1000 posts and counting??



1000 blog posts and counting?

To what shall I compare this life of ours?
         Even before I can say
         it is like a lightning flash or a dewdrop
         it is no more.

Seems to me not so long ago that I started to write in my blog about 
our garden in Guildwood, flowers, garden books, my trips, invasive plants and insects. 
Invasive plants including Dog-strangling vines   
(black swallowwort and pale swallowwort ) and Phragmites (common reed or European Reed)
threatening Ontario’s biodiversity 
Insects especially the Emerald Ashborer EAB (Agrilus planipennis) 
destroying thousands of trees in Ontario and Quebec.
Another very invasive beetle the Japanese beetle (Popillia japonica) creating havoc in our gardens.
I wrote about the  environment, my concern about pollution and started cleanups
along our shoreline of Lake Ontario and parks in 2007

Discovered the first lichens in our parks and I started to learn more about them.
Nature fascinated me more and more...
The garden blogger community around the world inspired me to create new spaces around our house.
I am very grateful for your visits and thank you for your comments.
Facebook, Pinterest and other social platforms have replaced many blogs but
I believe that there is room for a blog like mine showing how beautiful our nature is.

The collages below - a small collection of pictures from the past 10 years ... enjoy!!

Coyotes and the Emergence of the Coy-wolf





Today, I joined Rouge Park leader Christine to learn more about

'Coyotes and Coywolf' populations in our parks and neighbourhood.

Coywolves are canid hybrids of wolves and coyotes. They eat small mammals such assquirrelsmice, birds, snakes, lizardsdeerand livestock, as well as insects and other invertebrates. The coyote will also target any species of bird that nests on the ground. Fruits and vegetables can form a significant part of the coyote's diet in the summer and autumn. Part of the coyote's success as a species is its dietary adaptability. As such, coyotes have been known to eat human rubbish and domestic pets. Urban populations of coyotes have been known to actively hunt cats, and to leap shorter fences to take small dogs.  
I have seen coyotes on several occasions while hiking along the Scarborough Bluffs. Always left the area without encountering any problems. 
But have I really seen coyotes? 
On 31 March 2010, a presentation by Ontario Ministry of Natural Resources research scientist Brent Patterson outlined key findings that most coyotes in Eastern Ontario are wolf-coyote hybrids and the Eastern wolves in Algonquin Park are, in general, not inter-breeding with coyotes.
*******
During our walk through this area of the Rouge Park, we did not see any traces of coyotes or wolf- coyote. They can be mostly seen during the early morning hours or at dawn.


 Der Kojote Mischling“; lat. Canis latrans), auch bekannt als „(Nord)amerikanischer Präriewolf“ oder „Präriehund“ (nicht zu verwechseln mit dem Nagetier Präriehund), ist eine in Nordamerika verbreitete wilde Art der Hunde, die einem kleineren Wolf ähnelt.











If you drive through Toronto you discover dead trees infected and killed by the emerald ash-borer (Agrilus planipennis). A green beetle native to Asia and Eastern Russia. Outside its native region, the emerald ash borer is an invasive species, and Emerald ash borer infestation is highly destructive to ash trees in its introduced range.
We also discussed wildflowers I was able to identify, photograph and  published in my post.

 
 


The interesting deformations on sumac trees we discovered and  I was able to identify at home as Sumac galls. 

Another very interesting find:
A live Paper Wasp nest.... 

Spotted Touch-me-not - Orangerotes Springkraut (Impatiens capensis)
Another beautiful wildflower - Impatiens capensis, the Orange Jewelweed, Common Jewelweed, Spotted Jewelweed,  or Orange Balsam,  found along the Woodland Trail , Rouge Park; is an annual plant native to North America. 
Thanks Christine!!
I enjoyed my walk today and hope to join you again.
 Interested to join guided walks in our Rouge Park?

Emerald Ash borer (EAB)-Agrilus planipennis and Red-headed Ashborer - Neoclytus acuminatus

Emerald Ash-borer
I am publishing this post because of many discussions in our neighbourhood.
Questions deal with the detection of the infestation and what to do or protect our ash trees.
Hope the links provided will help to clarify some of the issues surrounding
the infestation of our ash trees in Guildwood.
 
 
The Emerald Ash-borer (EAB) has been discovered in many areas in Canada and the USA.
Agrilus planipennis or Agrilus marcopoli, native of Asia.
Below: Collage shows the damage the beetle causes on trees.
The Emerald Ash-borer has killed millions of ash trees in southwestern Ontario and other areas. Now the beetle has been found in Guildwood as well. The infestation poses a major economic and environmental threat to urban and forested areas. The cost of removing infested trees is quite substantial and a financial burden to many home owners. What can be done to save our trees?

I have found excellent websites about the Emerald Ash-borer includes advise about insectizide options for protecting Ash trees:
http://www.emeraldashborer.info/index.cfm
This Web site is part of a multinational effort in Michigan, Illinois, Indiana, Iowa, Kentucky, Maryland, Minnesota, Missouri, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, Wisconsin, Ontario and Quebec to bring you the latest information about emerald ash borer.

The City of London, Ontario published this identificatonguide:

Collage shows the exit holes made by Emerald Ash-borer on one of the ash trees in our neighbourhood.
Recently the beetle was spotted on our porch.
Red-headed Ashborer
Neoclytus acuminatus

We park our car quite often close to a very large and old ash tree in front of our house.
The tree is about 60 -70 years old and showed some decline during the past 15 years.
Dry branches have been removed or broken off.
One day we found an very interesting beetle in our car.

After searching for this beetle on the internet I learned that this is indeed a native Ashborer in Ontario.
Now, I have found more signs of the Red-headed Ashborer.
After taking pictures of infested trees in Robert Bateman Park (a.k.a).Kate Gardener Beltline Park, Toronto I received a comment on my Guildwod Village Blog confirming the Red-headed Ashborer.
Both beetles cause the same damage on trees but look totally different. (see pictures)
Please compare:
Emerald Ash-borer exit holes are most likely to be D-shaped and 3 mm - 1/8".
Red-headed Ashborer exit holes are round and about 6 mm -1/4" .

Der Asiatische Eschenprachtkäfer gefährded alle Eschen in den USA sowie in Canada.
Große Gebiete in Nordamerika sind bereits befallen.
Aller Wahrscheinlichkeit wurde der Käfer mit Transportpaletten aus Eschenholz von China in die Vereinigten Staaten eingeführt. Von dort breitete er sich schnell aus.
Es wird befürchtet , dass der Käfer sich im gesamten natürlichen Verbreitungsgebiet
der Gattung Fraxinus in Nordamerika etablieren könnte.
