Progress Report of On Site Work - Uplands Park

August 31, 2005

 

It was not possible to strictly follow the list of priority sites outlined in the management plan because of logistical considerations. Sean Novak is only available on certain days and without him the crew cannot use a chain saw to cut the invasive trees (English hawthorn, Norway maple, European ash). Species that require a cut stem treatment (gorse, blackberry, large daphne) can only be removed when Sean or another person with a permit to use herbicides is on site.

 

The crew includes the arborist (Sean), arborist’s assistant (Sean), botanist (Carrina), crew leader (Chris) and crew (Eric, Rob and Gillian).

 

August 29

  • The entire crew was given an on-site orientation including:
    • Brief orientation to the park, the sensitivity of the site and the purpose of the work
    • Explanation of how areas with rare plants will be flagged and how to avoid these areas during work
    • Explanation of how plants slated for removal will be flagged
    • Guidelines for using the chipper including safety precautions
    • Identification of invasive species that will be removed and comparison to similar native species
    • Demonstration of invasive species removal to minimise resprouting and how approaches will differ for different species depending on whether they resprout or not
    • Logistical discussions of access routes and priority sites
  • Two large and one small English hawthorn trees were cut down with the chain saw and chipped next to the trail just south of Location #2 (although these plants were not directly in one of the priority areas, their berries will fall into Location #2 and it was useful to have an orientation not directly next to species at risk). Rare species in the area were flagged first.
  • Broom, daphne and small hawthorns south of Location #2 were cut with loppers, the cut stems of the daphne and hawthorn were painted with diluted round-up and the stems were chipped.
  • The locations of the yellow montane violet and foothill sedge were flagged and the giant hogweed plants from Location #1 were removed with direction from the botanist to remove as much of the rootstalk as possible. The plants were put in plastic garbage bags and removed from the site.
  • Broom was cut in Location #11 southeast of the eastern meadow. Blackberry was not removed because the arborist was not on site.

 

August 30

  • Broom cut in Location #11 was hauled on tarps to the chipper at a location accessible from Southdowne road.
  • At location #2, in the southern section of the central meadow, large hawthorns were cut with a chainsaw. Small hawthorn, broom, large daphne, small European ash were cut with loppers. The cut stems of all except the broom were painted with a dilute solution of round-up. The cut material was chipped at the southern edge of the central meadow and all material was carried by hand to the chipper. The locations of the rare species were flagged and cut plants were not carried through this area. Further work is necessary in this area.
  • The botanist cut large broom in the central meadow next to species at risk. This was carried on tarps to the southern edge of the central meadow and chipped.
  • Broom is still piled in the central meadow for later chipping since further work is required in this area.

 

August 31

  • Crew removed large broom from Location #12 in the eastern meadow. The hawthorn was not removed since the arborist was not on site today. Further work will be required in this area. The rare plants were flagged and the botanist removed broom within the flagged area. The cut broom was removed using a tractor and trailer close to the NE fire hydrant accessible off Southdowne Road.

 

The vast majority of the people we have talked to while working in the park have been incredibly supportive of the work once we have explained what the intentions are. In fact one older couple offered to volunteer with the crew and two others asked about other future volunteer opportunities for invasive species removal in the park. To date, there has only been the single complaint from Kathleen Mathews. Although the botanist, arborist and crew leader did try to explain the approach and reasons for the work, it seems Ms. Mathews concerns stem more from an ideological difference that does not approve of invasive species removal in general rather than the specific approach taken.

 

Matt Fairbarns, the botanist who surveyed the rare plants in the park and helped draft the HSP proposal, toured the site with the botanist on August 31st and approved of the work conducted to date. Before work began, he read a draft copy of the management guidelines written by the botanist and his suggestions have been incorporated into the working version and the current approach taken.
