The spring field season has begun with a 10-week study on migratory fish in the York River. We are collecting data for the Wild and Scenic Study Committee by using fyke nets to sample fish every day.

Rainbow Smelt in the hand. Caught in the York River in early April 2017.We started work in the beginning of April and in the first three weeks caught 2,598 fish, of which 1,228 were spawning rainbow smelt. We recorded the length, weight, and sex of each smelt caught, finding the average fish to be 6.1 inches long and weighing about 1 ounce. More than 87 percent of our catch was male. Males usually arrive first at spawning sites and wait for females. They can also travel up river to spawn more than once during the spawning cycle, while females will swim upstream and spawn in one high tide event.

Brook Trout in the hand.This spring, our research staff will be heading out to nearby rivers to begin a fish-monitoring project and you can get involved.

We're collaborating with the Maine Department of Marine Resources (DMR) to generate up-to-date population information on species with the greatest conservation need in coastal Maine. DMR staff have identified potential spawning habitat for diadromous species such as alewife, rainbow smelt, and brook trout in the Merriland River, Mousam River, and Little River (Biddeford). Now we’re off too see if these species are indeed using these habitats.

 We've processed all the catch from another season of trapping green crabs (Carcinus maenas) and have some preliminary results to report.

Between June and October we caught 6,432 green crabs. This is merely half the number of crabs as last year! In the figure below you can see that the catch was not distributed equally across the three trapping sites. Trends in numbers were similar to those seen last year. Again, the most crabs were caught in the Webhannet River, Wells (3,848) and the least in Broad Cove, Yarmouth (284).

WELLS, Maine, September 21, 2015 — On September 18, a small dam was removed from Goff Mill Brook in Arundel near where it flows into the Kennebunk River estuary. The removal reconnects seven miles of stream habitat to the estuary, benefiting brook trout, other migratory and freshwater fish, and the watershed’s ecology. The project was coordinated by the Wells National Estuarine Research Reserve, working in full partnership with the Sebago Chapter of Trout Unlimited under TU’s national Embrace-a-Stream grant program.

“Goff Mill Brook is now connected to the Gulf of Maine for the first time in at least 60 years,” said Wells Reserve project manager Jake Aman. “We expect many fish and wildlife species to benefit from this restoration, including commercially important fish like American eel and river herring.”

Crab TrappingAs an environmentalist, I'm interested in the relationship between human communities and their environments. That is, how human activities have impacted watershed environments, coastal ecologies, and others alike. The opposite perspective is also how environmental changes such as climate change and sea level rise are affecting human communities especially in coastal regions. I want to learn more about these environmental issues and explore the possibilities of conservation techniques that could benefit both sides.

As a research intern at the reserve this summer, I was keen to discover more about these topics with NOAA and how relevant it was to my past research opportunities. I have been involved in several different projects that are tide-dependent and require different monitoring/research skills.

Back in September we reported on a current research project going on at the reserve — green crab sampling! We now have an update on this project, but first to refresh your memory…

Over the 2014 field season, research staff and interns participated in a green crab abundance study in hopes of getting a better understanding of population dynamics of this invasive species on marshes along the coast of Maine. We used modified eels traps baited with Atlantic herring, deployed two traps at a time per site, left them for 24 hours, and repeated this process eight times between June and October.

Group photo of 'blue carbon

WELLS, Maine, December 8, 2014 — Scientists from around New England met at the Wells National Estuarine Research Reserve on December 5 for a workshop focused on “blue carbon” science and policy. For the first time, scientists from throughout the region gathered to share research results, identify gaps in knowledge, and plan future collaborations involving carbon in coastal habitats.

The term “blue carbon” refers to the ability of salt marshes, seagrass meadows, and mangrove forests to take up and store carbon dioxide and other greenhouse gases from the atmosphere. Coastal wetlands capture carbon and store it at rates even greater than rainforests.

“Carbon held naturally in coastal wetlands is not entering the atmosphere as a greenhouse gas, so these habitats have real potential to mitigate climate change,” said Dr. Kristin Wilson, Wells Reserve research director, who co-coordinated the workshop.

Measuring a green crabThe invasive European green crab is not only a popular topic in the media these days; here at the reserve green crabs are receiving their fair share of attention as well — 5,878 of them so far to be exact!

The Wells Reserve has teamed up with the University of Maine, Casco Bay Estuary Partnership, and Southern Maine Health Care to study the impacts of the invasive European green crab (Carcinus maenas) on the geology and “stability” of our marshes. Over the summer we have been collecting abundance data that will later be used in conjunction with fyke net data, water quality data, and even geological techniques to better understand the effects green crabs are having on salt marshes throughout southern Maine.

The Sounds of Place

Purdue University ecological acoustics research team on a cool, damp, May dayLast week we set up acoustical equipment in 12 locations throughout the reserve, typically about 40 feet off the trails. The equipment will create an ecological soundscape of habitats… mapping sounds of animals and other living things (biophony), sounds coming from wind in the trees, rain, and the ocean (geophony), and sounds of jet planes, people talking, trains, gunshots, and lawnmowers (anthrophony). Together, these recordings will help describe our environment over time… who is there, who is missing, what is disturbed, what has changed.

Will these soundscapes reveal habitats of vitality or quiet? What changes happen over time? Is the food web diminishing or increasing with new animals, returning animals? Are the sounds different from year to year, day to day, month to month, season to season?

asdfIn his recent post, Spreading the Fish Ladder News, Jake mentioned our imminent use of passive integrated transponders, or PIT tags, to track fish. But just what is a PIT tag and exactly how does it work?

A passive integrated transponder is a miniature electronic circuit typically encased in glass and implanted under an animal's skin or in a body cavity (the fish tags we'll use are thin and just 12mm long). Each tag is programmed with a unique number to identify an individual animal. That number is read automatically when the animal travels close to a receiving station.

Goal

Develop a disaster response plan for the Wells Reserve and surrounding watersheds that complements and coordinates with local and county efforts and that will serve as a model for other natural resource organizations and agencies.

Bridge washout on Skinner Mill Road due to 2006 Mother's Day stormWhy Do This Project?

The Julie N oil spill in Portland Harbor (1996), Mother's Day storm (2006), and Patriot's Day storm (2007) caused extensive environmental and infrastructure damage to the coastal areas of southwest Maine. More recently this region was narrowly spared the great devastation caused by Hurricanes Irene (2011) and Sandy (2012). These events have reinforced that:

  • the occurrence of natural and man-made disasters is unpredictable
  • a lack of preparation can result in a slower and less efficient response
  • resilience of natural resources and man-made infrastructure to disasters can be "built in" in advance to some degree

Hi Everyone,

Thought I would share some numbers from our System Wide Monitoring Program (SWMP) weather station here at the Reserve, and compare them to some values from around the area. First off, it seems we got "lucky" with rain fall totals. Both the Reserve station and the Portland International Jetport weather station reported just over an inch of rain on Tuesday. However rainfall totals varied a bit depending on where those "bands" of precipitation hit… pretty minor event as far as actual rainfall goes, but when that rain is being blown sideways at close to 60mph.

Back in July, Wells Reserve staff and interns teamed up with volunteers from the Sebago Chapter of Trout Unlimited and bravely struck out on an ambitious survey of road-stream crossings in the Kennebunk River, Merriland River, and Branch Brook. The teams worked hard and surveyed an amazing 81 road-stream crossings in only three days!

Perched culvertI led one of the survey teams and let me tell you, that data was hard-earned! Once we had located a crossing, we had to battle thick brush, mud, poison ivy and steep slopes of riprap to reach the stream. To measure the length of a crossing, we sometimes had to crawl through a culvert from one end to the other, dodging spider webs along the way. Besides being a fun excuse to go crashing through woods and splashing through rivers, this survey was an important way to gather data that will be used by town planners, landowners, conservation groups, and other stakeholders to reconnect stream habitat in these watersheds.

The Shoreys Brook dam came out in November 2011, and since then the brook has been steadily carving its way through the sediment that has collected for over a century in the impoundment. Vegetation is starting to take hold in places, but it will be a few years before it begins to look like anything but a large mud pit. As old sediment flushes away, older substrates begin to emerge along the stream bottom, showing signs of what the brook once looked like. Gravel, cobble stones, and even boulders can now be seen littering the stream, which is a positive sign for the restoration team. Rainbow smelt are looking for just this type of stream bottom to lay their eggs on in the early spring.

Project Summary

Researchers manipulated densities of the invasive snail Littorina littorea at two sites, one in the Little River estuary and another in the Webhannet River estuary, to investigate the effect of grazing on plant production and sediment accumulation. They found that under more stressful conditions for saltmarsh cordgrass (Spartina alterniflora) – poor drainage or greater flooding, for example – the impact of snail grazing on biomass becomes apparent: Where snails eat cordgrass faster than it can grow back, less cordgrass is available to capture sediment and the marsh surface does not build up as quickly. In contrast, the impact of snails is not significant under more favorable conditions for cordgrass.

Project Description

Red tide — the proliferation of several toxic algal species — has been affecting fish and shellfish fisheries in Maine for decades. People who eat clams or other organisms exposed to toxic algal blooms can suffer from amnesic or paralytic shellfish poisoning, conditions with symptoms such as short term memory loss, vomiting, disorientation, paralysis, and sometimes death. Early detection of harmful algal blooms is critical for protecting fisheries, resources, and public health in Maine and worldwide.
