[CANUFNET] Tree "Sexism" in Canada: Call for information & thoughts

[ISA Prairie Chapter]

Bees are pests?

If the readers of this article start to believe that bees are pests, there
is not much hope for the human race in the long run. We need all of our
pollinators.

Subject: [CANUFNET] Tree "Sexism" in Canada: Call for information & thoughts

 

Hello everyone,

 

We at Tree Canada just received some questions from a reporter at the
Guardian, and I thought it would be good to share with the wider urban
forestry community. Please do contact Ally Hirschlag directly with your
comments.

 

Context:

"Male trees are cleaner and easier to manage than female trees. Unlike their
female counterparts, distinctly male plants produce pollen but do not
produce seeds, pods and fruit, which fall to the ground and create mess.
Female trees also attract pests, including bees, because they provide a
source of food."

"Commercial horticulture produces vast numbers of all-male clonal selections
from dioecious plants [.] Close to 100% of all the ash (Fraxinus), poplar
(Populus), pistache (Pistacia), bay laurel (Laurus), junipers (Juniperus),
willows (Salix), gingko tree (Gingko), Griselinia (Griselinia), mulberries
(Morus), yellowwood (Podocarpus), locust (Gleditsia) and logwoods (Xylosma)
sold are clonal males."

snippet&q=clonal%20males&f=false> Source

 

The questions:

*	In Canada, has there been a significant proportion of entirely male
trees or male clones planted in urban areas? Why has this trend been
perpetuated?
*	Has this caused an uptick in pollen dispersal in urban communities?
*	Do you know of specific communities in Canada looking to lower their
pollen count by adding more female trees and/or less allergy-causing
pollinators? 
*	What else are communities in Canada doing to combat worsening
allergies in urban or suburban areas due to high tree pollen counts?
