The tea bag test!

This summer, the Association took part in a worldwide initiative by researchers in ecology at the Deakin University, in Australia, following a suggestion from our allies Sauvons L’Anse-à-l’Orme. It was an exciting adventure!

The project is called the TeaComposition H2O – Global Aquatic Litter Decomposition Initiative. The research consists into measuring the impact of climate, floods and other factors on the decomposition of the aquatic litter, therefore, on the carbon cycles and the greenhouse gas emitted by this environment. This is advanced scientific research aimed at better understanding the complex dynamics of climate change.

The soil samples are collected using tea bags! Indeed, the tea – which we dried in advance – will absorb the liquid in the ground. We will then collect the bags after 3, 6, 12, 24 and 36 months to send them to the Deakin University for analysis.

So, two teams of APEVIB volunteers, composed of Emily Brown (biologist), Michela Artizzu (trained in inventory and research in biology), David Kalant (biochemist) and Marie-Chantal Scholl (coordinator for the APEVIB) went this summer in the Parc-nature du Bois-de-L’Île-Bizard and the Parc-nature du Cap-Saint-Jacques à L’Île-Bizard to plant tea bags in the wetlands, with both feet and hands in the mud!

We are very excited to be part of this worldwide project, which reminds us that this beautiful island is part of the planet’s ecosystems!

So, if you come across the orange flags, think about us, the tea bags and our neighbors in Australia!

 

A million thanks to our volunteers and many many thanks to Ira Tanya Handa, teacher at the biology department of UQAM, for lending us her lab!

LOOKING FOR BIOLOGISTS AND/OR CHEMISTS

The APEVIB (Association pour la protection des espaces verts de l’Île-Bizard) is currently looking for biologists and/or chemists to take part in the TeaComposition H2O Initiative, a worldwide study led by researchers from the Deakin University, in Australia. The study aims at studying the long-term litter decomposition and hence the long-term C dynamics, and its key drivers both in terrestrial-based and marine ecosystems. Additionnally, the project offers the possibility to test soil samples. These are key indicators of climate change and pollution in the mid- and long-term.

This is a unique opportunity to take part in a worldwide fight against climate change!
 
In short, the process consists in inserting tea bags in the soil and letting them incubate for 6 months to 3 years. The samples are then sent to the Blue Carbon Lab in Australia for analysis.
 
The APEVIB is looking to form one or two teams made of two or three people in order to proceed to the installation and retrieval of the tea bags in Ile-Bizard’s wetlands, as well as various data gathering (temperature, water levels, sample weight, GPS coordinates, etc.).
 
This will necessitate about 10 hours (spread over two days) of your time this summer, that is for a meeting, a few emails and a day for preparation/installation. Same thing for the retrieval of the bags, so about 10 hours next Spring, with the same people or different. More details will be given to participants.
 
If you are chemist or biologist, or you know people with such skills and knowledge, please, write us an email at espacesverts.ilebizard@gmail.com.
 
Thank you in advance for your help!
