i'm doing a final project for school...i've picked two sites with old growth and second growth forest stands...basically i'm comparing wildlife tree characteristics of 2nd growth vs old growth and proposing to implement a plant creating wildlife trees in 2nd growth.... Have any of you guys made wildlife trees? I've researched some interesting stuff...one guy in washington helped pioneer this... he climbs up suitable trees, tops them, makes the top jageed (allowing for more bug infiltration) and even bores or cuts flanges in to tree (or whats left of it ) for bat and bird habitation etc...another guy here in bc studied wildlife tree creation by a) having a climber climb the tree and drill into the core, inserting a wooden dowel innoculated wtih a fungus or b) actually shooting the tree with bullets containing a similar wooden dowel...
 
I'm just curious to know, is it more typical in northwest conifer forest to have a shortage of good aboreal wildlife habitat? Here in the northeast the hardwood forests have plenty of good habitat. 90% of the woods are second growth and there is no shortage of trees with either dead limbs, hollows or broken off leaders. In other words nature does an excellent job. Quite a challenge to improve on it.

If there is a situation where all the trees are in an area are in such pristine condition that there are no diseased or damaged trees I'd think that simply girdling a tree would provide what's needed. I guess it depends how fast you're trying to break a tree down. If you'd rather have the tree partially alive you could girdle the tree half way or 2/3's up or girdle selected limbs. You could pretty much tailor a tree to exactly what you need that way. It seems excessive to go to the trouble of introducing fungus with projectiles. If you simply strip a section of bark off that would get things started. Maybe there's something that I'm missing.

Interesting question for a group of people (arborists) who are always trying to accomplish exactly the opposite of what you're talking about.

The wildlife attracted are smaller species.

I just had a pair of hooded mergansers visit my pond; first time I saw em. I have an old sweetgum at waters edge and I'm debating wheter to install a duck bos on the side or to make a cavity inside. thoughts?

I know I may be casuing the tree to break over in a decade or two, but I'm intrigued by the notion of giving them some more genuine habitat. Then again they may not move in and the tree may fall sooner than I'm thinking it will.

HMMMmaybe the duck box is the way to go.
 
there are dead/dying trees in the 2nd growth forests here (coniferous of course) but they often lack the suitable characteristics ie internal decay, cracks, suitable size etc... that are found in the older growth forests.... in the old days wildlife trees (snags) were felled for safety reasons, so the regen forests lack these structures.... wt's (wildlife trees) offer habitat, feeding, or breeding grounds for alomost 2/3 of forest birds, and these birds are very particular.... so mimicing these characteristics in 2nd growth is thought to bring these stands to a more natural state...it has been studied that topping and/fungal innoculation was the quickest and most efficient way to promote the desired characteristics of decay and infestation...plus thinning these stands also brings the stands closer to a more natural state by enhancing vegatative undergrowth to grow for deer,elk, and their predators...
 
I have made many "wildlife" trees for the municipality of Surrey (Jak-did you hear the one about the Surrey girl who....) yes, that Surrey. Basically you just climb up and strip and chunk to the hieght they want, usually 20'-40', and girdle the tree. They want you to make the top look like it was hit by lightening with an 020, better to tie a rope high, put in a cut 1/2 way through and come down, then rip off the top, it chairs up and looks realistic. You can also cut holes for birds with your saw. I know poeple have used drills as well. I think it is a good idea, after the rot sets in the tree is a home to bugs and then birds that eat them. Helps to encourage all wildlife really. Making these trees is one of the reasons I have big problems with ISA arborists. Like I said it is a good idea, IN THE RIGHT PLACE. These jokers have "wildlife" trees in all kinds of bad places, leaning over playgrounds, private backyards that border on city property, trails and so on. Basically you are making a snag, sooner or later they fall. Well do I remember driving into a park and cutting down one of these rotten old man made snags with a boom, and the little kid and his grandpa watched me-the p.o.s. was leaning heavily over thier backyard. Like I say, the right place morons.
 
good idea ripping it off for a more realistic look and a jagged top does open more area for bug and decay infiltration...thanks for that...i think a lot of the difference of ideas comes from where you're from... as i mentioned before, i'm from small town northern vancouver island....surrounded by forest... and i think people from these places have a more casual approach to trees.... i did some work for a friend of mine as well as my father in law (both work for the forest industry) and i mentioned my desire to learn spurless climbing... they looked at me very puzzled,,, and asked why would i want to do that!
 
I really don't think the fungal innoculation is necessary, fungal spores are pretty much ubiquitous. If you do pursue this- you say you want to "implement a plant" ( I assume a typo)- you might also consider the forest type that you are trying to mimic. Second-growth nearly pure Doug fir compared to spruce/hemlock compared to whatever, depending on where you are. Also, you might consider the artificial maturing of individual trees that might be more inclined to fail already, perhaps trees with a deeply included codominant or a sharp directional change in a stem. Most important, though, you better know what you're doing. I'm sure that clearance guy can tell you the dangers of dumping out whole tops on big trees in forests, even while he curses you for caring about this stuff at all.
 
Jak-snags still get cut down in logging shows for safety reasons, thank god. Just not in parks, at least in my limited experience, another thing that chokes me about the ISA jokers I dealt with. I guess little kids and everyone else in the park can take the risk. If they had the trees that are dying, on the way out, wildlifed to a proper height or cut right down, depending on location that would make some sense. Trees4est, if you had looked in my first post you would see I think wildlife trees are a good idea. Of course I don't curse him for trying this out, why so quick to assume these things? And Jak has windfirmed trees, I think he knows all about blowing of big tops in the bush. You see 4est I am a conservationist, that is all I do now, looking after creeks, haven't cut a tree down for months. At work anyways.
 
i actually don't plan to implement the plan...my report is more of a proposal study...if a company caught me dumping tops in their tfl, i'd be in pretty deep... however i would like to eventually get some work out of it... as for the fungal innocualtion, one fellow said it worked the best after he studied it... myself i'd rather dump the top... more fun than drilling holes... jeez clearance no love for you on this site eh! Ha ha! Regardless, i find your posts the most entertaining!
 
Fascinating topic. The first post I thought was a bit silly - unnecessary and all that. But as you guys explained more about the second growth characteristics it made more sense.

It sounds kinda fun and, like Clearance said, if in right place/time it would seem rather rewarding.
 
Clearance... dude!!! It's impressive the way you can turn any thread into a rant against residential arborists and the ISA. You've got some deep hurt there. :cry: :)

1I'dJak, here's one way trees get internal rot in the city. I live near a curvy 4-lane parkway lined with red oaks tight to the curb. Every single one of them, probably a couple of hundred trees has been hit by a car. And nearly every one that's been hit is rotting from the bottom up, inside out. Since it's not practical to drive a car 60 miles per hour into a tree for the project you could simulate the effect with a saw and axe. Split a rectangular slab out of the trunk about 5 inches deep, 2.5 feet high across the trunk. Cut it low or high on the trunk, the effect will be the same: guaranteed to rot out the interior of the tree.

Yeah, hit reply and left the computer, so I wrote it before I read your post. I'm just making an assumption because you seem to rail on hippies and conservationists and maybe everyone in the ISA. But because your ideas and my ideas of conservation might not be the same, you're right, not fair to make assumptions.
I didn't catch where Jak has windfirmed trees. Which off-topic I guess I was wanting to ask about. Is that riparian edges of clearcuts or something? Like tapering forest edges? Just curious.
 
roger...along riparian edges, cut block edges, wherever there are trees exposed to high winds...forest industry has finally got it...i've done it in 2nd growth doug fir stands...i think clearance does is on old growth in the queen charlottes, which would be a trip... i'm still fairly new to it, clearance is the man concerning firming... but i'm looking forward to the next show i get to go to!
 
Clearance or Jak - has either of you read "The Golden Spruce?" I don't recall the author. You probably know the story.
 
Jak-thanks for saying I am the Man. Moss, I can't turn everthing into a ISA slagfest, this subject was made for it. And to correct you, ISA arborists are not residential arborists if they work for a city or municipality, they are dealing with trees on public land not residential land. When I started doing treework (for want of a better term) in populated areas I, like many others thought that the ISA tag meant something. When you call an electrician, if he (or she) holds the trade certificate you can be more or less sure that the work they do will be done properly, like your house won't burn down, for example. When a municipality or city employs an arborist people assume that these people will do what is best for the trees and of course not cause unnecessary risk potential to the citzens of that place. However, ISA certification is really not much better than those ads you see, become a legaly ordained minister". Yes you have to sit down once and write a test, after that you just keep feeding them money. So, when I had worked for that city indirectly for a while and saw all kinds of crazy stuff done at the behest of these people, I realized that this certification was a joke. It is an illusion, smoke and mirrors, a scam. Many times I showed up to do something to a tree and the people who lived under/beside p.o.s. trees thought we were there to cut down "the" tree. It is my contention that the citzens of Surrey B.C. have more of a clue than the city arborists. I know that there are very good treeguys that are ISA, just a roll of the dice on what people get. This is just not good enough when people are in parks or on thier own property living under trees that should be cut down. Everthing I said about the "wildlife" trees, snags is true, funny how people give me a hard time for calling b.s. on the ISA, never the things they do, or neglect to do. 4est-big diff. between conservationist and preservationist, which is what the hard core treehugggers are.
 
never read the book but remember when all that went down... pretty amazing... the guy who did it was pretty hardcore... i think he did it to protest the current forest practices and ended up ticking off the hadia indians... and i think he ended up going missing....
 
I admit to knowing nothing about all of this. But since its a school project, would you include text about the possibility that if you introduced ANYTHING (fungus) into the stand, that you might singlehandedly created the next disease that wipes out the entire population?

Just a thought.
 
good point... althought i think the guy who did this project just used existing fungus from the stand... i don't think he would've been allowed to do this if he was introducing some virulent strain, but i should ask the guy if this is a concern...thanx man

This is the common practice, why buy something if you have it on hand.

I've done it where we took branchrot and rubbed it in the cuts. Often you can find it in the tree you are in.

The few times I've made habitat was in hazard reductions where people did not need the whole tree taken out. It was put in the bid to take the tree to a certain hight, leaving stubs and boring holes. Three cut plunge and pop out the plug.


One fellah I know keeps a carving bar for the purpose.
