A couple weeks ago I went to an amphibian egg monitoring training at the Water Resources Education Center in Vancouver, Washington. While I won’t be participating in the program, which is centered in Clark County, Washington, I thought it would be nice to learn some more about the amphibians of the Pacific Northwest.
We started the day with a couple slideshows and a look at some captive salamanders, before heading out to a local wetlands to look for egg masses in the wild. The Water Resources Education Center was one of my favorite places as a kid, but I hadn’t been back in years.
It’s an outdoor and informal education organization run by the City of Vancouver, right on the edge of the Columbia River and associated wetlands. The mission, as you might expect, is focused on water resources, particular the abundant wetland and river habitats of the Pacific Northwest. It’s a great place to learn about issues facing water resources in the region, as well as to see some of the native fish and amphibians you might not find in the wild.
Near the entrance is an area with a number of tanks and terraria, including salmon eggs and recently hatched alevins like the one above, as well as a bunch of native amphibians like this Pacific Tree Frog or Chorus Frog (Pseudacris regilla). We didn’t see any of these in the field, but we certainly heard them!
I find Western Toads (Anaxyrus boreas) and toads in general strangely charming:
Hanging above is a striking yet disturbing Salmon Lifecycle sculpture by local artists Maggie Rudy and Patty Maly, depicting the life cycle of the salmon in trash—such as that which ends up the oceans, negatively affecting salmon and other animals.
Moving towards the other exhibits, you pass a large fishtank, which usually has White Sturgeon (Acipenser transmontanus) and other fish. Later on, some of the salmon may move to that tank temporarily before release, although they can be aggressive. White sturgeons are the largest freshwater fish in North America, at their largest reaching up to 1,799 pounds (816 kilograms) and 20 feet (6.1 meters) and living over 100 years. In addition to overfishing, dams along the Columbia and Snake Rivers threaten sturgeon populations by reducing spawning habitat and blocking passage to and from the ocean.
I didn’t have time to poke around the main exhibit area, but I think it’s more focused on kid-friendly interactive activities and watershed education.
