On with the workplan

The garlic mustard is now more in control at Riverdale (at least for this year) so we can work on other invasives.

We came back after a week off to a ton of stinging nettle. It's pretty much everywhere.

The stewards are being very careful at protecting themselves and they were practically shovelling it out of the way.

The park is closed in the evening so we don't see people walking by but the creatures seem curious about what we're doing. Too bad we can't give them our brochures about the program.

We also started removing burdock which we have managed to keep in control over the past few years. I found several web sites discussing this plant and even though some of them praise the medicinal values of it, most agree that it can be highly invasive and even dangerous. The burs that it produces can damage the fur of animals brushing against it and they can also kill birds. This Ontario Wildflowers website has an interesting article about it.

The stems remind me of rhubarb.

Dog Strangling Vine (DSV) is also very friendly with burdock. We started removing some of the DSV, although it's still a bit early for that.

On one of the slopes at Riverdale, we also saw another invasive called Dame's rocket . According to Wikipedia, it is a herbaceous plant species in the mustard family and is cultivated in many areas of the world for it's attractive spring blooming flowers. However, as pretty as it is, it's a non native invasive. Luckily, we don't seem to have as many of it at Riverdale compared to other areas of the Don.

I'll never think of burdock the same way again. Killing birds! I'll be sure to keep it under control in my neck of the woods.
