Advanced technology For tree removalIn another case where advanced technology helped after trees had been drastically removed took place in Mexico. In this case illegal loggers have completely deforested a large portion of the most important site for monarch butterflies. The logging took place in the Monarch Butterfly Biosphere Reserve, where 10 hectares (approximately 25 acres) of vitally important trees have been cut down over the past year. A year ago is when news of the deforestation came to Brower and his fellow researchers from local environmental activists. Citing potential safety concerns, unfortunately the reserve, however, did not allow researchers onto the site to examine the problem.

All thanks to technology advancements they used a drone over the site revealing the scope of the logging. The drone was operated by a local filmmThe weather, pests, and even people are some of the enemies which the trees that grow in our cities endure attack from. Without getting the proper permissions some homeowners even go chopping down these trees. Putting a spin on the old forest adage, the D.C. Urban Forestry Administration uses advanced technology to uncover illegal tree removal.

To better manage urban trees and ensure that they thrive and survive, these constant assaults require that foresters and arborists, society’s civic tree stewards, take a detailed inventory and analysis of trees.

The Urban Forestry Administration (UFA) at the District Department of Transportation (DDOT) in Washington, DC, by using GIS to improve its inventorying and spatial analysis methods is protecting its urban forests and enforces tree-removal penalties more accurately. The organization makes use of Esri software like ArcGIS Online, Collector for ArcGIS, and ArcGIS Pro in this struggle, all thanks to the advance technology which is making this possible.


UFA used a typical personal digital assistant (PDA)-based field collection way to collect data about trees in Washington, DC from 2006 to 2013. Using handheld PDA devices a team of 18 arborists inventoried the district’s trees. Information from those units had to be uploaded and manually merged into the street tree database, back at the office.

With technology advancements in 2014 using the Esri ArcGIS platform UFA started to monitor the condition of DC’s urban forest in real time. Using the Collector for ArcGIS mobile app connected to ArcGIS Online the arborists in the field can gather information about trees (e.g., damaged limbs or signs of disease) on smartphones and tablets. In real time the data that’s collected is then added to a map in ArcGIS Online.
This system helps arborists in monitoring street trees planted by the city and regulating the removal of privately owned trees. If freshly cut stumps in a neighborhood are noticed by arborists, they can see whether the proper permits were obtained to cut those trees using maps in ArcGIS Online. The true extent of Illegal Tree Removal in the city can be discovered in this way by UFA.

In order to issue fines that are fair and equitable to residents UFA also needs to know the location and dimensions of illegally removed trees so when someone cuts a tree illegally and the tree is not available for measuring UFA uses lasers and ArcGIS to discover the size of the removed tree.
aker whom the scientists turned to instead. The damage was also further confirmed by satellite images.

The tech, when they were created drones were never intended to tackle the illegal tree cutting activity happening in York PA, yet advanced technology helps uncover illegal tree removal in York PA using the above methods and more yet to be documented.
