all plant lovers for our next monitoring events. In the meantime, we hope to see everybody at our second Wednesday of the month Meet & Greet social events and to get back in the wetlands soon for some more practice with our field skills.

Wetland monitoring is important not only for the data we collect, but also to provide hands on education about why wetlands matter. Wetlands can provide so many benefits to humans and the environment, including creating habitat , flood reduction , filtering out pollution , settling sediment, storing carbon, recharging aquifers that we rely on for drinking water, and providing recreation opportunities for humans ! While not every wetland provides all of these services, this March we experienced many of these benefits during our monitoring visits. Habitat Wetlands provide important habitat for many species. This spring we conducted amphibian surveys at each of our sites and saw lots of amphibians! Wetlands are very important for the lifecycles of many amphibians who live in them, rely on them for food and habitat, or use them as nurseries to lay their eggs and protect their young. Unlike lakes and streams, ephemeral wetlands are not wet year-round. The periodic drying of surface water in these wetlands prevents them from being habitat for fish which may eat young salamanders. Our spring wetlands made a great nursery for amphibians and provide habitat for adults as well. We saw: mating American toads spotted salamander egg masses larval marbled salamanders northern cricket frogs a southern leopard frog upland chorus frogs northern dusky salamanders southern two-lined salamanders There were also several frogs that we couldn’t catch a picture of fast enough to identify.
