Because of the warm winter on Cape Cod this winter, the alewives are returning early to the local rivers. Alewives are a type of herring. They’re anadromous, meaning that they live in the ocean, but swim up freshwater streams to spawn.
Their population is declining in New England, so the River Herring Network organizes herring wardens and volunteers (called “monitors”) to assess their numbers during the spring run. The counts go on for two months, with volunteers assigned specific times each week to count.
Locally, the count is connected with efforts by the Friends of Herring River to restore that river to something akin to its condition before the Chequessett Neck Road Dike was installed and the surrounding wetlands were developed.
Susan got the official training for the count, so she’s the real Monitor, but I went along as a volunteer for the volunteer. I guess you could say that I was an Unofficial Herring River Estuary Alewife Monitor Assistant (UHREAMA).
We decided to cycle to the site for our first scheduled count. It’s only a half hour away, but has some good hills and soft sand paths to make the cycling interesting. We passed Black Pond and a friend’s house on the way. You can these and other photos at photos from the count.
The official count site is at a beautiful bend in the tiny Herring River, with a fallen willow marking the spot and serving as a convenient shelf for the field test kit. Byu the way, there are many Herring Rivers. This is the one in Wellfleet.
Here’s the data for our first foray:
- Time: 9:07- 9:17 am
- Air temperature 12 ºC
- Water temperature: 13 ºC
Unfortunately, the number that matters most is this one:
- Number of herring: 0
Somewhere else, this bridge over the Herring River would be seen as in need of a little repair, but here, it’s just a reminder of the alliance between culture and nature in the National Seashore area. That alliance isn’t without its problems, as we can see in the decline of the Herring River and its herring, but at least there’s an effort to try to make it work.
