Next event, Saturday August 17th!

Pond Preservation in a Changing Climate
Both this summer and last, Edgartown Great Pond has exceeded 85 degrees Fahrenheit, the upper limit of temperature range for healthy ponds. Excess heat puts stress on the delicate balance of the Pond’s ecosystem. Most native animals and plants are adapted to cooler temperatures. Their biological cycles can be impacted with by extreme temperatures. Algal blooms are more common when temperatures are hot. With warming temperatures predicted, we need to adapt our management strategies to reduce the stress factors we can control, such as nutrient inputs into our coastal ponds and estuaries.
The last decade of restoration on Edgartown Great Pond has resulted in clear water and a thriving ecosystem. Maintaining and protecting these resources is critical to the future health of the Pond and the planet.
Understanding Algal Blooms

Now more than ever, it is important to learn about algal blooms. Blooms are becoming more frequent both locally and globally, with increasing temperatures and excess nutrients feeding the excess growth, or blooming, of algae. Do you know the difference between micro and macro algae? What types of blooms are harmful to humans? What is the environmental impact of algal blooms? Learn about all this and more from Marine Biological Laboratory scientist, Dr. Kristin Gribble on Saturday August 17th at 10 am at the Edgartown Library. Following the presentation on algal blooms, there will be a panel discussion with local biologists and civic leaders about the importance of preserving local waters and the challenges facing our coastal ponds.
