Transcript of Lower Mainland Green Teams -WE HAVE THE POWER!

Lower Mainland Green Teams
What are invasive plants?
Invasive plant species are non-native species that have been introduced from other countries or other regions in Canada that have a negative effect on the environment, the economy, and society
How are invasive plants introduced?

Invasive plants have been introduced through both intentional and unintentional pathways. These include:

Intentional introduction as an ornamental plant or agricultural crop
Intentional introduction for research purposes
Unintentional introduction as a contaminant in other plant products or livestock
Unintentional introduction through travel

Examples of Invasive Species in the Lower Mainland

History of Invasive Species
Question 1
Which of the following is an invasive species in BC?

Salmonberry Deer Fern Giant Hogweed

Japanese Water Iris Wild Celery
Question 2
What is one reason why invasive species are hard to control?
Question 3
Q1. According to the pie chart, what is the most noticeable result of an invasive species takeover?
Green Teams of Canada
Economic Implications of Invasive Species
Price tag
Globally, the world spends about $ 1,400,000,000,000 (5% of its economy) on invasive species every year
Canada's agricultural and forestry industries pay a hefty $7.8 billion of that
An 2009 analysis approximated that each invasive species in the study would cost BC between $1-20 million dollars without intervention. It also predicted that that cost spectrum will increase to $5-60million by 2020.

Perks of preventing!
The good news is that when action is taken against invasive species, the damage to ecosystems is greatly reduced.
Our Stories
I joined the Lower Mainland Green Team 6 years ago, when I was a high school student. I wanted to become more involved in my community and have the chance to leave the classroom and gain some hands-on experience. I stumbled upon this group online while I was looking for some potential volunteer opportunities and within a few minutes, I was already signed up for the next meetup! I didn't really know what to expect the first day, but I quickly learned that this group was the perfect way to give back to the community while having a LOT of fun!
I got involved via a school program---Lyda emailed my science teacher and asked if we were interested in helping out with some invasive species clearing in our local parks, and me and a bunch of other students were just like YEAH! So we got a lot of people together, suited up in long pants and shirts, and walked down o Jericho Park. We were a pretty intimidating group of twenty, and none of us had any clue how to dig English ivy out or even what English ivy looked like. But Lyda had such great energy and was just so welcoming and helpful---she lives by this motto that volunteers come first. I fell in love with both what the Green Teams is doing and how it's doing it.
In grade 11, my Science class took a field trip to a local creek with the LMGT. I came away with a strong realization that these seemingly tranquil spots are being silently ravaged by invaders. Since then, I have been hard a workhelping restore these places back to their original balanced and prosperous states, to be enjoyed by all, and have been working alongside the LMGT to bring that dream about.
Thank you for listening!
Invasive non-native species often cause irreperable damage to native ecosystems and agricultural lands and costs billions of dollars each year.

Effective use of biocontrol in South Africa has estimatedly saved $8 for every $1 spent against the red sesbania and $709 for every $1 spent against the jointed cactus.
Canada has 486 invasive plants

368 of them are present in BC, which has the third highest number of invasive plant species in Canada

Environmental and Socio-economic Consequences of Invasive Species
Threat to biodiversity - formation of a “monotype community”
Loss or physical alteration of habitat
Potential extinction of native plant and animal species
Soil erosion and alteration of soil chemistry
Impact on human health and recreation
Large economic cost for control and eradication

Why are Invasive Plants so Hard to Control?
Usually have very high reproduction rates
Have few natural predators and are not vulnerable to disease (these are two major factors that control the balance of native plant and animal populations)
Most have the ability to survive in diverse habitats, allowing them to thrive in the region they invade

Grows to 800 volunteers
Engages 1,340 volunteers!
Grows to 2,800 volunteers (Lower Mainland) and 1,200 volunteers (Victoria)
Present Day
Our Story
Who We Are
Non-profit organisation based in Lower Mainland & Victoria focused on environmental stewardship.
What We Do
Why We Do It
We believe that if we encouraged everyone to spend more time in nature, our society will become more environmentally conscious.
