๐Ÿธ๐ŸŒ™ What a wild day (and night!) in the Hollow!
Yesterday was packed with incredible wildlife encounters at Hawthorn Hollow! During the final day of Nature Camp, our campers headed to Pollywog Pond, where they caught some GIANT bullfrogs. ๐Ÿธ

Then, as the sun went down, Frogs After Dark brought even more excitement! Hikers explored the Hollow after hours and spotted all kinds of nighttime creatures, including flying squirrels, salamanders, spiders, and, of course, frogs! ๐Ÿฟ๏ธ๐ŸฆŽ๐Ÿ•ท๏ธ๐Ÿธ

Thereโ€™s something extra magical about experiencing the Hollow after dark. Thanks to everyone who joined us for an evening of exploring, discovering, and getting a closer look at the amazing creatures that call Hawthorn Hollow home! ๐ŸŒฟ๐Ÿ”ฆโœจ

๐Ÿ„ Back to Nature with Nicole: Mushroom Edition! ๐ŸŒฟ

Thereโ€™s a lot popping up at Hawthorn Hollow! In our latest Back to Nature with Nicole, Nicole introduces us to three fantastic fungi you might spot around the sanctuary:

๐Ÿ„ Chicken of the Woods โ€” Laetiporus sulphureus
๐Ÿ„ Dryadโ€™s Saddle (Pheasant Back) โ€” Cerioporus squamosus
๐Ÿ„ Giant Puffball โ€” Calvatia gigantea

These mushrooms are fun to find, fascinating to learn about, and, most importantly, an important part of our woodland ecosystem.

When exploring Hawthorn Hollow, remember our simple rule: Look, Learn & Let Nature Grow. ๐Ÿ‘€๐ŸŒฑ

๐Ÿ“ธ Snap a photo, but leave mushrooms where theyโ€™re growing.
๐Ÿฅพ Stay on designated trails to protect emerging mushrooms and the delicate habitat around them.
๐Ÿ„ Please remember that foraging and harvesting are not permitted within the sanctuary.

See what Nicole discovers, then head out on the trails and see what fungi you can spot for yourself!

Let nature grow wild. ๐Ÿ’š

๐Ÿ„ Look, Learn & Leave It Growing ๐Ÿ„
The first photo shows our Land Manager, Nicole, with an incredible Chicken of the Woods mushroom growing here at Hawthorn Hollow this past Friday. The second photo shows that same spot after the mushroom was foraged recently.

While we understand the excitement of finding an edible mushroom like Chicken of the Woods, foraging and harvesting are not permitted within the sanctuary. And thereโ€™s an important reason why.

Mushrooms are much more than something interesting growing along the trail. They are an important part of a healthy woodland ecosystem. Fungi help:
๐Ÿ‚ Break down fallen trees and organic matter, returning nutrients to the soil.
๐ŸŒณ Support trees and plants through underground fungal networks that help them access water and nutrients.
๐Ÿฟ๏ธ Provide food and habitat for insects, wildlife, and other organisms.
๐ŸŒฑ Keep the forest ecosystem cycling and thriving in ways we often canโ€™t see.
When mushrooms are removed, we also lose an opportunity for visitors, students, and future nature explorers to observe and learn from them in their natural environment.
Hawthorn Hollow is a sanctuary, a place where plants, fungi, wildlife, and natural processes are protected. When you discover something special here, we encourage you to take a photo, enjoy the find, and leave it for nature and the next visitor to experience.

๐Ÿ“ธ Take photos.
๐Ÿ‘€ Observe from the trail.
๐Ÿ„ Leave mushrooms where they grow.
Thank you for helping us protect the sanctuary and everything that calls it home. ๐Ÿ’š
