I went back and took more photos and observations of the felled tree by the trailhead. I observed that there are apparent exit holes on the top side (the cut edge) of the stump. I searched the felled part of the tree and did not observe any holes on the cut edge of that tree. The stump appears to continue to otherwise be in good condition and have living cambium.
It appears that the exit holes occurred AFTER the tree was felled.
I have not contacted the park yet, as I still want to know more about their own ALB surveying and why they cut down and left several trees on the trail.
(I suspect that the beetle contamination to the living stump could have been caused by poorly cleaned felling equipment, used from another contaminated site.)
This trail shows a good number of living and Felled trees with Bug Damage. I did get to take pictures of and record several separate tree sites. Several trees were already felled and had prevalent small exit holes (possibly EAB) they had been marked with orange and blue hashes. The living trees showed a variety of hole sizes and shapes. A rather artistic bore track was noticed a a couple trees where the borer had made several whirling tracks and the bark had fallen off. I will post the pictures for I.D. A felled tree near the Trail head had some very round, pencil sized exit holes where the bark had been removed.
Did a Brief ALB Survey at this Nature Preserve. I observed bug damaged to downed trees immediately At the turnaround point in the mapping trail I observed a bug damaged live tree, over 60 feet tall, deciduous hardwood. I took multiple sample of bug parts and casings for analyzing later. The photos I took of the damage and the whole tree did not save. I planned to ID the tree from the photos. I will return to this preserve in the near future as there does appear to be evidence of unidentified beetles.
Quite a contrast with the Cleveland Metro Park survey this week. More trees were in much better health with much less indication of bug damage. The overwhelming observed trees with damage were dead and downed trees. Again no obvious ALB like indicators. The areas around the ledges change from stands of confers to deciduous hardwood several times on this trail.
I surveyed an area along the Multi-purpose trail of the Mill Stream Run area of the Cleveland Metro Parks. Below is a "Map My Hike" GPS graphic of the area I observed. There was a noticeable amount of bug damage to trees in the area. According to a staff member of Camp Cheerful along this path the park had already cut down several trees in that area due to bug damage. I could not identify the type of bug but I do not believe it was ALB as the holes were not large enough or round enough to be ALB. It was also difficult because the damage was older and was pecked over by woodpeckers. . I took a half dozen photos but am still having difficulty saving and posting photos off my Droid. This will be an area that I will revisit in the spring to try to observe the insect and identify it. I will also try to contact the Metro Park to get it's reports of beetle infestations.
Well, I have decided the the MapMyHke app is good for recording the route that I survey but I can not manage to upload the photos and their locations. I will be trying out a new app Sunday that is supposed to relatively accurately post my photos on a map along with there GPS location on the route that was surveyed.
I used the MapMyHike app and then took pics using the camera function on the app. I was hoping the photos would be marked on the map where they were taken but that did not seem to happen I am still looking for a way to post photos on the maps of where I have surveyed. .
OK, so I figured out what buttons to click on to find the HTML to post the app results on this Blog, Check it out, it's pretty cool. I posted all three sizes just to see how they appeared on the site. It looks like the medium size will be the most effective.
Well is seems all I can manage to post so far on this Blog site is the Google Map view. I hiked the Salt Run Trail of the CVNP to test out The Map My Hike app. This app Map is pretty awesome, showing elevation, location labels and 3d flyby views. I am able to post that link on my HXF Facebook page https://www.facebook.com/Longhornedbeetle. It also has the capacity to take photos with my cell phone and post them on the trail map, a feature I really want for recording the location of any evidence of tree damage. Check out the FB page and see if you can access all the features it offers.
If you have any more info on how I can like the Map My Hike app directly to this Blog please let me know.
