Re: Maymont Park, Richmond VA

Bbeduhn, Interesting to know about the incense cedar in North Carolina. No other pictures of the dawn redwood. I realize its not the best shot but you can tell from the picture its a d.r. by the rusty-colored male pollen cones. Personally that is what any mature dawn redwood I have seen looks like, ...

Re: South Ms Black Creek Wilderness Trail

Nice tulips and big leaf. Being from more northern eastern coast I really recognized the difference between the prevalence and size of poplars when I lived in MS. NWR, Tombigbee, and to some extent Delta Nat. are the only places I have seen them exceed 20" dbh down there. When you live in the mounta...

Maymont Park, Richmond VA

Hello ents, Over the holidays while visiting family I walked around Maymont Park in Richmond Va. This 100-acre arboretum is one of the pride and joys of the city and is a must see for any tree enthusiast. It was built in 1893 by philanthropist James Dooley and his wife Sally, and after their death w...

Re: East Coast Albinos

Wow very cool, on the east coast I can only recall seeing variegation on broad leafs, usually because of a virus. Those shoots look like some legit albinos. This paper mentions, along with genetic factors, cooler temperatures and reduced light induced albinoism in oats and barley. I wonder if that i...

Tree galls

Hi all, A picture collection of different tree galls. Many of you are probably familiar with them. I find this symbiosis fascinating. The fact that the tree produces the gall for the successful reproduction of the organism demonstrates the remarkable evolution between plants, insects, fungi, and bac...

Re: Green River through Dinosaur National Monument

Thanks for recognizing the single-leaf ash, that is a new species to me. I know EAB has been confirmed in a Colorado county, probably from transported wood. Hopefully the remoteness and lack of host density will keep this species from being attacked.

Hi all, I had the chance to visit the green swamp preserve the other day in southeastern North Carolina. About 14,000 acres is managed by the Nature Conservancy. The area has been periodically burned and is a beautiful longleaf savanna with lots of regeneration. Multiple species of pitcher plants (S...

Re: The fungal relationships of trees

Don- Thanks, you always have something insightful to say in your comments. Clarks-nutcracker is a great example of symbiosis. I heard they were inoculating white bark pine with the slippery jack (Suillus sibiricus) in attempts to combat white pine blister rust. I hope it helps. Ray- That makes sense...

The fungal relationships of trees

Mycorrhizal fungi are extremely beneficial for trees, and in most instances are required for the tree to prosper. Mycorrhizae allow trees to absorb more water and nutrients, notably phosphorous from the soil. Additionally, mycorrhizae help defend trees against pathogens and nematodes, can suppress c...
