play00:01

So we're here in the pando clone.

play00:03

People drive through it, don't even realize they're in the pando clone.

play00:06

Or we'll get phone calls and people really wondering what is this pando clone and it's

play00:13

an aspen stand here on the Fishlake.

play00:16

You have highway 25 that goes right through the middle of it.

play00:20

The pando clone is 106 acres.

play00:24

Scientists say there is an estimated 50,000 trees here in the pando.

play00:28

The interesting fact about the pando clone is that scientists are claiming that it's

play00:32

the largest living organism in the world that has been DNA tested.

play00:38

So there might be other larger organisms but based on DNA, this is the largest living organism

play00:44

in the world.

play00:46

The pando clone is as the latin word frames it as "I spread".

play00:51

The problem with the pando clone it's not that necessarily that the overstory is dying,

play00:56

or some of the clone is not doing well, but we're not getting any regeneration to replace

play01:00

the parts that are dying.

play01:03

So from a Forest Service perspective, yeah, that's a problem.

play01:08

When there's no regeneration to replace those that die.

play01:11

This behaves in a lot of ways like any other aspen stand.

play01:15

They get old, they die, new stuff comes up to replace the old.

play01:19

And in this case, the old stuff is dying, there's not much new stuff to replace it.

play01:25

Typically we would expect aspen stands should be able to regenerate on their own.

play01:29

I've heard it estimated by scientists that this stand could be upwards of eighty thousand

play01:35

years old.

play01:36

That's a guess, but it gives us an indication that they're very, this stand is very old.

play01:41

And when you see the pando, there's no regeneration for the most part occuring and that's not

play01:50

typical of what you would expect from an aspen stand so, that's the problem is the root systems

play01:56

are not sending up the succors or if they are, they're not having success in being able

play02:02

to grow into mature trees to perpetuate itself.

play02:06

Yeah, so, that's why we're doing this study, we have a theory, that herbivory is playing

play02:14

a role in it, as the plants come up.

play02:18

They're browsing the plants off.

play02:22

And so that's one reason.

play02:24

Another thought is that the pando is just old.

play02:30

And doesn't have the energy reserves to send up succoring.

play02:33

Other ideas are that it has fungus and a type of fungus that's causing it's problems.

play02:43

Just one other item too is that aspen stands like disturbance.

play02:48

When they're disturbed through fire, mechanical, different types of treatments, they regenerate.

play02:54

And so that's, those are the things we're looking at with the pando clone to try to

play02:58

figure out why it's not regenerating as well as it should on it's own.

play03:03

The fence that we've placed around portions of the pando clone, there's 106 acres and

play03:08

we've fenced off approximately 90 acres of it.

play03:12

To remove the browsing issue.

play03:16

The cattle and the deer.

play03:19

And to be able to see what role that was playing in this.

play03:24

Then we can compare it to areas that are not fenced off.

play03:28

And get a better feel for the browsing part of it.

play03:32

So the fence was to address the grazers.

play03:36

So as you know when you run some scientific tests, you try to eliminate something so you

play03:42

can get a better or a more accurate reading on what that test is.

play03:45

So I think what we're going to find as we do the studies in here, although the grazers

play03:51

may play a role in it, they aren't the only thing that's causing the decline.

play03:56

There are different varieties of beetles, bores, some of these trees here, with the

play04:02

black on them and what not are caused by a bacterial infection.

play04:08

When we had our insect and disease specialist here, she suspects this is what's called shephards

play04:13

crook, caused by a fungus that's effecting the regeneration, or atleast the top leader.

play04:19

The top leader would be something like this.

play04:20

This is your top leader.

play04:23

So it effects it.

play04:24

Comes down to about this point here on the tree, causes the top of it to bend over like

play04:29

this called shephards crook.

play04:32

So some of that is going on in here, not affecting all of the regeneration, but some.

play04:39

So there was a prescribed burn, removal of juniper.

play04:44

Which the suspicion there is that the common juniper that you're seeing here competes with

play04:49

and or can outcompete regeneration and the third one was selective cutting to remove

play04:56

some of the overstory to promote succoring.

play04:58

So those are the three things we're trying right now and we'll see how that shakes out.

play05:03

This is likely a regeneration response from the burn that was done in the spring of the

play05:09

year.

play05:10

Like all aspen stands, they function as clones.

play05:14

So they reproduce by succoring.

play05:17

So the root system under the ground is all one family or they all are of the same DNA

play05:25

makeup.

play05:26

And so that's how all aspen stands are.

play05:29

A clone all looks the same.

play05:31

Basically they, when they leaf out in the spring they do it at the same time, and as

play05:36

you look out across the landscape you'll see one clone leafing another clone next to it

play05:40

not leafing in the fall when they change colors.

play05:43

The clone will typically look the same and then be different than another clone right

play05:48

next to it.

play05:49

So you can, just by looking at a clone kind of begin to say that's an aspen clone in itself.

play05:56

Certainly aspen is an important plant community and species that we have on the Fishlake and

play06:03

on most of our forests.

play06:05

We look at the aspen as a keystone species for what they provide on the landscape, aspen,

play06:12

they're highly productive areas, they have high diversity in plant and animal life, they

play06:17

are important to our watersheds.

play06:19

And so as managers and as scientists, we want to understand how aspens function so that

play06:26

we can make good decisions in the way that we preserve and utilize our aspen stands and

play06:33

because pando was assigned a name and people have taken interest, we decided on the Fishlake

play06:39

that it was important that we preserve the pando clone and try to better understand how

play06:45

it functions and also to understand the problems that the pando's having.

play06:49

I think that's a role we have as land managers to be mindful of the uniqueness of this area

play06:56

and try to sustain it.

play06:58

The goal obviously is to maintain the pando clone.

play07:02

And from my perspective that's always meant not just maintaining it for us here, but our

play07:08

kids and their kids because the mission of the Forest Service is to maintain these types

play07:13

of things as well as the rest of the Forest for future generations and not just for ourselves.

play07:18

So that's my hope and goal.

play07:21

We'll see if we're successful.
