Report To: General Government DG3ODLJDGHHORS PHWRPPLWWHH Date of Meeting: -DDU Report Number: OPD -001-19 Resolution: JC -028-19 File Number: By-law Number: Report Subject: Update on the Replacement of Emerald Ash Borer (EAB) Infected Trees Recommendation: That Report OPD -001-19 be received for information. Municipality of Clarington Report OPD -001-19 Report Overview Page 2 This report provides an update on the current status of the removal/replacement of Ash Trees that are infected with the Emerald Ash Borer Beetle (EAB). 1. Background 1.1 The tree inventory count that was completed in 2013 for the urban areas of Clarington indicated that there were a total of 2,344 Ash trees located on municipal road right of ways. 1.2 This inventory was split between three main urban centers as noted below: Courtice 981 trees Bowmanville 1,126 trees Newcastle/Orono 237 trees 1.3 Work has been on-going by staff of the Operations Department since 2013 to remove all of the Ash trees located on municipal roads. The remaining Ash tree count is provided as follows: Courtice 0 trees Bowmanville 259 trees (as of Nov20/2018) Newcastle/Orono 237 trees 1.4 In late, 2017 Clarington forestry staff began to remove the 515 Ash trees that were situated south of Highway #2 in Bowmanville. At present, only one remains which will be removed once Bell has removed their temporary service wire. 1.5 Of the 611 Ash trees in Bowmanville that are located north of Highway #2 a total of 259 currently remain to be removed. These were scheduled to be removed prior to the end of 2018, but have been delayed due to several extreme weather events. Most notably the recent wind event on September 21, 2018, which generated 120 work orders for storm damaged emergency tree service calls. The current projected time -line for the remaining EAB removals in Bowmanville is late spring or early summer 2019. 1.6 At the current rate of removal the 237 Ash trees that have been inventoried in Newcastle and Orono can be expected to be taken down no later than the early part of 2020. 1.7 At this time, the Operations Department does not have an inventory of Ash trees that are located within greenspaces, natural heritage areas or on any of the rural road allowances in the Municipality. As concerns arise the inspection and removal of these Ash trees will require additional staff time or require contracted services. Typically these issues, however, are only dealt with when they present an immediate hazard to persons or property. A closer review of these areas will need to be performed following the completion of the urban street tree removal program. Municipality of Clarington Resort OPD -001-19 2. Replacement and Stumping Page 3 2.1 The replacement of ash trees began in 2014. At this time all of the 981 ash trees that have been removed in Courtice have been replanted with a variety of native type species. Based on the current budget levels that are approved for this initiative all of the ash trees that will be removed from Bowmanville, Newcastle and Orono are anticipated to be replanted by the end of 2022. 3. Emerald Ash Borer Cost to Date 3.1 The current cost of the Emerald Ash Borer removal and replacement program to date is: Wages $1,037,135 Equipment 390,472 Contract services 1,367,011 Total $2,794,619 Due to the fact that Municipal resources have been primarily focussed on the removal of ash trees, Operations staff are not able to respond to less critical forestry tree requests such as non-essential pruning. As noted earlier, only those forestry requests that are considered an emergency will be attended to on a priority basis. 3.2 If we were to increase the funding for replacement of the remaining 1363 affected ash trees in Bowmanville, Newcastle and Orono over the next two years we could expedite the time of replacement to the fall 2020. Based on an average cost of $365 per tree for stumping and replacement this would mean a one-time budget increase of $267,860 to complete the replacement program by 2020. 3.3 Once the tree removals are completed in the urban area, staff will concentrate their efforts on the removal of the affected ash trees in our parks, green spaces and rural road allowances. These trees are quickly becoming a concern as they continue to decline which will result in an increasing number of emergency and storm damage removals and calls. The probability of personal injury and property damage will increase the longer we delay the removal of these trees. 4. Conclusion The Operations Department will continue to focus on the ongoing removal of ash trees affected by EAB in order to meet our currently expected completion target date in the fall of 2022.
