How many tree pics can we enter?

I have these other cool pics I'd like to share.....
This is taken in Rancho San Antonio Open Space.....
I volunteer with my son, at a small educational "turn of the century" homestead that's in the middle of the Open Space...
When our chores are done, we hike in the hills.... This week I found this oak tree that had it's own natural guild of natives underneath......

I've used up my 3 pics, but there was also salvia apiana [sage] there, and some other "stuff" - really cool!

Nice pics ! Tell me more about this homestead you and your son voluteer at!

It's in the hills around the South Bay - Silicon Valley California.....
Unless you have volunteer privileges, you have to hike in and back...about 3miles round trip....
When you arrive we have a cow with calf, 5 sheep - various heritage breeds -some with lambs, 2 meat goats dur to birth in April, 1 milk goat, 2 pigs...They're getting old and arthritic, so we're borrowing piglets this year, and hand them back when they're ready for market.... We have a demonstration garden , chickens that roam the farm, ducks and geese....Some rabbits and a couple of barn cats that have gotten so fat of late we're sure the public is sneaking them snacks!
We have an old blacksmith shop, old settlers cottage furnished turn of C...You look in through windows...There's an old apple shed converted into a nature center........ A large pasture at the end of the farm has been "turned" into an Ohlone Indian Village.....wooden teepees / sweat lodge etc etc We hope to build a native herb garden in there this year.....The "old ways" are demo'd in the farm and village...Here is a link,

The Friends of Deer Hollow Farm - who help support it, also have a website with LOTS of cool pics.....

I love it there.....
Obviously there's a lot that does not want to be changed, as it's living history.....
We have set up a grey water system to water the trees in the cow pasture, and are considering how to grow some food for the animals - plant some mulberries / kale trees etc

Looks like a neat place Julie.

Thanks....Not permaculture exactly...But "nature".......
