Updated Uncommon Trees on UMBC (Herbert Run)

We have approximately 100 trees left to identify in the Herbert Run section on the UMBC campus. As we are getting close to the end of the identification process, I sifted through the data again to give an updated list of the uncommon trees within this section. To be considered uncommon, the variety of tree had to appear no more than 10 times throughout the entire section. The…

Maple tree species differentiation

Much like the different varieties of Oak (Quercus) trees, certain maples (Acer) are known to create hybrids and become difficult to differentiate. An easy example of this is the Black Maple (Acer nigrum) which can be confused with the Sugar Maple (Acer saccharum). Some people even consider the Black Maple as a subspecies of the Sugar Maple,…

Oak Varieties on UMBC

We are making a lot of progress with the tree identification process on the UMBC campus. There are about 17 plots left to go through for the Knoll before I begin inputting the missing tree ID's for Herbert Run. On top of that, there are a handful of trees that need to be verified. One genus in particular, the Quercus (Oak), can be difficult to differentiate due…

Uncommon Trees on UMBC

Although tree identification is still in progress, I noticed that there were a few very uncommon varieties in the Herbert Run section at UMBC. Out of the hundreds of tagged trees in Herbert Run, the Water Locust (Gleditsia aquatica), Eastern Redbud (Cercis canadensis), and Red Mulberry (Morus rubra) were each only identified twice. Along with being…

Ecosynth Goes to Harvard Forest

Ecosynth recently had the chance to get a fly over of a small part of the famous Harvard Forest in Petersham, MA.  

For over 100 years, the forest here has been the site of countless research projects and on Wednesday of this week, and today, I flew our v5.0 Hexacopter over a few small patches of forest, pasture and work buildings to generate 3D…

Data Sheets

I'm sifting through the last thirty or so data sheets for the Herbert Run trees on the UMBC campus. It stood out that there were many repeated genus/species identifications for the largest trees in this section. The most…
