Re: What Did This?

okay well it does look like no one is going to chime in so i am going to say cedar-apple rust? Kt are they going to have another tree preservation clinic? how do you get hooked up with the kind of work you do, thanks for the sites i am going to check them out... i love learning i think it is just the best thing there is. anyway my guess is in.
 
Re: What Did This?

You bet, Starlet, cedar-apple rust it is.
The telial galls on the red cedar were just about perfect when I took the picture. The aecia and pycnia on the apple leaves were also just exactly ripe.

Learning is the fun part!

Ha, ha, I don't know if I'd recommend my path to anyone else, but it has worked out for me. Lots of formal schooling and apprenticeships both formal and informal.

In January, am at the Northern Green Expo in Minneapolis and a root/soil workshop outside of Philadelphia. I don't organize or arrange anything, I just go where folks invite me and when I have the time in my schedule. Was at the NE chapter of ISA conference in October and will be at the Western chapter conference in May. Probably not much help, but I'm out there a lot!
 
Re: What Did This?

Okey dokey Starlet.

This one is just cool to see even if its not a real headscratcher for the sharply honed analytical talent on this forum.
I've seen this several times here. I think it could be seen across most of the regions people on this forum work in.

Re: What Did This?

The galls when dry look like brains to me, so the teleomorphs look like a brainstorm.

I've seldom seen the coniferous host suffer from this. The galls are imo quite ornamental when reproduction kicks in, as with other organisms...So Kevin does that mean that, since the appearance of fruiting fungi are the "crop" in my yard, then controlling this non-pathogen (in my yard) would be contraindicated?

Or does that depend on the proximity and value of the alternate host? In VA, the conifer is cut out with the force of the law within 5 miles of the orchards.
 
Re: What Did This?

That's what I mean. In Virginia, the apple is the economic crop and the red cedar (really a juniper) is considered almost a weed tree.
In Kentucky, Missouri, etc., red cedar is the economic crop and folks go out and try to remove wild or naturalized apples. Like I say, it depends on what is considered the crop species.

I don't really know how successful any of these control measures are. A good description is in:

Re: What Did This?

Wow Frax good one... either my eyes are going bad or i can not tell if that is tunneling by beetles or scratching by something??? i got to blow it up some. i will keep looking at it though, any way Kt i read some of your articles not to derail this thread you are good!!!!
 
Re: What Did This?

okay it is winter and usually animals will eat the bark of this tree, however it is usually much lower, they are not tunnels, look like scratch marks or teeth marks so with this said, a critter damaged tree....deer/moose?
 
Re: What Did This?

Maybe the image is not that great. But it is what it looks like - hint - chisel marks. Definitely caused by a critter Starlet but not a deer or moose.
Maybe there is some regional bias here but I just checked the zone map for this critter and it should cover all of Canada and most of the US except the southeast states.
Here's another image attached.

Re: What Did This?

Hey Starlet. Cervi's good eh, considering they don't even have this critter (the real critter in question)in Florida! (He had a little help from a right-handed mouse).

I'm not even gonna touch that climbing beaver one! Was about to and saw quickly where this thread could go!

Re: What Did This?

I wondered if it might be porcupine, and then the header on the photo gave it away. I remembered reading a story in first or second grade where a porcupine was captured in a wood box, and chewed its way out of it.

I don't have any photos to post, so please, someone else step up and post a photo. I love this thread!
 
Re: What Did This?

Here's one from upstate New York on sugar maple. Crown symptoms include thinning of foliage and branch dieback. Can kill mature trees in just a few years.

Re: What Did This?

okay i am going to give some one a chance i know this one. to comment to frax, your picture was fine my eyesight is not what it used to be, anyway i have never seen this type of damage , i dont think we have that beaver here or if we do, he keeps a low profile..... good one. KT this is an excellent picture.. if i am right this could become or already has become quite the problem
 
Re: What Did This?

Hmm, it seems to have entered between buttresses, where bark is included, and raced to the heart--very fast indeed! Beautiful pattern of discoloration, no visible fruiting bodies. Hmm...
