The sun is shining after several chilly, rainy days, and the weather has turned for the better. In the cool morning, deer and rabbits were seen at the edges of the garden. The koi pond is home to a variety of creatures, but until this afternoon I was unaware that there are now at least three turtles, and three or more Northern Brown water snakes. With a warming sun, all have come out to play.
In recent weeks I’ve plugged crevices between boulders that line the pond in hopes that the single snake would give up and possibly relocate to one of the neighboring wetlands. This was, of course, before others were seen this afternoon, and now I’m losing hope that I can discourage this growing family. The snakes are more a nuisance than a danger, though my wife disagrees.
In the short video, one of the smaller snakes moves across the pond, and then into the Pickerel weed, sweetflag, and yellow flag irises of the pond’s filtration area (below). The snake can be seen reacting to one of the large koi, but koi and the pond’s few large goldfish are not bothered at all by the snake’s presence.
The filtration area has become a dense thicket, and yellow flag iris (Iris pseudoacorus, below) is invasive if allowed to escape, so I carefully monitor the overflow of the pond. In the koi pond the iris seeds into every damp nook and cranny, so it must be chopped out on occasion so that it does not overwhelm vigorous, but less aggressive Japanese irises (Iris ensata). In the gravel filled filtration area, Pickerel weed threatens the invasive yellow flowered iris, and I would not be terribly disappointed to see it disappear one day.
