Forestry Commission Map codes?...What are they and where do I get the keys?

[Leigh Robinson]

Hi,

I popped into the Forestry Commission office to get a decent map of my favourite woods. They copied one for free. Much thanks for that.

I noticed their map has a lot of codes on it dotted through the woods e.g.:

a BE/MD 56/56
1026 38
OK/BI/SY
37/37/39

I have no idea what they are although I suspect it tells you about the habitat. If it does and I can get a code, the map will become far more important and useful.

Does anyone know what these codes are and where I can get a key?

Why don't you asked FC?

lookng for a quick easy answer! but you are right. I should give them a call in the morning.....

I think what you have there is compartment 1026 which is 38 hectares in area (these in a circle by any chance?). subcompartment a is a mix of beech and I suspect that is actually MC which is mixed conifer - bothe planted in 1956. The other subcompartment is oak, birch sycamore, planted in 1937and 1939

I'll have a quick look - I suspect the list of species codes might be kicking around on my laptop somewhere...

That is magic!

Thanks. Completley changes the usefulnes of the map. Where/how did you get hold of those codes?

 

[Treemonk]

Occupational hazard - I'm a forester

A question on many peoples lips may be "where can we get hold of these maps for a wide area?" I'm sure FC would be less forthcoming if I walked in and asked for their maps of the Lake District!

 

[Treemonk]

To put this in context - these maps represent the information held in the database of forest data held by the landowner - in this case the FC. The database breaks the woodland into management areas (compartments and sub-compartments) and for each management area holds information on species, age, stocking etc.
These maps are essentially OS base maps with the database info overlaid. The "basic" stock map is normally a 1:10,000 scale. All this comes of the GIS system, so whilst you can increase map scale to 1;25,000 or 50,000 or greater, the level of information shown will decrease.

So, back to the wider area question. To get these maps for the entire lake district, you would end up with a series of stock maps covering the areas managed by the FC. If you asked very nicely at the FC offices, I'm sure you could get these, although please bear in mind the time and resources required to print them off. The question is do you really need this level of detail? or could you do happily with a 1:25,000 - they share a great deal in common after all!
