Hi
Perhaps ask the folks at Norfolk
<http://www.norfolkalus.com/index.php?option=com_content&view=article&id=21&
Itemid=13> ALUS Pilot Project - Alternative Land Use Services what they
have. E.g. their
<http://www.norfolkalus.com/index.php?option=com_content&view=article&id=21&
Itemid=13> demonstration project page mentions "1.39 acres of pollinator
habitat in the form of Pollinator Hedgerows - perhaps the most
groundbreaking effort of the Norfolk Pilot, the pollinator hedgerow is aimed
at finding solutions to restore populations of native pollinators."

Hello Sue,
With regards to the importance of hedgerows, they provide a number of
benefits, particularly in fragmented landscapes comprising a mosaic of
separated habitat patches.
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). Hedgerows 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.
Many 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.
I have attached a couple interesting scientific articles I was able to
quickly pull from our electronic resource library that elaborates/touches on
some of the befits I discussed above. Hope this helps.

I need some good information on the importance of hedgerows in an eco
system. Can anyone point me to some good information that comments on
wildlife, insects, small trees and bushes and their interrelationship with
large trees, farmland etc.?

> 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.
>
> * 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?
> * If your municipality does treat for black knot, what treatments were and
were not successful?
> * How serious is black knot mortality in your municipality?
> * Aside from Amur cherry, do you know of any black knot resistant
varieties? Have you had success with any of these varieties?
> * How does your municipality dispose of infected material?
> * Has your municipality tried or had any success with the biological
control agent, Trichothecium roseum (fungal parasite)?
