[CANUFNET] Hand pull testing

Mon May 1 16:46:18 EDT 2017

Rob,

We do have considerable experience with engineering based tree risk
assessments using pulling tests. I would be very happy to discuss this
further with you if you want to contact me directly. My contact information
is below.

Sincerely,

One tree pulling guru (at least in eastern Canada) is Philip van Wassenaer
of Urban Forest Innovations in Mississauga, ON.  I would try there.

Although it's about buildings, this organisation has proven to be
outstanding for wind simulation and parameters, probably adaptable to mature
and héritage trees.

HI Rob
what size tree?
on small trees  = if cannot pull out with healthy tug by an adult who is
monitoring the planting.
Note Blow downs of mature trees occur at 60-80 km per hr Alice

Hi All,

Does anyone have any data or guidelines for replicating a force on a tree
when performing a hand pull test? As part of our advanced risk assessment
techniques, we will perform a hand pull test on smaller trees to assess
soil, root or trunk movement. We're curious as to the amount of force
necessary to adequately represent a wind speed of up to 80 km/h. Any
information on this subject would be appreciated.

Thanks,

ROB RENY | COORDINATOR, URBAN FORESTRY
