Naturalist Ed Series: Fish of Osborn Preserve

Join us to learn about Osborn Naturalists’ recent fish observations in Osborn Preserve’s Copeland Creek! We will explore a beautiful section of the perennial creek while we learn about new SSU research involving a special-status fish species that typically uses both fresh and saltwater to complete its lifecycle.


Kaylie Richards, Osborn Educational Assistant and SSU student, has been studying the recently-observed fish in Osborn Preserve’s Copeland Creek. 


Over 70 percent of the planet is covered in water which explains why fish are so diverse. Fish live in a variety of habitats in rivers, streams, lake, ponds and open ocean. Explore Osborn Preserve’s Copeland Creek to learn about the fish species which has recently been observed here by Osborn Naturalists. Along the way, we’ll learn about new SSU research involving these fish and how they might be affected by climate, habitat loss and environmental degradation, and what we can do to support the conservation of these amazing animals.
