Volunteers on the Go

Welcome to the first in a series of "Volunteers on the Go". Our volunteers are proving very resilient by continuing to do MVIHES work while following the recommendations of BC's health officers in fighting COVID-19 (i.e. no hugging and kissing allowed). Here are a couple of the things we are doing.

Photo Point Monitoring

Michael

 

 

Michael Castonguay has been conducting photopoint monitoring on the Englishman River for over a year now. This involves taking photos along the river in precisely the same locations every few months so that changes in the river banks, gravel bars, log jams, etc. can be tracked. It's important for understanding the power of the river and the dynamics of the river channel. 

 

 

 

  

 

Below are some examples of how the river changes with the seasons.  The first two photos were taken looking upstream from Top Bridge and the next two photos were taken looking downstream of Top Bridge. The left-hand photos were taken in June 2019 and right-hand photos in February 2020. Some landmarks have been added to the photos so comparisons can be made of the water levels.

I'm sure the people lounging on the gravel bar were gone before the winter rains arrived...pretty sure.  The pictures below were taken in June 2020,  and show what the high winter flows are capable of. The photo on the left  shows the remains of a woody debris structure that was constructed using large logs and stumps anchored with cables to boulders on the shore. If you look closely, you can see one of the cables. The purpose of the structure was to create pools and shade for fish. Chewed up and spat out by the river it was meant to help. The photo on the right shows a chunk of the stream bank that was eroded off and moved into the stream channel, trees and all. The lesson here is: don't mess with Mother Nature. Thank you, Michael, for capturing these great images.

Wetland Monitoring Program

The next photos were taken in June 2020, and show a wetland survey in progress in the CW Young Side Channel in the Englishman River Regional Park. The Side Channel provides rearing habitat for Coho Salmon fry. The wetland was created by beaver dams in the Side Channel.  Pete  Law and Barb Riordan are in the photo on the left. Notice the nice social distancing. Pete and his canoe are in the far right  photo, and Jim Goodwin is in the middle. Jim is with the Arrowsmith Naturalists and is conducting bird surveys as part of the wetland survey.  Two small colonies of yellow iris, an invasive species, were discovered in the wetland in 2018. The Regional District of Nanaimo Parks Department (RDN) arranged for the yellow iris to be removed by the Coastal Invasive Species Council, and asked MVIHES to monitor the wetland for other colonies of invasive species for five years, starting in 2019. An article summarizing last year's monitoring is available here. This year's survey is not yet complete so there are still opportunities to  participate.

 Upcoming Projects

1. Stream flow monitoring in the Englishman River using a FlowTracker. We will measure the flow in the ER by taking a series of velocity measurements through the cross section of the river at different locations. These measurements are combined with water depths along each cross section to calculate flow rate (m3/second). This involves wading in the river so chestwaders with felts are recommended.

2. Annual water sampling of the Englishman River and its tributaries. This Includes weekly sampling for five weeks in August and again for five weeks in October. We have nine sites where we collect data on temperature, dissolved oxygen, conductivity and turbidity. Some of these sites require travelling on logging roads with scenic vistas and take you to some very pretty spots.

3. Completion of the Wetland Survey mentioned above. This involves some hiking through the bush and wading through a marsh to access our monitoring plots.  We  have a few spare pairs of chestwaders if you don't have your own. We will be collecting data on the number of salmon fry we see and other wildlife, measuring water depths, and collecting information on the plants growing in the plots.

Lord of the Flies, Part Two

"Lord of the Flies" - MVIHES term for an expert in identifying aquatic bugs 

Some of you may remember last year's program of monitoring Benthic Invertebrates (fancy term for aquatic bugs) to measure the health of the Englishman River and its tributaries. The results are in and are summarized below.

Lordoftheflies1

 

The photo to the left shows Bruce Murray (standing), our own Lord of the Flies, leading volunteers in sorting Benthic Invertebrates collected from the river bottom into trays for identification by Bruce. In addition to MVIHES volunteers, members of the Island Waters Flyfishing Club in Nanaimo, a member of the Mid-Island Castaways Fly Fishing Club in Qualicum Beach, and students from Dover Bay Secondary School Field Biology Program, participated. 

                                                                                                                                             2019 - Volunteers Sorting Aquatic Bugs 

Lordoftheflies5

 

 

We used a method of sampling that has been around for a while, and anyone who has taken the “Streamkeepers"  course will remember it. We scrape rocks from the bottom of the river into fine meshed nets to capture the bugs, as shown in the photo to the right.

Bruce then strapped on a pretty impressive set of magnifiers to get a very close look at the features of the bugs to aid in their identification. Data on the types of bugs and their numbers were recorded. The bugs were then released back into the river.

 

 

 

Once all the bugs were identified, we used the  "Streamkeepers" method of categorizing  them  into the following three groups depending on their ability or inability to tolerate polluted  water.

  • Pollution Intolerant: Caddis Flies, Stone Flies, May Flies, Dobson Flies, Riffle Beetles. These species require clear, clean , well oxygenated water, as do salmon and trout. 
  • Somewhat Pollution Intolerant: Dragon Flies, Damsel Flies, Crane Flies, Aquatic Sowbugs, Alder Flies, Scud, Crayfish, Clams
  • Pollution Tolerant: Midges, Black Flies, Backswimmers, Boatmen, Leeches, Aquatic Worms, 

A river that has a lot of bugs that are intolerant of pollution is considered to be healthier than a river with more of the bugs that tolerate pollution.

A total of eight sites were sampled:

  • four in the Englishman River between the Englishman River Regional Park and the Orange Bridge in Parksville
  • one in the South Englishman River
  • one in Centre Creek
  • one in Morison Creek 
  • one in Shelly Creek

The sample site in Morison Creek had the highest abundance of bugs while the site at the Orange Bridge had the lowest abundance.

May Fly (left photo) was the dominant species at five sites while Caddis Fly (right photo) was dominant at two sites.  Both are Pollution Intolerant.

 

 

 

watermite

 

 

 

The Top Bridge sample site in the Regional Park was dominated by Water Mites which are a Pollution Tolerant species (right photo). Water Mites are the size of pepper grains, are NOT a human health issue, and provide a nice snack for young trout and salmon. Although the Water Mites were the most plentiful species at this site, the combined numbers of Pollution Intolerant and Somewhat Tolerant bugs were greater.

 

 

 

When we combine the bugs collected at all the sites, 78% were Pollution Intolerant, 4% were Somewhat Pollution Tolerant and 24% were Pollution Tolerant. When we look at the combination of bugs for the individual sites, we find that although there were more Pollution Intolerant bugs, two sample sites had enough Pollution Tolerant bugs to rate the sites as only "Marginal" and "Acceptable", compared to "Good" for the remaining six sites. The graph below shows the score for the sample sites based on a Pollution Tolerance Index.

This is certainly good news as it shows that in 2019, the Englishman River watershed appeared to be in reasonably good health, based on this study. The technical report can be viewed by clicking here.

This study was a major undertaking and would not have been possible without the participation of nineteen volunteers listed below.

Smolt Counting in a Pandemic

Badfish

 

Two of our diligent volunteers, Shelley and Carl, are conducting the annual Coho smolt count on Shelly Creek admidst the COVID 19 pandemic by staying 2 m away from each other.  The fish, on the other hand, are not behaving themselves at all.

 

 

 

MartindalePondEvery winter, flooding of the Englishman River sweeps Coho Salmon fry into the Martindale Pond (shown in the photo to the left),  a section of the creek upstream of Martindale Road in Parksville. The fry remain in the pond for the winter, sheltered from the turbulent flows of the Englishman River, where they develop into smolts in the spring. The migration back to the Englishman River begins when water temperatures increase and oxygen levels in the pond begin to drop.  

 

 

holysmoltssmoltfencesmall

Each spring, we set up the smolt trap in Shelly Creek to count the Coho Salmon smolts as they migrate out of the pond to the Englishman River and out to the ocean. The trap includes a fence that directs the fish through a pipe into a box where the fish are held until they are counted and released into the creek, as seen in the photos to the right. (All photos were taken before social distancing measures.)

The smolt fence and box were installed by  volunteers on March 15.

 

 

 

 

Normally, four to five people come to the the trap each morning to count the fish. But shortly after installation, the Province of BC advised people to self-isolate and conduct social distancing when around others to prevent the spread of the Coronavirus. MVIHES has limited the counting to two people, with one person recording data and a second handling the fish so that a distance of 2 m between volunteers can be maintained and equipment is not handled by more than one person. Not as much fun as previous years but if we all behave ourselves, this too shall pass.

 

countingsmoltThe fish have a completely different attitude. There were 172 of them packed into the box today! In fact, a total of 1,115 smolts have been counted so far and we still have a few weeks of counting to go. The average number of smolts counted in a season is around 4,000, with the 2013 and 2018 seasons having over 7,000 smolts, and the 2012 season having over 8,000 smolts. This demonstrates the importance of Shelly Creek to the Englishman River Coho Salmon stocks.

Smolts (and a red-legged frog) are netted from the box and placed in a tub to be  identified and counted.
