This week we had to catch up to our schedule by completing blocks 1009, 1005, and 1022. In total we documented 16 trees with three of them being White Ash trees. Block 1005 was not included in our cataloging as this block had no sidewalk which we determined meant no public trees. Block 1009 was a small strip of land that acted as a lane divider for driving cars. The bulk of the trees we counted in this range of blocks came from block 1022.
As you can see from the above graph the most common tree is still the Ash tree however, both the Kwanzan Cherry tree and the White Ash tree are tied for most common species in this group of blocks. The Ash tree makes up about 24% of the total trees in this area reflecting what the previous blocks showed as well.
When combined with the previous data set we see that the White Ash tree dominates this list of top 10 most common tree species with 32.6%. Combined with the Green Ash tree species, Ash trees make up around 40% of the public trees documented so far. This highlights the issue that Ash trees which are incredibly vulnerable to pests and disease make up a sizable portion of trees in South Orange. This means that 40% of the trees we have cataloged are under serious threat of disease and pest. Hopefully this is something South Orange can rectify.
