Today is World Ranger Day! A day where we shine a spotlight on the extraordinary impact park rangers have on our environment and well-being.

Rangers are on the front lines of conservation, helping to restore habitats, protect vulnerable species, and safeguard the natural systems that give us clean water, fresh air, and a thriving environment. Thank you for protecting the land we love for future generations.

Thank you, also, for your efforts to maintain our parks and facilities, provide fantastic community programs, and help visitors build meaningful connections with nature.

Your stewardship, passion, and dedication helps improve quality of life for so many and makes a healthier world possible.

Thank you! 🄾

Thank you Ranger Thomas for an interesting talk about the trails for our second Summer Talk.
He told us about other San Diego County Parks, as well as information about Dictionary Hill.
We learned how to keep our pets and ourselves safe on the trail, all while sitting under the trees, enjoying each other's company.

The Summer Talk on pollinators was interesting. We had fun making clay seed pods to plant seeds in the community.
These evenings are informative, entertaining and fun. Approximately 60 neighbors attended!
The next talk, with Ranger Thomas, will be about the proposed trails on the hill, how to stay safe and have fun when hiking. Date to be announced.
Mark your calendars for August 29th, when Charles Gailband will be back with his wonderful birds!!!
Thanks to all for making these talks so fun and so popular!

This was left behind after the Summer Talk last week. It is still on the fence waiting for you to pick it up!

What a wonderful presentation about Planting For Pollinators by Mackensie Karl this evening.
So many neighbors turned out to learn about planting native habitat in their yards. Both adults and children enjoyed the activity of making seed balls for planting native plants.
Thank you Cicely Suarez for all the great photos!

We are looking forward to the talk on back yard pollinators this afternoon. Hope you can make it!
