This is the time of year when we start thinking about our lawns and gardens. Before we know it, the dry season will be upon us and our lawns and gardens will be getting thirsty. This is a great opportunity to have a Salmon Friendly Lawn and all you have to do is nothing. Don't water your lawn or use chemical herbicides or pesticides in your yard. Let your lawn go brown this summer. It will green up again with the Fall rains. 

How does this give you a Salmon Friendly Lawn? The water from our taps comes from either rivers and creeks or groundwater wells. Up to 40% of the water we use in summer is for watering our lawns. By not watering your lawn you leave more water in the rivers and creeks for juvenile salmon, when the water is needed the most. Also, creeks and rivers are fed by groundwater in the summer so the more water left in wells means more water in the creeks and rivers to support salmon. Chemical herbicides and  pesticides are harmful to fish and enter creeks and rivers through stormdrains or directly off the land.

yellowfish3MVIHES is promoting Salmon Friendly Lawns through a Yellow Fish program, where residents who pledge to not water their lawns or use chemical herbicides and pesticides will get a groovy yellow fish sign to show off to the neighbours and help promote the message of conserving water. The sign comes with a decal stating "brown is the new green" which makes having a  brown lawn not only a great thing for salmon but states you're a cool trend setter and influencer.  To take the pledge for a yellow fish, contact us at This email address is being protected from spambots.

If you're interested in going the extra mile, rain barrels are a great option for watering trees, shrubs, vegetable and flower gardens to reduce tap water use even further. The  City of Parksville offers rebates for purchases of rain barrels. Check out the awesome brochure on rain barrels by Team Water Smart at the Regional District of Nanaimo.

Other things you can do to help your lawn remain healthy and reduce its watering needs are:                 

  • Mow your grass high (5 – 6 cm) and leave the grass clippings. Taller grass means less run-off, and healthier lawns. Healthier lawns are less likely to grow weeds.
  • Aerate your lawn and top-dress with compost to help rainwater penetrate deeper into the roots where it will do the most good and improve water retention.                                       

  You can make a difference.

Pacific Sand Lance Storm the Beaches of Parksville

2021 was the best year yet for documenting Pacific Sand Lance spawning on our shores!

Sand Lance are just one of the forage fish species that travel in large schools and make up the cornerstone of marine food webs. Pacific salmon are just one of the predators of forage fish.

Sand Lance lay tiny eggs (1mm) on pebble and sand beaches just below the high-tide line - an area called the intertidal zone. Spawning occurs between November and February at high tide. It has been suggested the fish prefer full and new moons, when high tides are at the highest and providing maximum area for spawning.  At low tide, MVIHES volunteers visit the beaches from Craig Bay to Columbia Beach to collect sand and gravel samples to see if they contain eggs. Samples are collected from plots set up in the intertidal zone of established monitoring sites. The photo below shows a plot which has been set up with measuring tapes.

A plot is 5 m wide and runs for 30 m along the beach. Samples are seived and "vortexed" (a process similar to gold panning) to sort out the smallest and lightest grains on which eggs are typically found.

The sorted grains are placed under a microscope at Vancouver Island University (VIU) where the Forage Fish project leaders at the Mount Arrowsmith Biosphere Region Research Institute (MABRRI) check for eggs. The photo on the right is a microscopic view of Sand Lance eggs in a sample taken on December 13 from one of our beach monitoring locations in San Pareil. So far this season, eggs were found in our samples at the following locations:    

Craig Bay on December 1

San Pareil on November 17, December 1, and December 13

Community Park Beach on November 29 and December 13

French Creek Marina on November 29

 

 So why is it important that Sand Lance spawning sites be documented?

Our actions on and around these beaches, like shoreline development, can have negative impacts on forage fish spawning success so it is important to know where and when these fish spawn. Work by heavy equipment should be avoided on Sand Lance beaches between November and February. Unfortunately, this is the season when serious damage occurs to shoreline property and homes that require urgent repairs, as we have seen in the local news. A lot of the damage to property and homes can be avoided if shoreline development is conducted using ecologically sound practices. Best of all, these practices can help conserve the spawning habitat that is currently being degraded by retaining walls and other hard shoreline structures.

Green Shores is a program that is gaining popularity for making shorelines more secure against flooding and erosion and restoring shoreline ecological function for species like Pacific Sand Lance. Below is a figure from the Green Shores website that highlights the difference between standard and Green practices.
