Where I live now, the area is very flat. But one thing about flat land, there is an abundance of wetlands. And wetlands in spring are just beautiful.
What you are seeing in the first three images is the ponds filled with invasive waterlilies. As beautiful as they are, they are very bad for the water life habitat.
The park below also battles invasive plants. I have pulled Mustard Weed at a local nature preserve, but cannot image tackling the Bird’s Nest Trefoil shown below.
Can you imagine what a chore that would be? Again, very pretty in the fenced wildlife area, but not native.
Next time in your local nature preserves, check out the invasive plants. It might astound you as to the number of them. In this changing, warming and drying climate, more and more plants are on the move and will show up places they were not found previously. Soon what was not native will be what will be.
