These beautiful cherry trees were in full bloom today outside the Shippensburg Borough Police Department. At first I thought they were the result of years of intense pruning. It turns out that these Weeping Higan Cherry (Prunus subhirtella) trees are the result of numerous branches grafted to a single stem. They certainly add a dramatic element to the landscape.

The overview of his presentation is that of the 58% of Pennsylvania that is forested, much of the land is privately owned and the size of the land is being parcelized (broken into smaller and smaller tracts). Since most land owners who harvest their forests do not hire a forester, the result is high grading and not thinking about the future forests. They are not waiting for adequate regeneration and what does manage to regenerate is not what we want to see. The main tree species that are regenerating are red maple and black birch. Deer don't eat them or fern. The fern shades out and filters the light needed by the tree seedlings and then if oak regeneration does manage to out grow the fern, the deer browse it off. If the deer don't browse it off, then the oak has to compete with the faster growing birch and maple.
Using tests such as the ASID test and fencing out deer, we can see that the deer, fern, and competition as well as invasive insects like the Gypsy moth paint a very bleak picture for the oak. One of the things that we can do is educate the public and try to use best management practices to ensure a strong forest in the future.

Here is a map I made of Mount Washington in New Hampshire:

Mount Washington is the highest point on the east coast of the USA.
I am not sure how they select the contour interval. It seems to be 40 feet.
Here is another map of the Waynesboro Reservoir:

This one also seems to have a 40 foot interval, too. It will be interesting to check other regions, such as the Rockies. I do like the effect of contours and shading to show elevation. This is a great option. It turns the online maps into much more of a professional tool.
