Our Bald-Cypress Swamp is definitely a location on grounds that is a visitor favorite. This vernal pool is man made and was introduced to the property in approximately 1929. The water level of the pool today is maintained by The Arboretum using a hose attached to the water system. We are committed to keeping this a functioning vernal pool due to the large population of amphibians that use it as an early spring breeding pool.
Depending on the season you are visiting, you may find yourself encountering salamanders and frogs that have traveled over from the Woodland Garden areas. So, what can you see around this time of year? Below are some images from our Senior Field Biologist, Doug Berube.
This photo above shows the relationship between spotted salamanders and green algae. The algae has grown over the salamander egg mass and the algae then enters the developing eggs. This allows the algae to also enter the egg’s tissues and cells to then perform the relationship called endosymbiosis. Research suggests that the algae is photosynthesizing the egg to then provide oxygen that will assist the developing embryo.
The spotted salamander egg mass pictured is partially above the water surface. This has led to a portion of the eggs freezing and dying. However, those that remained below the water surface are thriving as normal. Those embryos are developing into the salamander larvae with gills to then survive underwater. This process is leading to their metamorphosis state to juvenilize.
Here you can see that the wood frog tadpoles have also emerged and can be seen swimming around the area. Soon, they will sprout legs to become a froglet and then eventually a frog!
