Happy Earth Day! Our neighbours at the Central Kootenay Invasive Species Society wrote this fantastic blog piece, so we thought we’d share (see original blog post at the CKISS website):

Earth Day started in the US on April 22, 1970 as an idea for a nation to focus on the environment. Today 192 countries and 1 billion people partake in Earth day events, a day of action that encourage change in human behavior in order to create a healthy and sustainable environment.

Make yourself part of the movement by preventing the spread of invasive species. Invasive species can out compete native species for resources and space drastically lower the biodiversity of the ecosystem. Humans are the #1 way invasive species spread by ‘hitchhiking’ onto watercraft, clothing, vehicles and even your pet! Simple actions listed below are a free and easy way to protect the native plants and animals found in your backyard.

1. Clean, Drain, Dry

  • Clean all plants, animals, or mud from watercraft & related equipment
  • Drain any water onto land
  • Dry all items completely

Press release 13

2. Be PlantWise

  • Choose non-invasive plants for your garden
  • Remove invasives from your garden
  • Avoid wildflower seed mixes

3. Dispose of garden waste properly

  • Do not dump garden waste in public parks, natural areas, and roadsides
  • All landfills within the CSRD accept invasive plant species for deep burial (fees). Ensure your material is bagged in clear plastic bags and notify the attendant that you have invasive plant species
  • NEVER compost invasive species
  • NEVER put invasive species into CSRD Yard Waste (Deep Burial at landfill instead)

4. Clean off ALL your recreation equipment….Play Clean Go

  • Remove mud & plant parts from gear, boots, pets & vehicles
  • Arrive at the trailhead and recreation site clean
  • Stay on trails



5. Report- A-Weed

  • Know and report the high priority species in your region

Photo credit: CSISS. Invasive Leafy Spurge is one of the top priority species in the Columbia Shuswap region.

Latin name:

Tribulus terrestris  

Native to:

Europe and Asia 

Regional Distribution:

Puncturevine grows exclusively in southern BC, Osoyoos and Oliver, but has the potential to spread.  Puncturevine is currently on CSISS’ regional EDRR watch list.


Puncturevine forms dense mats along roadsides, vacant lots, beaches and unpaved parking sites. Each plant can reach up to 3 metres in length and has hairy leaves and tiny yellow flowers. A few weeks after the yellow flowers bloom, spiny, sharp seedpods emerge. These sharp seedpods have a mild toxin at the tip and can easily cut skin and make humans and animals ill. The seeds spread easily by attaching to animals, humans and even tires.


Mechanical removal (digging, hand pulling, tilling) is effective against infestations when completed before flowering and seed production. Herbicides such as picloram, dicamba and glyphosate have been successful.

For information on prevention and control methods please refer to Weeds BC page 128


Latin name:

Euphorbia cyparissias  

Native to:

Europe and Asia 

Regional Distribution:

The distribution of Cypress Spurge is a major concern in the Kootenay, Okanagan, Thompson and Cariboo regions of BC.  In the Columbia Shuswap, it can be found in the Salmon Arm IPMA and Golden IPMA.  Cypress spurge is a provincially noxious weed under the BC Weed Control Act.


Similarly to Leafy Spurge, Cypress Spurge is a perennial found at low to mid-elevations on dry roadsides, grasslands and open forests rapidly forming large colonies. It has clusters of bright yellow-green flowers that bloom earlier than those of the Leafy Spurge. The leaves have no leaf stalk and are hairless, narrow and spiral around the stem. The leaves of the Cypress Spurge tend to be narrower than those of the Leafy Spurge. The extensive root system can exceed 4.5 meters horizontally and 9 meters vertically making it an aggressive invader. Cypress Spurge is categorized as a competitive invasive plant as it produces a compound in the soil that inhibits the growth of other plants nearby.


Herbicides have been successful with small infestations. Multiple treatments are required every year for several years due to the aggressive nature of this plant and can re-infest rapidly if left untreated. Mechanical removal is ineffective due to the extensive root system of Cypress Spurge.

You can help!

Be Plant Wise! Plant native or non-invasive alternatives such as Broad-leaf Stonecrop, Yellow Ice Plant, Red Hot Poker, Common Rockrose and Yellow Gem Shrubby Cinquefoil.

Latin name:

Chondrilla juncea  

Native to:

 Southern Europe, Asia and Africa 

Regional Distribution:

Rush Skeletonweed is a provincially noxious weed and is a major concern in the Kootenay and Okanagan regions. It poses a serious threat to rangelands, gravel pits, drylands and land irrigated for cereal production. In the Columbia Shuswap, rush skeleton weed can be found in the Falkland area.


Rush Skeletonweed is an aggressive invasive plant that spreads rapidly through plant fragments, its extensive root system and parachute-like seeds which can be transported up to 20 miles. It produces small yellow flowers and can be identified by stiff reddish-brown hairs that cover the base of the stem. This plant has wiry, thin stems, which ooze a milky sap that contaminate and damage cultivation machinery. It also drastically reduces crops yields by out-competing forage crops for soil moisture and nitrogen.


Herbicides have been successful when multiple treatments are applied annually.  Mechanical removal is effective on small infestations but repeated weed pulls are required due to the extensive root system of Rush Skeletonweed.

For information on prevention and control methods please refer to Weeds BC page 140


Latin name:

Butomus umbellatus  

Native to:

Northern Africa, Asia and Europe 

Regional Distribution:

Flowering rush has not yet been found in the Columbia Shuswap region but is an invasive species to watch for as it is currently found in isolated locations around the province of BC. It has had a major ecological impact on the natural ecosystems of the Great Lakes and is causing concern in BC.


Flowering rush is an aquatic perennial commonly found along shorelines of lakes and rivers, in canals and ditches. This almond-scented plant produces an umbrella shaped array of small pink flowers. The stem can grow up the 3 feet in height and forms dense stands along the shoreline.  Before the flowering stage of this plant it can easily be mistaken for Seacoast bulrush and bur-reed.


Mechanical control such as careful digging is an effective method in areas where flowering rush is present in low density. The entire plant must be removed in order to ensure complete eradication of the species. Buds or other root fragments can quickly and easily develop on soil.

For lakes without Flowering Rush, prevention is the best control. Clean, Drain and Dry your boat before launching into another water-body.



Latin name:

Cirsium palustre  

Native to:


Regional Distribution:

Marsh plume thistle currently has limited distribution in the Columbia Shuswap Regional District. This species is  being controlled and monitored in both the Revelstoke and the Salmon Arm Invasive Plant Management Areas (IPMA’s).


Marsh plume thistle is distinguishable by clusters of purple flowers located at the end of its stems. The stems are usually single, un-branched with hairy leaves, growing up to 2 meters tall. It is commonly found in moist woodlands, riparian areas and roadsides.


Mechanical removal is an effective method of control when done before flowering to prevent seed-set. If the area is hand-pulled or cut/ mowed before flowering, the plant can be left to decompose on site. If plants have started to flower, flowers must be bagged and removed from the site to prevent the production of viable seeds.  More information about Marsh Plume Thistle and control options can be found on the TIPS sheet.
