Progress
Report of On Site Work -
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).

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.
