The highlight of my week was heading out to Anderson Lake in D’Arcy to treat Yellow Flag Iris. We patrolled around the shorelines near the main docks via kayak and came across a few patches. These patches had extensive root systems that were growing in a mat-like manner, weaving through thick grasses and tree roots that lined the creek mouth. This made treatment quite difficult and messy; using a pick axe, we manually removed the patches. To remove Yellow Flag Iris properly, no root fragments can be left behind as even small remains can re-generate into a new plant. Due to this tendency, we had to basically remove chunks of land about half a meter in depth. Although removal was tough, it is extremely rewarding to pull out large root systems that are till intact.
We also had the opportunity to head up the Birkenhead Forest Service Road to treat Scotch Broom. To do so, we had to use radios to call and ensure the roads were safe. This is something I had never done before and is a good habit to practice when heading into active loading areas. The Scotch Broom we went to treat was a single plant just off to the side of the road whose sighting was reported by a citizen and then confirmed through images. It is somewhat concerning to see Scotch Broom that far up an FSR, especially 50km+ north of our containment line. However, it is very likely that a single seed was attached and deployed from a vehicle’s wheel well; the plant had not yet gone to flower so it is unlikely to spread any further.
In closing, having passed my Pesticide Applicators exam, I had my final pesticide training this week and will likely be spraying and treating sites this coming week!
