Woodland Network '10 to 15 yrs 'Just a few trees'
 
    

Procedure Print this form (click here). Choose a few trees of the same kind - in a woodland near by. Fill the form (left part below). Report data of your tree to the database (right part). Then click the button 'Send report' below. Your report will be included in the database immediately. Finally compare information over the Internet. (If you investigate and take measurements of the same tree another year or at another period of the year you can see how your tree has 'changed'.) 

Materials Paper, pen, a Guide to trees, a tape measure or a ruler for measuring the thickness and the height of a tree.

Information about 'the trees'
What kind of tree is it?  
Age of the trees? Approx.
Maybe a tree in the area has been cut down so you can count the annual rings on the stub.
   
Height of the trees
A student holds a stick or a ruler in front of his eyes ... having the tree in the range of his sight. Another student is standing beside the tree measuring the distance X - which the first student sees as 1/10 of the ruler.
The height of the tree is 10X meter ( if x=1,12m then the height of the tree is 11,2m)

 
Does your trees have any family on the ground? 
  • No other trees around
  • Same kind of trees around
  • Other trees around
 
Are there any epiphytes (lichens, mosses etc)  growing on tree trunks (stem)?
In some areas there are lichens or mosses growing on the trunk. If there are lot of lichens they indicate there is no or little pollution in the air.
  • Polluted air - no lichens or very small 'spotted' rusky species (looks like a crust on a wound)
  • Fairly pure air - Lichens from A above but also crumpled, 'bushy' lichens. 
  • Pure air - Lichens form A and B above  but also 'bearded' lichens 

 

  • None
  • Some
  • A lot
 
Any visible creatures on tree trunks (stem)?
Are there any insects or other creeping creatures on the bark (including visible trucks or traces)? Some insects are hard to see because of camouflage - they have the same coloring, pattern or shape as the things around them.
  • None
  • Some
  • A lot
 
Any resin blister or wounds on tree trunks (stem)?
Are there any resin blisters on the trunk? (resin = a sticky substance that is produced by some trees)  If you answered Yes - it's a bad sign of health. The tree may not feel very well!
  • None
  • Some
  • A lot
 
Deformation of leaves or needles ?
.
If some leaves are different - a bad sign -  there might be an excessive amount of insects,  corroded leaves etc.. The tree may not feel very well! 
  • None
  • Some
  • A lot
 
Discoloration of leaves or needles?
Are there any discolored leaves? Why discoloration?  Maybe there is a road close to the woodland - exhausted gases from cars. Maybe the tree doesn't get enough nourishment etc. Another factor - the tree may not feel very well.
  • None
  • Some
  • A lot
 
Naked branches?
Are there any branches that have lost their leaves (or needles)? If your answer is YES, then it's a bad sign. Another factor - the tree may not feel very well.
  • None
  • Some
  • A lot
 
Information about environment and health
Trees like all other green plants make part of their own food which animals can't. From air (carbondioxide) and water  plants make carbohydrates (or 'carbon-water') provided that there is enough light and nourishment.
Does your tree get enough light. 
It might be "covered" by other trees.
  • Some
  • It gets a lot of light
  • It's standing in shadow
 
Does the tree get enough water from the ground?
Take some soil or sand from the ground and crumble it between your fingers, then throw it away. If you still have some soil on your skin then the soil is moisty, meaning there is water for the tree. If the soil is dry then there is a risk the tree will wither.
  • The ground is dry
  • The ground is moisty
  • The ground is very wet
  • The ground is wet due to rain, snow etc.

 
What's the color of the soil?  
Sandy soil could mean there is a deficit in nourishment.
A blackish soil could mean there is a high content of dead organic matter ( nourishment ).
  • Sandy
  • Mixed
  • Dark
 
 
Is the air polluted from traffic or chimneys?
If there is a bad smell in the air. Where do you think it's coming from? Are there any factories or chimneys around?  Smell could be pollution which may affect the tree.
  • Not polluted
  • Smelly air - not dentified
  • Polluted area
 
 
Our opinion ...about the environment.
  • Good
  • Not so good
  • Bad for health of trees
 
 
Our opinion ...about the health of your trees.  
  • The trees looks good and prosperous
  • Most of the trees looks prosperous
  • The trees don't look very happy
  • The trees are almost dead
  • The trees are dry and dead (easy to break)
