UMass CBL at Bussey Brooks

The Canopy Biomass LiDAR (CBL) is an ultra-portable terrestrial scanner developed by Rochester Institute of Technology and refined by University of Massachusetts, Boston.

On the 4th November, 2013, the CBL was deployed at Bussey Brooks Meadow, MA. The aim was to provide some mid- and under-story structural information to compliment a concurrent UAV fly-over.

The understory was fairly dense, and the wind was fairly high, which produces some occlusion artifacts in the…

Uncommon Trees on UMBC (updated)

With the end of the semester about one week away, I thought I'd revisit the data and compile a list of the uncommon tree species on the entire campus, as promised. This is still not a completely finished list as there are some unidentified trees and some that are only identified by genus. Due to the…

UMBC Crown Mapping

Over the course of this project, we have done numerous flights to map our two forests on the UMBC campus. The recent LIDAR scan also added another layer of detail to our aerial images. Needless to say, we have a very good idea of how each forest looks from above. However, we were interested to see if we…

USGS Tree Species Distribution Maps

The tree identification process on the UMBC campus is coming to an end. We have approximately 45 trees that need to be identified before we add the finishing touches on our data collection. With the amount of diverse species present on campus, it helps to know their general distribution in our area. I was…

The start of a possible species invasion?

After another week of sifting through the spreadsheets for the trees on UMBC, I noticed yet another pattern. The Ailanthus tree species (Ailanthus altissima), also known as the Tree of Heaven, was identified a number of times on campus. However, it was only identified in the…

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…

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…

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…
