2016 Notices of Tree Removals

Campus and Community Planning works with landscape architects, architects, developers, UBC Building Operations and arborists to protect UBC's urban forest.

UBC takes pride in the diversity and amount of trees it has planted on campus since 1925. There are approximately 8,000 trees planted and over 10,000 native trees in natural settings. The University has professional arborists who manage this urban forest.

UBC encourages tree retention, or conservation through relocation on campus, whenever possible.  However, as part of the natural process of ageing and renewal, some trees decay and are at risk of falling. From time to time, under the guidance of UBC’s arborists, dying or decaying trees are removed before they become a safety hazard. 

Notice of Tree Removal - December 2016

UBC’s arborists have identified two Western Hemlocks (Tsuga heterolphyllum), located on the east side of Health Sciences Mall next to Patient Park, which have died. The trees died from being infected with a fungus. Arborists noticed these trees exhibiting a lean over the sidewalk, therefore removing it to prevent the risk of failure in the public area. 

The first tree was removed on Thursday, December 1; the second tree was removed on Friday, December 2.  There are no known replacement trees at this time. 

  

 

Notice of Tree Removal - October 2016 

UBC arborists have identified a Columnar Lawson’s Cypress (Chamaecyparis lawsoniana ‘Columnaris’), which is dead. The tree is located southwest of Cecil Green Park House. The tree likely died from root fungus. Arborists are recommending the tree be removed for safety reasons. Parts of the tree will be chipped and or reused around campus. The tree is scheduled for removal October 21.

 

As part of facilitating piping for a new district energy system that needs to be installed, one Lombardy Poplar (Populus nigra ‘Italica’) tree located south-east of the Wesbrook building needs to be removed.

The tree will be removed Saturday, May 21 and replaced by a different species in Fall 2016 that is more adaptable to the conditions. Some pedestrian areas may need to be cordoned off, however, every effort will be made to minimize disruption.

Notice of Tree Removal – May 2016

The University Boulevard area, including UBC’s diesel bus loop, is currently undergoing an exciting transformation. Over the next five years this key gateway to campus will combine academic and recreational facilities, shops, services, transit, housing and outdoor spaces.

This is part of UBC’s commitment to create an outstanding academic experience supported by a complete community where people can live, work, learn and play on the Vancouver Campus.

The next steps in this transformation process are:

  • Completing the new Aquatic Centre;
  • Demolishing the old aquatic centre to make way for the new MacInnis Field;
  • Building a new diesel Bus Loop;
  • Building the new Gage South Student Residence; and
  • Redesigning and starting construction on Wesbrook Mall.

To prepare these building sites, 73 trees surrounding the existing diesel Bus Loop will be removed starting on May 6, 2016, and continuing for a few weeks. These trees are a variety of species, including Pine, Cottonwood, Maple, Oak, Birch and Alder with an average diameter of 30 centimeters.

The trees will be replaced with an equal number, planted over the next three to four years as the area and landscape is completed. The trunks, branches and leaves being removed will be chipped for compost.

 

 

Notice of Tree Removal – May 2016

The Henry Angus Building, located on Main Mall and University Boulevard, is undergoing seismic upgrading.  During the upgrade, a new reinforced concrete wall will be added to the south end of Henry Angus Tower. This is one of several modifications to make the building more resistant to earthquakes.

As a result of the upgrade, an Austrian Pine tree (pinus nigra) will be removed because it is located where the reinforced concrete wall will be built. The removal is set for May 3, 2016. The trunk will be used for forest products and the leaves and chips for compost.

The pine tree will be replaced with three Crape Myrtle trees (Lagerstroemia) once the upgrade project is complete and conditions are optimal for planting. Two other Austrian Pine trees near the south entrance will not be removed.  

Notice of Tree Removal – April 2016

A Western Cedar Tree (Thuja plicata ‘Excelsa’) has been removed along the Main Mall near Stadium Road and the Rhododendron Wood.

The tree was located immediately above a section of sanitary pipe that needed to be removed.

Notice of Tree Removal – April 2016

UBC’s arborists have identified five Japanese Cherry Trees (Prunus Serrulata), located on South West Marine Drive near the Nitobe Memorial Gardens, which are in very poor heath. The trees were planted at a time when the surrounding forest was not as high as it is today, and allowed more sunlight to reach the five trees. As a result of decreased sunlight, the trees are suffering from the fungus Taphrina and are expected to continue declining. The arborists have recommended that these trees be removed before they become a threat to public safety.

The trees will be removed April 28, 2016 and replaced at a later date with a different species of tree more adaptable to the conditions.  Some pedestrian areas may need to be cordoned off, however, every effort will be made to minimize disruption.

Notice of Tree Removal – March 2016

Recently, UBC’s arborist identified two Western Hemlocks (tsuga heterphylla), located in the loading area of the UBC Hospital, that are dead. They recommended that these trees be removed because they pose a risk to the public and surrounding buildings.

Removal is scheduled March 2, 2016.  Some pedestrian areas may need to be cordoned off, however, every effort will be made to minimize disruption.

The trees most likely died from White Laminated Rot (Ceriporiopsis rivulosa) and replaced at a later date with a different species of tree indigenous to the region. 

Notice of Tree Removal – February 2016

UBC’s arborist has identified five Douglas Firs (Pseudotsuga menziesii), located on the west side of West Mall Annex (north of the First Nations Longhouse) that are dead. They recommended that these trees be removed because they pose a risk to the public and surrounding buildings.

Due to the cultural significance of this site to many groups, and its proximity to offices and classrooms, we want to let you know about the planned removal of the dead trees in advance. Removal is scheduled from February 15-18 to coincide with Reading Break. Some pedestrian areas may need to be cordoned off, however, every effort will be made to minimize disruption.

A yellow ribbon wrapped around each tree identifies the five that will be removed.

The trees died from a root fungus called Armillaria. Some of the surrounding Douglas Firs are also infected by the fungi and are not curable. They will also have to be removed over the next twenty years as they die and become a risk.
