<DIV><SPAN class=135131420-12022010><FONT face=Arial>With regards to the
importance of hedgerows, they provide a number of benefits, particularly in
fragmented landscapes comprising a mosaic of separated habitat
patches.</FONT></SPAN></DIV>
<DIV><SPAN class=135131420-12022010><FONT face=Arial></FONT></SPAN> </DIV>
<DIV><SPAN class=135131420-12022010><FONT face=Arial>It has been proven, both by
scientific research and by many years of observation, that
hedgerows provide habitat function (e.g. corridors, cover, foraging, etc.)
for various wildlife species travelling between habitat patches as well as for
species that are adapted to open landscapes (There are in fact certain bird
species in Ontario that are predominantly found in hedgerows).
H</FONT></SPAN><SPAN class=135131420-12022010><FONT face=Arial>edgerows can also
contribute to genetic diversity within habitat patches adjoined by vegetative
linkages such as hedgerows due to transfer and seed dispersal (excretion, food
caching, etc.) by species moving between habitats. In Ontario at least,
hedgerows have by default allowed certain tree species to avoid being killed
from area infestations. For example, a number of Elm trees now surviving
in hedgerows have escaped the spread of dutch elm disease due to their
isolation from main forests where infestations were greatest and easily
spreading from tree to tree. M</FONT></SPAN><SPAN
class=135131420-12022010><FONT face=Arial>any hedgerows in rural areas also
contain piles of various sized boulders cleared from adjacent farm fields
which offer ideal refuge for resident or transitory snakes, insects and small
mammals. Obviously, hedgerows can also play a significant role in reducing
topsoil erosion by reducing wind velocities across open fields. In general, the
wider and more plant diverse and dense a hedgerow is, the more
important it is likely to be for fucntional ecological
purposes.</FONT></SPAN></DIV>

discussed above. Hope this helps.</FONT></SPAN></DIV>

Content-Type: text/plain; charset="iso-8859-1"<BR>> <BR>> To Whom It May
Concern:<BR>> <BR>> For the past few years the City of Edmonton has been
experiencing an outbreak of black knot (Apiosporina morbosa). Edmonton's urban
forestry unit, River Valley Forestry and Environmental Services (RVFES) has
been responding by pruning out the visible fruiting bodies, and by removing
trees that are beyond saving. However, if we continue these practices we will
eventually end up removing thousands of our valuable ornamental trees of the
genus Prunus. So, we are asking other municipalities about their experience
with this fungal pathogen and what steps they have taken to battle black knot.
RVFES would greatly appreciate if you could aid us in our fight against black
knot by taking the time to answer the following questions.<BR>> <BR>> *
Does your region have problems with black knot? If so do you have a campaign
or strategy for combating it? If yes, how do you communicate your strategy to
the public, and what do you do to encourage citizens to take care of black
knot on their own trees?<BR>> * If your municipality does treat for black
knot, what treatments were and were not successful?<BR>> * How serious is
black knot mortality in your municipality?<BR>> * Aside from Amur cherry,
do you know of any black knot resistant varieties? Have you had success with
any of these varieties?<BR>> * How does your municipality dispose of
infected material?<BR>> * Has your municipality tried or had any success
with the biological control agent, Trichothecium roseum (fungal
parasite)?<BR>> <BR>> <BR>> Thank you for you time,<BR>> <BR>>

Content-Type: text/plain; charset="us-ascii"<BR>> <BR>> We have run a
black knot program the last 10 years when southern Alberta<BR>> started to
have major issues. <BR>> <BR>> <BR>> <BR>> 1. We inspect all
public cherries in early May (before leaf) and<BR>> again in August (for
new infections)<BR>> <BR>> 2. If a plant is found we perform a
concentric survey inspection<BR>> of both public and private parcel
cherries and hand out information<BR>> leaflets to home owners<BR>>
<BR>> 3. We inspect all nursery stock we buy and what the local<BR>>
greenhouses/vendors buy in May<BR>> <BR>> 4. When an infected tree is
found we find out where the tree was<BR>> bought (so far with the exception
of a few Canadian Tire trees most have<BR>> been from respectable
nurseries)<BR>> <BR>> 5. Amur still get black knot here<BR>> <BR>>
6. We deal with the diseased wood the same as noxious weed seed<BR>> heads.
Landfill it and ask for "immediate cover"<BR>> <BR>> 7. Black Knot
hasn't been nasty enough here yet to trial any<BR>> biological controls and
most trees are found before more than a few<BR>> braches need to be removed
so tree mortality is at 1 or 2 per year.<BR>> <BR>> 8. These measures
have kept BK under control so far however the<BR>> number of cases has
doubled each of the last 3 years so what really has<BR>> to happen is
better regulation in the nursery trade. Hopefully the<BR>> Nursery
Certification Program continues to gather momentum.<BR>> <BR>> <BR>>
